How to ride a bicycle in an airport -- sort of

Bicycle built for four? Or should that be of four? This quirky YouTube video has gotten about a million eyeballs and has been bouncing around the Twitter-sphere. It comes with this straight-faced explanation: “Cruising with a bicycle in Prague airport before boarding a flight back home to Estonia.”

(Be patient when you watch the video; it takes a while before the “bike” appears.)
Which got me wondering about the prospect of using bicycles to scoot from gate to gate in airports. Of course, someone had already thought of that. Jack Becker writes on Third Wave Cycling Blog:

“At an airport of the future, after checking in and passing security, one grabs a small folding-style bicycle and enters highly visible bike lanes, which takes one quickly to the departure gate. Before the hours of sedentary position in the aircraft, it is the last chance to work one’s cardiovascular system. Why not?”

Becker posited this idea after seeing a security officer cycling around Montreal’s airport a few years back. His interest was rekindled when he witnessed airline and airport staffers picking up folding bikes to wheel around Frankfurt’s airport. (Check out the photos with the blog post.)

I like this idea. And what about stationary bikes on airplanes? Sure would solve those pesky legroom problems.
