The jack shaft looks to be reversible. How does that work. Do you reverse the wheel and move the brake cable? Because the chain from motor would have to stay in place on the one sprocket so the wheel has to be moved 180 degrees. The frame I bought has bars where some shocks could go. i assume some shocks could be added? And this bike looks beefier than most. Are the handle bars 7/8 inch or are they bigger. Thanks for your help. Metty
