The Orbitwheel is an intriguing variety of roller skate in which multiple wheels are replaced by a single ten-inch wheel. The rider places each foot inside an Orbitwheel and moves with a wave-like motion, reminiscent of longboarding or Freeline skating. The Orbitwheel was created by inventist. It is available at Hammacher Schlemmer.
