5.3 Select assistance level on handlebar panel:
When the power is on, you can shift to 3 assistance levels, low middle and high. Press the button "+" and "-",
to shift the assistance level (Low middle and high). Here is the way how to set the assistance level:
 When the power is on, the "middle" LED is on which means the power-assistance is in the 2 nd grade.
Then you can press the "+" and "-" buttons to choose the LOW, MID and HIGH.
 For each level, you can also select an intermediate level of support by always using the "+" or "-"
buttons.
 When selecting the HIGH assistance level, meaning more electric power and less human propulsion are
applied to the bike.
 This level is suitable for uphill, head wind or heavy load riding.
 When shifting to MID assistance level, it means electric and human propulsion almost fifty/fifty applied
to this bike. We suggest you select this assistance level, when riding a regular flat paved road.
 When shifting to LOW assistance level, it means less electric and more human propulsion being applied
to the bike. Therefore, this is an electric saving level (or economical level). We suggest you select this
level when you ride this bike for leisure sports or fitness.
 Acting on the "+" and "-" buttons, it is possible to use three intermediate assistance levels, which can be
activated when, passing from the predefined LOW, MID and HIGH levels, the LEDs will start to flash.
 Moreover, this power display function can also alert users through these four LED lights, as shown
below:
 If the user forgets to turn off the battery switch after five minutes of stopping the ride, the lights of the
four LED will turn one after another. In this way to remind the user to turn off the power immediately to
save energy.
