Stationary bike comprising cylindrical elastic feet

A stationary bike comprising a main frame, the main frame having a base for standing the main frame on the ground, the base having an end surface facing the ground, the end surface being equipped with a plurality of elastic feet that are spaced and arranged symmetrically, each elastic foot being made of a soft, elastic material and formed as a hollow member, each elastic foot containing therein an inner space defined by a circular wall circling therearound, the base having protrusions extending downward, each protrusion positionally corresponding to one of said plurality of elastic feet, each protrusion being provided with a positioning hole, each elastic foot having a top end configured to connect to the corresponding protrusion of the base and a bottom end configured to press on the ground, an assembling hole formed at the top end of each elastic foot for receiving the corresponding protrusion, one end of a positioning member entering the assembling hole of each elastic foot from below through the inner space of said elastic foot and being retained in the positioning hole of the corresponding protrusion,

• wherein the assembling hole of each elastic foot has a depth greater than a height of the corresponding protrusion, the protrusion and a bottom of the assembling hole thereby, forming a buffering space upon receipt of the protrusion, and
• wherein, when each elastic foot receives an external force from the base, the circular wall deforms correspondingly, thereby jolting the main frame to provide simulation of road-riding experience.
