Just bought a second hand Dahon Helios P8 (http://www.bikefold.com/dahon_helio_p8_bike.htm) last night. Paid CAD $240 which I thought was a fair. Overall, very impressed with the components (Truvativ, Kinetix wheels, Schwalbe Marathons, Ritchey bar, Biologic grips & seat, SRAM 3.0 Comp shifters. Planet Bike rear fender. The bike accelerates very well and its handling is just superb. I adapted to the bike right away and it felt completely natural.

However, the handlebar post is loose!! What is the matter with Dahon? They have known about this issue a long time. Being the largest manufacturer of folders, it is not difficult for them to redesign this part and make it work. In all other aspects, I think this Dahon is a fine, fine bike.
