While bicycles are not a recent technological innovation, sometimes the greenest solutions are the simplest. In recent years, cities across North America have increasingly made it easier for residents and visitors to navigate on bicycles. According to the North American Bikeshare Association, in 2016, there were 50,000 bikeshare bikes in rotation, and as of 2017, 130 North American cities had implemented a bikeshare program. In Texas, the Fort Worth B Cycle
bikeshare program offers a service designed for private groups: For an added fee, the company will deliver and pick up the bikes from your specified location, making it easy for guests to transport themselves from one location to another. In Philadelphia, Indego
offers on-demand bikes that riders can pick up at stations around the city, and the company recently introduced a pilot program for electric bikes as well.
