remind the user to give ebike a maintenance check once the total mileage reached a preset value. maintenance reminder function can be turned on/off in the setting interface and is turned on by default. The factory default reminding mileage is 5000km which is not modifiable by users, that is, display will remind the user to give a maintenance check once the total mileage reached 5000km.
6.6 Walk assist function When speed is 0, long press button to enter walk assist mode, motor outputs power
according to the set speed and control the actual walk speed, display shows the walk assist icon and the real-time speed. Release button or any other button to exit walk assist mode, the motor is turned off, and the display gets back to the basic interface. Walk assist interface, shown as below

6.7 Battery power indicator and assist power output

Battery power information is divided into battery bar indication and remaining percentage

indication. When battery power is normal, battery capacity is divided into 5 bars. Before

communication is established, the battery percentage is not displayed, and the power bar is full and

blinks at 2Hz. After battery info is acquired, power bar will stop blinking, and displays the power

percentage. If communication is not successful within 3s, it will stop blinking and no power

percentage will be displayed.

After battery capacity is lower than 5% or the voltage is lower than low voltage value, display

will enter the low-voltage mode. In this mode battery level showed level 0 and border blink at 1Hz,

with no power output from the motor, and disabled assist level switch. Power assist level is displayed

as OFF or 0.

To get out of low-voltage mode, reset, and increase the voltage above low-voltage value and

battery capacity above 5%.

Remarks about battery indicator When there is a battery communication error 1. Display will estimate the power according to the voltage and show the battery level accordingly 2. No battery percentage information will be shown 3. Range information will not be displayed 4. If the voltage is lower than the low-voltage value, the effect of the current on voltage needs to be
considered when converting to a voltage at 0 current
