Fair enough, with regards to parts, many on this forum recommend calling ThorUSA (online dealer based in California). If you wait until you get to NYC, there are a lot of bike shops that service Dahons, although Franks bikes shop might be the best since there were probably the only one in business in 1986. The place is a bit of a mess and it honestly wouldn’t surprise me if they had a bike similiar to yours buried somewhere. Spokesmen cycles has several locations and also services Dahons. I use them as I live near one and found the are usually pretty good, with reasonable prices for the nieborhood.
