Denver commuter,,, Im gathering parts for my fat tyre bike . So far ive got the motor , battery , throttle , and thought about a standard cheapie controller , but have since bought a sine wave 36v & 48v adaptable , up to 500w controller . This will go with my 48v battery and the 36v 400w motor . I paid aud$50 which I think isn't too bad . My goal is I guess you could say for the area I live which is flat; get more speed , not torque , and distance . My other bike "which is considerably lighter" has a 200w motor and using the same battery gives me 26mph , the fatty weighs in at around 18kgs so im hoping the 400w motor will compensate for the extra weight . and give me the same speed and distance "30miles" thereabouts on 1 charge .
