Bike Index membership
Keep Bike Index free for every rider
Membership is a monthly donation to Bike Index. It pays for the registry and the stolen bike alerts that get bikes home, and it funds the new tools we build next. Registering a bike and reporting a theft will always be free. Members are the reason we can promise that.
Memberships and one-time donations are tax-deductible in the US. Bike Index is a 501(c)(3) nonprofit, EIN 81-4296194.

The registry, open to everyone
Registration and search
Registering, searching, and checking a used bike cost nothing, for riders, shops, and police. We don't sell rider data.
Stolen bike alerts
Theft reports go out to shops, police departments, campuses, and riders near where the bike was taken.
Partners and recoveries
Onboarding new shops, departments, and cities, and helping police match recovered bikes to their owners.

Guy who bought it from the thief saw my ad on Craigslist and reached out. Was returned the day after it was taken.

The team found it at the park and contacted me to pick it up!

A man called me saying he bought the bike, and was going to register it on Bike Index, then he found that it was posted stolen, so we met up and I got it back. He didn’t ask for anything, but I payed him what he paid for it, which wasn’t too much luckily. When someone is so kind and does the right thing, it should be rewarded. I’m very happy I got my bike back!
