5.2. Riding Modes
The bike supports three riding modes:
- Pedal Assist Mode (PAS): The motor provides assistance as you pedal. You can adjust the level of assistance (1-5 levels) via the LCD display. Higher levels provide more power.

- Normal Bicycle Mode: Ride the bike like a traditional bicycle without any motor assistance.
5.3. Gear Shifting
Your bike is equipped with a Shimano 7-speed gear system. Use the shifter on the handlebars to change gears according to terrain and desired speed. Shift to lower gears for climbing hills and higher gears for flat terrain or downhill riding.
