At a glance
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.
