An exercise bicycle includes a flywheel, a drive train coupled to the flywheel, and pedals coupled to the drive train. A user of the exercise bicycle expends power by exerting force on the pedals to spin the flywheel. The exercise bicycle further includes a power meter. The power meter includes a friction pad comprising a flywheel contact surface in contact with the flywheel and a temperature sensor located within the friction pad. The temperature sensor measures the temperature of the flywheel contact surface. The power meter further includes an output meter coupled to the temperature sensor, the output meter converting a temperature change of the flywheel contact surface as measured by the temperature sensor into a calculated power expended by the user.
