This innovative lock is made from multiple hardened steel cores for maximum protection. It mounts right at the handlebar and locks both throttle grip and brake lever making it impossible to roll your bike. Included are 2 keys and rubber dampers to ensure a snug fit around every size of grip. We like this lock because it's super visible to potential thieves, making stealing your bike more difficult than the next. An added bonus and incentive to use it all the time is that the D-Ring of a helmet can be slid over your bike lever allowing it to double as a helmet lock!
