Introduction
Bicycle theft is a scourge. In France, over 400,000 bicycles are stolen each year. For a road bike costing €3,000-€10,000, a good anti-theft device is essential. Here is a comparison of the best ones in 2025.
Types of Locks
U-lock
The most secure. Difficult to cut, compact, lightweight. The benchmark for valuable bikes.
Chain lock
Flexible, allows the bike to be attached to supports of various shapes. Heavier than a U-lock.
Cable lock
Lightweight and flexible, but easily cut. To be used only as a complement to a U-lock.
