This paper suggests some lessons and strategies from the comparative analysis of operation results and users' behaviour on bike sharing programs of three main cities; Changwon(NUBIJA), Koyang(FIFTEEN) and Daejeon city(TASHU). We analyzed characteristics of business model, operation results and behaviour of users by data from three operation centers. Also, we used intercepted interview results for complement of the data analysis based on the usage records. The results show that there were several differences among cities including two times of average daily trip numbers per bike among three systems. More service density and coverage ratio contributed to more utility trip and substitution of private car. These are resulted from the level of service density, payment structure, level of public transportation, trip distance by urban structure including general factors such as bicycle infrastructure, attitude on bicycle and etc. Therefore, the strategy of bikesharing program should offer minimal level of service in terms of density and coverage and set up their service target depends on urban condition such as urban size, bicycle familiarity and etc.
