Honolulu police say a mix of new enforcement and a fresh state law has cut down on illegal e-bike and electric dirt bike trouble on Oahu — good news for residents after a year of crashes and deaths.

• Illegal electric dirt bikes and e-bikes are showing up less on Oahu roads, especially in the Eva Beach and leeward coast area.
• Residents are filing fewer complaints, and police have handed out more citations, arrests, and seizures than last year — 49 citations so far this year.
• Riding an illegal electric dirt bike is treated like driving without a license, which can get a rider arrested.
• A new state law, Act 259, lets police seize and auction off illegal devices and sets safety standards.
• A school campus ban on e-bikes may be discouraging teens from riding them.

Outlook: Police plan to keep up enforcement, so the drop in illegal e-bike use on Oahu is likely to hold.
