Stationary bike

Abstract

A stationary bike frame of fitness equipment comprised of a dancer pivoted to the frame and driven by a pair of pedals to engage in reciprocal motion at high frequency; a belt for the user to wear being drawn by the reciprocal motion of the dancer to create vibration at high frequency for fat reduction of a particular part of the body where the belt is worn by the user while simulating the motion of riding a bike.
