U-Locks

One of the most secure locks to protect your bike against theft is the U-lock. A shackle lock for your bike consists of a U-shaped shackle made of hardened steel and a rod-shaped locking mechanism. The disadvantage of the U-lock is that it is relatively heavy and large. This type of lock also has a limited size and is not flexible. On the other hand, your bike is very well protected against theft!
