Bike Registration that Works


A man found my bike in an alleyway, looked up the serial number, found my stolen bike listing on and called me to tell me he would like to return my bike. 24 hours later I had my bike back with only some minor damage!

Kelly Bike recovered 04.13.2015

A very kind person contacted me through Bike Index. Someone listed a bike on craigslist matching my bike's description with the same stock photo. I met with the person and had the police nearby— when I identified the bike as mine (with the serial number), they helped me claim it. It had been gone for almost 2 months, I'd accepted it as gone, HUGE thanks!

Atim, the Saint of Oakland, bought it from guy fencing it on San Pablo for $40, hunted me down online, found me on Bike Index, returned the bike, and refused a reward until I forced him to accept one. This all happened about one week after the theft. Atim, if everyone were like you, we'd be living on a higher plane...
