Overview
Locking a bike to a rack without a key, this U-lock uses a four-digit resettable combination behind a rotating dust cover. The hardened shackle has a BentFoot shape, and the side-mount bracket snaps on for carrying.
Having no key to lose is what a combo lock offers, and anti-rattle bumpers quiet it while riding. The listed rating suits quick stops, with the maker advising longer stays only in quieter areas.
Who it's for
Riders making short stops in town who want a light, key-free lock that carries on the frame. Those locking bikes for long periods in busy cities should look for a higher security rating.
Pros and cons
- Resettable four-digit combination
- Bracket included for carrying
- Limited lifetime warranty
- Moderate security rating only
- Combination can be forgotten
- Overall size not clearly listed
Performance notes
The BentFoot shackle resists bolt cutters and twisting leverage, according to the maker, and the dust cover protects the dials. A combination removes the keyway as a weak spot, though a lock at this rating is meant for short stays.
