Dual-purpose exercise equipment

Abstract

A dual-purpose exercise equipment includes a spin bike, a bicycle after removal of a rear wheel thereof, and a linking device arranged at one side of an axle of a flywheel of the spin bike and coupled with the bicycle. Thus, an individual user can selectively ride the spin bike or bicycle of the dual-purpose exercise equipment. Alternatively, two users can ride the spin bike and the bicycle respectively at the same time, enjoying riding a tandem bicycle.

What is claimed is: 
     
         1 . A dual-purpose exercise equipment, comprising:
 a spin bike comprising a bike frame, a saddle, a handlebars and a flywheel; and   a bicycle after removal of a rear wheel thereof;   wherein:   a linking device is arranged on an axle of said flywheel of said spin bike and coupled with a chain of said bicycle for virtual riding as well as physical riding.   
     
     
         2 . The dual-purpose exercise equipment as claimed in  claim 1 , wherein said linking device is a speed-change gear. 
     
     
         3 . The dual-purpose exercise equipment as claimed in  claim 2 , wherein said speed-change gear comprises a gear cluster and a hub. 
     
     
         4 . The dual-purpose exercise equipment as claimed in  claim 2 , wherein said speed-change gear mounted at said bike frame corresponding to said flywheel in a coaxial manner relative to the axle of said flywheel for synchronous rotation with said flywheel subject to an external pedaling force.
