Patent ID: 6880844

Claim:
In a bicycle comprising a frame on which a front wheel and a rear wheel are rotatably mounted, the improvement wherein at least one of said wheels is connected to at least one device using wind-generated Bernoulli force to assist forward motion of said bicycle, said at least one device comprising: a wind-driven turbine comprising a plurality of horizontal air foils attached to a shaft rotatably mounted about a horizontal axis; a shield positioned adjacent to part of the turbine to deflect wind and prevent said wind from impacting the air foils when they rotate forwardly; and a clutch operatively connecting the shaft of the turbine to said at least one wheel for transferring the force generated by the wind within said turbine to said at least one wheel, wherein the shield is provided with an internal channel extending from a front opening through which wind may enter to a rear outlet through which the wind diverted through the internal channel may be injected rearwardly behind the air foils while said air foils rotate forwardly.
