1000W Electric Brushless DC Motor Kit - 48V 3500rpm Brushless Motor with 20.8A Speed Controller and Throttle Grip Kit for Go Karts E-Bike Electric Throttle Motorcycle Scooter

Note: Due to the motor design having only 2 speed modes, even if the controller has a 3-speed interface, the motor has already reached its maximum speed in the second gear, so the third gear speed and the second speed are the same. The reverse gear has only one speed mode, which is the low-speed mode. before use motor,please make self-leaning test,after test motor can work well.some buyer received package.not make self-leaning test,motor can't work well.so think motor not work.

(1.if motor forward ,Separate the self-learning line. 2.if motor reverse, Separate the self-learning line. let two self-learning line connect together again，if motor forward ,Separate the self-learning line.) Self-learning is to adapt to the supply voltage,adjust the running direction of the motor,simultaneously pairing phase 5.other functions can be connected as needed.
