I have mixed reactions to this German-designed FLIZ bike, as described on the James Dyson Award website, where you can view a short video and see stills.
A part of me is attracted by the "shiny keys" aspect. An other part says, "Why re-invent the wheel?" Or in this case, why re-invent the two-wheeler.
One of the reasons that the velocipede was left in the dust was because the cranks, chains and later, gears, gave a mechanical advantage. The average cyclist can out-travel the average runner.
And really, all the FLIZ does is support the body while running.
Having said that, the FLIZ does get around the problems of saddle compression of the groin area (and underscores how important the groin-saddle contact is controlling the bicycle). It's cool, and the 21st century is all about cool. And it does make us re-consider our concepts of what exactly a bicycle is.
Truly, an ideal Friday time-waster.
