Abstract

A split handlebar assembly for an aerodynamic bicycle having a handlebar stem for attaching said split handlebar assembly, comprising a right handlebar and a left handlebar; the right handlebar having a mounting section at one end, and a right grip section at the other end; the left handlebar having a mounting section at one end, and a left grip section at the other end; the right handlebar mounting section being configured to engage with the left handlebar mounting section; and the engaged mounting sections being configured to secure the right handlebar and the left handlebar to the handlebar stem.

Claims

1. A split handlebar assembly for an aerodynamic bicycle, comprising:

a right handlebar having a mounting section at one end;

a left handlebar having a mounting section at one end;

wherein an overlapping section of the right handlebar mounting section is configured to overlap and engage with an overlapping section of the left handlebar mounting section to form a half lap splice joint; and

wherein the engaged mounting sections are configured to secure the right handlebar and the left handlebar to each other and to a handlebar stem.

2. The split handlebar assembly of claim 1, wherein the right handlebar mounting section includes a mounting plate having one or more mounting holes, the left handlebar mounting section includes a mounting plate having one or more mounting holes, and the mounting holes are configured to align with mounting sockets in a stem plate secured to the handlebar stem.

3. The split handlebar assembly of claim 2, wherein one or more of the mounting holes of the right handlebar are configured to align with one or more of the mounting holes of the left handlebar when positioned in a mounting position on the stem plate.

4. The bicycle of claim 1, further comprising a stem plate coupling a fork steerer to the bicycle frame, and a base plate cover configured to couple the handlebar mounting sections to the stem plate in a structural sandwich configuration.

5. The split handlebar assembly of claim 1, wherein the right handlebar is configured to be mounted to the handlebar stem in a flipped over position, and the left handlebar is configured to be mounted to the handlebar stem in a flipped over position, thereby forming a bars up setup.

6. The split handlebar assembly of claim 5, wherein the right handlebar mounting section includes a mounting plate having one or more mounting holes, the left handlebar mounting section includes a mounting plate having one or more mounting holes, and the mounting holes are configured to align with mounting sockets in a stem plate secured to the handlebar stem with a base plate cover.

7. The split handlebar assembly of claim 6, wherein one or more of the mounting holes of the right handlebar are configured to align with one or more of the mounting holes in the left handlebar when positioned in a mounting position on the stem plate.

8. The split handlebar assembly of claim 1, wherein the right handlebar includes a conduit for running a bicycle component cable, the left handlebar includes a conduit for running a bicycle component cable, and the cables are configured to keep the right handlebar and the left handlebar attached to the bicycle when detached from the handlebar stem.

9. A bicycle frame comprising:

a fork assembly;

a bottom bracket;

a top tube, a head tube, a seat tube and a down tube, wherein one end of the top tube and one end of the down tube are affixed to the head tube, another end of the top tube is affixed to the seat tube, and the fork assembly is operatively coupled to the head tube;

first and second chain stays, wherein one end of each of the chain stays is affixed to the bottom bracket; and

a split handlebar assembly including;

a right handlebar having a mounting section at one end;

a left handlebar having a mounting section at one end;

wherein an overlapping section of the right handlebar mounting section is configured to overlap and engage with an overlapping section of the left handlebar mounting section to form a half lap splice joint; and

wherein the engaged mounting sections are configured to secure the right handlebar and the left handlebar to each other and to a handlebar stem.

10. The bicycle frame of claim 9, wherein the mounting section for the right handlebar comprises a mounting plate having one or more mounting holes, the mounting section for the left handlebar comprises a mounting plate having one or more mounting holes, and the mounting holes are configured to align with mounting sockets in a stem plate secured to the handlebar stem.

11. The bicycle frame of claim 10, wherein one or more of the mounting holes in the right handlebar are configured to align with one or more of the mounting holes in the left handlebar when positioned in a mounting position on the stem plate.

12. The bicycle frame of claim 9, wherein the right handlebar is configured to be mounted to the handlebar stem in a flipped over position, the left handlebar is configured to be mounted to the handlebar stem in a flipped over position, and in the flipped over position, the right handlebar and the left handlebar form a bars up setup.

13. The bicycle frame of claim 12, wherein the mounting section for the right handlebar comprises a mounting plate having one or more mounting holes, the mounting section for the left handlebar comprises a mounting plate having one or more mounting holes, and the mounting holes are configured to align with mounting sockets in a stem plate secured to the handlebar stem with a base plate cover.

14. The bicycle frame of claim 13, wherein one or more of the mounting holes in the right handlebar are configured to align with one or more of the mounting holes in the left handlebar when positioned in a mounting position on the stem plate.

15. The bicycle frame of claim 9, wherein the right handlebar includes a conduit for running a bicycle component cable, the left handlebar includes a conduit for running a bicycle component cable, and the cables are configured to keep the right handlebar and the left handlebar attached to the bicycle frame when detached from the handlebar stem.

16. The bicycle frame of claim 9, further comprising a stem plate configured to couple a fork steerer to the bicycle frame, and a base plate cover configured to couple the handlebar mounting sections to the stem plate in a structural sandwich configuration.

17. A bicycle comprising:

a bicycle frame including;

a fork assembly;

a bottom bracket;

a top tube, a head tube, a seat tube and a down tube;

first and second chain stays;

a front wheel;

a rear wheel; and

a split handlebar assembly including;

a right handlebar having a mounting section at one end;

a left handlebar having a mounting section at one end;

wherein an overlapping section of the right handlebar mounting section is configured to overlap and engage with an overlapping section of the left handlebar mounting section to form a half lap splice joint; and

wherein the engaged mounting sections are configured to secure the right handlebar and the left handlebar to each other and to a handlebar stem.

18. The split handlebar assembly of claim 17, further comprising a stem plate configured to couple a fork steerer to the bicycle frame, and a base plate cover configured to couple the handlebar mounting sections to the stem plate in a structural sandwich configuration.

19. The bicycle of claim 17, wherein the right handlebar is configured to be mounted to the handlebar stem in a flipped over position, the left handlebar is configured to be mounted to the handlebar stem in a flipped over position, and in the flipped over position, the right handlebar and the left handlebar form a bars up setup.

20. The bicycle of claim 17, wherein the right handlebar mounting section includes one or more mounting holes, the left handlebar mounting section includes one or more mounting holes, and the mounting holes are configured to align with mounting sockets in a stem plate secured to the handlebar stem with a base plate cover.
