How to open a bicycle lock. Combination lock for a bicycle - what to do if you forgot the code and how to open it. What to do if you forgot the code

Combination bike locks are popular among owners of two-wheeled vehicles - they are easy to use and reliably protect the bike from hacking attempts. Especially inexperienced thieves bypass combination locks, since not everyone knows how to select a combination on public display of curious onlookers, while maintaining composure.

It would seem that if combination bicycle locks are so convenient, then no problems with their operation should arise in principle, but in practice things are different. The most common problem when using combination bike locks is a forgotten code.

How to open a bicycle lock if you forgot the code

To open such a lock, you need to set the correct digital combination on the rotating toggle switches, but what if you sent the bike into hibernation, and in the spring you found that you could not remember the code? Don't panic, we'll show you how to open your bike lock if you forgot the code.

Algorithm of actions in case of a forgotten code from a bicycle lock

You can pick up a code for any combination bike lock - it will take time, but if you do not rush, then everything will work out. It’s the thief on the street who doesn’t have the opportunity to calmly sort out combinations, while you and your bike can comfortably settle in the garage and start simple manipulations.

  • you need to try digital combinations - this must be done at each level, alternately setting numbers from 0 to 99;
  • on the stopper, the code locks have a division - each digit must go through it strictly 3 times in order to go to the next level;
  • manipulations for alternately placing numbers must be repeated at each level;
  • when you reach level 3, turn the dial counterclockwise so that each of the numbers crosses the mark - at the moment when the code is correct, the lock will unlock.



Another option for opening the code lock:

  • first we put all the numbers in the same position - 1111;
  • then we change the combinations of numbers, simultaneously pulling both ends of the device with each of the combinations;
  • your task is the appearance of a gap that will indicate the correct neighborhood of two numbers;
  • proceed further in the same mode - change the numbers and drag until gaps appear between all the numbers;
  • once the correct combination is established, the lock will unlock.



What if, in the process of manipulation, you damaged the lock, or simply due to age, it failed? So, it's time to buy reliable modern protection for your bike. For example, on the website of our partners bikelock.ru you can find interesting promotional offers for high-quality bike locks. We were given a promotional code for a 15% discount on the entire range, and we are sharing with you: velosreda15.

The worsening crime situation in big cities requires the adoption of urgent measures to counter the lovers of easy money.

Today you will not see a single bike on the street that is “not chained” to a pole or to the fence of a special bike stand.

This is the only way to hope for its safety while you make purchases or pay utility bills. But which locking device to choose? So that it is reliable and able to withstand hacking attempts.

Among all the variety of models, the most reliable is the combination lock for your bike. It features a solid construction and cannot be opened with a lockpick. And it takes a long time to select the code, so the chances of stealing it with such protection are minimal.

Combination locks - application specifics

What is the difference between these locking mechanisms? First of all, the principle of operation and the method of opening and closing. Unlike traditional mechanical models, it does not require a key. To close the Cyclotech bike lock, you just need to enter a combination of numbers. Moreover, such models are usually supplied from the factory with the code 000 - to make it easier to understand the principle of their operation. And then you have the right to choose the combination of numbers you like.

The simplest models of such locks have a mechanism with several coded disks for entering an invented combination of numbers that replace the key. Each disc allows you to enter one code character and is part of the locking mechanism.

We watch the video, the criteria for choosing a lock:

It is these models that are widely used in cases, suitcases, as well as on bicycle blocking cables. But at the same time, they are one of the less reliable among bicycle combination locks. Because when you enter the correct character, a click is heard, which crackers are guided by. A disadvantage is also a small number of combinations, it does not exceed 1000 and can be selected within half an hour.

Types of locks for bicycles and their features

When choosing a locking device for your bike, you need to understand its characteristics, such as reliability and ease of use. After all, there are no guarded bike parking lots in Russia, and fences, poles and trees are usually places for bike parking.

Therefore, the first thing you have to pay attention to is the length of the loop.

However, for the safety of the bike, you need to evaluate the thickness of the cable, as well as the type of mechanism and the material used to make it.

Next, we proceed to the choice of the type of locking mechanism. They can be keyed or bicycle locks with a code. In terms of reliability, there is not much difference between them. Therefore, everyone chooses the most convenient model for themselves. But you need to pay attention to the presence of mounts that will allow you to carry this mechanism with you.

If we consider design features locks for bicycles, the U or D-shaped option is considered the most reliable. Using such a device, you can even chain a folding bike. Its advantages include the impossibility of biting or sawing it, as well as using a master key to open it.

But this model also has its drawbacks - a small possibility of coverage. Here you have to choose what to fasten - a frame or a wheel. But they are both not very optimistic. Since in the first option, your bike may be left without wheels at all, and in the second, without one of them. And it will not work at all to fasten to a large diameter support.

Watch the video, test the locks:

The ideal choice is such a mechanism, the use of which allows you to thread the lock through the rear wheel so that it covers the frame. In addition, the considered model of the lock has a rather large weight and it is not very convenient to carry it with you.

Locking device with a chain - there are a large number of such models, but not all of them are highly reliable. After all, if an ordinary iron chain is used, then it will not become an obstacle for a thief. If it is their improved alloy, then the reliability will increase significantly, but the price will increase accordingly. The length of such locks may vary, but usually it is enough to entangle rear wheel and frame and chain it to an object of decent diameter. However, the weight of such a mechanism is quite large, which creates certain inconveniences.

Watch the video, test bike locks:

There are Cyclotech code locks with a cable instead of a chain. They are more compact in size and weight. Cables that can stretch to a given length are considered especially convenient. Such a model is most convenient for transportation, but at the same time it can be eaten with reinforcing scissors.

There are bike locks made of plates, but it only allows you to attach a frame. And the plates themselves will not become an obstacle for a burglar who has a special tool.

Having considered various types of locks, each of you will be able to draw the necessary conclusion.

Popular Models

If you settled on a cable lock model, then pay attention to the bicycle lock with the Cyclotech brand code. It is equipped with an LED, which makes the lock visible in the dark and convenient for those who travel in dark time days.

It is small and light and easy to use. The standard code for new models is 0000, but it can be changed without difficulty.

The lock is made of high-strength steel, which makes it reliable and durable. The length of the cable is 120 cm, it is enough to chain the bike to an object of a sufficiently large diameter. The cost of such a model is about $ 15 and is quite affordable for everyone.

What to do if you forgot the code

On the one hand, a combination lock is convenient because it does not need a key, which means it cannot be lost. But on the other hand, there is a possibility that you will forget the code, and how then to open the bicycle combination lock in such a situation?

Forgot password, help to open:

You will have to pick it up, and to do this, go through all possible combinations. At each level, you must select a number between 0 and 99, and on the fixed part of the lock there is a mark that the division of the selected number goes through three times before you move on to another level. This must be done at each level, and only at the third level you have to rotate the disk counterclockwise until the selected number reaches the mark. If the code has been entered correctly, the lock will open.

I would like to note that none of the existing anti-theft locks can guarantee 100% protection of the bike. Therefore, do not leave it unattended for a long time or in a sparsely populated place. And even more so, you don’t need to throw your bike without chaining it to a stationary object.

Watch the video, good advice:

Choose the most secure lock taking into account the recommendations of experts. And what it will be with a key or code - depends on your desire. If you never lose your keys and trust traditional models more, then you can choose them. Although in terms of their reliability, the mechanical and bicycle locks of the Cyclotech brand are identical.

Only staples and chains are really reliable in terms of cutting / biting:

The chain weighs a lot, rattles. The bracket also weighs more than a “regular” lock, plus it can’t cling to everything.

I don't want to get involved with either one or the other. I understand that even if it is such a reliable lock, I will still try not to let the bike out of sight. An exception is the parking lot at our place of work (although there were cases of snacking and theft). Well, you can’t chain the whole bike:


And then it can always end with "partial hijacking":

In "regular" cables, I pay attention to the following points:

1) Cable thickness.
Some look absolutely ridiculous (about 4-5mm in diameter). With my head, I understand that thick ones are not too difficult to bite, but thin ones, sometimes it seems, you can just tear them by pulling harder on the frame.

2) Form.
Sometimes it's just a loop, but sometimes it's a pig's tail:

I prefer the second - it is more compact when transporting, but when fastening it is longer than a regular loop. It is convenient to carry it, for example, on the steering rack:


3) Key or code.
Most code codes can be opened by hand in a couple of minutes - it's enough to understand how they work. Opening your own lock with a key is much faster. The code must not be forgotten to be reset after opening / closing. The key can be given to a friend, and then taken back (the said code cannot be taken away). The key can be opened in low light.
So just the key.

4) Opening spring.
When I turned the key - the lock should "shoot back" itself. At least a few millimetres. So that you can turn the key back, remove it, and only then remove the open lock. If this spring is not present, it is necessary, while holding the key in the turned state, to open the lock with the other hand - this is inconvenient.

5) Ability to close without a key.
There are still locks, to close which, you need to insert the key, turn it, close the lock, turn the key back. This is also inconvenient. It is convenient when the lock can be latched without a key.

6) Key strength.
Once upon a time in my childhood I had a lock with a ma-a-scarlet little key. Once I turned it, but it did not turn, but broke. Part of the key was left in the lock. Fortunately, the bike was not fastened at that moment - I opened the lock on the bike just to buckle up. I had to go home and honestly cut the cable. What a trauma from childhood :)
Now there are practically no such ones, but I still pay attention to the key when buying.
From the point of view of the strength of the key and its non-jamming when opening, round keys compare favorably:


But now, for some reason, such castles are very rare.

7) Shutter covering the well.
They also like to seize locks from sand and other dirt that gets into them. So a curtain covering the well will be useful:

In practice, finding a castle that meets all the necessary criteria is quite simple. So it's more like a check-list - what not to forget to check before paying. But I don't know how to check it all in the online store. So behind the lock, as well as for other small things (pump, beacons, gloves) - it's easier to look at the bike market once.

Combination lock for bicycle - popular models

What is a combination bike lock

Description

Operating principle

What are

There are several types of locking devices with a code:

  1. chain locks.
  2. cable locks.
  3. plate locks.
  4. wheel locks.

How to choose

  1. One of the most important parameters indicating the reliability of a product is the thickness and quality of the metal used in it, the thicker it is, the better, preference should be given to hardened steel products.
  2. You should immediately choose a lock that, according to its functional features, will meet specific operating conditions and security requirements.

Main selection criteria

  • The convenience of use. Since it is very difficult to find a bicycle park with guarded parking in every city in Russia. As a rule, arbitrarily chosen fences, trees and power poles usually become a parking place for a bicycle. Therefore, one of the main criteria for choosing between one or another locking device is the presence of the longest possible loop. The longer it is, the more universal the locking device is, and a bicycle, for example, can be chained to the nearest tree from the store in order to see it from the window of the building, and not be left hundreds of meters near an iron fence.
  • Reliability. It is almost impossible to crack a code lock right away, and it takes a very long time to select a code by brute force combinations. Attackers often, in general, do not spend time on this and use biting tools, and sometimes even files and hacksaws, breaking not the lock itself, but its loop. Therefore, when choosing a combination lock for a bicycle, you should also pay attention to the thickness of the locking cable or chain, as well as the presence of weak points and the material from which the locking mechanism is made.

How to use correctly

To use the code lock you need:

  1. Next, you need to set your own set of numbers on the already open lock, which will be the key to the lock, the combination should be chosen easy to remember so that it cannot be forgotten.


Not less than important aspect to protect the bike is the correct fastening of the lock on it:

  1. When used correctly, the lock loop should be threaded through the rear wheel with the obligatory capture of the frame as well.
  2. It is not recommended to install a U-lock on the crossbar between the steering wheel and the seat, as with a sufficiently large force it turns into a lever with which you can break off the lock.
  3. The front wheel is weak point of all models of bicycle transport, since it is the easiest to dismantle, therefore it is desirable that the lock loop also covers it, but, as a rule, its length is not enough, therefore it is recommended to block the front wheel with a second lock.

Cheap models of code locks have become very popular in all sorts of diplomats and suitcases, and also in the design of fastening cables for bicycle transport. But, however, they are not very reliable means against the theft of a bicycle by a thief. The fact is that even if you accidentally enter one correct number, a cheap lock makes a click, listening to such clicks, a thief can pick up the whole combination.

Advantages and disadvantages

Overview of the best models

  1. An alternative design is a lock with a chain, but for the most part they do not differ high level reliability. Because, reliability in this case is determined not by the lock itself, but by the quality of the material from which the chain is made. After all, an ordinary iron chain is not a sufficient barrier for a hijacker. And a real high-strength alloy chain costs decent money. The length of such locks with a chain can vary, but, as a rule, it is quite enough to securely clasp not only the rear wheel with the frame, but also chain them both to an ordinary pole or a small tree. The disadvantage of this option is very big weight a locking device with a chain, which leads to certain inconveniences, such a lock cannot be carried in your pocket.
  2. They, unlike chain locks, take up less space and also weigh less. The most convenient in everyday use are cables with the ability to stretch. This version of the locking device is very convenient on the road, but its cable will not withstand even ordinary rebar scissors. Therefore, such models provide good protection only on busy city streets, where no thief dares to use tools to cut the cable in front of passers-by.

An example of a good U or D-shaped lock is the GIANT model.


Among products with a chain, the TONYON732 combination lock is the best option.


A good device that combines reliability and convenience can be considered a locking device with a steel cable under the Etook brand.


Characteristics

Price

  1. The price of the device from the company GIANT about 1700 rubles.
  2. Model price
  3. The price of the Etook product is 1500 rubles.

What to do if you forgot the code

Everything here is also quite simple. But unlike a thief, who, in front of everyone and waiting for the arrival of the owner of the bike, cannot sort out the code to the lock for half a day, the owner of the bike can do this, for example, in his garage.

How to open

  1. Set the maximum number of obstacles for bike theft, don't be afraid to look paranoid, by installing a second lock, evaluating the protection of the bike, the thief will not waste time and follow the path of least resistance in search of a less secure vehicle.

Bicycle lock - popular models

  • Coded door lock - basic tips

    http://hqsignal.ru

    • Let's make a reservation right away: I do not consider my bike thefts to be immoral, and I am not tormented by remorse. I don’t need money, I have a higher education and a permanent job, I don’t sell these bikes on commission later - I’m interested in the process itself, excitement and a sense of risk. This is not kleptomania, but excitement and a special kind of addiction. I won’t touch a poor student, but I’ll punish an absent-minded “puncher”. Therefore, to begin with, let's define what advice and recommendations I give for people who value their bike. It may not be expensive from a material point of view, but the owner keeps it in decent condition and considers it the main way of transportation. So, for all of you, I have bad news: any lock or chain can be eaten with hydraulic shears. They weigh 3-5 kg ​​and measure about 60 cm, which means that any thief can safely put them in a bag or backpack and leave you without a bike in a couple of minutes. But there is also a good one: such tools are available only to pros who steal dozens or even hundreds of bicycles per season. The bulk of the hijackers are banal drug addicts with wire cutters and hacksaws. They try to sell a stolen bicycle at any price in the nearest thrift store or sell it to passers-by on the street for 1000-2000 rubles.

    But when choosing locks and chains, there are a couple of fundamental points. First of all, weight - you will always have to carry it with you in a bag or fastened to the frame, so more than 1.5-2 kg will be inconvenient. Secondly, the thickness of the bracket (if it is a U-lock type lock) should be the larger, the better. If this is a chain, then the links must be reliably welded, the number of strands must be sufficient, and the method of their interlacing must be reliable. You can also buy a steel twisted cable (“casing” type), it is quite reliable if the cores are intertwined many times, and the cable itself is tucked into a sleeve made of durable plastic compound. Pay attention to the reliability of the body and the lock cylinder (the place where the key is inserted when opening) - everything must be firmly assembled and firmly connected to each other, not to hang out or rattle. Otherwise, you can not bite the lock shackle, chain or cable, but simply knock out the cylinder and the lock will open. I did this a couple of times. Personally, I recommend the Kryptonite U-Lock protection - these locks are successfully used on the streets of New York, San Francisco and London, where the number of bicycle thieves and their aggressiveness is very high.

    The easiest way to lose your bike is to leave it at the entrance. Even if there is an intercom on the door, you can always call any apartment, introduce yourself as a criminal investigation officer or a postman, and they will open the door for you. After that, it’s easy to bite the locks and chains, or even cut off a piece of the railing altogether. Trust me, the vast majority of thefts happen this way. If you leave your bike outside, fasten it in a visible place. If you are sitting in a cafe or bar, buckle up so that you can see out the window. Although there have been cases when the bike was stolen right in front of the astonished owner, but these are already “show-offs”, hardly anyone wants to be substituted so much.

    The classic gop-stop has not been canceled either. You will be taught ways to get out of such situations in self-defense courses, but complete scumbags do this, so sometimes it’s better to give it away - you’ll be more whole. A more intelligent way is to ask for a "ride", when the victim herself gives the bike away, and then can't prove anything. And if you think that there are few of them, then you are greatly mistaken. Tips on how to avoid this are standard: do not drive through dubious areas at night, do not stop if they try to stop or grab your clothes, go around places where marginalized individuals gather.

    If your bike is still stolen, then there is little chance of finding it, especially if a professional worked. Go to the regional thrift stores a couple of times and go to the Juno market on the day of the theft - maybe your pet will pop up there. After a couple of days, try to monitor the Avito ad site - stolen bikes are often put up for sale there.

    If your bike is of a rare brand, unusual color or assembled from rare parts - rejoice and post an ad in social media, go to the police and, just in case, write a statement. The likelihood that the bike or parts will pop up at flea markets or forums, or that your iron horse will be noticed by friends on the streets of the city, is very high. To be honest, that's why I rarely touch them.

    We are not afraid that security technologies are developing. Yes, sensors and GPS beacons have appeared that can be attached inside the seat tube of a bicycle, and in case of theft, they can be found by geolocation. The cost of such devices is still high, and they are not yet installed on budget city bikes. Of course, if you have a two-wheeled unit for several thousand dollars at your disposal, it is quite possible to think about such a safety net. Only, as a rule, they think about it after the fact, after a sad experience.

    Today, the price of an average bicycle is about 10 thousand rubles and frequent thefts of bicycles, especially in big cities, are not just hooligan actions, but a business put on stream. Today, a rare owner of his two-wheeled horse does not care about theft protection. The main and most reliable means of theft is a combination lock.

    Description

    Combination locks for two-wheeled vehicles are famous for their simplicity of device and, due to their reliability, are not subject to a burglar with any master key. And one thought to sit in front of everyone and select the code for someone else's bike terrifies any thief.

    Therefore, realizing that the lock is opened only by a code and, having no other options to crack it, even an experienced thief will not even try to open it, but will simply go looking for easier prey.

    Operating principle

    What is the difference between a combination lock and conventional locking devices on a turnkey basis. Mainly by the very principle of operation of locking and unlocking. It differs from ordinary models in the absence of a key, which is necessary for mechanical counterparts, which can be stolen, picked up and even replaced with a master key. The combination lock for the bike is locked with a numerical key, which is stored only in the head of the owner of the bike and is a combination of numbers.

    When buying, for ease of familiarization with the principle of operation of protective devices, such locks have a factory code of 000, which the owner can easily change to a combination of numbers that is convenient for him.

    What are

    The simplest versions of such devices have code disks in their design, by rotating which you can change combinations of numbers that replace the key. One disk is responsible for changing one digit, and a set of such disks is an element of the locking mechanism.

    There are several types of locking devices with a code:

    1. U-shaped or D-shaped locks.
    2. chain locks.
    3. cable locks.
    4. plate locks.
    5. wheel locks.

    How to choose

    Before you buy the lock you like for your bike, you need to understand whether it is right for you in terms of its characteristics, reliability and comfort of use.

    Characteristics of the lock, which you need to pay attention to when buying:

    1. First of all, you should pay attention to the price of the lock and the brand of the manufacturer, since cheap low-quality models from the Chinese market can only fit as a free souvenir to a thief.
    2. One of the most important parameters indicating the reliability of the product is the thickness and quality of the metal used in it, the thicker it is, the better, preference should be given to hardened steel products.
    3. Equally important is the design of the encoder itself, it should have a sufficiently large number of combinations and, when typing numbers with clicks, not give the thief the correct combination.
    4. You should immediately choose a lock that, according to its functional features, will meet specific operating conditions and security requirements.

    As a rule, one lock is not enough to completely protect the entire bike. Therefore, it is recommended to choose at least two locks at once, one of which must be equipped with a powerful and long loop, for example, in the form of a chain made of high-strength alloy, so that even with a strong desire it would be impossible to tear the bike off the fixed support to which it is fastened.

    Such a chain will stop any thief from stealing the entire vehicle, but a thief can profit from the wheels from a steel horse. Therefore, it is better to purchase, in addition to the first lock, another one that is lighter and more compact, for example, with a cable to wrap around both wheels and the frame. Of course, these are additional costs and certain inconveniences, but a rare thief will dare to approach a bicycle correctly fastened with several locks.

    Main selection criteria

    • The convenience of use. Since it is very difficult to find a bicycle park with guarded parking in every city in Russia. As a rule, arbitrarily chosen fences, trees and power poles usually become a parking place for a bicycle. Therefore, one of the main criteria for choosing between one or another locking device is the presence of the longest possible loop. The longer it is, the more universal the locking device is, and a bicycle, for example, can be chained to the nearest tree from the store in order to see it from the window of the building, and not be left hundreds of meters near an iron fence.
    • Reliability. It is almost impossible to crack a code lock right away, and it takes a very long time to select a code by brute force combinations. Attackers often, in general, do not spend time on this and use biting tools, and sometimes even files and hacksaws, breaking not the lock itself, but its loop. Therefore, when choosing a combination lock for a bicycle, you should also pay attention to the thickness of the locking cable or chain, as well as the presence of weak points and the material from which the locking mechanism is made.

    How to use correctly

    To use the code lock you need:

    1. By default, the combination lock has a standard factory code of 000 when purchased, by setting this combination you can open the lock.
    2. Next, you need to set your own set of numbers on the already open lock, which will be the key to the lock, the combination should be chosen easy to remember so that it cannot be forgotten.
    3. After the invented combination is set on the lock, you should first check its performance simply by slamming the lock and shifting all the numbers, if the lock does not open, then the locking device is working.
    4. Now you need to check if the code is entered correctly, for this they set the combination that was before the lock was closed, if the lock opens, then the code is correct and you can safely fasten the bike to the parking lot.


    An equally important aspect for protecting a bicycle is the correct fastening of the lock on it:

    1. When used correctly, the lock loop should be threaded through the rear wheel with the obligatory capture of the frame as well.
    2. If the lock has insufficient loop coverage, it will be correct to install it only on the rear wheel, but always inside the frame, so the wheel will lock in it and they cannot be separated.
    3. It is not recommended to install a U-lock on the crossbar between the steering wheel and the seat, as with a sufficiently large force it turns into a lever with which you can break off the lock.
    4. The front wheel is the weak point of all models of cycling, since it is the easiest to dismantle, so it is desirable that the lock loop covers it, but, as a rule, its length is not enough, so it is recommended to block the front wheel with a second lock.
    5. Fasten the bike only to immovable, non-removable and non-separable objects so that the lock loop cannot be removed, for example, simply by lifting the bike over your head.

    How secure is a bike lock?

    Cheap models of code locks have become very popular in all sorts of diplomats and suitcases, and also in the design of fastening cables for bicycle transport. But, however, they are not very reliable means against the theft of a bicycle by a thief. The fact is that even if you accidentally enter one correct number, a cheap lock makes a click, listening to such clicks, a thief can pick up the whole combination.

    Moreover, such models, as a rule, have a rather small selection of combinations, not exceeding 1000 combinations, which an experienced cracker can sort out in half an hour. Thus, when choosing a combination lock for your bike, you should pay attention not only to the price, but also to the quality of the locking mechanism itself. And a sufficiently large number of combination options will protect the lock from hacking no worse than a safe in a bank.

    Advantages and disadvantages

    1. The devices that close the wheel with the frame are reliable and will not allow a thief to leave on a bicycle or even drive it away, but it is easy to take it away or take it away by loading it into a car.
    2. A cheap plate lock is also not a big obstacle, especially since it is not difficult to bite through the plates, which themselves often break, even with ordinary metalwork scissors.
    3. Cable locks are both convenient, compact and lightweight, but again, such a cable can be eaten with a tool.
    4. The most reliable is a chain lock made of hardened steel, even a hacksaw will not take it, but the weight of such a device is more than a kilogram and can be quite burdensome.
    5. The U-Lock is ideal in every way, and compact and strong, but not very versatile, as it has a small grip and is designed specifically for fastening to small diameter pipes, such as in ordinary bike racks.

    Overview of the best models

    1. In terms of design, the most secure type of locks are U- or D-shaped devices. With a lock of this shape, it will not be a problem to fasten even a folding bike. The advantage of such combination locks is maximum reliability in terms of the fact that it is impossible to bite or cut them. But even such models have their drawback in the form of a small loop coverage, which means that you have to choose between a fastened wheel or a frame. In both cases, there is no sufficient guarantee that the bike will remain in its place safe and sound. Not to mention the fact that such locks are not designed to be fastened to any pillars and supports of large diameter.
    2. An alternative design is a lock with a chain, but for the most part they do not have a high level of security. Because, reliability in this case is determined not by the lock itself, but by the quality of the material from which the chain is made. After all, an ordinary iron chain is not a sufficient barrier for a hijacker. And a real high-strength alloy chain costs decent money. The length of such locks with a chain can vary, but, as a rule, it is quite enough to securely clasp not only the rear wheel with the frame, but also chain them both to an ordinary pole or a small tree. The disadvantage of this option is the very large weight of the locking device with a chain, which leads to certain inconveniences; you cannot carry such a lock in your pocket.
    3. Combination locks are also produced in which the chain is replaced by a cable. They, unlike chain locks, take up less space and also weigh less. The most convenient in everyday use are cables with the ability to stretch. This version of the locking device is very convenient on the road, but its cable will not withstand even ordinary rebar scissors. Therefore, these models provide good protection only on busy city streets, where no thief dares to use tools to cut the cable in front of passers-by.

    An example of a good U or D-shaped lock is the firm's model GIANT.


    Among products with a chain, the best option is a combination lock TONYON732.


    A good device that combines reliability and convenience can be considered a locking device with a steel cable under the brand Etook.


    Characteristics

    1. The GIANT D-shaped lock is made of steel and has a combined design, since in addition to the steel bracket it also combines a steel cable, which, in terms of functionality, allows it to replace two conventional bicycle locks.
    2. The TONYON732 combination lock has a steel chain over a meter long.
    3. The Etook locking device is equipped with a steel cable with a cross section of 12 millimeters and a length of about one and a half meters.

    Price

    1. The price of the device from the company GIANT about 1700 rubles.
    2. Model price TONYON732 does not exceed 3000 rubles.
    3. Product price Etook 1500 rubles.

    What to do if you forgot the code

    The combination lock is very convenient to use, since you do not need to constantly carry the key to it with you, there is no chance of losing it, or breaking it in the well at the most crucial moment. But it happens, for example, that a person locks the lock with a code, puts the bike in the garage for the winter, and takes it out in the summer, but does not remember the code from the lock. How then to be?

    Everything here is also quite simple. You can pick up a code for any combination lock by sorting through all the combinations; here the whole snag is that this will take a lot of time. But unlike a thief, who, in front of everyone and waiting for the arrival of the owner of the bike, cannot sort out the code to the lock for half a day, the owner of the bike can do this, for example, in his garage.

    How to open

    To try all combinations of numbers and unlock the lock, you will need to set numbers from 0 to 99 in turn at each level, and there is a division on the locking element of the lock, which each number must go through three times before moving to the next level.

    The operation must be repeated with each level, and only after reaching the third, you will need to turn the disk counterclockwise until a certain number crosses the mark. When the code is correct, the lock will unlock.

    1. Set the maximum number of obstacles for bike theft, don't be afraid to look paranoid, by installing a second lock, evaluating the protection of the bike, the thief will not waste time and follow the path of least resistance in search of a less secure vehicle.
    2. In no case should the castle lie on the ground, since the thief has the opportunity to use it as an anvil and damage the castle even with an ordinary cobblestone.
    3. Try to park your bike where you can see it, even if you are in a building.
    4. Use quality locks from trusted brands.
    5. Focusing on the crime situation in your area, think about protecting the steering wheel and seat in advance, as some thieves are engaged in removing any parts from vehicles.

    Like banks, none of the modern locks guarantees 100% inviolability of your property. Therefore, you should never leave your iron friend for a long time without attention, and even in a deserted place.

    Let's make a reservation right away: I do not consider my bike thefts to be immoral, and I am not tormented by remorse. I don’t need money, I have a higher education and a permanent job, I don’t sell these bikes on commission later - I’m interested in the process itself, excitement and a sense of risk. This is not kleptomania, but excitement and a special kind of addiction. I won’t touch a poor student, but I’ll punish an absent-minded “puncher”. Therefore, to begin with, let's define what advice and recommendations I give for people who value their bike. It may not be expensive from a material point of view, but the owner keeps it in decent condition and considers it the main way of transportation. So, for all of you, I have bad news: any lock or chain can be eaten with hydraulic shears. They weigh 3-5 kg ​​and measure about 60 cm, which means that any thief can safely put them in a bag or backpack and leave you without a bike in a couple of minutes. But there is also a good one: such tools are available only to pros who steal dozens or even hundreds of bicycles per season. The bulk of the hijackers are banal drug addicts with wire cutters and hacksaws. They try to sell a stolen bicycle at any price in the nearest thrift store or sell it to passers-by on the street for 1000-2000 rubles.

    But when choosing locks and chains, there are a couple of fundamental points. First of all, weight - you will always have to carry it with you in a bag or fastened to the frame, so more than 1.5-2 kg will be inconvenient. Secondly, the thickness of the bracket (if it is a U-lock type lock) should be the larger, the better. If this is a chain, then the links must be reliably welded, the number of strands must be sufficient, and the method of their interlacing must be reliable. You can also buy a steel twisted cable (“casing” type), it is quite reliable if the cores are intertwined many times, and the cable itself is tucked into a sleeve made of durable plastic compound. Pay attention to the reliability of the body and the lock cylinder (the place where the key is inserted when opening) - everything must be firmly assembled and firmly connected to each other, not to hang out or rattle. Otherwise, you can not bite the lock shackle, chain or cable, but simply knock out the cylinder and the lock will open. I did this a couple of times. Personally, I recommend the Kryptonite U-Lock protection - these locks are successfully used on the streets of New York, San Francisco and London, where the number of bicycle thieves and their aggressiveness is very high.

    The easiest way to lose your bike is to leave it at the entrance. Even if there is an intercom on the door, you can always call any apartment, introduce yourself as a criminal investigation officer or a postman, and they will open the door for you. After that, it’s easy to bite the locks and chains, or even cut off a piece of the railing altogether. Trust me, the vast majority of thefts happen this way. If you leave your bike outside, fasten it in a visible place. If you are sitting in a cafe or bar, buckle up so that you can see out the window. Although there have been cases when the bike was stolen right in front of the astonished owner, but these are already “show-offs”, hardly anyone wants to be substituted so much.

    The classic gop-stop has not been canceled either. You will be taught ways to get out of such situations in self-defense courses, but complete scumbags do this, so sometimes it’s better to give it away - you’ll be more whole. A more intelligent way is to ask for a "ride", when the victim herself gives the bike away, and then can't prove anything. And if you think that there are few of them, then you are greatly mistaken. Tips on how to avoid this are standard: do not drive through dubious areas at night, do not stop if they try to stop or grab your clothes, go around places where marginalized individuals gather.

    If your bike is still stolen, then there is little chance of finding it, especially if a professional worked. Go to the regional thrift stores a couple of times and go to the Juno market on the day of the theft - maybe your pet will pop up there. After a couple of days, try to monitor the Avito ad site - stolen bikes are often put up for sale there.

    If your bike is of a rare brand, unusual color or assembled from rare parts - rejoice and post an ad on social networks, go to the police and, just in case, write a statement. The likelihood that the bike or parts will pop up at flea markets or forums, or that your iron horse will be noticed by friends on the streets of the city, is very high. To be honest, that's why I rarely touch them.

    We are not afraid that security technologies are developing. Yes, sensors and GPS beacons have appeared that can be attached inside the seat tube of a bicycle, and in case of theft, they can be found by geolocation. The cost of such devices is still high, and they are not yet installed on budget city bikes. Of course, if you have a two-wheeled unit for several thousand dollars at your disposal, it is quite possible to think about such a safety net. Only, as a rule, they think about it after the fact, after a sad experience.

    And such a device is used by locksmiths who come to open slammed doors without damaging the lock. And it costs - very little.
    Yu - locks and other brackets with a large opening - often bite or open with hydraulics, a simple jack with a rather primitive nozzle. And not petty thieves, but municipalities. And to hang out exactly how, here I am not an assistant to thieves.
    So from a small biker, and for a short time - a code on a good lock - a good solution. As well as a lock with a key, and a small trick - for example, a small magnetic insert in the lock hole, which without a strong special magnet - the key cannot be pulled out, and the master key cannot be pushed all the way.
    And if the lead is left for a long time, then there is no reception against scrap, they will not open the lock, so they will break the lead, and take it away as spare parts ...
    And then they just break it. As long as stolen bikes will be bought, they will be stolen. Alas.

    It’s one thing that it’s impossible to imagine that no one would be tempted to buy a bicycle, or accessories for it at half price, especially considering that the current “official” prices for this iron are more and more reminiscent of robbery
    But if you still imagine it, that the demand for "cheap bikes from Europe" will disappear completely, then it is even more difficult for yourself to think of a reason why they still continued to steal them. 23.01.2015 19:25

    I read several Fenman books)) and about opening locks - he wrote a lot that this method is just a farce)
    yes, when the code consists of four digits, it is not difficult to pick up, and when there are more, it is not an easy task.

    24.01.2015 02:48

    But not difficult either - on the same key, of the same type as in the clip - 5 sectors, three positions for each sector.
    3 to the fifth power is just 243 combinations. Digital with the same number - already 100,000. And how many locks bought in a store never receive a new combination from the owner .... And not only bike locks, but also anti-theft in cars ...
    And the weak points left by the developer in the cable and chain ones - then the 8mm chain will be connected to the lock tongue through a 5mm rivet, and hingedly, then the lock body is silumin or brass, then the shackle axis is about 4mm ... about compressing the end of the cable in the aluminum loop with a coupling - for the cheap, it's almost standard. And chains made of supposedly hardened, but in fact only cemented steel - yes, the hacksaw does not take, and the bolt cutter - like dog teeth sausage.
    The castle, even a good one, led only a short-term defense. To buy a drink, eat, or go to the toilet is fine. And for a long time at the office - until the first thief who needed your lead.

    As I understand it, this is a demonstration of the much discussed problem with English locks that are easily broken. Accordingly, U-lok should be viewed with a more complex larva, such as Ongard Brute. Abus also has English castles.

    Exactly. There will always be people like this. And even if there are almost no such people left in Europe, the bicycles leave the wheels in Ukraine and Russia. The mentality in Ukraine will change - "Bicycles from Ukraine" will leave the wheels in Africa.

    Today, the price of an average bicycle is about 10 thousand rubles and frequent thefts of bicycles, especially in big cities, are not just hooligan actions, but a business put on stream. Today, a rare owner of his two-wheeled horse does not care about theft protection. The main and most reliable means of theft is a combination lock.

    Description

    Operating principle

    What are

    There are several types of locking devices with a code:

    1. chain locks.
    2. cable locks.
    3. plate locks.
    4. wheel locks.

    How to choose

    Characteristics of the lock, which you need to pay attention to when buying:

    1. One of the most important parameters indicating the reliability of the product is the thickness and quality of the metal used in it, the thicker it is, the better, preference should be given to hardened steel products.
    2. You should immediately choose a lock that, according to its functional features, will meet specific operating conditions and security requirements.

    Main selection criteria

    • The convenience of use. Since it is very difficult to find a bicycle park with guarded parking in every city in Russia. As a rule, arbitrarily chosen fences, trees and power poles usually become a parking place for a bicycle. Therefore, one of the main criteria for choosing between one or another locking device is the presence of the longest possible loop. The longer it is, the more universal the locking device is, and a bicycle, for example, can be chained to the nearest tree from the store in order to see it from the window of the building, and not be left hundreds of meters near an iron fence.
    • Reliability. It is almost impossible to crack a code lock right away, and it takes a very long time to select a code by brute force combinations. Attackers often, in general, do not spend time on this and use biting tools, and sometimes even files and hacksaws, breaking not the lock itself, but its loop. Therefore, when choosing a combination lock for a bicycle, you should also pay attention to the thickness of the locking cable or chain, as well as the presence of weak points and the material from which the locking mechanism is made.

    How to use correctly

    To use the code lock you need:

    1. Next, you need to set your own set of numbers on the already open lock, which will be the key to the lock, the combination should be chosen easy to remember so that it cannot be forgotten.


    An equally important aspect for protecting a bicycle is the correct fastening of the lock on it:

    1. When used correctly, the lock loop should be threaded through the rear wheel with the obligatory capture of the frame as well.
    2. It is not recommended to install a U-lock on the crossbar between the steering wheel and the seat, as with a sufficiently large force it turns into a lever with which you can break off the lock.
    3. The front wheel is the weak point of all models of cycling, since it is the easiest to dismantle, so it is desirable that the lock loop covers it, but, as a rule, its length is not enough, so it is recommended to block the front wheel with a second lock.

    Cheap models of code locks have become very popular in all sorts of diplomats and suitcases, and also in the design of fastening cables for bicycle transport. But, however, they are not very reliable means against the theft of a bicycle by a thief. The fact is that even if you accidentally enter one correct number, a cheap lock makes a click, listening to such clicks, a thief can pick up the whole combination.

    Advantages and disadvantages

    Overview of the best models

    1. An alternative design is a lock with a chain, but for the most part they do not have a high level of security. Because, reliability in this case is determined not by the lock itself, but by the quality of the material from which the chain is made. After all, an ordinary iron chain is not a sufficient barrier for a hijacker. And a real high-strength alloy chain costs decent money. The length of such locks with a chain can vary, but, as a rule, it is quite enough to securely clasp not only the rear wheel with the frame, but also chain them both to an ordinary pole or a small tree. The disadvantage of this option is the very large weight of the locking device with a chain, which leads to certain inconveniences; you cannot carry such a lock in your pocket.
    2. They, unlike chain locks, take up less space and also weigh less. The most convenient in everyday use are cables with the ability to stretch. This version of the locking device is very convenient on the road, but its cable will not withstand even ordinary rebar scissors. Therefore, such models provide good protection only on busy city streets, where no thief dares to use tools to cut the cable in front of passers-by.

    An example of a good U or D-shaped lock is the firm's model GIANT.


    Among products with a chain, the best option is a combination lock TONYON732.


    A good device that combines reliability and convenience can be considered a locking device with a steel cable under the brand Etook.


    Characteristics

    Price

    1. The price of the device from the company GIANT about 1700 rubles.
    2. Model price
    3. Product price Etook 1500 rubles.

    What to do if you forgot the code

    Everything here is also quite simple. You can pick up a code for any combination lock by sorting through all the combinations; here the whole snag is that this will take a lot of time. But unlike a thief, who, in front of everyone and waiting for the arrival of the owner of the bike, cannot sort out the code to the lock for half a day, the owner of the bike can do this, for example, in his garage.

    How to open

    1. Set the maximum number of obstacles for bike theft, don't be afraid to look paranoid, by installing a second lock, evaluating the protection of the bike, the thief will not waste time and follow the path of least resistance in search of a less secure vehicle.

    Among the mass of anti-theft devices on the market, the most trusted by consumers is a bicycle lock with a code. Unlike traditional devices that are mechanically opened with a key, they require the correct digital combination to be set on the rotating toggle switches to open them.

    Such a lock is fixed on a fixed support (bike rack), entangles quickly removable elements, preventing their removal.

    We emphasize right away that the information below is not posted in order to push anyone to illegal actions. We tell you how to open the lock for those who, due to their own distraction or forgetfulness, have lost the password, and do not consider the option of biting the device with hydraulic scissors.

    If we are dealing with the simplest coding device, similar to what is installed on suitcases and cases, then we will have to deal with only three numerical wheels, which is about 1000 combinations. Enumeration of all possible takes usually no more than half an hour.

    Algorithm of actions if you forgot the code on the bicycle lock:

    1. we set all the numbers to the same position, for example, to 1111. The opening method is to pull both ends of the device with each combination. The goal is the appearance of a small gap that occurs when two numbers are correctly adjacent;
    2. we continue to pull and change the numbers until there are gaps between all the numbers;
    3. when the combination is found correctly, the device will open without problems.

    Advice! If the device that needs to be unlocked is in this moment not on a bicycle, but, for example, found by you in the closet or on the balcony, the above scheme can be slightly simplified by providing tension by winding the lock cable around the back of the chair.

    How to open a Cyclotech bike lock


    The cyclotech code lock is a budget version of a security device that compares favorably with analogs in the same price category in terms of size and price. It is an effective and simple protection against theft, and it is also convenient because you do not need to carry a key with you to open it, which can be lost so easily.

    The device is extremely easy to operate, even a child can handle it. To open, you need to set four toggle switches to the desired digital combination. However, if the code is forgotten or lost forever, you have to sweat a little.

    To open the cyclotech lock, follow the instructions below:

    1. let's start by setting on the first toggle switch any number in the digital range 0-99;
    2. the fixed part of the device has a specially marked mark, each of the selected numbers will pass it three times before moving to the next level;
    3. at each level, you must pass the above mark until the correct cipher is selected. It is possible that in the process of selection you yourself will remember the desired combination;
    4. at the third level, it is necessary to rotate the toggle switch counterclockwise to achieve the correct combination.

    How to open a bike lock without a key


    Cable anti-thefts are extremely popular due to their low cost, but their opening is a matter of minutes, not even minutes, but seconds. You can open a new bicycle lock even without a key. On the Web, you can find dozens of videos describing this comb.

    Therefore, if you have lost the key, do not be discouraged, but proceed according to the following scheme:

    • a knife blade, a half of scissors, a flat screwdriver or any similar device is inserted into the keyhole;
    • the inserted blade scrolls with force along with the larva;
    • "warranty bicycle safety” surrenders literally in a matter of seconds.

    As you can see, a cable lock from a bicycle without a key is opened very simply, therefore, for effective protection, experts insist on using several options for locking devices. Agree, if every student knows how to open the device, it can no longer be considered reliable a priori.

    Do not forget that safety is not something you should save on. As a rule, the cheapest models of locks are the least reliable. Trusting them to protect expensive bikes is at least not reasonable. Purchase anti-theft mechanisms in specialized stores, use products of reliable, trusted brands.

    Let's make a reservation right away: I do not consider my bike thefts to be immoral, and I am not tormented by remorse. I don’t need money, I have a higher education and a permanent job, I don’t sell these bikes on commission later - I’m interested in the process itself, excitement and a sense of risk.

Pay attention to the reliability of the body and the lock cylinder (the place where the key is inserted when opening) - everything must be firmly assembled and firmly connected to each other, not to hang out or rattle.

    Combination lock for bicycle - popular models

    What is a combination bike lock

    Today, the price of an average bicycle is about 10 thousand rubles and frequent thefts of bicycles, especially in big cities, are not just hooligan actions, but a business put on stream. Today, a rare owner of his two-wheeled horse does not care about theft protection. The main and most reliable means of theft is a combination lock.

    Description

    Combination locks for two-wheeled vehicles are famous for their simplicity of device and, due to their reliability, are not subject to a burglar with any master key. And one thought to sit in front of everyone and select the code for someone else's bike terrifies any thief.

    Therefore, realizing that the lock is opened only by a code and, having no other options to crack it, even an experienced thief will not even try to open it, but will simply go looking for easier prey.

    Operating principle

    What is the difference between a combination lock and conventional locking devices on a turnkey basis. Mainly by the very principle of operation of locking and unlocking. It differs from ordinary models in the absence of a key, which is necessary for mechanical counterparts, which can be stolen, picked up and even replaced with a master key. The combination lock for the bike is locked with a numerical key, which is stored only in the head of the owner of the bike and is a combination of numbers.

    When buying, for ease of familiarization with the principle of operation of protective devices, such locks have a factory code of 000, which the owner can easily change to a combination of numbers that is convenient for him.

    What are

    The simplest versions of such devices have code disks in their design, by rotating which you can change combinations of numbers that replace the key. One disk is responsible for changing one digit, and a set of such disks is an element of the locking mechanism.

    There are several types of locking devices with a code:

    1. U-shaped or D-shaped locks.
    2. chain locks.
    3. cable locks.
    4. plate locks.
    5. wheel locks.

    How to choose

    Before you buy the lock you like for your bike, you need to understand whether it is right for you in terms of its characteristics, reliability and comfort of use.

    1. First of all, you should pay attention to the price of the lock and the brand of the manufacturer, since cheap low-quality models from the Chinese market can only fit as a free souvenir to a thief.
    2. One of the most important parameters indicating the reliability of a product is the thickness and quality of the metal used in it, the thicker it is, the better, preference should be given to hardened steel products.
    3. Equally important is the design of the encoder itself, it should have a sufficiently large number of combinations and, when typing numbers with clicks, not give the thief the correct combination.
    4. You should immediately choose a lock that, according to its functional features, will meet specific operating conditions and security requirements.

    As a rule, one lock is not enough to completely protect the entire bike. Therefore, it is recommended to choose at least two locks at once, one of which must be equipped with a powerful and long loop, for example, in the form of a chain made of high-strength alloy, so that even with a strong desire it would be impossible to tear the bike off the fixed support to which it is fastened.

    Such a chain will stop any thief from stealing the entire vehicle, but a thief can profit from the wheels from a steel horse. Therefore, it is better to purchase, in addition to the first lock, another one that is lighter and more compact, for example, with a cable to wrap around both wheels and the frame. Of course, these are additional costs and certain inconveniences, but a rare thief will dare to approach a bicycle correctly fastened with several locks.

    Main selection criteria

    • The convenience of use. Since it is very difficult to find a bicycle park with guarded parking in every city in Russia. As a rule, arbitrarily chosen fences, trees and power poles usually become a parking place for a bicycle. Therefore, one of the main criteria for choosing between one or another locking device is the presence of the longest possible loop. The longer it is, the more universal the locking device is, and a bicycle, for example, can be chained to the nearest tree from the store in order to see it from the window of the building, and not be left hundreds of meters near an iron fence.
    • Reliability. It is almost impossible to crack a code lock right away, and it takes a very long time to select a code by brute force combinations. Attackers often, in general, do not spend time on this and use biting tools, and sometimes even files and hacksaws, breaking not the lock itself, but its loop. Therefore, when choosing a combination lock for a bicycle, you should also pay attention to the thickness of the locking cable or chain, as well as the presence of weak points and the material from which the locking mechanism is made.

    How to use correctly

    To use the code lock you need:

    1. By default, the combination lock has a standard factory code of 000 when purchased, by setting this combination you can open the lock.
    2. Next, you need to set your own set of numbers on the already open lock, which will be the key to the lock, the combination should be chosen easy to remember so that it cannot be forgotten.
    3. After the invented combination is set on the lock, you should first check its performance simply by slamming the lock and shifting all the numbers, if the lock does not open, then the locking device is working.
    4. Now you need to check if the code is entered correctly, for this they set the combination that was before the lock was closed, if the lock opens, then the code is correct and you can safely fasten the bike to the parking lot.


    An equally important aspect for protecting the bike is the correct fastening of the lock on it:

    1. When used correctly, the lock loop should be threaded through the rear wheel with the obligatory capture of the frame as well.
    2. If the lock has insufficient loop coverage, it will be correct to install it only on the rear wheel, but always inside the frame, so the wheel will lock in it and they cannot be separated.
    3. It is not recommended to install a U-lock on the crossbar between the steering wheel and the seat, as with a sufficiently large force it turns into a lever with which you can break off the lock.
    4. The front wheel is the weak point of all models of cycling, since it is the easiest to dismantle, so it is desirable that the lock loop covers it, but, as a rule, its length is not enough, so it is recommended to block the front wheel with a second lock.
    5. Fasten the bike only to immovable, non-removable and non-separable objects so that the lock loop cannot be removed, for example, simply by lifting the bike over your head.

    How secure is a bike lock?

    Cheap models of code locks have become very popular in all sorts of diplomats and suitcases, and also in the design of fastening cables for bicycle transport. But, however, they are not very reliable means against the theft of a bicycle by a thief. The fact is that even if you accidentally enter one correct number, a cheap lock makes a click, listening to such clicks, a thief can pick up the whole combination.

    Moreover, such models, as a rule, have a rather small selection of combinations, not exceeding 1000 combinations, which an experienced cracker can sort out in half an hour. Thus, when choosing a combination lock for your bike, you should pay attention not only to the price, but also to the quality of the locking mechanism itself. And a sufficiently large number of combination options will protect the lock from hacking no worse than a safe in a bank.

    Advantages and disadvantages

    1. The devices that close the wheel with the frame are reliable and will not allow a thief to leave on a bicycle or even drive it away, but it is easy to take it away or take it away by loading it into a car.
    2. A cheap plate lock is also not a big obstacle, especially since it is not difficult to bite through the plates, which themselves often break, even with ordinary metalwork scissors.
    3. Cable locks are both convenient, compact and lightweight, but again, such a cable can be eaten with a tool.
    4. The most reliable is a chain lock made of hardened steel, even a hacksaw will not take it, but the weight of such a device is more than a kilogram and can be quite burdensome.
    5. The U-Lock is ideal in every way, and compact and strong, but not very versatile, as it has a small grip and is designed specifically for fastening to small diameter pipes, such as in ordinary bike racks.

    Overview of the best models

    1. In terms of design, the most secure type of locks are U- or D-shaped devices. With a lock of this shape, it will not be a problem to fasten even a folding bike. The advantage of such combination locks is maximum reliability in terms of the fact that it is impossible to bite or cut them. But even such models have their drawback in the form of a small loop coverage, which means that you have to choose between a fastened wheel or a frame. In both cases, there is no sufficient guarantee that the bike will remain in its place safe and sound. Not to mention the fact that such locks are not designed to be fastened to any pillars and supports of large diameter.
    2. An alternative design is a lock with a chain, but for the most part they do not have a high level of security. Because, reliability in this case is determined not by the lock itself, but by the quality of the material from which the chain is made. After all, an ordinary iron chain is not a sufficient barrier for a hijacker. And a real high-strength alloy chain costs decent money. The length of such locks with a chain can vary, but, as a rule, it is quite enough to securely clasp not only the rear wheel with the frame, but also chain them both to an ordinary pole or a small tree. The disadvantage of this option is the very large weight of the locking device with a chain, which leads to certain inconveniences; you cannot carry such a lock in your pocket.
    3. Combination locks are also produced in which the chain is replaced by a cable. They, unlike chain locks, take up less space and also weigh less. The most convenient in everyday use are cables with the ability to stretch. This version of the locking device is very convenient on the road, but its cable will not withstand even ordinary rebar scissors. Therefore, such models provide good protection only on busy city streets, where no thief dares to use tools to cut the cable in front of passers-by.

    An example of a good U or D-shaped lock is the GIANT model.


    Among products with a chain, the TONYON732 combination lock is the best option.


    A good device that combines reliability and convenience can be considered a locking device with a steel cable under the Etook brand.


    Characteristics

    1. The GIANT D-shaped lock is made of steel and has a combined design, since in addition to the steel bracket it also combines a steel cable, which, in terms of functionality, allows it to replace two conventional bicycle locks.
    2. The TONYON732 combination lock has a steel chain over a meter long.
    3. The Etook locking device is equipped with a steel cable with a cross section of 12 millimeters and a length of about one and a half meters.

    Price

    1. The price of the device from the company GIANT about 1700 rubles.
    2. Model price TONYON732 does not exceed 3000 rubles.
    3. The price of the Etook product is 1500 rubles.

    What to do if you forgot the code

    The combination lock is very convenient to use, since you do not need to constantly carry the key to it with you, there is no chance of losing it, or breaking it in the well at the most crucial moment. But it happens, for example, that a person locks the lock with a code, puts the bike in the garage for the winter, and takes it out in the summer, but does not remember the code from the lock. How then to be?

    Everything here is also quite simple. You can pick up a code for any combination lock by sorting through all the combinations; here the whole snag is that this will take a lot of time. But unlike a thief, who, in front of everyone and waiting for the arrival of the owner of the bike, cannot sort out the code to the lock for half a day, the owner of the bike can do this, for example, in his garage.

    How to open

    To try all combinations of numbers and unlock the lock, you will need to set numbers from 0 to 99 in turn at each level, and there is a division on the locking element of the lock, which each number must go through three times before moving to the next level.

    The operation must be repeated with each level, and only after reaching the third, you will need to turn the disk counterclockwise until a certain number crosses the mark. When the code is correct, the lock will unlock.

    1. Set the maximum number of obstacles for bike theft, don't be afraid to look paranoid, by installing a second lock, evaluating the protection of the bike, the thief will not waste time and follow the path of least resistance in search of a less secure vehicle.
    2. In no case should the castle lie on the ground, since the thief has the opportunity to use it as an anvil and damage the castle even with an ordinary cobblestone.
    3. Try to park your bike where you can see it, even if you are in a building.
    4. Use quality locks from trusted brands.
    5. Focusing on the crime situation in your area, think about protecting the steering wheel and seat in advance, as some thieves are engaged in removing any parts from vehicles.

    Like banks, none of the modern locks guarantees 100% inviolability of your property. Therefore, you should never leave your iron friend for a long time without attention, and even in a deserted place.

    Bicycle lock - popular models

  • Coded door lock - basic tips

    The most popular options are cable locks for attaching a bike. However, situations are not uncommon when the owner himself has lost access to the protective device. In such cases, opening bicycle locks with your own hands will help.

    Types of bike locks

    The safety of this type of transport is constantly evolving and global brands offer systems different levels security. They can be divided into the following types:

    1. Cables with a padlock. More expensive options use a chain. Such a lock requires a key, and it can also be spoiled by random hooligans with lists or small debris in the key hole.
    2. Option with a combination lock. You must remember the password, otherwise you will have to look for alternative options for opening the locks.
    3. Bicycle grips. The most reliable model, but has a lot of weight and some limitations. With them, you need to look for a special bike stand, since you cannot attach the bike to the fence. The essence of the system is to tighten the steering wheel and wheels with special key grips.
    4. Wheel stopper. They must be tightened with bolts, nuts and a special wrench. This is more suitable for long-term storage, as the procedure takes a long time each time.

    Each of the above locks, except for the last option, can be opened independently if desired or necessary. The wheel stopper cannot be removed without a key with a hole shape for special bolt heads, you will have to call specialists.

    Autopsy Methods

    You can open any lock from cheaper and simpler models if you know some of the nuances and technologies. You do not need a professional tool for this, you can do with improvised means.

    Padlocks lend themselves to extraneous influence quite easily - they require a master key. A hairpin and a paper clip, a cap from a pen and a wire, even an aluminum can can act in its role. For the smallest simple models, a knife with a thin tip will do.

    To open the lock mechanisms, you need to carry out the following manipulations:

    1. Take two things that will serve as a roll and the master key itself.
    2. Bend their tips to give a larger working volume.
    3. Put the roll like a key to the end and keep it energized, trying to turn it.
    4. With a master key, try to press the pins until the roll turns.

    Combination locks are considered more complex, but in fact they have a small secret. Cheap and simple models of this type quietly click when the correct number is set. In fact, experienced burglars open them in a few minutes, most of which will be needed for disguise.

    Both of the above options are usually complemented by a soft braided cable or chain. If there is no special need to save the castle, then you can simply have a bite to eat with special pieces or cut them with a grinder.

    You will have to suffer with the grips, because usually there is a built-in lock. However, it is opened by the same method as the hinged one. The only problem is that it is usually located in the most inconvenient place for unauthorized entry. A bicycle with grips or stoppers should only be left in special parking lots or under supervision, because it is very easy to throw them into a truck and take them away.

    Attempts to open the lock yourself will be successful only with budget models, more expensive versions require professional intervention. Popular brands usually make their lineups very broad, especially for the price. This allows customers to choose between a cheap option for child protection and a reliable lock for fighting thieves.
