Would i notice any diffrence in acceleration or speed if i only installed a new controller?
@SamuelS not really, your acceleration and speed is based on your controller, motor and battery combination. Your motor will probably accept a bit more so that’s fine but your limit is your battery BMS limit. Your amp draw is what gives you your acceleration, if you can up your battery current as well as change your controller you can certainly squeeze some more out of it.
Look at my topic, i can only say go for it, the bike is so much more fun to drive. I am not done yet but my drive tonight was perfect.
