Well I have had this bike for over 3 years and run a rwd 1500w leaf ebike kit on it 29" it was a walmart Genesis frame and now the thicker gauge spokes on the hub motor some have a small bend in them. This bike only has minimal front suspension and I do run my 18650 battery pack on a rear rack :-( the roads are rough where I live and the bike goes 40 mph when I want. I am also not light at 6'2" 215 lbs. Any suggestions on what you would recommend in a good price range from here? I build everything (battery customize the bike install the kits etc) besides the actual ebike kit which I usually solder the shunt in the controller. Front tire is a stock 29" no bent spoke but not much weight on it unless I am under heavy braking which I upgraded the front discs/pads. I run a partial kevlar tire in the back to increase the strength from the weight.
