New York 1210 keyed chain lock

Updated 2026-09-05

This 3.25 ft chain lock is engineered for high-risk urban areas where maximum security is required. The 12mm six-sided chain links are made from hardened manganese steel, creating a formidable barrier against cutting tools. The length is perfectly balanced for securing a single bike to a variety of urban fixtures.

The system includes a disc-style lock with a 14mm hardened steel shackle and a double deadbolt design. This configuration ensures that the lock remains secure even if one side of the shackle is cut. The cylinder is highly resistant to picking and drilling, providing peace of mind for city riders.

A protective nylon sleeve covers the chain to prevent scratches on the bike frame and to protect the metal from corrosion. The lock comes with three keys, including one with a built-in light. This heavy-duty security tool is designed to withstand the toughest conditions and the most determined theft attempts.
