I’ve used this U-lock daily for months on my bike rides around the city. It’s super tough and the silicone hasn’t scratched my bike once. I also love how easy it is to clip on and off my bike. I feel really safe knowing my bike is well protected.

I’ve been using this lock for two months, and it hasn’t scratched my bike once! Love how it mounts on my frame easily.

This is a mini lock and so requires a bit of positioning to find the right orientation to include the bike frame and whatever you’re locking to. Otherwise, it’s solid and easy to carry around
