Hawaii
Last updated
Hawaii is the one state where every e-bike must be registered: a one-time $30 fee paid to the county director of finance (HRS 249-14), with no license and no insurance required for any rider. The state ran on the federal low-speed definition from Hawaii Act 208 (effective July 1, 2019) until Hawaii HB2021, passed April 30, 2026 and law no later than July 15, 2026, adopted the full three-class framework statewide. Class 1 assists only while pedaling up to 20 mph with no minimum age; Class 2 runs on throttle or pedal assist up to 20 mph; Class 3 assists while pedaling up to 28 mph with a required speedometer; and riders under 16 on Class 2 or Class 3 need a supervising parent or guardian.
Hawaii HB2021 also raises the helmet rule to under 18, adds citation or impoundment for riding unregistered, writes the insurance exemption directly into statute, and orders permanent class labels on new e-bikes within 120 days. E-bikes ride wherever bicycles ride, and bike lanes are open to them (HRS 291C-123), with mopeds and electric motorcycles expelled from bike lanes and paths; sidewalk riding is legal at 10 mph outside business districts, matching Honolulu's 2025 ordinance. Land managers decide natural-surface trails trail by trail, and Na Ala Hele trails commonly exclude e-bikes. Over 750 watts and capable of more than 28 mph is a high-speed electric device, banned from every public roadway, path, and sidewalk; Honolulu banned them in February 2025. Our Hawaii bicycle and e-bike insurance page pairs these rules with the state's best rides, riding season, and events. The full breakdown is below.
Hawaii E-bike Laws
The one state where every e-bike gets registered, and the newest to adopt the three-class framework. Here is where Hawaii stands on e-bikes.
Hawaii is the one state where every e-bike must be registered: a one-time $30 fee paid to the county director of finance, and that is nearly the whole rulebook today. No license, no insurance, no classes. The class era arrives this month: Hawaii HB2021, passed April 30, 2026, adopts the full three-class framework statewide no later than July 15, 2026.
The motor assists only while pedaling and cuts off at 20 mph; Hawaii HB2021 sets no minimum age for Class 1.
Throttle or pedal assist up to 20 mph; under Hawaii HB2021 riders under 16 need a supervising parent or guardian.
Assist while pedaling up to 28 mph with a required speedometer; under Hawaii HB2021 riders under 16 need supervision.
No driver license, permit, or ID is required to ride an e-bike anywhere in Hawaii, and Hawaii HB2021 keeps it that way.
Every e-bike carries a permanent $30 registration paid to the county director of finance (HRS 249-14); Hawaii HB2021 adds citation or impoundment for riding unregistered.
Hawaii mandates no coverage for any e-bike, and Hawaii HB2021 writes the exemption directly into statute.
No one under 15 may operate an e-bike (HRS 291C-143.5); Hawaii HB2021 resets the line at 16 for Class 2 and Class 3 unless a parent or guardian supervises, with no floor for Class 1.
Riders under 16 must wear one on any bicycle, e-bike included (HRS 291C-150); Hawaii HB2021 raises the rule to under 18.
Where You Can Ride
