Nothing hurts more than a stolen bike, and German startup MyBikeNumber exists to make your wheels a little safer. It’s a free online service that lets you register your cycle and its parts in a worldwide database. After signing up, users can quickly print custom QR Codes for different components, and add photos of their beloved bicycle to a personalized profile. Cyclists can even search the site to confirm that the sketchy suspension fork they’ve been eying on Craigslist wasn’t yoinked from someone else’s ride. It’s nice to know someone’s looking out for the critical mass.
