Cr cleanup [y] trip Km S7 Select Mph or Km b1 Brightness backlight change OFF Auto off [the number represent minutes to shutdown] Hd Wheel diameter b0 Battery volt [36] Pd Password [1919] SL Speed limit [default is 25km/h] you can change speed limit in screen display BUT is not working Display will automatically quit menu when there is no operation for 7 seconds. Double locking has done Xiaomi - ΗΙΜΟ and I imagine the only way to unlock the speed limit is the controller change. * Whatever you do, the final speed with electricity is 25km. From there +km only foot strength.- * Power button (on bottom): to turn on/off Trip button (on bottom): to change trip and total mileage +/- button: to change modes long press + button: turn on/off lights long press – button: switch to parking mode ps If something happens to ebike after the screen teasing, I have no responsibility. #BiciElettrica
