  • Patent number: 11141619
    Abstract: A spinner bike with adjustable magnetic resistance includes a generator, a disc plate, a magnetic resistance adjusting apparatus and a resistance adjusting apparatus. The elements are disposed on a frame body of a spinner bike, so that a pedaling mechanism of the spinner bike can be operated to drive a flywheel and the disc plate for generating electricity by the cutting of flux formed by a plurality of magnets surrounding an armature core. Rotating a button of the resistance adjusting apparatus enables a connecting rod operating a pulling cable, so as to further alter coverage of the flux on the disc plate for adjustment of the loading resistance.
    Type: Grant
