Staff Favorite. Serfas' unique steel-plated folding lock design rolls up to a compact, hockey puck size and stores securely on your bike with its included frame mounted bracket.
Made of 3mm hardened steel plate with stainless steel rivets. Nowhere as strong as a good u-lock but a stronger theft deterrent than any cable lock or thin chain lock.
So small and easy to carry on the bike, perfect for kids bikes and small frame adult bikes but open to the size of a standard U-lock when unfolded.
Includes frame mounting bracket and 2 keys. Free installation when purchased in-store.Lifetime warranty.
