A universal mount bicycle power meter module has a base member with first and second ends and a narrow central portion which is relatively compressible in response to applied forces. Firmly secured to the first end is an internally threaded mounting nut in registration with an aperture in the first end. The nut secures the first end of the base member to an externally threaded end portion of a bicycle axle. The second end of the base member is configured to be firmly secured to a rear frame portion of a bicycle using a mounting clamp. A strain gauge sensor assembly is mounted on the central portion of the base member to generate resistance values representative of the amount of compression in the central portion. The sensor assembly is coupled to a signal processing unit having circuitry for converting the resistance values and bicycle velocity signals from an associated bicycle speedometer to cyclist power signals.
