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, a first resistance source and a second resistance source. The stand is adapted to support the bicycle. The roller is pivoted to the stand and is adapted to contact a bicycle wheel of the bicycle. The first resistance source is coupled to the roller and provides resistance to the bicycle wheel via the roller. The second resistance source is coupled to the roller and provides resistance to the bicycle wheel via the roller.

First claim

1 . 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; a first resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller; and a second resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the first resistance source is an automatic adjusting resistance source, and the second resistance source is a manual adjusting resistance source.

2 . The bicycle trainer as claimed in claim 1 , wherein the first resistance source is a wind resistance type resistance source, a magnetic resistance type resistance source, a fluid resistance type resistance source or a friction type resistance source.

3 . The bicycle trainer as claimed in claim 1 , wherein the second resistance source is a wind resistance type resistance source, a magnetic resistance type resistance source, a fluid resistance type resistance source or a friction type resistance source.

4 . (canceled)

5 . The bicycle trainer as claimed in claim 1 , wherein the first resistance source and the second resistance source are respectively located at two ends of the roller.

6 . The bicycle trainer as claimed in claim 1 , wherein the first resistance source, the second resistance source and the roller are coupled to the same rotation axis.

7 . The bicycle trainer as claimed in claim 1 , wherein the first 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; and 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 a 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.

8 . The bicycle trainer as claimed in claim 7 , wherein the first resistance source further comprises:
a restoring component restoring the non-magnetic metal rotating component with respect to the restrictive rotating component.

9 . The bicycle trainer as claimed in claim 7 , wherein the first resistance source further comprises:
an inner cover fixed to the stand, wherein the magnetic fixing component is fixed to the inner cover; and an outer cover fixed to the restrictive rotating component.

10 . The bicycle trainer as claimed in claim 1 , wherein the second resistance source comprises:
a magnetism adjusting component movably attached to the stand; a non-magnetic metal rotating component coupled to the roller and mutually interacting with the magnetism adjusting component to produce a magnetic resistance; and an adjustment assembly connected to the magnetism adjusting component, used to adjust the interacting area between the magnetism adjusting component and the non-magnetic metal rotating component.

11 . The bicycle trainer as claimed in claim 10 , wherein the resistance source further comprises:
an inner cover fixed to the stand, wherein the magnetism adjusting component is movably coupled to the inner cover; and an outer cover fixed to the non-magnetic metal rotating component.

12 . 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; a first resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the first 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; and 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 a 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; and a second resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller.

13 . The bicycle trainer as claimed in claim 12 , wherein the second resistance source is a wind resistance type resistance source, a magnetic resistance type resistance source, a fluid resistance type resistance source or a friction type resistance source.

14 . The bicycle trainer as claimed in claim 12 , wherein the first resistance source, the second resistance source and the roller are coupled to the same rotation axis, and the first resistance source and the second resistance source are respectively located at two ends of the roller.

15 . The bicycle trainer as claimed in claim 12 , wherein the first resistance source further comprises:
a restoring component restoring the non-magnetic metal rotating component with respect to the restrictive rotating component.

16 . The bicycle trainer as claimed in claim 12 , wherein the first resistance source further comprises:
an inner cover fixed to the stand, wherein the magnetic fixing component is fixed to the inner cover; and an outer cover fixed to the restrictive rotating component.

17 . 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; a first resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller; and a second resistance source coupled to the roller and providing resistance to the bicycle wheel via the roller, wherein the second resistance source comprises: a magnetism adjusting component movably attached to the stand; a non-magnetic metal rotating component coupled to the roller and mutually interacting with the magnetism adjusting component to produce a magnetic resistance; and an adjustment assembly connected to the magnetism adjusting component, used to adjust the interacting area between the magnetism adjusting component and the non-magnetic metal rotating component.

18 . The bicycle trainer as claimed in claim 17 , wherein the first resistance source is a wind resistance type resistance source, a magnetic resistance type resistance source, a fluid resistance type resistance source or a friction type resistance source.

19 . The bicycle trainer as claimed in claim 17 , wherein the first resistance source, the second resistance source and the roller are coupled to the same rotation axis, and the first resistance source and the second resistance source are respectively located at two ends of the roller.
