Build Your Own ELECTRIC MOTORCYCLE
The finished project is a 1981 Kawasaki KZ440, converted to electric. It is powered by four Optima Yellow Top sealed (AGM) lead-acid batteries, that drive a Briggs & Stratton Etek electric motor. The speed of the motor is controlled by an Alltrax brand "AXE" programmable controller that can run at up to 48 volts and 300 amps. Contrary to popular belief, and electric motorcycle is NOT silent, but is CONSIDERABLY quieter than a typical gas cycle. The cycle is GEARED to 45 mph, has fairly good acceleration, no clutch or transmission. There's no oil to change, to mufflers to rust off, no air filter, no carbs to tweak, and no gasoline.
