As people look for more sustainable ways to move about, bike sharing has become a legitimate phenomenon, and like every legitimate phenomenon, it can be quantified with trivia.
Treehugger compiled this bike-sharing fact sheet which should give you some idea of how far bike sharing has come.
As of the beginning of this year, around 600 cities in 52 countries host advanced bike-sharing programs, with a global fleet of more than 570,000 bicycles.
Among those countries, China hosts 82 programs with a combined fleet of 380,000 bicycles. Among those is the world’s largest, which has 90,000 shared bikes on the streets of Wuhan, China’s sixth-largest city.
In comparison, the U.S. hosts around 36 programs, while the number of shared bikes is expected to double to over 37,000 this year.
With annual memberships below $100 in most cities, bike sharing is significantly cheaper than the AAA-estimated $7,800 average cost of car ownership. Of course, it comes with environmental and health benefits, too.
