Lightweight bicycle seat assemblies
A bicycle seat apparatus including at least one rail and a saddle shell. The at least one rail can include a first mounting portion. The first mounting portion can include an ankle. A cross section of a terminus of the ankle can be larger than a cross section of the at least one rail. The saddle shell can include at least one mounting cup configured to mate with the first mounting portion of the at least one rail. A cross section of a base of the at least one mounting cup can be larger than a cross section of the terminus of the ankle.
1. A bicycle seat apparatus, comprising:
at least one rail including a first mounting portion comprising an ankle, wherein a cross section of a terminus of the ankle is larger than a cross section of the at least one rail;
a saddle shell including at least one mounting cup configured to mate with the first mounting portion of the at least one rail, wherein a cross section of a base of the at least one mounting cup is larger than a cross section of the terminus of the ankle; and
a saddle cover comprising:
a first layer comprising thermoplastic polyurethane;
a second layer comprising a mesh including a plurality of openings; and
a third layer comprising thermoplastic polyurethane;
such that a plurality of portions of the first layer of thermoplastic polyurethane are fused directly to the third layer of thermoplastic polyurethane, and such that at least a portion of the first layer and at least a portion of the third layer are fused directly to the second layer of mesh so that the second layer of mesh is fused between the first layer of thermoplastic polyurethane and the third layer of thermoplastic polyurethane to allow gas to escape.
2. The apparatus of claim 1 , wherein the first mounting portion intersects the saddle shell at an angle greater than 15 degrees.
3. The apparatus of claim 1 , wherein the first mounting portion intersects the saddle shell at an angle greater than 20 degrees.
4. The apparatus of claim 1 , wherein the first mounting portion intersects the saddle shell at an angle in a range from about 15 degrees to about 45 degrees.
5. The apparatus of claim 1 , wherein the first mounting portion intersects the saddle shell at an angle in a range from about 15 degrees to about 55 degrees.
6. The apparatus of claim 1 , wherein the first mounting portion is bonded to the at least one mounting cup.
7. The apparatus of claim 1 , wherein first mounting portion includes a tab and the at least one mounting cup includes a notch configured to mate with the tab.
8. The apparatus of claim 1 , wherein the at least one mounting cup includes an indexing feature configured to mate with the first mounting portion to prevent rotation of the first mounting portion.
9. A bicycle seat apparatus, comprising:
a saddle shell covered at least in part by a deformable material; and
a saddle cover covering at least a portion of the deformable material including:
a first layer comprising thermoplastic polyurethane;
a second layer comprising a mesh including a plurality of openings; and
a third layer comprising thermoplastic polyurethane;
such that a plurality of portions of the first layer of thermoplastic polyurethane are fused directly to the third layer of thermoplastic polyurethane, and such that at least a portion of the first layer and at least a portion of the third layer are fused directly to the second layer of mesh so that the second layer of mesh is fused between the first layer of thermoplastic polyurethane and the third layer of thermoplastic polyurethane to allow gas to escape.
10. The apparatus of claim 9 , wherein the deformable material comprises foam.
11. The apparatus of claim 9 , wherein the first layer covers at least a portion of the deformable material.
12. The apparatus of claim 11 , wherein the third layer encapsulates the second layer, the first layer, and the deformable material.
13. The apparatus of claim 11 , wherein the third layer is clear.
14. A method, comprising:
fusing a saddle cover together including:
a first layer comprising thermoplastic polyurethane;
a second layer including a mesh comprising a plurality of openings; and
a third layer including thermoplastic polyurethane; and
coupling the saddle cover to a saddle;
such that a plurality of portions of the first layer of thermoplastic polyurethane are fused directly to the third layer of thermoplastic polyurethane, and such that at least a portion of the first layer and at least a portion of the third layer are fused directly to the second layer of mesh so that the second layer of mesh is fused between the first layer of thermoplastic polyurethane and the third layer of thermoplastic polyurethane to allow gas to escape.
15. The method of claim 14 , wherein the saddle cover further comprises a substrate.
16. The method of claim 14 , wherein the third layer is clear.
17. The method of claim 14 , wherein the second layer is configured to allow gas to escape during fusing the saddle cover together.
18. The method of claim 14 , wherein coupling the saddle cover to a saddle comprises fusing the saddle cover to the saddle.
19. The method of claim 18 , wherein the substrate is a woven fabric.
