Electric vehicles push technologies beyond batteries and software. In
pursuit of a lighter bike, the five UMB
engineering students behind this machine took a page from MotoGP and
decided to go all out with carbon fiber construction. The result? A
motorcycle who's combined monocoque frame and bodywork weigh a mere 25
kg (55.12 lbs).
A new electric motorcycle called Roskva is supposed to bring together the amazing technology and environmentally friendly benefits of an electric vehicle with the aesthetically pleasing styling cues of motorcycles with modern parts. A team of five students at the University of Life Sciences (UMB) in Oslo, Norway came up with the concept of the bike and designed on the premise that users will want to “take it out for a ride on a sunny day” to enjoy the riding experience, while still taking it to work on Monday. According to their site, the “Roskva is a machine in which the advantages of environmentally friendly electricity are combined with pure riding experience.”
But 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. 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.
The Roskva electric motorcycle is a fresh, thrilling concept… sure to engage the hearts of young motorcyclists and supermoto enthusiasts alike. The naked-style bike features sharp, angular bodywork, a monocoque carbon fiber chassis and an open, streamlined back end that’s made even cleaner as it lacks an exhaust.
