I hear that bufang motors are able to be customised but to what level. For example on my 750watt bufang motor it does take quite a while for the bike to get going unlike a integrated bike that presumably has more torque at the start. Have rang an ebike conversion shop regards tuning my motor to have a bit more torque at the start and they say the only thing they can do is reduce the performance of the bike to increase the longeviety of the motor. Are bufang motors actually able to be more customised?
