Speed limit setting: st.2 means speed limit setting. The factory default value of
maximum riding speed is 32KM/h (20MPH). Changing this value can set the
maximum riding speed of the electric vehicle. When the riding speed exceeds the set
value, the motor will have no power output to protect the safe driving of the rider.
The maximum speed setting can be selected from 12km/h to 40km/h, by short
pressing the button or button.
Backlight Brightness: st.3 stands for backlight. Parameters 1, 2, and 3 can be set,
and the factory default value is 2. The parameters of the backlight brightness can be
changed by pressing the button or button. 1 is the darkest, 2 is medium, and 3
is the brightest.
The speed limit of pure electric mode is 32Km/h (20MPH), not adjustable, and
this setting cannot change the electric mode speed limit value.
KM/MPH switching: st.4 represents KM/MPH switching. Short press the button
or button to switch between KM and MPH.
Wheel diameter setting: st.1 represents the wheel diameter setting. Because
adjusting the wheel diameter will result in inaccurate speed display and mileage
display, this setting cannot be adjusted.
