Keyed black steel chain lock for mountain bikes

Updated 2026-09-05

This durable chain lock is designed to provide essential security for mountain and road bikes. The 2.62 ft length is optimized for portability while still providing enough reach to secure the frame to a post. Its heavy-duty steel construction offers a solid physical barrier against common theft methods used in urban settings.

The lock utilizes a traditional keyed mechanism, and it comes with two keys to ensure you have a spare available. This straightforward locking system is reliable and easy to use, providing a physical sense of security that many cyclists prefer. The internal cylinder is designed to resist picking and drilling attempts.

A protective black fabric sleeve covers the entire length of the chain, preventing the metal links from coming into direct contact with your bicycle. This helps maintain the aesthetic of your bike by preventing scratches and dings. The compact size allows it to be easily coiled and stored during your ride.
