Like all folding bicycles, Chedech features a one-sized frame. We designed it as a mini-velo, and therefore does not have the size flexibility of full-size  non-folding diamond “triangle” frames. We have designed it so that, the distance between the front wheel and the rear wheel is shorter than standard frames. The weight of the bike rider can be leaning backward when riding uphill and forward for riding downhill — our bike is light, so rider needs to be careful when traveling on steep inclines and declines.
