Abstract: Disclosed herein are a mode switching system and an exercise bike comprising the same that switches a non-freewheel mode and a freewheel mode automatically, ensuring improvement in user convenience. The exercise bike comprise a step motor, a first limit sensor sensing a first part of the face gear and outputting a first sensing signal, a second limit sensor sensing a second part of the face gear and outputting a second sensing signal, and a controller determining a current power transfer mode by using the first sensing signal and the second sensing signal, and rotating the step motor forward or reversely, based on the current power transfer mode, to switch the power transfer mode to the non-freewheel mode or the freewheel mode, in a case where a mode switching signal is input.

Abstract: The present invention discloses a fitness bike and a method of controlling the same. The fitness bike according to the present invention includes an operation lever configured to restrict a clutch gear unit to a flywheel to allow the flywheel to operate in a non-freewheel mode and release the restriction between the clutch gear unit and the flywheel to allow the flywheel to operate in a freewheel mode, a position detection unit installed on the flywheel to detect a rotation position of the operation lever, and a controller configured to brake the flywheel by adjusting a magnitude of a magnetic force of a stator so that the operation lever stops at a preset exposure position when a pedal is stopped.
