Kryptonite Messenger Mini Bike U-Lock with Wheel Extender

The Wheel Extender allows you to secure your front wheel alongside your frame without needing a second, heavier lock. It effectively increases the locking area, making it easier to capture both the wheel and the frame to a bike rack.

Yes, the 11mm hardened steel shackle is designed to resist common theft tools like bolt cutters and leverage attacks. While no lock is impenetrable, this model provides a high level of security suitable for e-bikes and standard bicycles in urban environments.

The main U-lock has an interior locking space of 3.75 inches by 6.5 inches. The included Wheel Extender adds an additional 3.25 inches by 3.75 inches of reach.

If you lose your keys, Kryptonite will ship your first two replacement keys to you for free, anywhere in the world. You simply need to register your key number on the Kryptonite website immediately after purchasing your lock.

This is a reimbursement program where Kryptonite may cover up to $2,500 if your bicycle is stolen due to the opening or breaking of the lock by force. To qualify, you must register your lock on the Kryptonite website within 30 days of purchase.
