FAQ
What are the differences between Air 20 Pro and Air 20 Ultra?
The Pro version uses a Bafang built-in two-speed automatic shifting motor, while the Ultra version uses a Bafang built-in three-speed automatic shifting motor. The performance is strong, so if you need to drive on complex sections, the Pro will be a good choice, and if you need to drive on very complex sections, the Ultra is your best choice.
What is the ADOSense Assist System?
Developed jointly by ADO and Bafang, ADOSense is an intelligent riding assist system that combines three core technologies — automatic gear shifting, a torque sensor, and a carbon belt drive — to deliver a smooth and effortless riding experience across all terrains.
By collecting real-time sensor data and applying AI adaptive algorithms with dynamic speed management, the system automatically selects the optimal riding mode based on your speed and road conditions.
Shifting, acceleration, and deceleration are all seamlessly integrated to ensure a stable and fluid ride.
With three gear ratios (0.76 / 1.0 / 1.31), you can always find your most ergonomic and comfortable pedaling rhythm, maintaining a natural cycling feel.
The carbon belt drive system runs quietly, cleanly, and reliably — even in wet or humid environments.
What is an Adjustable Front Fork Suspension?
The AIR 20 PRO｜ULTRA features a lockable front suspension system that ensures a comfortable ride across various terrains. Whether you’re tackling bumpy mountain trails or cruising on smooth city streets, you can easily adjust the front suspension lock to suit the conditions. Lock it on flat roads for improved pedaling efficiency, or unlock it on rough terrain for a smoother, more comfortable riding experience.
