Evo's two speed transmission is a marvel of scooter technology. This transmission successfully implements the reliability and power of a cog belt driven transmission and the versatility of a two speed drive train in a robust and durable package.
The transmission consists of five gears: two for 1st gear, two for 2nd gear and one for the final drive. These five gears power three belts: two for the transmissions 1st and 2nd gear and one for the final output which drives the rear wheel.This transmission is featured on Evo Powerboards' 2 and 2x. The Evo slipper clutch transmission and Evo belt-chain transmission share much in common with this item.
