The stator 180 is an electromagnet with a coil 182 wound around an iron core 181. As power is applied to the coil 182, magnetic force is generated in the stator 180. The magnetic force strength of the stator 180 can be adjusted by adjusting the current applied to the coil 182 of the stator 180.

As the rotational load (magnetic force strength of the stator 180) of the flywheel 170 increases, the pedaling force for stepping on the pedal 130 increases, and the rotational load (magnetic force strength of the stator 180) of the flywheel 170 decreases. As time increases, the pressing force of the pedal 130 decreases. Accordingly, the rotational load of the flywheel 170 can be adjusted by adjusting the magnetic force strength of the stator 180, thereby controlling the user's walking force.

Meanwhile, in the exercise bike 1 according to the second embodiment of the present invention, the flywheel 170 may be arranged on the rear side or on the front side with respect to the drive shaft portion 133.
