One of many bikeshare clusters on the sidewalk boulevards in Shanghai. Mobike orange, Ofo yellow and Xiaoming blue services don't have dockng stations, it's easy for a subscriber to scan a barcode with a mobile phone to unlock the clamp, ride away, and drop off near destination. High volume cheap bikes everywhere are a sharp contrast to the North American style of higher quality infrastructure spread further apart. (Tongji University, Shanghai, P R China) 20170406
