Abstract: 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.

Abstract: The coefficient cycling aero foil system is designed to reduce drag and turbulence from a tire and spokes used to support a bicycle wheel. The system is integrated into a rim on a bicycle wheel which allows for increased forward momentum by cutting drag and reducing wheel turbulence that occurs during the rotation of a bicycle wheel. The foils may be strategically placed for optimum aerodynamic wind flow and are precisely angled to force wind past the foil creating increased forward momentum.
