Riding an electric bike is a funny thing.Sometimes,while riding happily,it stop working and can’t re-start.
\nIf you think your lithium battery<\/strong><\/a> is new,can’t cause this issue.Now you should check controller or bike motor<\/strong><\/a>,how to check?<\/p>\n

If you have volt meter,you could measure as below? So that you can make sure the problem comes from controller or motor
\nIf you can get the same data as below 1, that means controller’s everything is good
\nIf you can’t get the same data as below 2,some hall senor has problem.<\/p>\n

1. Connect all wires,power on.Just disconnect that white big plug with five wires( yellow,blue,green,red,black)
\nThen measure controller’s hall sensor:
\n* The voltage of red and black is about 5.0V
\n* The voltage of yellow and black is about 5.0V
\n* The voltage of blue and black is about 5.0V
\n* The voltage of green and black is about 5.0V<\/p>\n

\n2 Connect all wires,power on.Also,connect that white big plug with five wires( yellow,blue,green,red,black)
\nThen measure motor’s hall sensor:
\n* The voltage of red and black is about 4.5V
\n* The voltage of yellow and black is about 4.5V or 0V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
\n* The voltage of blue and black is about 4.5V or 0v (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
\n* The voltage of green and black is about 0V or 4.5V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)<\/p>\n","protected":false},"excerpt":{"rendered":"
