Description:<br /> <br />It combines whole wire function for bike, can directly connect brake, <br />rolling handle and function to meter, very simple and concise.<br /><br />Optional function to upgrade meter:<br /><br />Support hibernation state if no action for a certain time<br />Support meter control whole bike electricity switch<br />Support control assistance power on\/off<br />Support control cruise on\/off <br />Controller characteristics<br />Support external speed test hall sensor <br />Support brake power cut off sensor<br />Support non-zero start(motor hall\/outside speed test hall both are ok)<br />Support high differential motor&amp;gt;5000revolution<br /> <br />LCD meter characteristics:<br /><br />Meter switch control bike electric switch, if meter on then whole bike electric switch is on, if meter off then whole bike power off.<br />Support meter hibernate, if no action for 3minutes, the bike is in hibernation mode <br />(this mode: meter has no 0 gear, whole bike power off, press button to restart)<br />Long press c button control assistance power on\/off, default setting assistance power is on; <br />short press c button control light on\/off(under model that has light port)<br /> <br />0 gear-assistance power 50%, (7A), throttle 100%, (approximate 35mile)<br />1 gear-assistance power20%, (3A), throttle 30%, (approximate 6mile)<br />2 gear-assistance power 40%, (5.5A), throttle 45%, (approximate 13mile)<br />3 gear-assistance power 60%, (8.5A), throttle 60%, (approximate 20mile)<br />4 gear-assistance power 80%, (11A), throttle 80%, (approximate 27mile)<br />5 gear-assistance power 100%, (14A), throttle 100%, (approximate 35mile)<br /> <br />Controller function brief introduction:<br /><br />1.Speed control handlebar throttle: can connected with common handle bar, potentiometer, pedal accelerator, <br />default start stationary state: green signal wire has 0.8v voltage, when reach to 1v, bike moves, and reach to 3.4v,<br /> bike reach to full speed, if 3.6-4.2v, bike will not move.<br />2.Brake and cut off power-low level brake, connect with brake handle switch, after the operation of mechanical brake, <br />cut off signal into controller, the controller is cut off power.<br />3.Speed limit adjustable-adjust the motor maximum rotating speed at any rate by turning button,<br />mainly used to adjust bike top speed, or rotative speed difference of two motors.<br />4. 1:1 power assistance &amp;ndash;this function mainly used on pedal electric bike, (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
