Catalog updated 2026-10-21

This extra-large u-lock is built for maximum security and reach, featuring an 18mm shackle and a 11.5-inch length. The heavy-duty construction is designed to protect high-value electric and folding bikes from sophisticated theft attempts. Its large internal clearance makes it much easier to secure bikes to thick lamp posts or multiple objects.

The inclusion of three keys ensures that you always have a spare available, providing peace of mind for long-term ownership. The locking mechanism is smooth and reliable, designed to resist picking and drilling. The 18mm shackle thickness is a significant deterrent, offering a high level of physical resistance against common hand tools.

For easy transport, the lock comes with a sturdy mounting bracket that attaches to the bicycle frame. This allows the user to carry the substantial lock without the need for a bag. The materials used in construction are chosen for their durability and resistance to corrosion, ensuring the lock remains functional in all weather conditions.
