Five digit combination heavy duty chain

Updated 2026-09-05

This heavy-duty chain lock eliminates the need for keys by utilizing a secure 5-digit combination mechanism. With 100,000 possible combinations, it offers a high level of security against code-breaking while providing the convenience of keyless entry. The 3.28 foot length is perfect for securing a single bicycle or scooter to a fixed object.

The chain links are encased in a durable fabric sleeve that protects your bike's finish from scratches and reduces noise during transport. The internal steel links are designed to resist cutting and sawing, making it a robust deterrent for opportunistic thieves. It is particularly well-suited for students and commuters who want to travel light.

The flexible nature of the chain allows it to be easily coiled and stored in a bag or wrapped around a seat post. This lock is versatile enough for use on gates, fences, and outdoor equipment in addition to bicycles. The weather-resistant dials ensure that the combination remains easy to turn even in rain or cold conditions.
