Full details
The ABUS Ultimate 420 U-lock is designed for urban cyclists who prioritize a balance between portability and security.

The shackle is made of hardened steel and is 13 mm in diameter.

Is this lock considered secure enough for high-theft areas?

Troubleshooting

Re-tighten the mounting screws and ensure the rubber inserts are properly aligned between the bracket and the frame tubing.

Setup, Compatibility & Care
To install, attach the USH bracket to your bike frame using the provided hardware. Ensure the bracket is tightened securely to prevent shifting during transit. When locking your bike, always aim to fill as much of the interior space of the U-lock as possible to reduce the leverage a thief could apply with tools. Keep the locking cylinder free of debris by occasionally applying a silicone-based lubricant spray. Avoid using oil or heavy grease, as these can attract grit and damage the locking mechanism over time.
