This study selected bicycle recreationists as the subjects to investigate the relationship among leisure involvement, leisure-family conflict, and happiness, and intends to closely combine leisure involvement with leisure-family conflict and happiness. The research hypotheses were proposed based on literature review, and a questionnaire survey was conducted on 335 bicycle recreationists. Structure Equation Model was used to verify the cause-and-effect relationship. The research results found that, the recreationists whose level of leisure involvement is higher, the happiness they perceive will be higher. The recreationists whose level of leisure involvement is higher, their leisure-family conflict will be more intense. The recreationists whose leisure-family is more intense, the happiness they perceive will be lower. According to the results, it is advised that, during the continuous participation in leisure activities, bicycle activity participants should maintain the good interaction with their family, which will have a positive influence on the happiness they perceive.
