E-Bike Laws
In 2026, Utah passed HB 381 to clarify e-bike laws. The update keeps standard e-bikes the same, adds clearer rules for higher-powered devices, and introduces new safety requirements for youth riders and helmets.
-
Utah uses a three-class system to define e-bikes based on how the motor works and top speed.
Class 1: Pedal assist only, up to 20 mph
Class 2: Throttle assisted, up to 20 mph
Class 3: Pedal assist only, up to 28 mph -
Under 8: Cannot operate an e-bike
Ages 8–15: Must have adult supervision OR a safety certificate to ride independently
Ages 16+: Can ride independently
-
E-bike riders under 21 must wear a helmet when riding on public roads.
This requirement was added under HB 381.
-
To be considered an e-bike in Utah, a device must:
Have operable pedals
Be 750 watts or less
Follow Class 1, 2, or 3 definitions
Devices that:
Exceed 750 watts, or
Can go over 20 mph using throttle alone
Are not considered e-bikes and may be regulated as motor vehicles.
-
E-bikes are allowed on non-motorized state and local trails unless restricted by the city.
Always check local regulations.
-
E-bikes are not allowed on non-motorized federal trails (U.S. Forest Service).
-
You may not operate an e-bike while consuming alcohol or with an open container.

Higher-powered electric devices that do not meet e-bike definitions are treated differently under Utah law.

A driver license
A motorcycle endorsement (for e-motorcycles)
They are not regulated as bicycles.
