Even in a still picture, the scooting motion required to ride the Fliz is apparent

Fliz bike combines walking & cycling

The Fliz (which refers to the German word "flitzen" – meaning to whiz or dash) harks back to the days before the bicycle design we know and love was almost universally settled upon. It has more in common with the Laufmaschine (or hobby-horse) invented by Baron Karl Drais in 1817. Like the Laufmaschine, the Fliz has no pedals, instead relying on a scooting motion made by the rider. You're essentially pacing (half-walking, half-running) but traveling faster and further than you would normally, thanks to the presence of two wheels.

Where the Fliz differs greatly from Drais' invention, which was truly innovative at the time it was realized, is that rather than sit on the frame, the rider hangs from it in a harness system – which we've seen before with the StreetFlyer. They're bent forward at all times, with their hands resting on the handlebars and their head sitting through the front of the frame. That frame is made from a glass and carbon fiber laminate and designed for people around 1.85 meters (six feet) in height. The belt is custom-built for each user and allows for a fast and easy release thanks to the five-point fastener.
