Usage Features

Power On/Off: To turn the display on or off, press and hold the "Power" button for 1 second. The display has an automatic shut-down feature that activates after X minutes (configurable from 0 to 10 minutes) of no operation or riding.

Assist Level Operating: The assist level can be changed by short pressing either the "Power" or "Mode" button. The assist levels range from 0 (neutral) to 9 (top assist level).

Mileage Mode: Double-pressing the "Mode" button (with an interval of less than 0.3 seconds) allows switching between Trip distance and Odometer (ODO). If there is no operation for 5 seconds, the display automatically reverts to the real-time speed display.

Headlight/Backlight On/Off: Double-pressing the "Power" button (with an interval of less than 0.3 seconds) controls the headlight and backlight. Even if the battery voltage is low and the motor is not working, the display can keep the headlight on for a while when the E-bike is in riding.

Walking Mode (6km/h): To enter walking mode, press and hold the "Mode" button for 2 seconds. The walking icon will flash. Releasing the "Mode" button exits this mode. A short press of the "Power" button also exits walking mode.

Parameter Setting: To access the setting menus, press and hold both "Power" and "Mode" buttons simultaneously for 1 second. Within the menu, the "Mode" button changes the parameter setting, and the "Power" button switches to the next item. To exit the menu, press and hold "Power" and "Mode" buttons together for 1 second. The display will automatically exit the menu if there is no operation for 10 seconds, or if riding starts (for safety reasons, the menu cannot be accessed while riding).
