Ergonomic bicycle handlebar systems
A bicycle handlebar system that ensures comfort, safety, and increased center of gravity control. An ergonomic bicycle handlebar system having a sweep angle in the range of 4 to 45 degrees, a slope angle in the range of 5 to 60 degrees or both accomplishes comfort, safety, and increased center of gravity control. The handlebar may be made of nano tube zlyte resin with graphene-impregnated carbon fibers. The interplay of sweep angle and slope angle is recognized.
1. A bicycle handlebar comprising:

the left inner grip portion extending upwardly relative to the stem clamp axis and to the left of stem clamp area,
the right inner grip portion extending upwardly relative to the stem clamp axis and to the right of the stem clamp area,
the left outer grip portion connecting to the left inner grip portion at the left inner grip portion's most forward and upward point and extending to the left therefrom with a slope angle of between five and sixty degrees and a sweep angle of between four and forty-five degrees,
the right outer grip portion connecting to the right inner grip portion at the right inner grip portion's most forward and upward point, and extending to the right therefrom with a slope angle of between five and sixty degrees and a sweep angle of between five and sixty degrees,
a left drop affixed to the leftmost end of the left outer grip portion, and
a right drop affixed to the rightmost end of the right outer grip portion.

the left inner grip portion extending upwardly relative to the stem clamp axis and to the left of stem clamp area,
the right inner grip portion extending upwardly relative to the stem clamp axis and to the right of the stem clamp area,
the left outer grip portion connecting to the left inner grip portion at the left inner grip portion's most forward and upward point and extending to the left therefrom with a downward slope angle and a backward sweep angle,
the right outer grip portion connecting to the right inner grip portion at the right inner grip portion's most forward and upward point, and extending to the right therefrom with a downward slope angle and a backward sweep angle,
a left drop affixed to the leftmost end of the left outer grip portion, and
a right drop affixed to the rightmost end of the right outer grip portion.
