Bicycle is a popular vehicle by the low price and the easy maintenance in comparison with car and motorcycle. In order to expand the popularity of the bicycle, improvement of the ride comfort is essential. Specifying which part and frequency band affects the ride comfort and reduction of the vibration of the part are important to improve it. In this study, we investigated them through subjective evaluation test and vibration analysis, and we tried to reduce the vibration. Through the subjective evaluation test, the seat vibration less than 40 Hz was found to have large influence on the ride comfort. Subsequently, we considered applying a dynamic vibration absorber to reduce the low frequency vibration using existing parts not to increase total weight and cost. Then, we chose rear carrier and used it as dynamic vibration absorber, and modified the structure to meet the resonance frequency with a frequency where the seat vibration was large at running condition. As a result, the seat vibration was reduced, and the ride comfort was improved.
