Where the money goes

Registration stays free

Servers, support, and the search tools that shops and police use at no charge. No paywall, no tiers, no selling rider data.

Alerts that reach people

The stolen bike alert system and the promoted alerts that push a listing into feeds around the theft.

Partners and investigations

Onboarding new shops, departments, and cities, and the long-running theft-ring investigations that come out of the registry data.

Features for bike owners

The marketplace, where a listing starts from a bike already in the registry — built to make selling a stolen bike harder. More owner tools are on the way.

In their owners' words

Every recovery is reported by the person who got their bike back.

1.8 million bikes are registered. Not one owner paid to be there.

Keep it free for the next million.
