you will need to change the BB too. it's not that costly actually. you can get a triple shimano sora for less than $100 with BB. i tried that on my dahon D7 and it's quite tricky i would say. maybe i bought incorrect components. also when you upgrade to a triple some of the gears are not usable because of the cross chain. bike friday is the way to go but really costly or you could check CL once in a while and you might be able to get dahon speed tr (24 speed) or dahon speed pro (27 speed) for a lesser price.
