A proper folding bike shop should have proper folding bike locks, right? Well, here it is, the Kryptolok 685 folding lock. Designed to expand to 85cm in length to comfortably wrap your wheel, frame and bike rack, and then fold down into a neat little package. The bracket is different for this lock than other Kryptonite U-locks, and it is able to be bolted down onto the bottle cage mounts for a snug fit against the frame.
Kryptonite stands behind its products by providing an Anti-Theft Protection Offer on specific locks and a lifetime warranty. It is a program that reimburses registered customers for a specific monetary amount in the event their bicycle/motorcycle is stolen due to the opening or breaking of the lock by force.
