I'm not surprised, but I'm also not surprised that people started these schemes in the first place.
My knowledge of China is limited to large cities, where old, rusty bikes are the standard form of transport for most working people. Bikes are everywhere, and frequently carry the whole family, plus the family dog and the family shopping - hundreds of them going along every road, and totally ignoring road signs, one way streets and everything else.
Violent crime is virtually zero in China, with a massive police presence and tough courts, but theft of things like bikes is endemic, which means that everything that can be moved is always locked up. Therefore, there will have been huge interest in bike sharing schemes.
