This book examines the surging national interest in bike-friendly public policies and argues that this growth is likely to escalate. Currents in U.S. culture that have supported the dominance of the car are edging toward exhaustion. At the same time, other factors including congestion, contentious and unreliable energy resources, rising pollution, and global warming support the expansion of the bike's use. A surprising array of political organizations, visionary politicians, and colorful individuals powers this movement.
