ABSTRACT:
The bicycle has a frame on which a front wheel and a rear wheel are rotatably mounted. At least one of these two wheels is connected to at least one device using wind-generated Bernouilli force to assist forward motion of the bicycle. Such device has a wind-driven turbine with a plurality of horizontal air foils attached to a shaft rotatably mounted about a horizontal axis. It also has a shield positioned adjacent to part of the turbine to deflect wind and prevent it from impacting the air foils when they rotate forwardly. A clutch is operatively connected to the shaft of the turbine to the wheel for transferring the force generated by the wind within the turbine to this wheel.
