Overview
Locking an e-bike or scooter to a fixed post is the job of this thick shackle U-lock, which uses a double deadbolt design and a vinyl coated pick-resistant disc cylinder. A bracket carries it on the frame, and three keys come with it.
The reason to buy is protection aimed at long stops: the maker rates it suitable for all day and overnight on campuses, suburbs and rural areas. The limit is the heft and the missing interior size, plus an app control row that is plainly wrong.
Who it's for
Riders of valuable or heavy bikes who need a stout lock for a campus rack or a city post. Casual cyclists who value low carry weight above all would be better with a smaller lock.
Pros and cons
- Thick hardened shackle
- High maker security rating
- Three keys included
- Frame mount bracket
- Heavy to carry
- Interior opening not listed
- App control row looks wrong
Performance notes
A thicker shackle and a double deadbolt make bolt cutters and leverage attacks harder, and the disc cylinder is protected from picking and drilling. Security still rests on what the lock is fixed to, since a weak post defeats a strong lock.
