Best-known info — always verify before you ride.
E-bike laws change frequently, and rules can differ by city, county, park, trail network, and even ZIP code within a single state. This page reflects the most current statewide framework we can confirm, but it is not legal advice. Always double-check with the Hawaii DOT/DMV, your local municipality, and any park or trail authority before relying on it.

The 3 e-bike classes
Full explainer with pictures
You pedal, motor helps. Stops helping at 20 mph.
Pedal-assist only (no throttle). Motor cuts out at 20 mph. The most permissive class — broadly allowed wherever traditional bicycles are allowed.

Throttle like a scooter. Also stops at 20 mph.
Throttle-assist + pedal-assist. Motor cuts out at 20 mph. Often restricted on natural-surface and singletrack trails.

Pedal-assist only, but faster — up to 28 mph.
Pedal-assist only, with motor cutout at 28 mph (some states 25). Usually carries the most additional restrictions — minimum age, helmet, no multi-use paths.
Learn moreFederally, an e-bike is a bicycle under CPSC 16 CFR Part 1512 if it has fully operable pedals, an electric motor under 750W, and a top motor-assisted speed under 20 mph. Anything outside those bounds may legally be a motor vehicle under federal law, regardless of how a state classifies it. For questions or legal advice, visit EBikeSafety.com.
Local rules can override
What the state framework doesn't tell you.
Within Hawaii, cities, counties, parks, school districts, university campuses, and trail systems frequently impose their own e-bike rules — and those rules win when they're stricter than the state framework. Beach cities, college towns, dense downtowns, and popular trail networks are the most common places to find local additions.
Before you ride somewhere new, check: the city or county code, the park or trail authority's posted signage, and (if it's a State Park, National Park, National Forest, or BLM land) the relevant federal land-management rules.
