A quality bike lock is an important purchase in protecting your bicycle investment. When commuting by bike, your bicycle will most likely be locked up in the same area five days out of the week. Because of this, a would be bike thief may see your bike on a daily basis. You want to be sure to have a lock that is very secure and not easy to break. To achieve the best security, we recommend U-Locks or rugged chain locks. A cable lock can be cut and your bike stolen, so we only recommend cable locks for light use, such as going to the coffee shop or for locking your bike up in low crime risk areas.
