stiff bikes...

WOUTER JAGER, KOGA MANAGING DIRECTOR, SAYING:
"What makes it unique is that it's overdesigned on stiffness. A
normal human being could not ride this bicycle. You would immediately fall off
and feel like riding on a concrete block, for example. It's so stiff that it
doesn't behave like a normal bicycle, and obviously the strange element is
this bicycle doesn't have a brake, doesn't have a gear, it's a single speed,
no lights or whatever, but still it is the most difficult bike to ride,
because obviously you're riding at the speed of over 70 km per hour without
brakes, so it is very special."
