I have a Dahon III folder that I bought on E-Bay (I have no idea what this bikes provenance is). The rear fender is broken at the frame mount (old plastic, I probably shouldn't have used the fender as an occasional "third leg" when folded). I don't really use it anymore and want to sell the bike to a friend who lives in Philly, but I don't want to sell her a broken bike.
I've done some Google searching (and searching on here), but the only replacement fender that I've found was this expired e-bay listing: Rear Fender Mud Guard for Dahon Classic III Bike Bicycle | eBay
I know nothing about the vintage folding scene. Does anyone here have any suggestions on where I might find a community of folks who might be able to sell me a replacement, or give suggestions on how to hack a fix?
