<p>The present invention relates to a spinning bicycle, which comprises a wheel frame (10) having a wheel (12) and a handle (13) mounted thereon; a middle frame (20) supporting the wheel frame (10); a saddle frame (30) connected to a saddle (31); a rotary shaft (30) connected to a sprocket (31); a chain (40) connecting the sprocket (31) and the wheel (12), a pair of pedal units (40) axis-rotating a rotary shaft (30); and a brake unit (50) for fixating the pedal units (40). Therefore, the pedal units in a cylinder mode allow to perform a pedal lever function with the cylinder per se so as to allow the axial rotation motion of pedals, and stand the erection state of the cylinder so as to allow the pedals to perform the reciprocal motion along the longitudinal direction of the cylinder. Accordingly, the spinning bicycle selectively performs a rotational motion axially rotating the wheel with the lower body of a user on the spot in the state that the bicycle is fixated to the ground, and a reciprocal motion vertically moving the lower body of the user on the pedals in the state of stopping the wheel, thereby allowing the user to perform various performances by a combined lower body exercise.</p> |
