ABSTRACT:
A circuit for producing a display indicative of a bicycle rider's pedaling technique. The circuit measures the time required for the pedals to move through a given angle of rotation. The circuit then calculates the relative pedal velocity over the angle of rotation. This process is repeated over an entire circle of rotation to determine the variations in pedal velocity as the pedal moves through a full circle. Since the pedal velocity is related to the pedaling force applied by the rider, the variations in pedaling force can be determined. Further, the circuit has a display unit which shows a rotating line of varying length to indicate the pedaling force applied as the pedals move respectively through a full circle.
