Interest in bicycling is growing rapidly, with worldwide industry sales up 10 to 25% per year over the past decade. There are currently 450 million bicycles owned in the US, with over 60 million adult riders. Interest in commuting (gas prices), health and fitness (boomers retiring), and environmental concerns (zero emissions) are converging to make bicycling a subject area of continued high growth. This book is designed as an introduction to bicycling, and features current information along with professional quality step-by-step and identification photos.
