112mph carbon-fibre electric prototype

FIVE students from Norway have built an exotic electric sports bike that has a chassis that weighs less than 25kg and is capable of 112mph.

Named the Roskva, the lightweight electric bike utilises carbon fibre in its construction with a self-supporting frame, wheels, drive system and swing arm all made out of the desirable material.

The sporty prototype uses two electric motors and has a claimed output of 92bhp and 59 ft/lbs of torque. The range before charging the Roskva machine is 62 miles.

Seriously? That's almost a 4:1 power-to-weight ratio, that's incredible. Shame the small battery size limits it's range. I'd love to have a look at that frame setup too.

Biggest issue with this would be that it would be really easy to steal, weighing only 25kg anyone would have no trouble picking it up and throwing it in the back of a van.

The biggest issue is the poor research from Visordown. Frame and body weighs 25kg not the whole bike!!!!!

No, the article clearly states the CHASSIS weighs less than 25kg.
