According to a recent Guardian article - 'China backs bikes to kick car habit' - that bikes are back in fashion and to be, once again, encouraged... no doubt because of the rising environmental concerns:
"The construction ministry announced on Thursday that any bike lanes that have been narrowed or destroyed to make way for cars in recent years must be returned to their original glory. This followed orders on Tuesday that all civil servants should cycle to work or take public transport to reduce the smog that chokes most city streets and urban lungs.
The apparent shift of focus comes at the start of a new five-year economic plan in which the government says its priority is to improve the environment and conserve energy. Earlier this month, the World Bank issued a new report calling on China to invest more in public transport rather than focusing on the construction of new highways for cars."
