How many gears does ADO Air 20 have? How many speed levels?
ADO Air 20 has one gear and 3 levels of pedal assist. Thanks to our smart torque sensor that calculates the speed, the pedaling frequency, and the torque at the same time, multiple gears would not be necessary, as our assistance system will automatically match every pedal. With our one-gear system, we use a Gates carbon belt drive train, so the whole bike becomes lighter, quieter, and easier to maintain.
