Bicycling is a sport that places participants at risk of concussions and head injuries. Each year in the US there are approximately 80,000 bicycling related head injuries that require treatment in an emergency room.[1] Roughly 33% of non-fatal bicyclist injuries are to the head. Many casual and even professional bicyclists don't take safety precautions seriously, and in 2016 more than half of bicyclists involved in fatal crashes were reported not wearing a helmet.[citation needed]
