Generally, the structure of an inertial wheel is to separately install a rotating wheel and a flywheel on a fixed frame. The rotating wheel and the flywheel are connected by transmission. Both ends of the main rotating wheel are respectively connected to a crank. The movement of the crank drives the main rotating wheel to rotate, and then the main rotating wheel drives the flywheel to rotate through a transmission mechanism such as a chain or a belt, and adjusts the exercise intensity by adjusting the flywheel resistance to adapt to different riders or produce different usage effects. However, the inertial wheel for a fitness apparatus in the prior art is usually of a disc structure and is made into a wheel body structure by casting. Then, an aluminum sheet is coated on the periphery of the wheel body structure. This structure of the inertial wheel mainly has the disadvantages of large mechanical processing amount, cumbersome production, and high production cost. Summary of the Utility Model
