The chain lock is one of the best ways to secure your bicycle. The heavier the chain lock is or looks, the less likely it is that a potential thief will try to pick your lock. Despite the weight that such a chain lock brings with it, it is still practical because the movable chain links mean that it can be attached to almost any parking space. Whether short chain locks for the thin racing bike frame or longer ones for fat bikes. Due to the different lengths available, everyone can find something for his needs. Chain locks can be opened either with the matching keys or with your individually defined numerical code.
