I took a second look, and I gotta ask, what engine is that? And how doe's your hand brakes work with speed? I only ask because my 1st build was a mountain bike with hand brakes, and it did'nt stop well at all! I tried different pads,and everything else I could try, but I ended up going to beach cruisers with coaster brakes, and eventually with front disk also! I must say though, Thats awesome!!!!!
