Understanding factors that influence wheel vibration may have practical applications for cyclists and manufacturers. However, a reliable method to measure these vibrations and tools to interpret the data are needed. PURPOSE: To establish a methodology to measure vibration of the road bicycle wheel and to quantify measured vibrations resulting from changes velocity, tire pressure, and surface roughness. METHODS: A single participant cycled on stationary cycle rollers with different tire pressure, speed, and surface roughness conditions. An accelerometer was mounted to rim of the front wheel. Data were analyzed in the frequency domain following a Fourier Transformation. Data were reduced by calculating the sum power for each trial, Peak to Average Power Ratio (PAPR), and Frequency at a Percent of Sum Power (FPSP). RESULTS: PAPR showed a clear distinction between the smooth and rough rollers. FPSP showed little change with pressure or speed for the smooth roller condition. For the rough roller condition, changes in speed showed an increase in FPSP at different percent of sum power levels around the 80-100Hz range. CONCLUSION: Data reduction and analysis techniques were successful at identifying changes in vibration between conditions.
