In order to boot the Green Economy, China encourages its cities to build public bicycle-sharing system which is supposed to reduce the use of private car, and eventually ease the pollution. Hangzhou Public Bicycle, the world’s largest bike sharing facility, has bike stations in such abundance that one can travel the entire city on a bike for free, as the first hour of bike rental is free. Subsequent hours of  riding the same bike can be availed at a very minimal cost.

Tongzhou Public Bicycle is a bicycle sharing system serving the sub-center of Beijing.

Beijing run its public-bicycle system with 50000 bikes from Aug 2007. The system was shortly closed after Olympic Games 2008.

Hangzhou run its public-bicycle system from Mar 2008.

Wuhan run its public-bicycle system in 2009.

But the government run public-bicycle system faces financial criticism, the critics pointed out the unit-price of public bicycle is too high to keep the system running. For example, Hangzhou city spent 450 million RMB for 50000 public bicycles, that's about 9000RMB per bicycle. 20 times higher than common bicycles in the market. Take the dock, computer system, maintenance and relevant facilities into consideration, the cost is extremely huge. There is a smell of corruption.

Every public bicycle-sharing system has docks to park shared bicycles. but dock-less bicycle-sharing is much more popular in China's metropolises.
