The rule
Kansas has no statewide bicycle-helmet law that applies to adult riders. Kansas has no statewide bicycle-helmet law. No Kansas municipality currently mandates helmets for adult cyclists; helmet use is encouraged through public-safety campaigns but not legally required.
What this means in practice
Because there's no statewide age mandate, adult riders in Kansas aren't legally required to wear a helmet — but cycling-injury research still strongly recommends one. Local cities, school districts, and bike-share programs can impose stricter rules, so check the municipal code wherever you ride.
