ABSTRACT:
This invention relates to an improved fitness bike that fixes a handle support rod and a saddle separated on both ends of a transversal rod, and the bottom of the handle support rod is pivotally coupled with and moved back and forth at a first support rod at the front end of a base, and the lower end of the saddle support rod includes a driving stand, and the upper end of a second support rod disposed at a rear end of the base installs a passive pulley, and a link rod is installed between an eccentric portion of the axle of the passive pulley and a driving stand at a lower end of the saddle support rod, and the passive pulley is driven by an active pulley on an axle of a bottom bracket shell. When an exerciser steps on the pedal, the link rod drives the lower end of the saddle support rod up and down, so that the handle support rod at another end of the transversal rod can swing back and forth by using the lower end of the fixing bolt as a pivot. The exerciser not only can train both legs, but also can achieve the effect of shaking and massaging both hands and the whole body, so as to exercise the whole body.
