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.
