Saw a vintage Dahon in pretty bad shape on ebay. Frame looks like it could be cleaned up, so I put in a pretty lowball bid (considering shipping was free). Received it Friday.
As I sat around looking at all the bikes my kids outgrew, I figure I can convert this into a single speed with coaster brakes. No cables, shifters, etc. A nice and simple beater to chase my kids around the neighborhood with.
I'll keep the 3-speed hub in the parts bin, but the wheels are pretty far gone. The rear fender is broken. That hideously large bar stool for a saddle has to go. Here are the auction pics.
Got the frame cleaned up. All the rust came off with Ed's Red and a wire brush. Had to use a steering wheel puller to pull the cranks (no threads to accept a crank puller). Put in the Sugino crankset with a single 42T sprocket pulled from a Nishiki. Had to use the Nishiki's bottom bracket as well because the Sugino JIS cranks are too big for the original Dahon BB squared taper. Jazzed it up with some gold colored Wellgos. Here it is now:
Rides fairly well. Another one in the collection.
Special mention is needed to acknowledge the donor bike:
