Bike U locks
The must of locks
The U-lock is now the most used by cyclists, since it is the best protection against bike theft. Named like this because of its shape reminiscent of the letter U, it is appreciated for its simplicity and robustness. Some disadvantages, the U is generally a little heavy (1kg) and a little more difficult to set up due to its rigidity (you have to take the helping hand!)
