Abstract
A magnetic resistance upright bike includes a frame and a driving wheel and a fly wheel are connected to the frame wherein the fly wheel is driven by the driving wheel. A magnetic resistance device includes a support member fixed on the frame and a magnet assembly is connected on the support member. The magnet assembly includes two magnets supported on the support member and the fly wheel is rotatably located between the two magnets. A circuit board is electrically connected to the two magnets and a control device is connected to the circuit board. The gap between the fly wheel and the magnets are fixed and the magnetic force can be controlled by adjusting the current powering the magnets.
