METHOD AND APPARATUS TO MEASURE MOTION CHARACTERISTICS FOR BICYCLES AND ANY VEHICLES ON WHEELS

Patent Pending A sensor system for use with a host device a vehicle having a frame and at least one wheel. The sensor system has a first sensor associated with the at least one wheel of the vehicle. The first sensor generates wheel data indicative of movement of the wheel. The wheel data may be rotational angle, full revolution count, angle of a revolution, direction of revolution, and angular acceleration with respect to a magnetic pole of the Earth or a magnet attached to a frame. The sensor transmits the wheel data to the host device.
