The purpose of this study was to investigate the relationship between the degree of participation in leisure activity, organizational identification and organizational commitment with the emphasis on bicycle riding club members. A total of 265 respondents were selected using the purposive sampling method. From the statistical analyses, three meaningful results were extracted. First, there were differences in the degree of bicycle riding participation, organizational identification and organizational commitment on the basis of individual background characteristics. Second, the age and the monthly income of riding club participants partly influenced the degree of bicycle riding participation, organizational identification and organizational commitment. Third, the degree of bicycle riding participation directly or indirectly had influences on organizational commitment mediated by organizational identification. As a result, we found the fact that beside the degree of bicycle riding participation, the age and the monthly income of riding club participants also have influences on organizational identification and organizational commitment.
