A guy found the bike 20 miles from where it was stolen, emailed into this website, confirmed the serial number and I met him. Gave him a $50 reward. Thank you for hosting this incredible service Bike Index!!!

My girlfriend found the thief/seller on Craigslist and arranged to meet him to buy the bike for $200. I used the Bike Index to warn local shops that the thief was trying to sell it locally, so he was forced to sell it back to us via the internet at a very reduced price.

King County Deputy Robert Nix recovered it the same evening and put it into evident storage, found my Bike Index listing. Kudos to the fantastic police work and the outstanding service this website has become! Donations are well deserved to keep this website going.

Not to be over exuberant or anything, but I'm ecstatic. A guy named Sam called last night, said he was working with the police and he was almost certain this was my bike. I took the bus down to the Seattle Police Southwest Precinct this afternoon, and low and behold, there it was. Almost 2 months later. Thank you so much, Bike Index.
