Bike locks

There are several systems available, with different designs and technology, and here, we look at the most popular. The materials used for their construction is clearly an important factor, as is the thickness of the cables, chains and tubes.

The most advanced technological solutions even have tracking and alarm systems to help you recover your precious machine.

There is no lock that is 100% unbreakable, but the way the locking mechanism is constructed (which is the most vulnerable part of the device) can make a huge difference to the level of security a lock offers.

1. U-locks for Bicycles

   The U-lock is one of the most secure systems, providing it is made of quality materials and tubing. It offers a very high level of protection, but the size and weight are a disadvantage. This type of lock is therefore not suitable for sports bikes, such as those used for touring and mountain biking.

   Some locks in this category can be considered as almost totally foolproof, such as the Kryptonite New York U-Lock M18-WL. This 16 mm bar lock offers the highest level of security for urban use. The lock has patented systems to protect against various possible threats.

2. Cable and Chain Locks for Bicycles

   Cable locks sometimes have reinforced jointed steel sleeves, to protect the inner cable and these are are similar to those used for securing motorbikes. Bicycle chain locks have some similarities, but are adapted to the particular needs of cyclists. To protect the relative fragility of bicycles, the cables are sheathed in soft plastic or vinyl.

   An important advantage of these locks is that they are relatively flexible and more versatile than the rigid U-locks.

3. Folding Locks

   Another interesting anti-theft system is the folding bicycle lock, made of steel bars, with several hinged points. They are generally compact in size and provide flexibility at a low weight. A good example is the Abus Bordo Granit X-Plus 6500/110 SH, whichcan be carried on the bike, in a backpack or even in some cycling pant pockets.

   Folding locks are available with either medium or high levels of protection and in different lengths.

4. Spiral Anti-theft Cable for Bicycles

   This type of lock is ideal for locking several parts or accessories of the bicycle together. They consist of a spiral cable, coated to protect the frame. Available with a multi-digit combination opening system or a conventional key and even without a lock, so that you can use your own locking system.

   Spiral cables do not offer the highest level of protection and depending on the thickness of the inner steel cable, they can be cut with tools.

5. Anti-theft Devices Integrated in the Bicycle

   These are systems that normally immobilise the rear wheel to make it difficult to move the bicycle. They can be useful for a quick stop, but they should not be considered as a secure anti-theft system.

6. Anti-theft Accessories for Storerooms and Other Facilities

   Abus sells systems for anchoring bicycles to the walls or floors of garages and storage rooms. They are fitted with special high-strength anti-theft screws that make it difficult to remove the equipment from the premises.

It is important to choose a good location for locking your bike and it is always recommendable to do so in an area with a certain amount of pedestrian traffic as this detersthefts. There is no point in using a great lock if you choose a poor location.

It is always good practice to chain both the bicycle frame and a wheel. If you have more than one lock or chain, secure the other wheel to the frame as well.

Never put the lock on just a wheel, as this leaves the most valuable part of the bicycle completely unprotected. And if you just put a lock on the frame, the wheels will be unprotected, which is why it is best to secure a wheel or both wheels to the frame.

If you put a lock on several bicycles, it is best to chain them all together, as this complicates theft, due to the weight and the difficulty of handling a group of bikes.

And the lock should not be in contact with the ground, as this can make it easier to break.
