Q:Received electric bike kit and assembled it according to the instructions,but nothing happens as turn the key and press the throttle. No sound, no movement. Every cable is connected as it should be. Tested the battery with a multimeter,it’s okay.
A:If the battery is no problem.Please test it as below:
1.Disconnect all external wires from brushless controller,except battery power wires and motor wires(blue,yellow and green three thick wires) and hall sensor wires(red,black,blue,yellow and green five thin wires);
2.Make your hub motor wheel in the air;
3.Find a three-pin throttle connector from motor controller,there are red,black and green three wires.Use a wire to jump red and green wires.

If your electric motor and controller are okay,it can run as the fastest speed suddenly.
If not,use your hand to turn your motor,be careful.Motor may run.
If work,problem may come from throttle wire connecting.

Solve:Check throttle connector and wire connecting.

Q:If still can’t work.
A:Should use voltmeter to test motor hall sensor(five wires):
1.The voltage of red and black wires is approximate 4.5V
2.The voltage of blue and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)
3.The voltage of yellow and black wires is approximate 0V or 4.5V(use hand to turn motor,it will change from 0V-4.5V)
4.The voltage of green and black wires is approximate 4.5V or 0V(use hand to turn motor,it will change from 4.5V-0V)

If can’t get voltage from these wires,controller may broken or motor hall sensor is broken.
