I’m currently planning to build an electric motorcycle for commute purposes. I’m thinking of a 48v 80ah LiFePO4 battery pack for the motorycle, but still abit torn between what drivetrain i should use-Living in Vietnam, the traffic is quite busy and there will certainly be alot of stops during my commute. I’m a bit torn between the 17inch qs motor’s hub motor and the 5kw golden motor. I don’t know what would be my donor bike yet, but it would very likely to be a 150cc motorcycle. In that case would the hub motor setup be more beneficial, taking up less frame space? I’m worried that a chain drive setup would locate the central of gravity upward, which may affect handling characteristic of the motorcycle. I really need help and advices since this is my very first ev project.
