21

accuracy. Wheel size includes 08?10?12?14?16?18?20?22? 26?28,choose in turn,interface is as below:

“"1":wheel size setting mode

"26":wheel size

2.8.2 Battery voltage setting

Hold0.5s to go to voltage setting interface, hold0.5s to choose

right voltage to make sure the display works normally. There are two options of 24V and 36V, choose it in turn, interface is as below:

"2":voltage setting mode

"36":battery voltage

2.8.3 Single mileage reset

Press 0.5s to go into the single riding distance setting interface,

press 0.5s to clear the riding distance to zero, interface is as

22

below:

"3":riding distance reset

2.8.4 Exit the setting state

In the state of parameter setting, hold and for 3s to save the

current settings and exit the setting interface.

Attention: With no action for 5 seconds, it will exit the setting interface automatically, and the adjustment will not be saved.
