Abstract
A bicycle trainer is adapted to be arranged with a bicycle to simulate riding a bicycle on an outdoor road. The bicycle includes a stand, a roller and a resistance source. The stand is adapted to support the bicycle. The roller is pivoted to the stand and adapted to contact a bicycle wheel of the bicycle. The resistance source is coupled to the roller and provides resistance to the bicycle wheel via the roller. The resistance source varies the magnitude of the provided resistance according to the rotation speed of the roller.

A bicycle trainer, adapted to be arranged with a bicycle to simulate riding a bicycle on an outdoor road, the bicycle trainer comprising:
- a stand adapted to support the bicycle;
- a roller pivoted to the stand and adapted to contact a bicycle wheel of the bicycle;
- and
- a resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the resistance source varies the magnitude of the provided resistance according to a rotation speed of the roller and provides a speed power curve having a plurality of stages.
A bicycle trainer, adapted to be arranged with a bicycle to simulate riding a bicycle on an outdoor road, the bicycle trainer comprising:
- a stand adapted to support the bicycle;
- a roller pivoted to the stand and adapted to contact a bicycle wheel of the bicycle;
- and
- a resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the resistance source varies the magnitude of the provided resistance according to a rotation speed of the roller, and the resistance source comprises:
- a magnetic fixing component fixed to the stand;
- a non-magnetic metal rotating component coupled to the roller and mutually interacting with the magnetic fixing component producing a magnetic resistance;
- a restrictive rotating component coupled to the roller;
- and
- a restoring component exerting a restoring force to the non-magnetic metal rotating component with respect to the magnetic fixing component, and varying the magnitude of the restoring force exerted according to the change in a rotation speed of the roller.

- a resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the resistance source varies the magnitude of the provided resistance according to a rotation speed of the roller, and the resistance source comprises:
- a magnetic fixing component fixed to the stand;
- a non-magnetic metal rotating component coupled to the roller and mutually interacting with the magnetic fixing component to produce a magnetic resistance;
- a restrictive rotating component coupled to the roller and construing a plurality of paths with the non-magnetic metal rotating component;
- a plurality of rolling components respectively located in the plurality of paths and respectively moving along the plurality of paths due to the influence of centrifugal force, allowing the non-magnetic metal rotating component to move with respect to the restrictive rotating component to adjust an interacting distance between the magnetic fixing component and the non-magnetic metal rotating component, wherein a change in curvature of the plurality of paths correspond with a change in the magnetic resistance produced by a mutual interaction between the non-magnetic metal rotating component and the magnetic fixing component.
