1. An exercise bicycle frame comprising:
- a tube including a tube cross-section with one end of the tube cross-section including a dimension less than a dimension through a mid-section of the tube cross-section; and
a post including a post cross-section with one post end of the post cross-section including a dimension less than a dimension through a mid-section of the post cross-section;
wherein the post fits within the tube, with the one post end of the post cross-section adjacent the one end of the tube cross-section;
wherein the tube includes a pop pin; and
wherein the pop pin is adapted to apply force to the post to positively engage at least the one post end of the post cross-section with at least the one end of the tube cross-section.

Abstract
A unique structure for an indoor exercise bike that provides strength in its design, as well as the flexibility to create an aesthetically appealing frame structure. The monocoque frame design, including two symmetrical halves joined together, forms a very strong, light shell that can take on a variety of shapes and sizes. The seat structure, handlebar structure, drive train and support platforms are all able to be readily attached to the primary frame structure to provide an exercise bicycle that is sturdy, easy to manufacture, and light enough to easily move when necessary.

3. An exercise bicycle frame comprising:
-
a tube including a tube cross-section with one end of the tube cross-section including a dimension less than a dimension through a mid-section of the tube cross-section, the tube cross-section includes a dimension between the mid-section of the tube cross-section and the one end of the tube cross-section that diminishes in a direction toward the one end of the tube cross-section; and a post including a post cross-section with one post end of the post cross-section including a dimension less than a dimension through a mid-section of the post cross-section, the post cross-section including a dimension between the mid-section of the post cross-section and the one post end of the post cross-section that diminishes in a direction toward the one post end of the post cross-section; wherein the post fits within the tube, with the one post end of the post cross-section adjacent the one end of the tube cross-section and at least a portion of the diminishing dimension of the post cross-section adjacent at least a portion of the diminishing dimension of the tube cross-section; wherein the tube includes a pop pin; and wherein the pop pin is adapted to apply a force to the post to positively engage at least one of; a part of the diminishing dimension of the post cross-section with a part of the diminishing dimension of the tube cross-section; and the one post end of the post cross-section with the one end of the tube cross-section. - View Dependent Claims (4, 5, 6, 11, 12, 18, 19)

7. An exercise bicycle frame comprising:
-
a tube including a tube cross-section with one end of the tube cross-section including a dimension less than a dimension through a mid-section of the tube cross-section, the tube cross-section includes a dimension between the mid-section of the tube cross-section and the one end of the tube cross-section that diminishes in a direction toward the one end of the tube cross-section; and a post including a post cross-section and with one post end of the post cross-section including a dimension less than a dimension through a mid-section of the post cross-section, the post cross-section including a dimension between the mid-section and the one post end of the post cross-section that diminishes in a direction toward the one post end of the post cross-section; wherein a rate of diminishing of the dimension of the tube cross-section is substantially the same as a rate of diminishing of the dimension of the post cross-section; wherein the post fits within the tube, with the one post end of the post cross-section adjacent the one end of the tube cross-section, and the diminishing dimension of the post cross-section adjacent the diminishing dimension of the tube cross-section; wherein the tube includes a pop pin, the post defines a plurality of apertures, and the pop pin is adapted to engage one of the plurality of apertures in the post; and wherein the pop pin is adapted to apply a force to the post to positively engage at least one of; a part of the diminishing dimension of the post cross-section with a part of the diminishing dimension of the tube cross-section; and the one post end of the post cross-section with the one end of the tube cross-section. - View Dependent Claims (8, 9, 13, 14, 20, 21)
