Now, Airwheel self-balancing electric scooter has been acknowledged all over the world and has become a household name for scooter lovers. In general, Airwheel self-balancing electric scooters can be divided into four categories, namely the single-wheeled electric scooter, twin-wheeled electric scooter, two wheel electric scooter and electric skateboard. Among the four classifications, the two wheel electric scooters contain the largest members, such as the Airwheel S series, A series and Z series.

Airwheel S series and A series belong to the self-balancing electric scooters, adopting aerospace attitude control theory, fuzzy software algorithm and gyroscope system to maintain balance by leaning forward and backward.

There are six members in Airwheel S series, the S3, S3T, S5, S6, S8 and S9 self-balancing 2 wheels scooters. As the founding member of Airwheel S series, the S3 ushers in the era of two-wheeled scooter. The two-wheeled design shows its innovative nature and ensures the excellent ability to keep balance. This advantage made it more suitable for those beginners.

Airwheel S5 is seen as an upgraded version with longer range and better outdoor performance. Airwheel S6 opens a new path by adding a saddle to realize two riding modes. Following S6, Airwheel S8 and S9 are improved, S9 in particular. It is positioned as intelligent wheeled mobile robot to avoid obstacle automatically and design the road path intelligently.  

Such advanced technology, as the hydraulic suspension, the comfortable seat and the wireless connection into the mobile phone have been added into Airwheel A3, the pioneer in sitting posture self-balancing scooter. Two members Z3 and Z5 intelligent electric scooters are in Airwheel Z series, which are not controlled by leaning forward or backword. They are well acclaimed for the considerate designs, such as the replaceable battery design, the comfortable riding posture and so on.
