I just purchased a storybike and it is not going to work so must return. It is 20" which does not allow me to put my feet down without being on my toes. Also the thinner tires are not as stable as a little wider. I am 5'4" and 66 yrs. old. What I liked about this ebike is it has hand bars that can be adjusted like a cruiser so you can sit up right. I am now looking for your help as there are so many ebikes out there. My needs and ideals are a wider tire for stability, a step thru, lightest weight as possible, 16" height ideal so I can put feet down, handle bars that allow one to sit up straight and a full throttle for the big hills. Am I asking for an ebike that does not exist?
