Steel U-lock with four foot extension cable

Updated 2026-09-05

This security set combines a classic steel U-lock with a flexible 4 foot extension cable for comprehensive bicycle protection. The U-lock serves as the primary anchor for the frame, while the 10mm cable allows users to secure wheels and accessories simultaneously. This dual-layer approach significantly increases the time and effort required for unauthorized removal.

The steel shackle is treated with a vinyl coating to protect the bicycle frame from chips and scratches during transport. Included with the set is a convenient mounting bracket that attaches directly to the bike frame, ensuring the lock is always accessible. This integrated storage solution prevents the need for carrying a heavy lock in a backpack.

Engineered for outdoor use, the keyed mechanism is designed to resist picking and drilling attempts. The black finish provides a low-profile aesthetic that blends well with most modern bicycle designs. By utilizing both the rigid shackle and the flexible cable, cyclists can achieve a high level of security in various urban parking scenarios.
