Give yourself a step up against the bike thieves out there by bringing along the Abus Booster 6512K Key Cable Lock for your next ride. Its high-quality steel construction holds up against attacks while remaining flexible enough to lock your bike to awkward objects, as the synthetic coating prevents the steel from scratching up your paint job. The automatic cylinder is user-friendly and secure, and Abus even included two keys to keep you covered in the event you lose one.
