Both　of　the　transportation　and　the　public　hospital　outpatient　services　are　the　key　public　services　provided　by　the　government,　which　guarantee　the　safe,　healthy　and　worthwhile　life　for　daily　living　in　metropolitan　cities　such　as　Beijing　and　Hong　Kong.　Since　the　citizens　usually　have　to　see　their　medical　doctors　at　the　appointed　time,　they　should　arrive　punctually　as　scheduled　for　their　outpatient　services　in　public　hospitals.　In　order　to　find　out　how　people　travel　to　the　public　hospitals　for　their　scheduled　outpatient　appointments　particularly　before　and　after　the　bike-sharing　system　in　Beijing,　two　interview　surveys　with　a　total　of　1,047　valid　samples　were　conducted　at　the　Beijing　Friendship　Hospital　in　October　2016　and　2017.　One　was　before　the　launch　of　the　floating　bike-sharing　system　in　November　2016　while　the　other　one　was　conducted　in　October　2017　after　this　new　system　has　been　implemented　in　Beijing　for　about　one　year.　Compared　to　the　other　non-motorized　travel　modes,　the　bike-sharing　mode　could　provide　the　best　trip　experience　with　the　highest　evaluation　scores　on　the　satisfaction,　the　comfort,　the　convenience　and　the　punctuality　of　the　outpatient　trips.　Multinomial　Logit　(MNL)　model　is　calibrated　to　investigate　the　factors　to　influence　the　travel　mode　choice　for　outpatient　trips.　The　results　show　that　the　outpatient　travelers　are　likely　to　choose　the　bike-sharing　mode　for　their　return　outpatient　visits　at　public　hospitals　in　Beijing.　Other　factors　like　online　map-usage,　the　acceptable　maximum　walking　time　and　cycling　time,　the　weekend　appointment　for　outpatient　services　and　the　household　income　have　positive　impacts　on　the　choice　of　the　bike-sharing　mode.
