Controller: 24V/36V/48V/52V 26A sine wave controller, compared with the square wave controller, the noise is smaller and more energy-saving, and it is compatible with motors with and without Hall. Display: S866 LCD display, complete workmanship display parameters, such as: battery voltage, speed display, gear display, subtotal mileage, total mileage, etc. A variety of parameters can be adjusted: P parameters can be displayed to adjust the actual situation of the bicycle, such as the brightness of the backlight, the number of gears, the battery voltage, the size of the wheel, the number of power-assisted magnetic points Accelerator: The thumbstick can be installed on the left or right hand side according to the customer's preference, with smooth acceleration and quick return PAS: The package contains an 8-magnet PAS, which can be installed if necessary. If you do not need to install PAS, it will not affect the use

Packaging list:

Simple error code troubleshooting method:

• E07 motor malfunction, usually it is necessary to check if the cable sequence of the motor and controller is consistent (if the motor is not connected, E07 error may also occur)
• E08 throttle malfunction. Generally, it is necessary to check whether the throttle connector is properly connected (E08 error can also occur if the throttle is not connected)General parameter settings:
• P03: Adjust voltage, 24V/36V/48V
• P06: Wheel diameter size setting, unit inch
