A picture book about vehicles and things that go-in this case, bicycles and unicycles-by Byron Barton, the acclaimed creator of My Car, My Bus, and numerous other classic titles! Tom, the narrator of this cheerful picture book for preschoolers, is the proud owner of a bright green bicycle. After Tom describes all the parts of his bike, he rides the bike to work. He rides along busy roads and bustling streets, past cars and buses and animals and people, until he arrives at the circus, changes into his work clothes, and goes to work. It turns out that Tom is a clown, and his job is to ride a unicycle on a high wire under the big top! A fresh and fun look at riding (on two wheels and one), community, transportation, and professions, with a surprise ending!
