Abstract

A bicycle handlebar system that ensures comfort, safety, increasing center of gravity control. An ergonomic bicycle handlebar system including a hood having: a hood sweep angle from a top bar hood to a first portion of a drop, a drop angle from the first portion of a drop to the second portion of a drop, a thumb index; and a palm flat segment. The coefficient ergonomic bicycle handlebar may be made of nano tube zlyte resin with graphene impregnated carbon fibers.

Claims (43)

1. A coefficient ergonomic bicycle handlebar system comprising:

a) a hood comprising:

i) a top bar hood comprising:

(1) exactly two mirror-imaged top bars;

(2) wherein each of said exactly two mirror-imaged top bars is structured and arranged for structurally mounting to a bicycle stem;

(3) wherein said exactly two mirror-imaged top bars comprise a single top bar structural member;

ii) exactly two drops comprising:

(1) a first portion of each of said exactly two drops; and

(2) a second portion of each of said exactly two drops;

(3) wherein said first portion of each of said exactly two drops and said second portion of each of said exactly two drops are structured and arranged as a single top bar hood structural member with each of said exactly two mirror-imaged top bars;

iii) a hood sweep angle defined as an included sweep angle between said top bar hood and said first portion of said exactly two drops; and

iv) a drop angle defined as an included angle between said first portion of each of said exactly two drops and said second portion of each of said exactly two drops;

(1) wherein said sweep angle is greater than said drop angle;

(2) wherein said sweep angle is an acute angle;

b) exactly two palm flat segments, each of said exactly two palm flat segments comprising:

i) a straight length of said handlebar segment that is structured and arranged adjacent to a lowest handlebar segment;

ii) wherein each said straight length of said handlebar segment is structured and arranged for a rider to grasp each said straight length of said handlebar segment; and

c) exactly two thumb indices:

i) wherein each of said exactly two thumb indices comprise a longer thumb index dimension and a shorter thumb index dimension, which together define a thumb index flat surface, and which define each of said exactly two thumb indices;

ii) wherein said longer thumb index dimension that is structured and arranged parallel to a vertical handlebar segment when mounted on the bicycle stem;

iii) wherein said shorter thumb index dimension length that is structured and arranged perpendicular to said vertical handlebar segment;

iv) wherein each of said thumb index flat surface is angled at a mirrored angle relative to the bicycle stem; and

v) wherein said mirrored angle of each said thumb index flat surface comprises approximately ninety degrees.

2. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said coefficient ergonomic bicycle handlebar comprises nano tube zlyte resin with Graphene impregnated carbon fibers.

3. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said hood sweep angle is less than 45 degrees.

4. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said hood sweep angle is 12.5 degrees.

5. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said drop angle is less than 30 degrees.

6. The coefficient ergonomic bicycle handlebar system of claim 3 wherein said drop angle is 26.5 degrees.

7. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said longer thumb index dimension of said exactly two palm flat segments is greater than 100 mm.

8. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said shorter thumb index dimension of said exactly two palm flat segments is greater than 20 mm.

9. The coefficient ergonomic bicycle handlebar system of claim 1 wherein combination of said hood sweep angle and said drop angle create a camera angle for viewing traffic behind a rider.

10. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said combination of said hood sweep angle and said drop angle create a camera angle for viewing a road below and behind a rider.

11. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said mirrored angle of each thumb index flat surface is ninety degrees.

12. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said mirrored angle of each thumb index flat surface is 70 degrees.

13. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said thumb index flat surface comprises an area less than 5 square cm.

14. The coefficient ergonomic bicycle handlebar system of claim 1 wherein each said exactly two palm flat segments provides a flat surface for rider gripping of said coefficient bar ergonomic bicycle handlebar.

15. The coefficient ergonomic bicycle handlebar system of claim 1 wherein each said exactly two palm flat segments provides a flat surface comprising a raised-surface texturing for rider gripping of said coefficient bar ergonomic bicycle handlebar.

16. The coefficient ergonomic bicycle handlebar system of claim 1 wherein said thumb index provides a gripping surface for gripping of said coefficient bar ergonomic bicycle handlebar.

17. The coefficient ergonomic bicycle handlebar system of claim 16 further comprising a kit including: said coefficient bar ergonomic bicycle handlebar and a set of installation instructions.

18. A method of using the coefficient ergonomic bicycle handlebar system of claim 16 comprising the steps of:

a) obtaining a coefficient ergonomic bicycle handlebar;

b) mounting said coefficient ergonomic bicycle handlebar; and

c) gripping said coefficient ergonomic bicycle handlebar.
