People Powered Movement is a biking and walking resource. Our goal is to help increase bicycle usage and pedestrian access throughout U.S. cities. Our mission: Creating, strengthening and uniting state and local bicycle and pedestrian advocacy organizations. The Alliance for Biking & Walking, formerly known as Thunderhead Alliance, is the North American coalition of grassroots bicycle and pedestrian advocacy organizations. We unite advocacy leaders to help them become more effective by sharing best practices and innovations. We strengthen organizations through resource sharing and training opportunities. We help advocates create organizations in underserved communities. Alliance organizations are working together to transform communities into great places to bike and walk.
