Bike helmets have proven to be the single most effective safety device in reducing head injury and death in bicycling crashes. Helmets reduce the risk of head injury by as much as 85 percent.
Head injuries incurred while riding a bike result in two-thirds of hospital admissions and more than 60 percent of the bicycling deaths.
Injury is the leading cause of morbidity and mortality for children and young adults living in the United States.
