I'm with inv3ctiv3, but it was too weak for me and I'm 5'3" and 130#. And I haven't had any luck with the motors either (except my son's is good, 1 out of 4 motors). But for how cheap we got 3 of them we were able to build 2 and have many parts. Great kids trikes or starter trikes & my daughters auto-x is the best trail rig ever. I can't see anything being more comfortable and sure footed. All the neigborhood kids come over and ride that 3-wheeler, handles like it's on rails and smooth over bumps. Bottem line: cheap and nice to look at, comfortable.
