ABSTRACT:
A damping device for an exercising cycle includes a support base, and a damping unit. The damping unit includes a contact wheel rotatably mounted on the support base, a flywheel mounted on the first end of the shaft of the contact wheel, and a stirring wheel mounted on the second end of the shaft of the contact wheel and mounted in a container which contains hydraulic oil therein. Thus, the contact wheel is rotated by the rear wheel to rotate the shaft which rotates the flywheel, so that the blades of the flywheel are rotated to produce an air flow which is used to cool the heat produced by the friction between the contact wheel and the rear wheel, and to cool the hydraulic oil contained in the container.
