The display automatically estimates the battery life, and gives battery maintenance warnings when the number of charge/discharge cycles exceeds the set value. When the accumulated riding distance exceeds the set value, the display will also prompt bicycle maintenance necessity.
battery charge/discharge cycles exceeds the set value) Mode indication: it displays the current PAS level (Level 1 to Level 5); if there is no numeric display, it means that there is no assistance. If the rider is walking and pushing his/her bicycle, only the symbol will be displayed.
In the manual gearshift mode, press the "up" or "down" key to switch the PAS level to change the motor assist power. The lowest PAS level is Level 1 and the highest level is Level 5. When the display is on, the default PAS level is Level 1. It indicates no power assist when there is no numeric PAS level display.
Mode Switch Interface Headlight/ Backlight Switch After pressing and holding the "headlight" key for 2 seconds, both the taillight and the display backlight (needing the support from the controller) will be turned on. Press and hold the headlight again for 2 seconds to power off the headlight and the display backlight (If the display is turned on in a dark environment, the backlight/ headlight will be automatically turned on.
Walk Assistance Mode Switch Interface Battery Level Indication When the battery voltage is normal, the battery is indicated by a certain number of segments with the border lighted according to the actual quantity of electricity. It the battery is under-voltage, all of the 10 segments will black out with the border blinking, indicating that the battery needs to be charged immediately.

This figure indicates the minute that it takes to automatically shut down the display.
Maintenance Warning Interface The display will prompt maintenance necessity based on such information as the accumulated riding distance and the battery charge/discharge cycles. When the accumulated riding distance exceeds 5,000 km (can be customized by the bicycle manufacturer) , there will prompt, on the display, the symbol the sign of accumulated riding distance will flash for 4 seconds when the display is started up, indicating the bicycle needs maintenance.
