Roehr eSuperBike: $27,595, 210lb/ft, Hyosung GT250R frame

Dailies -


Roehr-eSuperBike-1.jpgWhen 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.
Roehr-eSuperBike-2.jpgSo 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.

Roehr-eSuperBike-3.jpgThree 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

    500lbs is just too much for a sport bike… This isn’t 1993! To be fair I guess it is more like 1900 for electric bikes.

    Can’t believe I did not realize that was a GT250R. I have one in my garage. Thought it looked familiar. Nice work.

    The GT250R frame was originally engineered to play double duty as a 250 and a 600. Later Hyosung decided to build a metal trellis frame that is currently used on the Hyosung GT650.

    So, the frame is pretty beefy. I’ll try to dig up some links to support this.

  • skadamo

    Sorry, best I could find…

    Pic does show the 650cc (600 was planned) liquid cooled motor in the 250 frame.

    The Hyosung uses a steel frame, so strength is not the issue. Balance, and poise under high stress loads is, particularly when the same poor frame is asked to cope with almost three times the torque.

    All in all, it presents the least fantasy scenario so far presented in the electric retail universe

  • Sean Smith

    So does it get the same horrible suspension from the 250R?

  • Mitch

    I know that all this stuff is totally still in it’s infancy, sort of like powered flight in the early part of last century.

    But man, that looks ghetto as hell.

  • damien

    Please correct me if I’m wrong, but isn’t Hyosung somehow connected to Suzuki? Or maybe use old Suzuki designs or something? Thought I’d heard something to that effect.

    • Mark D.

      Damien, I believe they do contract work for Suzuki in Korea. That is, they operate factories that build Suzuki parts/bikes for Suzuki in Korea; I believe they’ve also done some joint R&D. But all the Hyosung bikes are their own designs; I’m sure they’ve taken what they’ve learned from Suzuki, though! The GT650 engine is pretty close to the SV650′s engine, though certainly not identical.

    Very good packageing. A good job. $16k is what a ‘no-comprimizes’ 50hp(peak) ‘leccy is going to cost, for an entry-level bike. The double motor one is cool also.

    You would need to race it to find out, but my gut says the chassie will hold up pretty good. You tend to ride a bit smoother with a ‘leccy.

    He deserves a big bulltaco thumbs up.

    Keep in mind guys, the batt on that bike is between six and ten grand, all by itself.

    GO ROEHR! I’m so excited by what these guys are doing, I can hardly contain it. Unlike Mission, who admittedly hava a very interesting prototype, Roehr has focused on the product, not hype. I think he’ll be a great success with this new venture, probably much more so than his IC bike. Early on, there was talk that maybe one could buy the ‘entry-level’ model, and later add batteries & the second motor in the future. The idea of ‘upgradeable’, modular systems could really be an interesting development; instead of upgrading by buying a whole new motorcycle, one would just bring your bike into the shop, where they would add additional power/range. Interesting stuff.
