When these pictures, the first ever of the new eRoehrs, first popped up on, I knew I'd seen that frame before somewhere. CBR600F3? Nope. '90s ZX6-R? Nope. What the hell is it? I called Walter Roehrich, the man behind Roehr, and asked him. Turns out its a Hyosung GT250R frame modified with reinforced swingarm pivots and battery mounts at the Korean company's factory.


So why a Korean frame on an expensive, electric, American sportsbike?
Cost. Roehr looked at simply adding an electric powertrain to the
V-Rod-powered 1250sc superbike, but the cost would have been staggering,
north of $70,000. But Walter didn't want to compete with Mission
Motors, he wanted to give buyers world-class electric performance at as
an affordable price as possible.


Three bikes are planned for the eRoehr range, all based around this
basic configuration:


$16,965; a single AC induction motor putting out 48bhp and 105lb/ft
(peak); 6kWh Lithium-Iron Phosphate battery pack; 375lbs weight.

eSuperBike (pictured)

$27,595; two AC induction motors; 96bhp, 210lb/ft (peak); 9.6kWh.


$34,495; Ohlins suspension, 320mm Brembo radial brakes, forged
Marchessini wheels.

If you think the eSuperBikeRR sounds like an ideal TTXGP entry you're
not alone. While Walter was hoping to enter the electric racing series
this year, development is taking longer than expected so he had to
choose between delivery bikes to customers this summer, as promised, or
racing. He chose to keep his promise, but hopes to race next season.

According to our Dummy's guide to electric motorcycles, AC induction
motors are "the king of motors," combining good efficiency with solid
power delivery. The Mission One will also use AC induction.

To put the price into perspective, the 2010 Zero DS only has a 4kWh, a
less sophisticated single brushed DC permanent magnet motor and retails
for $9,950.

How's that Hyosung frame going to hold up with all those batteries
shoved in it? better than you might think. Even before the modifications
made to Roehrs specs, its made to support a bike that weighs 377 Lbs,
two more than eSuperSport. While the eSuperBikes add considerably to
that weight, the over-engineered frame should still be well
within its tolerances., PlugBike, Roehr
