Our take

ADO Air 28 Ultra

The Ultra is the upgraded Air 28: a Bafang H730 three-speed automatic motor (vs the Pro's H700 two-speed), giving roughly 24% more torque in low-speed mode. Battery, range, frame, brakes and weight are otherwise identical to the Air 28 Pro.

Engwe O20 Boost

The comfort-and-range pick. A fuller-size, planted ride with a big 720 Wh battery and a 75 Nm torque sensor that flatters your pedalling. It folds too, but it is heavier than the Zip, so it suits being your main everyday bike more than something to lug onto trains daily. Choose it for cushion and range over outright portability.
