Welcome! We are a helmet advocacy program founded in 1989. We are a small, active, non-profit consumer-funded program providing bicycle helmet information. We are a 501(c)3 non-profit, so your contributions to us are tax-deductible. We try to explain the technology of helmets to consumers, and promote better helmets by working on improved standards. In a typical year our secure server serves 2 million pages to more than 700,000 distinct users. Our volunteers serve on the ASTM helmet standards committee and are active in commenting on actions of the Consumer Product Safety Commission. We are members of the National Bicycle Safety Network. We provide a Toolkit of materials for helmet programs and a periodic email helmet newsletter, both free. We are all volunteers, funded entirely by consumer donations. We maintain our independence by never accepting funds from the industry. As much as we believe in helmets we still consider them a secondary safety measure and urge that primary measures such as safer roads and education programs for riders and drivers not be neglected.
