Description

When you need solid everyday bike security without carrying oversized hardware, the Trelock U4 Mini ZB 401 hits the sweet spot.

The 14 mm hardened steel shackle delivers strong resistance against cutting attempts, while the drill-protected cylinder adds an extra layer of security where it matters most. With a security rating of 12/18 on the Trelock scale, this U-lock is a dependable choice for daily use in urban environments and medium-risk areas.

Its compact internal dimensions of 83 x 152 mm make it easy to secure your bike frame to racks, railings or other fixed objects, while keeping the lock practical to transport. A sliding dust cover protects the locking mechanism from dirt and moisture, helping maintain smooth operation over time.

The rubber coating prevents scratches on your bike frame, and the included ZB 401 mounting bracket allows convenient transport directly on your bike. Keys are included in the set, and additional keys can be ordered via the official TRELOCK website if needed.

Simple, solid and purpose-built – this is everyday security you can trust.
