I had three stolen from my garage a few years ago. I recovered one, but have never see the other two since.
Kind of a funny story. One of the guys at my LBS saw a kid riding around on My Bianchi DISS. At first, he just thought it was odd that a kid was riding a $1000.00 singlespeed with eggbeaters. I'm 6' tall and apparently the kid didn't even lower the saddle.
After a second look, he recognized the bike as one of mine that was stolen and he called the cops. They busted the kid, but he claimed that he found it laying on the side of the road. He was a minor, so I didn't get a chance to talk to him. I was mostly interested in recovering the other two bikes. The cops believed his story, so I did not press charges.
Sorry to hear about your ride. That sucks! Bike thieves should be treated like horse thieves were in the old west.
If you have your serial number you can register your stolen bike with the
National Bike Registry for 99 cents. The registration lasts for 6 months. If your bike is recovered anywhere in the US, law enforcement has access to their data base to identify the owner.
