Hi, Now I stay in Beijing. I want rent Bike for 3 weeks. and where I can rent Bike. and how much ?

Hi, there are public bicycles for rental in the city and they are available at many sites. Let me know your location and I can tell you a relatively nearer one. And it costs CNY10 per day (24 hours). I also heard you have to have a Transportation Smart Card for convenience of bike rental.
