Help us fight bicycle theft—Index your stolen bike.

The Bike Index makes stolen bikes harder to sell and easier to recover by making it possible to find and contact stolen bike owners.

The process is simple, secure, and free. Register your stolen bike.

We've registered 222,497 bikes and recovered 5,415 stolen bikes.

So far we have 625 partner bike shops, police departments, and bike advocacy organizations.
