Abstract
The present disclosure relates to a stationary exercise apparatus for indoor cycle training (1), i.e. a stationary exercise bicycle, preferably provided with a magnetic resistance unit (15). One embodiment relates to a stationary exercise bike comprising a flywheel (10) defining a radial gap (25) in the periphery wherein at least the periphery of the flywheel (10) has ferromagnetic properties, and wherein a magnetic resistance unit (15) is configured to controllably insert one, two or more magnets into said radial gap.
Claims20
A stationary exercise bike comprising:
- a lower frame housing a flywheel drivable by a rotatable crankshaft, wherein the flywheel comprises two parallel plates mounted in parallel on a flywheel shaft with a distance there between thereby forming a radial gap, and wherein each parallel plate comprises one or more rings mounted near a periphery of the parallel plates, and wherein the one or more rings have at least one of conductive or ferromagnetic properties.
A stationary exercise bike comprising:
- a lower frame housing a flywheel drivable by a rotatable crankshaft, the flywheel having a radial gap between outer surfaces of the flywheel, wherein at least a periphery of the flywheel has conductive or ferromagnetic properties, and wherein a magnetic resistance unit is configured to controllably insert one or more magnets into the radial gap, wherein the magnetic resistance unit comprises a stepper motor, a threaded guide bolt, a slide seat, and a magnet holder for holding the one or more magnets, such that the magnet holder can be translated inside the radial gap of the flywheel in a linear fashion.
