The standard anti-theft U: It is the necessary protection to be equipped with minimal protection. The anti-theft bolts U are now the best-rated locks according to the numerous tests. However, if the handle is too short, the U-lock can be complicated to hang on certain street furniture.

There are also code U-shaped bicycle lock locks that lock using a customizable number combination. A real plus for cyclists who tend to lose their keys.

The folding U-lock: This anti-theft has a form of the meter of a joiner. With its articulations, it is simpler to fix the bike to the street furniture with this type of anti-theft. This kind of anti-theft was introduced a few years ago with an emblematic model “the Bordo” from Abus. Today the brand has declined this anti-theft in versions with codes, light, longer or colored.

The Kryptonite brand also offers a foldable U-shaped bicycle lock. Very practical, it is 100 cm long and folds quickly to transport easily by bike without cluttering the cyclist.

The frame anti-theft system

Indeed, installed on the bicycle, it is enough of a simple keystroke so that the rear wheel is blocked. Some models even allow combining this anti-theft with a chain or an additional cable to increase the safety of the bike and to put off the most motivated thieves!


The chains are an excellent protection for bicycles and allow fixing to the street furniture relatively straightforward and practical. However, for an excellent protection, it is necessary to privilege a chain with links of 8 mm minimum. The ideal is to couple the chain to an anti-theft U. The chain will secure the wheels and the U the frame of the bike.

Locks for accessories

In addition to bicycle theft, the bike’s equipment is also vulnerable. It is, therefore, best to protect it too. Systems that replace the axles of the wheels and the axis of the seat clamp make it possible to secure your bike more. The best-known models are the Tranz-x anti-theft axles that secure your wheels and saddle with a unique key, and the Lock’N Roll axes, which, by a level system, only open when the bike is turned over.

They usually have a sound volume of 100 dB to 120 DB or the size of a hammer or battery. The alarm allows you to surprise the thief if the thief tries to shear the cable or violate the casing.
