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.

UAPD Investigators were able to locate and arrest the thief. My bike was (luckily) dumped back on campus and I was able to recover it, and justice was served!!

Someone bought my stolen bike in what seemed to him like a sketchy scenario, so he looked up the serial number when he got home to discover that it had indeed been stolen. We met up at a mutually convenient location to hand over the bike.

I made lots of posts about it (Facebook, Nextdoor, & Reddit). I included my Bike Index report in some of the posts. People from Reddit spotted it and that lead to me getting a picture of the thief. I made more posts with that picture. Then someone from the Madison Bike Community page saw my post and got my bike back from the thief.

A friend called me and said that she recovered my bike that someone left it thrown in the parking lot of the lodge. Thank God

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