Yes. Each year, bicycle-related deaths number about 900, and United States hospital emergency rooms treat more than 500,000 people for bicycle-related injuries. More children, ages 5 to 14, go to U.S. hospital emergency rooms for injuries associated with bicycles than with any other sport. Many of these injuries involve the head. If you do not wear a bicycle helmet, you are risking your life.
All young children should wear a bicycle helmet, whether they are riding bicycles, tricycles, or are passengers on a parent's bicycle. Never carry a child under age 1 on your bicycle.
