Q&A

Part 1: LCD Meter Functional Area Distribution

The LCD meter provides a comprehensive display of various functions and indicators for the electric bicycle. Below is a detailed breakdown of the functional areas:

1. Power Display: Shows the current power status.
2. Headlight Indication: Indicates whether the headlights are on or off.
3. Cruise Indication: Displays the cruise control status.
4. Speed Display: Shows the current speed in km/h or mph.
5. Fault Diagnosis: Detects and displays error codes for system malfunctions.
6. Current Speed: Displays the real-time speed of the bicycle.
7. Maximum Speed (MAX): Shows the highest speed achieved during the ride.
8. Average Speed (AVG): Displays the average speed over the ride duration.
9. Unit Display: Toggles between kilometers (KMH) and miles (MPH).
10. E-Bike Mode: Indicates the current mode of operation:
    • Pure Electric Mode (PAS 1-5): The bicycle operates solely on electric power.
    • Power-Assist Mode (PAS 1-5): The motor assists the rider’s pedaling.
    • Riding Mode (PAS 0): The motor does not intervene, and the bicycle operates in pure riding mode.
11. Total Mileage (DOD): Displays the total distance traveled by the bicycle.
12. Single Mileage (TRIP): Shows the distance traveled during the current trip.

Note: In Pure Electric Mode, the accelerator handle is used to control the speed, while in Power-Assist Mode, the motor assists the rider’s pedaling. Gear 0 is a pure riding mode where the motor does not intervene, or the power is turned off.

Part 2: LCD Meter Key Guide

The LCD meter is equipped with buttons for various operations. Below is a guide to the key functions:

1. Horn Button: Activates the bicycle’s horn.
2. Backlight Adjustment: The LCD backlight dims when the headlights are turned on and returns to brightness when the headlights are turned off.
3. Battery Life Mode: Press and hold the - or < key to enter battery life mode. Press the brake or the same key again to cancel this mode.
4. Error Code Display: If the electric control system fails, the LCD meter will automatically display an error code. Refer to the error code table for detailed definitions.
5. Default Display: After powering on, the LCD meter displays the real-time speed (km/h) and total mileage (DOD) by default.
6. Information Switching: Short press the 1 key to switch between total mileage (DOD), single mileage (TRIP), maximum speed (MAX), and average speed (AVG).
7. Power Mode Switching: Short press the + or - key to switch between power modes.
