(Rated 4.84/5 by 2490 customers)


"I am surprised, usually these locks costs somewhere around $80. Perfectly fits my needs. It is small and fits in my water bottle cage, came with extra keys. Really easy to wind up and lightweight. It fits anywhere and it attaches to your bike and doesn’t get in the way when riding. Definitely getting another one for my e-bike"

" I left during the summer, and someone tried to steal my bike, but the lock withstood the cuts, so I bought another one for my brother. "


Jeff P. 11/02/2021




"I was looking for a lock that would be lighter than a bar lock but provide reasonable security. This one seems to fit the bill perfectly. It is not much bigger than a cigarette pack but the metal bars are decently thick, would probably require a very large bolt cutter or a grinder to get through."


Stephen V 01/27/2022




" Someone tried to steal my bike yesterday and the chain was all beat up. They tried to break it open but were unsuccessful thankfully. However they did enough damage that I decided to buy another one. Great buy and excellent price! "


Myke B. 09/05/2021




"This is the coolest, best bike lock ever. Smart design long enough to connect to bikes together. Has a plastic coating on metal doesn't scratch bikes. "


Greg H. 02/28/2022



"Compact lock, folds smoothly, doesn't rattle, feels well built and decent quality. Lighter weight / duty than some of the longer models that are heavy but similar length."
