5 Digit Combination Heavy Duty Anti Theft Bicycle Chain Lock

$9.99

Catalog updated 2026-10-22

This bicycle chain lock uses a five digit resettable combination dial instead of a key, so riders can set and change their own code. The locking mechanism is built into a compact head that accepts the chain ends, making it a self-contained option for cyclists who prefer not to carry a key on every trip.

The chain is available in several lengths and thicknesses, ranging from shorter runs suited to securing a frame and wheel to longer spans for gates, fences, and door handles. Thicker chain links add weight and bulk, while slimmer versions keep the lock easier to coil and transport in a bag or around a seat post.

Because the combination is user-set, the lock works well for shared use, such as a household gate or a scooter kept outside a shop. The chain construction is intended for everyday anti-theft duty, and the resettable dial means no spare keys are needed if the code is forgotten or changed.
