The invention relates to the public transport field and discloses a method for deploying a bicycle between public bicycle stations. The method comprises: constructing a mobile mode topological graph according to historical rent records and distribution of public bicycle stations; dividing the mobile mode topological graph to determine a bicycle deploying region; and according to the user demand, deploying bicycle distribution of the bicycle deploying region. According to the method provided by the embodiment of the invention, bicycles of all stations can be deployed according to the user demand, so that the bicycle distribution can meet the user requirement.
