3.2 Riding Modes
- Bike Mode (Pedal Only): The electric motor provides no assistance. Ride the bike like a traditional bicycle.
- Pedal-Assist Mode (PAS): The motor provides assistance as you pedal. There are typically multiple levels of assistance (e.g., 1-3) which can be adjusted via the controls on the handlebar.
- Throttle Mode: Engage the throttle to propel the bike without pedaling. This mode provides full electric power up to the maximum speed.
- Walk-Assist Mode: This mode provides low-speed assistance to help you walk the bike, useful for pushing it up inclines or through crowded areas.

3.3 Gear Shifting
The Heybike RaceMax is equipped with a 7-speed gear system. Use the trigger shifter on the handlebar to change gears, allowing you to adapt to different terrains and optimize pedaling efficiency.
