The Lock works fine, but it's so short that it's difficult sometimes to get it around both the bicycle and the object I am trying to lock it to. A few more inches would make a big difference.

I got the size medium for my daughter’s beach cruiser and she has had no issues securing it to a bike rack. The keys go in smoothly and are easy to use. The mounting bracket is all rubber with a separate rubber lining on the inside so that it doesn’t scratch or slide around on your bike. The bracket feels a little flimsy to me especially when I was screwing it onto the bike. I thought the screws were going to strip it. But they didn’t and the bike lock is mounted on to the bike just good enough, in my opinion. You just have to be gentle when mounting it onto the bracket which is a little hard since the lock itself is pretty heavy! But there hasn’t been an issue when riding the bike with the lock mounted on it. It is not very cumbersome where it gets in the way while pedaling. We haven’t used to cord that comes with it since the Medium sized lock is big enough to comfortably secure the bike to the rack. Overall, we are happy with it for the price I paid for it.

I liked this lock. It was nice. I didn't like the mounting system, and the cord that was included was a little too short to lock both the wheels up so that they didn't get stolen (I live in a bad area).

Nice big lock that will fit your e-bike frame. Plus good long cable, long enough for both wheels don’t have to take the front wheel off . It’s heavy but it’s a strong lock
