The following is copied and pasted from the Boss Hoss web page

The Boss Hoss has a specially designed two speed automatic transmission shifted manually from a standard motorcycle style shifter. Just push down on the shifter to engage the transmission from neutral to first, then at the desired RPM and speed, push it down again for second. In second, the engine will turn a pleasant 2300 RPM at 70 miles per hour which generates 30 miles per gallon and a range of more than 250 miles. Reverse is engaged from neutral position by pushing down on the rear shifter and simultaneously holding a button located on the left handlebar just below the left turn signal switch. Reverse is powered by the engine and is specially designed to engage smoothly and be very controllable for a rider friendly feature. The Boss Hoss is definitely the ultimate ride!
