According to historian Amir Moghaddass Esfehani, who wrote “The Bicycle and the Chinese People”, the Chinese first learned of bicycles from a customs official who visited Paris in 1866. He wrote of Parisians riding vehicles made of “two wheels with a pipe in the middle.” Now of the 130 million odd bikes manufactured ever year, China makes about 70%. And despite China’s recent rapid modernization, they’re still growing in popularity. In celebration of this enduring love affair, Chinese photographer Zhao Huasen has put together a series of cool pics of people in riding around on invisible bicycles.
