Operating Instructions

Your BAFANG electric bike conversion kit offers multiple riding modes to suit various preferences and terrains.

Riding Modes:

  • E-bike Mode (Throttle Only): Use the thumb throttle to engage the motor and propel the bike without pedaling. This mode is ideal for effortless cruising or when you need a quick burst of speed.
  • Pedal-Assisted Bicycle Mode (PAS): The Pedal Assist Sensor (PAS) detects your pedaling and provides motor assistance, making pedaling easier. You can typically adjust the level of assistance via the LCD display. This mode extends battery life and provides a natural riding feel.
  • Push-Assisted Bicycle Mode: Some displays offer a walk-assist function, providing low-speed motor assistance when pushing the bike, useful for navigating pedestrian areas or steep inclines while walking.
  • Normal Bicycle Mode: The kit can be ridden as a traditional bicycle without any motor assistance, allowing you to exercise and conserve battery power.
