Agility, speed, and portability were the guiding forces behind the development of the 3-wheeled Aphaenogaster scooter.  A 24 volt battery powers a 350 watt motor, which in turn drives the rear wheel at speeds of up to 15 mph and a range of up to 8 miles.  The rider sits on a padded seat atop the rear assembly, and steers the front wheels with forward and backward motion of the control stick.  A twist grip activates the proportional throttle, while a hand lever activates the rear disc brake.  With mono-shock, rear light, side lights, and front spot and headlights.
