Long Shackle U-Lock with Mounting Bracket

Updated 2026-09-05

Featuring an extended shackle length, this U-lock is specifically designed to accommodate the thicker frames found on e-bikes and scooters. The 12.7mm hardened steel construction provides a formidable barrier that has earned a Sold Secure Gold rating. It comes with a dedicated mounting bracket for convenient on-frame storage while riding.

The long shackle design offers greater flexibility when reaching for awkward anchor points or securing multiple parts of the bike at once. Its high-security cylinder is protected against picking and drilling, ensuring the locking mechanism remains functional and secure. The keyed entry system is smooth and designed for heavy daily rotation.

This model is an excellent choice for riders who prioritize versatility without sacrificing strength. The inclusion of the bracket eliminates the need for a backpack, as the lock stays securely attached to the frame. Its robust build quality makes it suitable for high-risk urban environments where professional theft is a concern.
