Zero Motorcycles has made the logical next step in its bike line-up by now offering a Supermoto version of its electric dirtbike, the Zero X. Zero has added 17″ street tires and a projector headlamp to make the transition necessary from dirt-track to city streets. With 31 horses and 62.5 lb-ft of torque instantly available, the clutchless one-speed “S” should make it up to 60 mph. Its four kWh battery lasts up to 60 miles, and can be recharged with the integrated charger, which will charge the battery up in less than four hours.
