Crank Arms Lock / Bicycle equipment

Crank Arms Lock

Crank Arms Lock is unlike anything seen before. It redefines what we come to expect from the bicycle locks – no heavy iron bars or messy steel cables, no weight and no storage issues. Just one simple and perfectly integrated solution to bicycle locking.The lock is fully integrated into the bicycle crank shaft. When locked, it disables the crank assembly by internal bolt action. Additionally, it disables the rear wheel by folding and locking one pedal in the reverse position, wedged inside the rear wheel wirework. This dual action provides deterring effect for the bicycle thief rendering the bicycle useless in case lock is broken.
