Wheels! The Kids' Bike Book — Megan Stine Published by Little, Brown and Co./AOL Time Warner, 1990. Mountain bikes, BMX bikes, racing bikes, touring bikes—how do you decide which is the best bike for you? This book will help you. First, look at the different types of bicycles. What are the different parts of each bike for? Next, consider how to keep your bike in top riding condition. Also, what do you need to stay safe and look good? There is even a section on some unusual bikes, such as one built for 10 people! Trivia quizzes, puzzles, bike slang, and tips on touring and racing are featured. Bright color photos and diagrams capture all the two-wheeled action. A glossary, lists of biking organizations and books on biking, and information about accessing biking information through your computer are all included.
