I just bought this bike on craigslist. The seller said he bought it and used it in Hong Kong. I didn't get a chance to talk to him much about it. Didn't even get a chance to ride it because the tires were flat and he couldn't find a pump and I forgot to bring one with me when I went to buy it. Fortunately it worked out. The tires hold air and the bike rides okay and shifts well.
I am trying to find info about this Dahon Archer bike and I can find some but I not much. I am trying to figure out which parts came standard and which are custom. It's a little harder of a ride than my fatter tire Dahon S7, but it feels lighter and quicker.
Here's a picture: Are these rims standard?
