Abus Ultra 410K U-Lock

Sold Secure Silver is an independent certification indicating the lock has been tested against common theft tools and techniques. It provides a solid level of security suitable for moderate-risk areas and is often a requirement for many bicycle insurance policies.

The cable is designed to loop through your wheels or accessories and then attach to the U-lock shackle before you lock it. This allows you to secure your quick-release wheels or seat to the frame without needing a second lock.

The included SH 34 bracket is designed to fit standard bicycle frame tube sizes. It mounts securely to the frame, allowing you to carry the lock conveniently while riding without needing a backpack.

The 12mm hardened steel shackle is specifically engineered to resist cutting and twisting attacks. While no lock is entirely impenetrable, this thickness provides a significant deterrent against standard hand-held bolt cutters.

While the Ultra 410K is robust, e-bikes and cargo bikes are high-value targets that often require higher security ratings, such as Sold Secure Gold or Diamond. This lock is best suited for standard commuter bikes in lower-to-moderate risk environments.
