Chasing thieves and recovering bikes daily - Donate today! 👇 Bike Index is a non-profit bicycle registration service and stolen bike recovery platform. The service is simple and free to use. You shouldn't have to pay money to protect your bike, so we built Bike Index: a free, universal bicycle registration that will help you get your bike back if its stolen. Anyone and everyone with a bicycle can register their bike on Bike Index, and maintain proof of ownership in case the worst happens. And if it does, you can tap into our global community of cyclists, advocates, and police, city, bike shop, and university partners and leverage them to help you find your stolen ride.
