Common Circuit Problems Checking 

5. Whole bike without assistance: Situation one 

if the bike with throttle

                                                                                                                                                                              

The Display can be lighted up, the motor works if we push throttle(if the bike has) or use 6KM/H pushing speed function, while there is no 

assistance power when we cranking; 

Solutions

                                                                                                                                                                                                                            

1.Check whether the sensor works normally or abnormally.                                                                                                                                                                                

Please check the space between Magnets disc and sensor is 2-3mm or not.                                                                                                                                                                             

Please check if the sensor indicating light is flashing or not and when you crank, the light is flashing or not.                                                                                                                  

2.Check whether the contact pin between the controller and the sensor is interrupt or inserted crookedly;                                                             

3.Change a new controller to test.                                                                                                                                                                                                                                                                                                                                                   

6. Whole bike without assistance: Situation two                                                                                                                                                                     
The display can be lighted up, the motor doesn’t work no matter we push the throttle ( if the bike has), crank or use 6km/h pushing speed. 

Solutions

                                                                                                                                                                                                                            

1.Check whether the controller and the connecting line is loose or damaged, or whether the contact pin is inserted crookedly;                                                           

2.Check whether motor connector is loose or damaged, or whether the contact pin is inserted crookedly;                                                           

3.Check whether the sensor works normally or abnormally.                                                                                                                                                                         

Please check the space between Magnets disc and sensor is 2-3mm or not.                                                                                                                                                                           

Please check if the sensor indicating light is flashing or not and when you crank, the light is flashing or not.                                                             

4.Change a new motor to check if bike can work or not;                                                                                                                                                                     

5.Change a new controller to check if bike can work or not ;                                                                                                                                                                      

6.If there is a motor patch cord , please check the patch cord work normally or not;
