What the statute actually says

WRONG for a 3-class draft: Hawaii uses the single federal 'low-speed electric bicycle' definition (<750W, motor-only max under 20 mph), no Class 3/28 mph. HRS 291C-143.5 bars under-15 from operating; e-bikes need one-time $30 registration. [Source: HRS 291C-143.5; low-speed e-bike def HRS 291C-1]. Draft — verify against the current statute before relying on it.
