I was considering trading my OCC schwinn stingray motor bike with someone who had a Skyhawk/cruiser build I had found on Craigslist. After looking around on the forums and closely looking at the photos of his bike I came to the conclusion that his cruiser was only equipped with a coaster brake. It might have been removed, and at the very least compromised, by the bicycle mechanics who he paid (a lot) to assemble it. I emailed him to let him know about the safety issue of his bike and advised him to either invest more and have rim or disc brakes installed or at the very least disclose the facts to any potential buyers. His original ad is still posted on Craigslist and doesn't say anything about this issue. I feel obligated to flag his post or at least post an RE: letting people know what they might be purchasing. Any advice?
