In honor of National Bike Month and Bike to Work Week, TIME rounded up the best U.S. cities for people who want to commute by bicycle. Many of these cycling-friendly cities have special bike lanes that are protected from traffic, and they also boast bike-sharing systems, plenty of parking spots for bikes, active bike lobbies and mayors committed to enacting policies that make bicycling safer and easier.

To find out which cities to include, TIME asked three veteran bicycle policy advocates: Andy Clarke, president of the League of American Bicyclists—believed to be the nation’s oldest bicycle advocacy organization—Jim Sayer, executive director of the Adventure Cycling Association, and Tim Blumenthal, president of PeopleForBikes.
