Non-motorized transport modes are often considered an essential element of a sustainable transport system. The bicycle is one element of Non-motorized transport modes that are widely recognized as an environmentally friendly and healthy mode of transportation. In Thailand, a Bike-Sharing Program (BSP) was initiated by Bangkok Metropolitan Administration (BMA) under the name of PUNPUN which to encourage the bicycle usage for short-distance trips in the central business district. On the other hand, PUNPUN is not as popular. This paper aims to provide an overview of the current of BSP in Bangkok and to analyze the factor affecting of the PUNPUN users in each station. The results show that the ridership of PUNPUN tends to increase with attractive points such as shopping center, recreational areas, etc., and the system characteristics; the number of public bikes and docking stations including operation policy. It also is useful in determining for the government policy to encourage bicycle use and to select the location of the rental station.
