How to install the P.wheel Electric Bike Booster?
First Use: Exit Shipping Mode
Smart Shipping Mode suspends power to the main circuit board to reduce standby drain during transport and extended storage. Connect a compatible charger and begin charging to restore power to the board, exit Shipping Mode, and activate P.wheel.
⚠️ CRITICAL: MOUNT BEFORE POWERING
Complete the mechanical installation and clamp P.wheel securely onto your seatpost before pressing the power button. The gyroscope needs to calibrate with the unit in its installed riding position. Turning it on before mounting may trigger tilt protection and temporarily lock the motor.
💡 If the unit was powered on before mounting and the motor becomes locked, hold the power button for approximately 10 seconds to reset it. Then reconnect the charger and begin charging to reactivate the unit before trying again.
Onboard & App Mode Control
Switch between all four assistance levels using the built-in buttons or the P.wheel App. No phone connection is needed when using the onboard controls. MOD is the default setting.
Bidirectional USB-C Charging
Recharge P.wheel with a compatible USB-C phone charger, or use its battery to power compatible portable devices. We recommend a USB-C PD fast charger rated at 45 W or higher for faster charging. Lower-power compatible chargers can also be used, but charging will take longer.
The charging port has moved from the top of the unit to the underside, reducing direct exposure to rain compared with the previous design.
