Wyoming e-bike and e-trike laws

✓ Last verifiedVerified Sep 2026Every rule links to the statute or state agency page
In short

Yes. Wyoming defines an e-bike as 'a bicycle or tricycle' with pedals and a motor under 750 watts, so an e-trike needs no license, registration or insurance and has no state helmet or age rule. Ride it on roads like a bicycle; trails are open unless the town or agency in charge restricts e-bikes. Don't ride under motor power on sidewalks.

Does an e-trike count as an e-bike here? Yes.
License
No driver's license, registration, title or insurance is needed; an e-bike is not a motor vehicle.
Registration
No state registration or title, but cities and towns may require local registration/licensing of bicycles and e-bikes.
Helmet
Wyoming has no statewide helmet law for e-bike riders (none found in Title 31 art. 7).
Minimum age
No state minimum age for any class was found.
Where you can ride
E-bike riders have the same rights and duties as other drivers on the road and ride as far right as practicable.
Sidewalks
Vehicles may not be driven on sidewalks other than by human power, so running the motor on a sidewalk appears prohibited statewide; local rules may add more.
Three wheels

Does an e-trike count as an e-bike?

Mopeds are exempt from registration (31-2-224(a)(viii)) and can be driven with any class of driver's license (31-7-109(f)). Motorcycles require registration/title and a Class M license.

What we couldn't confirm from official sources (4)
  • Wyoming State Parks and Game & Fish rules on e-bikes in state parks/historic sites were not reviewed.
  • Section 31-5-707(e) says the motor must stop when the rider stops pedaling, which on its face conflicts with the Class 2 throttle definition.
  • Whether mopeds need liability insurance in Wyoming was not verified.
  • Federal lands (Yellowstone, Grand Teton, national forests) have their own e-bike rules; not reviewed.

This page explains the law in plain language. It is not legal advice. Cities, counties and park agencies can add their own rules; check posted signs and confirm with your state before you ride.
