A bicycle is a popular vehicle for a lot of people by the low price and the easy maintenance in comparison with a car and a motorcycle. In order to expand the popularity of the bicycle, improvement of the ride comfort is necessary. In this study, to improve the ride comfort of a utility bicycle, subjective evaluation tests and acceleration measurements were performed. In the subjective evaluation test, the vibration feeling of the seat and the ride comfort of bicycles were evaluated by using five kinds of bicycle. And the vibration accelerations of the seats were measured and frequency analysis was performed to obtain which frequency band has high contribution to the ride comfort. As a result, low frequency vibration of the seat was clarified to have high contribution to the ride comfort. Next, the seat vibration reduction was tried. For decrease of the seat vibration, the spring rate of the seat was reduced. As results, the acceleration level was decreased in the running test and the ride comfort was improved.
