Bike saddle structure in which the oscillation angle and height of a bike saddle are adjustable, and exercise bicycle comprising same

The present invention relates to a bike saddle structure in which the oscillation angle and height of a bike saddle are adjustable, and to an exercise bicycle comprising same. Vibrations in the bike saddle are minimized and the stability thereof is ensured during the left and right oscillation of the bike saddle, thus enabling a rider to exercise his/her whole body including the legs, pelvis, spine, abdomen, etc. over a long period of time. The forward and backward direction and height of the bike saddle are adjustable by the rider, thus providing a wide range of exercise.
