Roskva Electric Motorcycle launched

Roskva have countered that cost somewhat by going with off-the-shelf components for the powertrain. Twin Lem200 DC motors paired with a set of Kelly controllers are said to put out a peak 94 horsepower while the battery packs appear to be comprised of Headway lithium iron phosphate (LiFePo4) cylindrical cells with a total capacity for 6 kWh. Combined, this set-up is said to be good for a top speed of 180 km/h (112 miles per hour) and offers a range of 100 km (62 miles) though not, of course, at the same time.

Roskva Electric Motorcycle Five Norwegian engineering students from the University of Life Sciences in Oslo have come together to design and build an electric motorcycle that's a little different from the rest of the field. Rather than construct the vehicle around a steel or aluminum frame (like the Brutus we covered last year, for instance), the Roskva bike features a carbon fiber monocoque frame that reportedly weighs less than 25 kg (55 pounds).

Carbon fiber is also the material of choice for the wheels, single-sided swingarm and enclosed driveshaftBut the carbon fiberization doesn't stop there. The battery boxes (which appear to be removable) are also made of the stuff, as well as the single-sided swingarm with its driveshaft (also carbon fiber) hidden away inside. Carbon fiber wheels? Double checkarooni!All that light stuff is expensive, but Roskva have countered that cost somewhat by going with off-the-shelf components for the powertrain.
