An exerciser driving mechanism generally comprising a driving wheel, a timing belt, a tension wheel, a free wheel, a flywheel, and a wool felt, with which the feeling of "inoperative pedaling" likely happened to the free wheel as experienced in the prior art exerciser upon instantaneously actuating the belt may be eliminated, the gear ratio of driving wheel to free wheel is increased, the contact area of the wool felt with the flywheel is reduced to enhance the speed of inertial rotation in regard to the flywheel, while maintaining the desired friction drag efficiency, thus resulting in an excellent smooth operation.
