(which with assistance sensor and Magnetic encoder on pedal axis)↔? <br />pulse signal of different frequency is sent by pedaling harder or slower↔? the controller push motor turing<br />5.Led meter-has function bellow: indicate battery level↔? output power↔? speed↔? assistance gear adjust and indicate↔? singe range↔? cruise↔? <br />failure↔? historical range↔? running time↔? wheel rotating speed&amp;hellip;<br />6.Self learning- connect power cable↔? motor phase wire↔? hall wire↔? main switch wire↔? handle bar wire↔? learning wire↔? <br />switch on power and bike lock↔? the motor will start to work. If the turning direction is right↔? please cut off learning wire. <br />The learning is finished. If direction is opposite↔? plea
