China sets the pace on bike sharing
In seven years the mainland has gone from no public bicycles to 650,000 as it tackles pollution

Back in the summer of 1965, a group of self-styled anarchists whitewashed 50 bicycles and stationed them in the centre of Amsterdam.

The plan backfired - the bikes were confiscated by the police - but it offered a glimpse of the future. Now that playful act of defiance has gone mainstream.
With the bike-sharing boom still in its first decade, Asia is already outpacing European towns that started the phenomenon.
The Chinese cities of Hangzhou and Wuhan are the global leaders; India's megacities are struggling to take off; the United States is playing catch-up; Africa hasn't started.
From flat Astana, Kazakhstan, to Quito, Ecuador - with an altitude of 2,800 metres above sea level - bike-sharing programmes exist in more than 600 cities in 52 countries, says Russell Meddin, who maintains and updates The Bike-Sharing World Map, a website that surveys cycle plans around the globe.
