Heavy duty U-lock with steel extension cable

Updated 2026-09-05

This comprehensive security set features a 14mm hardened steel shackle U-lock paired with a 3.77 ft extension cable. This combination allows for versatile locking configurations, enabling users to secure the frame with the U-lock while looping the cable through wheels or accessories. It is an ideal choice for bicycles, motorcycles, and gates.

The U-lock is built to withstand heavy-duty use, featuring a robust combination mechanism that removes the hassle of carrying keys. The included mounting bracket allows for easy attachment to the bike frame, ensuring the heavy-duty components are transported safely. The 14mm thickness provides a high level of resistance against common theft tools.

Whether securing a mountain bike at a trailhead or a motorcycle in a driveway, this dual-layer protection system offers peace of mind. The cable's length is perfectly balanced to provide reach without excessive bulk. The weather-resistant materials ensure the locking mechanism remains functional and smooth even after exposure to the elements.
