ABSTRACT:
A bicycle drive sprocket apparatus which allows for varying torque transmission during its rotation and for varying angular velocity of said sprocket when constant rotational force is applied thereto. The device provides for accelerating and decelerating angular velocity during predetermined sectors of the rotational cycle. Through elliptical and other non-uniform radius gear parts, said apparatus converts varying torque inputs into constant torque output. Used as an improved front sprocket for a bicycle, it provides increased resistance to the operator of said bicycle during the downward stroke of the pedal and relatively less resistance during the horizontal portion of the pedal cycle.
