A few years ago, Beijing was probably the most bicycle-friendly capital on Earth. A flat, dry city with broad, tree-lined cycle lanes patrolled by protective traffic wardens was perfect for two wheels. The streets teemed with so many bicycles that they became as much a symbol of China as the giant panda.
But now they are under threat as their habitat – the city’s network of bicycle lanes – shrinks, and predators – in the form of cars – increase at the rate of 20,000 a month.
