The ZF9 Zero S was the 2012 street model with the 9.0 kWh Z-Force pack and a 420 A controller, and it was the first Zero to pass 100 miles of EPA city range. It uses a lightweight aluminium twin-spar frame, a belt final drive and a one-speed, clutchless drivetrain. At about 155 kg it was a light, quiet commuter-sport machine.
