Abstract: An exercise bike flywheel system includes a rotating shaft, a flywheel, one or more brake components, a bracket, first and second magnet components, first and second links, first and second gears and a driving device set. By driving the movement of the first magnet component and the second magnet component respectively through the first link and the second link, it avoids the situation of using a steel cable to pull the magnet component to the extreme position and getting stuck, thereby avoiding the generation of noise and motor burnout. If there is a program failure in the upper control instrument, you only need to adjust the program.

Abstract: A flywheel power generation system and an exercise bike are disclosed. The flywheel power generation system includes a rotating shaft, a flywheel, a bracket, a stator coil, a first brake member, a second brake member and a driving device set. The driving device set drives a first movable end and a second movable end toward or away from each other to adjust the gap between the first brake member/second brake member and the magnet set, thereby adjusting the riding resistance. When the flywheel rotates, the magnet set passes through the stator coil to cut the magnetic field to generate electromotive force so as to form an induced current, that is, to generate electrical energy. The resistance adjustment mechanism and the power generation mechanism in the flywheel power generation structure share the same magnet set, making the flywheel power generation system compact and low-cost.

Abstract: A power generating device includes a power generating unit and a frame, wherein the power generating unit is connected to the frame by two outer casings with two respective arms. The power generating unit has an input shaft and a roller is mounted to the input shaft. The frame is connected to the exerciser and a shock-absorbing member is located beneath the frame. Two resilient members are connected to two ends of the frame and two ends of each resilient member are respectively connected to the frame and the power generating unit so as to urge the roller to contact against the energy transferring end. The shock-absorbing member absorbs vibration from the power generating unit. The users operate the exerciser and generate electric power.

Abstract: A display for an exercise device has a cylindrical housing formed from a rear half shell and a front half shell. The housing has an inner space and two open ends, and a support rod of the body-build can pass through the inner space and extend out from the open ends. A positioning hole is defined in the support rod, and a positioning stub corresponding to the positioning hole is formed in the inner space of the housing. The positioning stub is mounted in the positioning hole to prevent the housing from rotating on the support rod. Two fasteners are securely and respectively formed on the housing in the inner space fasten the rear and front half shell together to form the housing.
