Choose the Primo Gen 4 if
its battery is 259 Wh bigger, so you charge less often on long rides; its low step frame is easier to get on and off; its hub motor means less drivetrain wear and simpler servicing.
Choose the Nova if
it has 20 Nm more torque for steep hills and heavy loads; it is 2 kg lighter to lift onto a rack, train or stairs; its mid-drive motor works through the gears, which feels more natural on climbs.
