Looks like a backflip waiting to happen.

Roehr Motorcycles, producers of the American-built 180 bhp 1250sc sportbike, is to introduce two electric motorcycles before mid-year, topped by a 96 bhp motorcycle with race level performance, 210 lb/ft of torque, and premium suspension and brake components which it has dubbed the eSuperbike. Significantly, even a lower spec eSupersport model with 48 bhp, 105 lb/ft of torque will top 100 mph. No details have yet been announced on the range of the bikes, but viable electric sports motorcycles are clearly going to be available before the end of the year.

The new electric range will be known as eRoehr and the range-topping superbike will use a high energy discharge, 10 Kwh, lithium iron phosphate battery pack and form the basis of Roehr Motorcycles' entry into the upcoming 2010 US TTXGP series. Roehr Motorcycles will also be offering race prepared versions of the eSuperbike for teams or individuals competing in the upcoming TTXGP, and FIM e-Power racing series'.

Pricing and additional information will be announced over the coming weeks.

Doubt it, the numbers are impressive with electric vehicles, but they always manage to screw up putting that power down through poor drive train/gearing options.

Bet it'll weigh +700lbs

Should be interesting.

so is this the new american boutique sportsbike template? Fail hard at building a gas bike and attempt to go electric?

btw that pic is the gas bike. Electrics dont need akrapovic

Or radiators.

You don't get gov't subsidies or VC these days by building ICE-based bikes (Internal Combustion Engine).

Wanna bet? Any time you transform energy (to motion, convert voltage, etc), you get heat due to efficiency losses. That's why AC adapter power bricks get warm to the touch.

A single AC motor located directly in front of the rear wheel powers the Enertia TTR. Manufactured by Perm Motor in Germany, the compact motor is a brushless, permanent-magnet design that is more efficient and durable than the simpler, less-expensive, brush-type motors most other TTXGP entries used. The peak efficiency rating is 94 percent (compared to approximately 25 percent efficiency for the very best internal-combustion engines), and the motor is liquid-cooled to minimize heat-related losses, with a tiny radiator mounted below the headstock. The motor's continuous-power rating is 20 kW, with a peak power rating of 30 kW. In TTXGP tune, this translates to 30 horsepower and 53 lb.-ft. of torque at the rear wheel. Custom sideplates allow the motor to be mounted as a stressed member, and there is no gearbox or primary drive; the drive sprocket mounts directly to the motor output shaft. A cush drive on the rear hub minimizes driveline lash.

A tiny radiator below the headstock is different than the 2 big radiators on the side of the bike in the picture.
