Bike Chain Locks

Tough enough for high-crime areas, bike chain locks use a specially designed chain link that resists hacksaws or chisels and makes the chain tough to break. Proper lockup is crucial to deterring theft, and a chain lock is the best option for maximum security for many riders. Protect your bike this season with a new bike lock.
