• Level Indicator: Levels 1-5 are displayed. If no numeric display is shown, it indicates no motor assistance.
• Distance Modes: Displays maximum speed (MXA), average speed (AVG), trip distance (TRIP), total distance (TOTAL), remaining range (RANGE), motor power (W), and energy consumption.

Button Definitions

The control unit has the following buttons:

• Up button (+)
• Down button (-)
• Power/Mode button (i)
• Headlight button (?)
• Switch button (<0xE2><0x9A><0xA1>)
• Mode button (⚙️)

Operation

• ON/OFF Switch: Press and hold the power button for 2 seconds to turn the display on or off. The display will automatically turn off after 5 minutes of inactivity (this setting is adjustable).
• Assist Mode Selection: In manual mode, press the '+' or '-' buttons to select the desired assist level (1 is the lowest, 5 is the highest). Level 1 is the default when the display is on. If no numeric display is shown, there is no power assistance.
• Switching Between Distance and Speed Modes: Briefly press the 'i' button to cycle through distance and speed information (TRIP, TOTAL, MAXS, AVG, RANGE, C).
• Headlight/Display Backlight Switch: Press and hold the headlight button for 2 seconds to turn on the display backlight, front light, and rear light. Press again for 2 seconds to turn them off. There are 5 adjustable brightness levels.
• Walk Assistance: Press and hold the power button for 2 seconds to enter walk assist mode, indicated by the 'WALK' symbol. Releasing the button exits this mode.
• Battery Status: The battery level is indicated by illuminated segments. If all segments are off and the border blinks, the battery needs immediate charging.

Battery Charging: Connect the USB cable to the display's USB port. The display will turn on and begin charging. Maximum charging voltage is 5V, and maximum charging current is 500mA.

Preparing Settings

With the display active, press the 'i' button twice (within 0.3 seconds) to enter the MENU settings. Press the 'i' button twice again (within 0.3 seconds) to return to the main menu.

To set parameters, when the desired parameter flashes, use '+' or '-' to adjust the value. Briefly press 'i' to move to the next parameter. Press 'i' twice (within 0.3 seconds) to exit the submenu. If no operation is performed for 10 seconds, the display returns to the normal riding view.

Data Reset

Press the 'i' button twice (within 0.3 seconds) to enter MENU. The speed field will show 'tC'. Pressing '+' will also display 'y'. All temporary data, such as MAXS, AVG, and TRIP distance, can be cleared.

Data is not cleared if the light detection function is set to 0 or is off.

Switch km/mile

When the speed field shows 'S7', press '+' or '-' to switch between km/h and mph, or to set km or miles. After this setting, briefly press 'i' (within 0.3 seconds) to access the light sensitivity setting.

Light Sensitivity

When the speed field shows 'bL0', use '+' or '-' to select a value between 0 and 5. A higher value means greater light sensitivity. After this setting, briefly press 'i' (within 0.3 seconds) to access the backlight brightness setting.

Display Backlight

When the speed field shows 'bL1', press '+' or '-' to select a value between 1 and 5. Level 1 is the lowest brightness, and level 5 is the maximum brightness. After this setting, briefly press 'i' (within 0.3 seconds) to access the auto power off time setting.

Automatic Power Off Time

When the speed field shows 'OFF', press '+' or '-' to select a value between 1 and 9. These numbers indicate the minutes until the display automatically powers off. After this setting, briefly press 'i' (within 0.3 seconds) to access the maintenance warning setting.

Maintenance Warning Settings

When the speed field shows 'nnA', press '+' or '-' to select 0 (disable) or 1 (enable). After this setting, briefly press 'i' (within 0.3 seconds) to access the password entry setting.

The display will prompt for maintenance based on accumulated distance and battery charge cycles.

• If total accumulated distance exceeds 5,000 km (customizable), the display shows 'SERVICE'. The distance indicator will flash for 4 seconds upon startup.
• If the number of battery charge cycles exceeds 100 (customizable), the display shows 'SERVICE'. The battery indicator will flash for 4 seconds upon startup.
• The maintenance warning function can be disabled by setting (MA) to 0.

Wheel Size Setting

When the speed field shows 'Wd', you can set the wheel size. Measurements are in inches. An incorrect wheel diameter can lead to abnormal speed indications. After this setting, briefly press 'i' (within 0.3 seconds) to access the speed limit setting. If wheel size needs to be reset, use BESST and follow the instructions.

Speed Indication

When the speed field shows 'SPL', the distance field shows the speed limit. Press 'i' (within 0.3 seconds) to access the battery communication menu. To reset the speed limit, use BESST and follow the instructions.
