Abstract: Disclosed are various embodiments directed toward applying a magnetic resistance to a human powered vehicle during movement. In various embodiments, magnets are placed within receptacles of magnet holding brackets and are exposed to one or more conducting discs that are configured to spin with the wheels of the human powered vehicle. The magnetic field of the magnets that intersect the conducting discs can generate a force that opposes the movement of the human powered vehicle. In various embodiments, the magnet holding brackets are adjustable based on desired wattage values.
