Electric bicycle classes, age, helmets, and path access

California defines three e-bike classes up to 750 watts. Class 3 operators must be at least 16 and operators and passengers must wear helmets; bicycle riders under 18 also have a helmet requirement. Class 3 path access is generally limited to paths adjacent to a roadway or locally permitted paths, and local authorities may restrict e-bike operation on paths. 2026 amendments also address Class 3 sales to minors and rear lighting/reflectors.
