                  The little 'e' at the start of the eSuperSport's name is the 
                  clue to this bikes powerplant... Yes, it's electric. 
                   
                  The Roehr eSuperSport is based around the Korean Hyosung 
                  GT650R's chassis, but with the engine swapped for an AC 
                  induction electric motor, and the badging swapped for "made 
                  in America" Roehr units. 
                   
                  Having said that, the Roehr eSuperSport's conversion is fairly 
                  comprehensive and well engineered. The motor offers up 67 horsepower 
                  and 80 lb-ft of torque. Not bad considering the current crop 
                  of electric bikes on the market. 
                   
                  With its single AC induction electric motor, supplied by LiFePO4 
                  (Lithium iron phosphate) batteries with a capacity of 7.7 KWh, 
                  the Roehr eSuperSport can top 100 mph. The range is approximately 
                  75 miles, and a full charge takes around 7 hours using the built-in 
                  15 amp charger. 
                   
                  The Roehr eSuperSport's battery pack is monitored and protected 
                  by a Battery Management System which controls battery charging 
                  functions, low voltage warning/intervention, and cell balancing 
                  between the batteries.  
                   
                  The biggest downside to the Roehr eSuperSport is the price. 
                  $17,995 is what it retails for - easily twice the price of a 
                  comparable-sized conventionally powered bike. On the upside, 
                  early adopters of the electric motorbike now have another option 
                  to check out.
