ABSTRACT:
A magnetic resistance control apparatus for an exercise bicycle including a bicycle frame having a fork structure extending therefrom, a wheel having a magnetic surface thereon rotatably mounted on an axle within the fork structure, a pedal assembly rotatably connected to the bicycle frame and linked to the wheel such that a rotation of the pedal assembly causes a rotation of the wheel, a suspension arm connected to the fork structure and extending outwardly therefrom so as to have an end positioned beyond an outer diameter of the wheel, a suspension bar connected to the bicycle frame and extending therefrom so as to be positioned above an outer diameter of the wheel, an arc-shaped seat having magnets received on an interior surface thereof, extending around a portion of the wheel such that the magnets face the magnetic surface of the wheel, and a non-magnetic layer extending directly over the magnets of the seat so as to be interposed between the magnets and the wheel. The seat has an end pivotally connected to the end of the suspension arm. The seat is adjustably connected to the suspension bar so as to set a distance of the magnets from the wheel.
