Forty years ago, China was a country on pedals. Roughly 60 percent of all trips were made on a bike. But as the economy blossomed, the two-wheelers, once considered status symbols, gave way to cars. In the last three years, however, some 60 companies have sprung up to give the tech-savvy, app-happy generation an easy way to get around: shared, dockless bikes. Fueled by venture capital, the companies dumped more than 20 million cheap, brightly colored bicycles onto Chinese streets. Now there's a bike glut and many sit unused in vacant lots. The pictures below offer a top-down on China's bike-sharing bubble.VCG/VCG via Getty Images TAKING OVER THE FOUR-WHEELS
