Cycling is on the rise across the United States, and its popularity has grown beyond the usual leaders—Portland, Oregon; Seattle, Washington; Davis, California; Minneapolis, Minnesota; and Boulder, Colorado. Other cities making significant investments in bike infrastructure in recent years include New York City; Chicago, Illinois; and Washington, D.C.—all three have realized substantial growth in the numbers of people taking to the streets on two wheels.
