Figure 6: Visual representation of the three riding modes.

1. Human Riding Mode:

   Turn off the power or set the gear to 0. This mode allows you to ride the bike purely with pedal power, similar to a traditional bicycle.

2. Start The Electric Mode:

   Turn on the power supply and twist the throttle (1-5 files) for pure electric riding without pedaling. This mode provides full motor power.

3. Intelligent Power-assisted Mode (Pedelec):

   Turn on the power and select your desired assist level (1-5). The motor will provide assistance as you pedal, making riding easier, especially on inclines or for longer distances. The level of assistance can be adjusted via the LCD display.

Gear Shifting:

Utilize the Shi-Mano 7-speed gear system for optimal pedaling efficiency. Shift gears smoothly by using the trigger shifter on the handlebars. Downshift for climbing hills and upshift for higher speeds on flat terrain.
