According to NACTO figures, bikeshare rides per day went from a third of a million in 2010 to 28 million for 2016 – a nearly 100x increase. For the last two years, bikeshare has been growing at about 25 percent annually. Sounds like a lot, until you realize that Americans take some 400 *billion* trips a year, the vast majority of that by car. But could the newest generation of bikeshare – systems with no docks – become the most sweeping change to American cities for the next couple of years.
