Systems and methods for testing the accuracy of a bicycle training apparatus that is configured to measure the power output of a cyclist riding on a bicycle. The system includes a base, a main drive shaft secured to the base, a motor secured to the base and configured to rotate the main drive shaft, torque and rotational speed sensors configured to measure the torque and rotational speed of the main drive shaft during rotation thereof. The bicycle training apparatus may be secured relative to the base and functionally coupled to the main drive shaft. The motor may then be operated to apply a power input to the bicycle training apparatus while measuring the torque and rotational speed of the main drive shaft and the power input with the bicycle training apparatus. The resulting measurements may be compared to determine the accuracy of the bicycle training apparatus.
