This is a vintage treatise on the use of a bicycle ergometer in the measurement and the computation of the amount of energy used by the human body. At its core, it is an exploration of the mechanical efficiency of the human body as a machine, as well as a technical manual for the calibration and use of a bicycle ergometer. "A Bicycle Ergometer with an Electric Brake" is recommended for modern cycling enthusiasts and collectors of vintage literature of this ilk. Contents include: "Detailed Description of the Bicycle Ergometer", "General Considerations regarding Method of Use", "Method of Calibration", "Calibration Tests", "The Technique of a Calibration Experiment", "Earlier Calibration Tests", "Friction tests with Ergometer II", "The Magnetic Reactions Produced by a Copper Disk Rotating Between the Poles of a Magnet", et cetera.
