Evolution 1090 steel chain bike lock

$112
Catalog updated 2026-10-21

This security solution features 10 mm six-sided chain links crafted from 3t manganese steel. The three-foot length provides sufficient reach for securing a variety of bicycle frames or e-bikes to fixed posts. A durable nylon cover protects the finish of the bike while ensuring the chain remains flexible during use in different environments.

The integrated Evolution series head eliminates the need for a separate padlock, streamlining the locking process. It utilizes a high-security disc-style cylinder that is resistant to picking and drilling attempts. The hardened deadbolt design offers additional protection against twist attacks, making it a formidable deterrent for potential thieves in urban settings.

Designed for convenience, the lock includes three stainless steel keys, one of which features a high-intensity LED bulb for easier operation in low-light conditions. The weather-resistant construction ensures the internal mechanisms remain functional throughout various seasons. This model balances weight and security, making it a practical choice for commuters who require reliable daily protection.
