Becuase walking is far too difficult
Elliptical Machines | June 18, 2008
People who think walking is too much trouble, this one’s for you. It’s a design by one Regimantas Vegele for a device that’s part Segway, part elliptical machine. Officially called Zingsniuoklis, you work it by stepping on the pedals, but rather than remaining stationary (as in the elliptical machine) your legs power forward movement.
