Any documentation on the bikes including pictures will help when talking to the police. My bike was stolen in Feb. In Mar I found it on Craigslist. The thing is, "that looks like my bike" isn't good enough. I ended up calling the seller and arranging a meeting. At the meeting I was able to positively ID my bike from the Trek ID number. I told the seller I would call him back later if I didn't find anything else then called the police. They had me set up another meeting later that day and met with him and ID'd the bike from the documentation I gave them. I'm telling you this so you know what to expect. As said above watch Craigslist and ebay. Good luck.
