Exercise bicycle frame with bicycle seat and handlebar adjustment assemblies

1. An exercise bicycle comprising:

an exercise bicycle frame including:

a down tube extending angularly and upwardly from a rear portion to a front portion;

a seat tube extending upwardly and rearwardly from the rear portion of the down tube;

a fork assembly extending from a position rearward of the front portion of the down tube and a head tube to a front support member; and

the head tube coupled with the front portion of the down tube, the head tube supporting a handlebar assembly translationally supporting a handlebar such that the handlebar may be adjusted fore and aft between positions rearward relative to the head tube.

2. The exercise bicycle of claim 1 further comprising a handlebar operably coupled with the handlebar assembly on a rearward portion of the handlebar assembly, the handlebar assembly comprising:

a first tube comprising an elongate aperture; a second tube positioned within the elongate aperture of the first tube, the second tube defining a channel receiving a member moveable within the channel, the member defining an engagement surface; and a handle operably coupled with the member to move the member within the channel in a first direction or a second direction.

3. The exercise bicycle of claim 1 wherein the handlebar assembly comprises a first receiver comprising a first elongate aperture; a first slider positioned within the first elongate aperture of the first receiver, the first slider defining a first channel receiving a first member moveable within the first channel, the first member defining a first engagement surface; and a first handle operably coupled with the first member to move the first member within the first channel in a first direction or a second direction such that the first engagement surface causes a first coupling between the first slider and the first receiver when the first slider is moved in the first direction and releases the second coupling when the first slider is moved in the second direction.

4. The exercise bicycle of claim 3 further comprising an adjustable seat assembly adjustably supported by the seat tube, the adjustable seat assembly including a seat and comprising:

a second receiver comprising a second elongate aperture;

a second slider positioned within the second elongate aperture of the second receiver, the second slider defining a second channel receiving a second member moveable within the second channel, the second member defining a second engagement surface; and

a second handle operably coupled with the second member to move the first member within the first channel in a first direction or a second direction such that the first engagement surface causes a second coupling between the second slider and the second receiver when the second slider is moved in the second direction and releases the second coupling when the second slider is moved in the second direction.

5. The exercise bicycle of claim 4 wherein a separation between the adjustable seat assembly and the handlebar assembly is in a range of about 527 millimeters to about 627 millimeters.

6. The exercise bicycle of claim 1 wherein the fork assembly includes a first fork that includes a first bracket defining a first channel with a first opening for receiving and supporting an axle of a flywheel, and a second fork that includes a second bracket defining a second channel with a second opening for receiving and supporting the axle of the flywheel, the first and second openings facing forwardly relative to the exercise bicycle.

7. The exercise bicycle of claim 6 wherein the first and second channels are orientated transverse to the respective first and second forks such that the axle is gravitationally biased away from the respective first and second openings.

8. The exercise bicycle of claim 6 wherein the flywheel has a radius of about 430 millimeters.

9. The exercise bicycle of claim 6 further comprising a crank assembly supported by the down tube and including a drive sprocket including between 70 and 74 teeth; a flywheel sprocket coupled with the flywheel, the flywheel sprocket including between 13 and 17 teeth; and a chain interconnecting the drive sprocket with the flywheel sprocket.

10. The exercise bicycle of claim 9 wherein the down tube is orientated at an angle of between 40 and 44 degrees and the seat tube is angled rearwardly at an angle of between 70 and 74 degrees.

11. The exercise bicycle of claim 10 further comprising a gusset positioned at an intersection between the down tube and the seat tube, the gusset defining a step of about 254 millimeters.

12. The exercise bicycle of claim 11 wherein the fork assembly is coupled with the down tube between 310 and 320 millimeters above the gusset and the head tube is coupled with the down tube between 555 and 565 millimeters above the gusset.

13. The exercise bicycle of claim 1 further comprising a brace extending rearwardly from the rear portion of the down tube and extending forwardly to a front support member.

14. The exercise bicycle of claim 13 wherein the brace comprises a first section extending forwardly and downwardly from an area adjacent an intersection between the down tube and the seat tube, the brace further comprising a second section extending rearwardly and downwardly from the intersection.

15. An exercise bicycle frame comprising:

a down tube extending angularly and upwardly from a rear portion to a front portion;

a seat tube extending upwardly and rearwardly from the rear portion of the down tube;

a fork assembly extending from a position rearward of the front portion of the down tube to a front support member;

a head tube coupled with the front portion of the down tube; and

means for adjustably supporting a handlebar coupled with the head tube.

16. The exercise bicycle frame of claim 15 further comprising means for adjustably supporting a seat coupled with the seat tube.

17. The exercise bicycle of claim 1 wherein the head tube is positioned at a substantially vertical position.
