What Automatic Shifting Changes on a Small-Wheel E-Bike
QR Code Link to This Post
The ADO Air 20 Pro 2026 uses a BAFANG automatic two-speed motor. Its motor is rated at 250W with 50N·m of torque, and the transmission changes between two speeds automatically. The bike also uses a dual-sided torque sensor that responds to the rider's pedalling input.
This creates a different riding setup from a conventional bicycle with manually operated gears. Instead of reaching for a shifter whenever the road changes, the rider can concentrate more on pedalling and steering while the automatic system handles its two-speed transmission.
The Air 20 Pro also offers Eco and Sport modes. Eco is intended for cruising and extended range, while Sport provides a 33.3% power boost according to the product information.
With a maximum assisted speed of 25 km/h and a claimed maximum range of 100 km, the bike is clearly designed around everyday electric assistance rather than simply being a traditional folding bicycle with a motor added to it.
For anyone comparing e-bikes, automatic shifting is worth considering as part of the overall riding experience rather than simply treating it as another specification.
