AirWheel S3 Introduction

      Airwheel is the state-of-the-art means of transportation adopting aerospace attitude control theory, fuzzy software algorithm, and gyroscope system to maintain balance by leaning forward and backward. Riders can control the vehicle to go forward, accelerate, decelerate, brake, etc. by leaning forward or backward. Also, turning on S3 is controlled by the presence of a handlebar and a vertically ascending shaft. The lateral movement of the handlebar will cause the differential of rotational speed on both wheels, e.g when the shaft is swung to the left, the rotational speed on the right wheel will be faster than that on the left wheel, thus the unit will turn left.

     Airwheel S3 is the greenest and lightest smart unicycle which can be easily carried into buses or subways, facilitating daily commute.


Check Packing Contents

     Open the packing box and carefully take out the handle bar and control shaft. Then take out the wheel assembly.

Given the weight of the wheel assembly, please heave it upward with care. Better find someone for necessary help. Please pay attention to your hands and the front and rear end of the wheel assembly, and avoid lifting it by the dirt covers, otherwise your fingers may be caught.


     Before installation, please find in the standard accessories a set of 2 hexagon wrenches. Please retain this tool kit, it is useful for maintenance and transportation of the unit. As metric standard tools, you may find replacement at home or in a hardware store.

     A pair of work gloves is recommended to protect your hands from dirt and scracthes.

Install the Handlebar and Control Shaft

     Take out the handlebar and control shaft, insert the handlebar into the slot as shown below.Then install the handlebar and shaft assembly onto the wheel assembly and fasten the fixing knob clockwise.



Unfasten the fixing knob before installing or removing the control shaft, then insert the control shaft vertically into the base on the wheel assembly and fasten the fixing knob. Make sure to install the control shaft as shown ticked above (line the inner hole with the outer hole). An overly tightened fixing knob will cause a fixed connection. On the other hand, a loosened fixing knob may cause dangerous detachment.

Install the Battery Case

     Take out 5 M6*20 hexagon screws, fix them into the screw holes on the battery case with a 5mm hexagon wrench, and make sure the battery case and the base are firmly connected.



Lay flat the unit and install the battery case onto it, then fasten the screws.


Use a soft cloth or foam chunks to protect the unit against scratches when it’s laid flat. Make sure the battery case is well connected and screws are fastened. Erect the unit vertically and try to power it on and off to check if the indication panel is working properly.

Safety Guidelines and Riding Etiquettes

     Please learn and abide by local laws and regulations when riding Airwheel. Be careful and considerate of others, and take precaution of accidents and collisions.

     Please ride at safe and proper speed and make sure your Airwheel is under control. Keep yourself a safe distance from pedestrians and vehicles and always be prepared to stop.

     Respect pedestrians and avoid startling pedestrians, especially children. When approaching from behind, announce yourself and slow down to walking speed when passing. Pass on the left whenever possible. When approaching a pedestrian from the front, stay to the right and slow down.

     Keep a safe distance from other Airwheel riders and always avert from obstacles. Unless there’s ample space for other pedestrians, please do not ride side by side with fellow Airwheel players.

     Please avoid riding in poor light unless necessary, and make sure in this scenario you ride at slow, safe speed with care and geared with mounted driving lights if possible.

     Please relax your body when riding, bend your knees and elbows slightly and look straight forward.

     Riding backward can be dangerous. For emergency, ride slowly backward in neccesary avoidance of obstacles.

Please lean forward slightly to accelerate instead of lunging forward suddenly. You my lose balance and get yourself hurt in aggressive acceleration. It is the main cause of accidental falling overs.
