Bike rental is an important traffic mode under the low-carbon mode. Bike rental pricing is the key technology of the bike rental. In the paper, bike rental pricing model is researched. Firstly, the influential factors of the bike rental pricing are analyzed, such as cost, demand, rental location, time, depreciation rates, government policy, competition conditions, income level, psychological pricing, the other public transport pricing situation and so on. Secondly, the average-cost pricing and the Logit model are combined, and the pricing model is established by considering the depreciation rate, the distribution rate, the ratio of the travel time and the rental time. Finally, the model is solved. According to time, rental location and bike models, the price of bike rental and the appropriate deposit of bike can be determined by using this model.
