Minnesota police are warning riders about new rules for powerful electric bikes.

Police across Minnesota are seeing more complaints about high-powered electric bikes being used in places meant for regular bikes and standard e-bikes.

Under a new state law, e-bikes with less than 1500 watts of power are still treated like bicycles. These can be ridden on most sidewalks and bike trails, and riders do not need a license or insurance.

When an electric bike has more power — like the 8,000-watt model it is considered an e-moto.

They're classified 100% as a motorcycle. So when riding this, you need to be at least 16 years old with your motorcycle license. You're going to have to have insurance. You're going to have to have a license plate and registration.

Police are also noticing more kids under 15 riding power-assisted bikes, which is only allowed on private property.

Blaine police are starting the season by sharing information, but will soon begin confiscating illegal e-motos and issuing tickets. Driving without a license is a misdemeanor.

Blaine police say sidewalk riding is a major concern, especially with faster e-motos.
