I'm looking for a folder to take with me when I travel... and it'll only get ridden when I'm out of state, so portability / storage size are quite important, andI don't want to spend too much. Z-Bikes are flat out the cheapest (and smallest) around (though I can't find much info on them!), and the Yeah! bikes appear very similar to some of the current Dahon designs, for significantly less money (they're manufactured byt a Chinese plant that also makes Dahons, and use licensed Dahon technology). http://www.yeahbikes.com
Anyone have any experience, good or bad, with either bike?
