EXERCISE BIKE Russian patent published in 2019 - IPC A63B69/16 A63B21/00 

FIELD: exercise machines.

SUBSTANCE: invention relates to simulators providing use of bicycles at any time of the year, incl. and in rooms. Exercise bike comprises frame simulator, front, middle and rear support rollers. Middle roller is kinematically connected with front roller pulley by flexible link, and pulley has kinematic connection with running surface of front roller via overrunning coupling. Running surfaces of rollers rotate on axles fixed to bicycle loader frame. To use a bicycle simulator with different physical capabilities, the flywheel is composite and typed. Safety of trainings with maximum peak loads on pedals is ensured by limiting roller of rear wheel longitudinal travel. Drive of front roller rotation from rear provides maximum permissible reduction of distance between middle and rear rollers.

EFFECT: in the version where the diameter of the pulleys of the driven roller is less than the diameter of the pulley of the driving roller and (or) the diameter of the running surface of the driven roller is more than the corresponding diameter of the driving roller, the front wheel rotates at a higher speed than the rear wheel, higher controllability of the bicycle at low speeds of pedaling.
