Hawaii eBike Laws (2026)

Hawaii has unique eBike regulations that differ significantly from most mainland states. eBikes with motors exceeding 1,000W or capable of speeds over 20 mph without pedaling may be classified as mopeds, requiring registration and a driver's license. Class 1 eBikes (pedal-assist, 20 mph max) are generally treated as bicycles. Helmets are required for all riders under 18 and recommended for all riders. Riders should verify county-specific rules as Hawaii counties have significant regulatory authority.
