I looked into craigslist, and it seems that they want to function as a localized service. There is no free way of posting over multiple areas, although there are services that will do it for you. Craigslist uses your IP address to determine your location, so if you spoof your IP, you could post in another region. Still, it would be a lot of work to do a lot of cities. I'll try some tests to see how far away I can post. I might be able to get something into the Los Angeles area. We should consider what would happen next if someone were to respond. A lot of people are not going to be able to pack a bike for shipping, or even strip off the parts you want. The less convenient it is to get it to you, the more you are going to have to pay. How much is it going to be worth to you?
