A heavy U-lock with a flexible cable that lets a rider secure wheels or a seat as well as the frame. It weighs about as much as a small dumbbell, so it is not for rides where weight counts.

Overview
Locking a bike to a rack with this U-lock uses a four-sided mechanism to resist cutting, prying and twisting. A vinyl-coated cable adds a second loop for wheels or accessories, and a bracket carries the lock on the frame.
The shackle and cable together give a double-locking system for bikes, e-bikes and scooters, and the rubber sleeves protect frames from scratches. Weight and the size of the shackle opening limit where it can be used.
Who it's for
City riders and e-bike owners who lock up for hours will use the added cable. Weight-conscious riders and anyone locking thick poles should check the shackle size first.
Pros and cons
- Quad lock on four sides
- Cable for wheels and seat
- Rubber-coated sleeves protect paint
- Five keys with an LED key
- Heavy to carry
- Shackle opening limits what it can lock
- Control method listed as app is unclear
Performance notes
A thick hardened shackle resists cutting, and the four-side lock resists prying and twisting at the crossbar. The cable is thinner and mostly deters opportunistic theft, so the U-lock does the main work.
