Karsten Bettin, inventor:

"Originally I wanted to build a bike that you can ride comfortably standing up, upright and not bending over, just as we humans are built. It quickly became clear that it would also be possible to fold it up very small. The result is a fascinating new riding experience, a great movement the likes of which the world has never seen. And a useful device with which you can move absolutely freely in the city. I don't really need a folding bike, but I really need a Kwiggle."
