I've been traveling and saw this last week in Stockholm... Beautiful ride... really makes me want to build one!
It reminds me a lot of the small custom cars at maker faire when I went a couple years ago... those guys were getting great gas mileage without much aero work, just because of the small frontal area.
This one had uncovered front wheels and a fairly smooth body... There was a V-twin engine set above the front axle, without any body around it, probably for looks, although i'd bet it was air cooled...
