Peppas introduces some surprising facts about the world of motorcycles in another of the “Vehicles that Move” series. More than 6 million people in the U.S. ride motorcycles, some of which can travel more than 200 miles (322 km) per hour. The many uses of these vehicles include military and police department work, not only in the U.S. but also in forty-five other countries. From cowboy work of rounding up cattle to purely recreational activity, the motorcycle is here to stay. Color photographs on each page add interest to the already fascinating text.
