High security u-lock with extension cable

Updated 2026-09-05

This high-security set combines a robust U-lock with a four-foot extension cable for comprehensive bicycle protection. The U-lock is crafted from hardened steel to resist prying and cutting, while the additional cable allows you to secure secondary components like the front wheel or accessories that the main lock cannot reach.

The locking mechanism features a drill-resistant cylinder, adding an extra layer of defense against sophisticated theft attempts. Two keys are included, providing a backup for the owner. This dual-locking system is ideal for high-traffic urban environments where maximum security is required for both the frame and removable parts.

Designed for durability, the 12mm steel components are built to withstand physical attacks. The compact size of the U-lock makes it easy to carry on a frame mount or in a backpack, while the flexible cable can be coiled tightly when not in use. It is a reliable choice for riders seeking peace of mind.
