摘要： A magnetic resistive device that is suitable for use with a bicycle trainer including a rotatable shaft having a magnetic resistive force member engaged to an end thereof. In the preferred embodiment the magnetic resistive force member includes a cylindrical outer surface. A plurality of magnets are disposed on one side of said magnetic resistive force member, preferably in alternating polarity. Magnetic fields generated between adjacent magnets create eddy currents within the magnetic resistive force member to create a resistive force against the rotation of the magnetic resistive force member. In the preferred embodiment, the magnets are disposed outside of the cylindrical magnetic resistive force member, and the magnets are movable away from the magnetic resistive force member to reduce the force induced therewithin.
