  Body Sway Drives Eccentric Bicycle 15 Miles Per Hour
  CALLED the simplest self-propelled vehicle in the world, a radically new type of bicycle, entirely without pedals, is driven by body motion alone.
  The rear wheel of this “x-ercycle,” as it is called, is eccentric; the rider stands on a springy footboard and swings his body in rhythm with the up and down movement of the frame to produce forward motion.
  After acquiring the correct rhythm of movement a rider can travel long distances comfortably at speeds as high as 15 miles an hour, according to the two Chicago brothers who are its designers.
  The axle of the rear wheel is mounted some distance from the true center by using wire spokes of different lengths.
explanation: The document describes a novel bicycle design called the "x-ercycle," which is propelled by the rider's body motion rather than pedals. It mentions that the bicycle can reach speeds of up to 15 miles per hour. The text does not contain any math questions or answers.
