May is National Bike Month, and more universities continue to commit to bicycling as a sustainable, healthy and environmentally conscious transportation choice. Recently, Harvard University joined Princeton and Yale as an official Bicycle-Friendly University (BFU), and the League of American Bicyclists designated 14 new BFU members, expanding the program to 58 colleges in 30 states across the U.S. with more to come.

When New York City opened registration for a public bike-sharing program, Citi Bike, more than 5,000 people signed up within 30 hours. Similar demand for more cycling options is happening across the nation where shared bicycle programs are taking root (see Tinyurl.com/Top50BikeFriendliestCities).

The popular Washington, D.C., Capital Bikeshare program began operating in September 2010, and is now the nation’s largest, with 200 locking docks able to accommodate more than 1,800 bright-red bicycles. As in many programs, people can sign up for a short-term stint or an annual membership using either a credit card online or at a station kiosk. Then they can unlock a bicycle and return it to any station within the system. All rides under 30 minutes are free, after which escalating fees kick in, encouraging people to make short trips and to keep more bikes available for other riders.
