Abstract: The invention relates to a system for measuring real-time aerodynamic drag of a moving vehicle, for example, a bicycle and rider. The system comprises a processor and a non-transitory computer medium for storing data. Further, it comprises a single, compact, multi-port measurement system (MPMS) comprised of at least two differential pressure sensors electrically connected to the processor and the non-transitory computer-readable medium, wherein the processor is configured to convert a first differential air pressure from a first sensor to a wind speed, and to convert a second differential air pressure from a second sensor to a wind direction. The system further comprises a plurality of sensors for detecting forces, including barometric pressure, air temperature and relative humidity, distance, and speed, surrounding the moving vehicle. The plurality of sensors are electrically connected to the processor and the non-transitory computer-readable medium, and also store data.
