Aerodynamics

Comparison : Theses comparative measurements were made : - without pedalling   - going downhill - without wind H-Zontal enable to aquire 20 % more speed than a traditionnal bike ! ...or 20 % less effort !

Explications :

On a classical bike, the body axis is perpendicular to the moving direction and the aerodynamic turbulences increases exponentially with increasing speed and therefore you are slowed down considerably. On a recumbent bicycle, (prone or supine), the body axis is parallel to the moving direction. So the performances are superior (speed record are : 130km/h for 200 m flying start speed trial, and 86 km for 1 hour) On the H-Zontal bike, the back is completely straight and is parallel to the moving direction. The head and the legs are also in the continuation of the body and therefore the turbulences are minimised.
