Tom, the narrator of this cheerful preschool picture book, is the proud owner of a bright green bicycle. After Tom tells readers about 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 (sharp-eyed readers will have fun finding the characters and vehicles from My Bus and My Car in the busy artwork), 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!
