Started in 1997, Pinhead is now the industry leader in bicycle component locks. Pinhead locks are used by cyclists, rental fleets, and bike share programs in more than 20 countries to protect bicycles and major bicycle parts. All components are precision molded and forged from corrosion-resistant CrMo steel and aircraft aluminum alloys. Once installed, the locks remain permanently on the bicycle, even when you ride. When you need to remove your wheels for servicing, or adjust your saddle height, your Pinhead key lets you do this quickly and easily. Their mission is to improve cycling security and safety with high-quality locks that protect the bike and provide a safer ride.
