Craigslist is great. However, it also serves as a giant flea market which makes the movement of stolen bicycles easier. It also allows the recovery of stolen goods as the listings are searchable and viewable by anyone. Just take a look at this example of a stolen Guru Tri Bike that was recovered by browsing Craigslist.
Here's my plan: make Craigslist the ultimate stolen bike recovery tool, or at least take it out of the thieves toolbox by requiring posters to include a picture and/or the serial number of the bike. Here's the message I just sent to Craigslist through their feedback form:
Craigslist is a great tool for selling bicycles and bike parts, but can also be used by thieves to sell stolen equipment. Why not make this impossible (or at least harder to do)? Can you make it a requirement that each bicycle ad must contain a picture of the product (making it easier to identify stolen goods) or require that each bike ad post the serial number of the bike (discouraging thieves)? This last option would dovetail nicely with the Stolen Bicycle Registry website here: http://www.stolenbicycleregistry.com/Thanks!
Think about it, maybe send some feedback of your own. Write down the serial numbers of your stuff, register your bike, take photos and save them, engrave your initials on your bottom bracket. Thieves are stupid, exploit them for it. Link to this post, pass it on, be part of the solution!
