Major giving
Larger gifts move whole cities onto the registry
Gifts at this level go toward partner onboarding, cross-border theft investigations, and the engineering behind promoted alerts.
Other ways to give at this level
- Donor-advised fund grants — we can send our EIN and grant details.
- Gifts of stock or crypto, which avoid capital gains on appreciated assets.
- Employer matching — many employers will match a donation at no extra cost to you.
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.

Tracked it with an AirTag to place it was on back porch - took it back and then notified local PD.

Filed a police report, made a ton of facebook posts, registered the bike here. Apparently someone who saw a post, saw someone riding my bike Friday night and called the police. the police followed the man to his house where there were multiple bikes being stored and upon checking the serial number, confirmed the bike was stolen and belonged to me. Its been sitting in evidence since Saturday.

A million bikes are registered. Not one owner paid to be there.
Keep it free for the next million.
