Two percent of motor vehicle-related deaths are cyclists although bicycle trips account for less than one percent of all trips in the U.S. In 2006, more than 44,000 bicyclists in the U.S. were injured in traffic crashes and 773 bicyclists died as a result of bicycle-related injuries. Eight-five percent of bicycle deaths are persons 16 and older. The most serious injuries among a majority of those killed are to the head, highlighting the importance of wearing a bicycle helmet. Ninety-five percent of the bicyclists killed in 2006 reportedly weren't wearing helmets.
Although it is estimated that less than 1 percent of adult Americans commute to work by bicycle, roughly 41 percent of work commutes are shorter than 5 miles. For many people this is an easy distance to bike. At about 10 miles per hour, this would be a 30 minute bicycle ride and would allow employees to get CDC’s recommended level of physical activity.
