Abstract:
A bicycle suspension system comprising:a control unit; a suspension configured to be coupled between first and second parts of a bicycle that are movable relative to each other in response to a shock applied to the bicycle, said suspension being selectively adjustable by said control unit to change stiffness of said suspension; a bicycle driving sensor operatively coupled to said control unit to input a first signal that is indicative of bicycle driving force; a velocity sensor operatively coupled to said control unit to input a second signal that is indicative of forward velocity; a wheel terrain sensor operatively coupled to said control unit to input a terrain signal that is indicative of an amount of compression or expansion of said suspension based on at least one of a plurality of conditions including forward velocity, tilt, horizontal acceleration and vertical acceleration of the bicycle; and a controller operatively connected to said suspension and said control unit so that said control unit selectively adjusts stiffness of said suspension in response to at least said bicycle driving force.
