This is the 250 Series 8FUN LEED front wheel motor hub. Also available in a rear wheel motor model. This planetary-geared BLDC PWM 250w 24v brushless hub motor weighs six pounds and comes with an eight inch three-pin cable attached. To operate this motor you will need a pulse width modulation (PWM) controller to convert the basic DC of a battery to a modulated current (the motor cable contains three power wires). Approximately 200 rpm at a 4-amp load.
