The invention discloses a spinning and relates to the field of fitness equipment. The spinning comprises a spinning body and an air purification device, the spinning body comprises a handrail bracket, a saddle bracket and a fly wheel, the air purification device is arranged at the handrail bracket, the air purification device comprises a coupling, a coupling shaft, a filter screen, a wind barrel and at least one wind wheel, one end of the coupling shaft is located at the bottom of the inner cavity of the wind barrel, each of the wind wheel and coupling sleeves the coupling shaft, each wind wheel is located in the wind barrel, the coupling is located at the outside of the wind barrel, the fly wheel is in transmission connection with the coupling through friction, and the filter screen is firmly connected with the inner wall of the wind barrel. The spinning converts the mechanical energy generated by the acting of a sporter on the spinning in the exercise process into the wind energy for the rotation of the wind wheel of the air purification device, the effective use for the output power of the spinning is realized, and the spinning is featured with energy saving, environment friendliness and various function.
