E.g. the Dahon Boardwalk S1 does not have an adjustable handlepost. Either you like where the bars end up, or you are SOL. If you get a new Dahon Speed D7, you can at least adjust the handlebar height (but not the reach from the saddle to the bars). If you go with a Swift, you can flip and/or swap the stem, and get a little more versatility. If you get a Bike Friday, it's custom so you can get whatever you want.
