Keep yourself safe while biking! Wear a helmet and make sure it fits correctly. Here is some great information from the Minnesota Bicycling Handbook created by the Bicycle Alliance of Minnesota.
Your helmet should sit level on your head and low on your forehead – one or two finger widths above your eyebrows.
Adjust the slider on both side straps to form a V-shape under and slightly in front of each ear.
Does your helmet fit right? Open your mouth wide…big yawn! The helmet should pull down on the head.
