Concept racing bicycle
50cc Kreidler roadracing motorcycle, circa 1980.
KTM 125cc roadracing bike, circa 2012.
The actual ergonomics of efficient pedaling may not be realized, then again, with no human in the photo to ascertain the bar, seat, pedal relationship, we will just have to speculate.
The bicycle sure looks cool, though, and it looks pretty darn aero, too.
