Installation Steps

**Choose the Adaptor

Note:** It is essential to use an adaptor that is exactly the same diameter as the seat post. Otherwise, it may cause damage to the seat post and affect the normal operation of the power assist.

Remove the bicycle seat post and find the seat post adaptor that matches the diameter of the seat post precisely.

Note: If the diameter of your bicycle seat post exceeds 31.6mm, please replace the seat post with a 31.6mm one (You can add a seat post shim to facilitate the change in diameter of the bicycle seat post.).

**Insert the Adaptor and Seat Post Clamp

** Insert the seat post adaptor into the bicycle seat post and then insert the seat post clamp.

**Reinsert the Seat Post into the Bicycle

** Reinsert the bicycle seat post into the bicycle seat tube and adjust it to the appropriate riding height.

**Install the Power Assist

** Align the drive wheel of the power assist with the rear wheel of the bicycle, and fix the clamp into the seat post adaptor.

**Adjust the Angle

**

1. The optimal downward movement distance is less than or equal to 5mm.
2. The seat post adaptor can be adjusted slightly – up and down to change the angle of the power assist.

Rotate the gear shift knob towards the “Lock” direction to secure the clamp onto the seat post adapter. Press down on the rear end of the power assist, allowing slight up and down movement of the seat post adaptor until the downward movement space is less than 5mm for the optimal power assist position.

Note: When tightening (or loosening), please grip both sides of the knobs with both hands and rotate simultaneously.

**Secure

** Keep the seat post adaptor in the optimal power assist position, tighten the gear shift knob, and use the hex wrench to secure the seat post clamp.

User Instructions

Power On/Off

**Power On

** Press and hold the power button until all the lights in the power indicator ring illuminate, then release your hand. The device will turn on, and the power assist enters standby mode.

Light Indicators:

• Power Indicator Ring (Top): Constantly lit in a breathing pattern after turning on.
  Battery Indicator Light (Side): Constantly lit after turning on, displaying battery level. During cycling, it flows in a water- like pattern, and the flow frequency is positively correlated with cycling speed.

• Tail Light (Rear): After turning on, it blinks, and the blinking frequency is positively correlated with cycling speed.

Power Off
Press and hold the power button until all the lights in the power indicator ring are extinguished, then release your hand. The device will turn off.

Note: If the power assist is not used within 5 minutes after turning on, it will automatically power off.

Battery Level Display and Charging

Battery Indicator Light:

1. Battery Level Display
   Battery Level≥ 75%:
   75% > Battery Level> 50%:
   50% ≥ Battery Level > 25%:
   Battery Level≤25%:
   Note : When the battery level is below 25%, the battery indicator light displays red as a low battery warning. Please charge promptly.

2. Charging
   The battery is not fully charged when it leaves the factory, so please fully charge it before the first use. Use the original charger provided by the manufacturer.

Insert the charging plug into the top charging port, and the indicator lights on both sides will display the current battery level and dynamically show the charging effect. When fully charged, all the indicator lights will be on.
Note: Please charge in the power-off state, and do not turn on the device during the charging process.

Charging Status

Battery Level ≤ 25%:
50% ≥ Battery Level > 25%:
75% > Battery Level > 50%:
75% ≥ Battery Level > 90%:
Battery Level = 100%:

Note: If the power assist is not used for an extended period, the battery should be charged every three months to prevent it from becoming ineffective due to long-term self-discharge.

Cycling

After the power assist is turned on, it automatically enters the automatic power assist mode. When the bicycle speed exceeds 5 km/h, the power assist automatically engages.

• To accelerate, increase the pealing frequency, and the power assist will increase accordingly until the speed exceeds 25 km/h. With the assistance of P.Wheel, lightly pedal, and the bicycle can maintain a maximum speed of 25 km/h.
• To decelerate, there are two ways:
  1. Reduce pealing frequency.
  2. Squeeze the brakes.

The power assist adjusts its power based on the decreased riding speed. At this point, lightly pedal, and P.Wheel can help you maintain the reduced riding speed.

Note : When passing through water sections during cycling, the reduced friction between the wheels and the power assist wheel may lead to a decrease or loss of assistance. This is a normal phenomenon.
