As much as we'd love to have a well trained, thief deterring German shepherd guarding our bike at all times, the logistics of such an operation are prohibitive, to say the least. Get easily portable and fur free bike protection with the OnGuard K9 Folding Lock. Claimed to be nearly as secure as a U lock and boasting versatility akin to a cable lock, this lock is constructed from a series of hardened steel plates that fold together on hinges for easy storage on a bottle cage mount or strapped against a tube when not in use. The K9 Folding Lock includes OnGuard's pick, pull, and drill proof cylinder with a sliding keyhole cover for an extra dose of thief deterring security. It comes packaged with two keys and a mounting bracket.
