Lawmakers in Utah are currently reviewing new legislation designed to update the state’s regulations regarding electric bicycles and other electric mobility devices.
House Bill 381 (HB 381) introduces several modifications aimed at enhancing rider safety, clarifying legal definitions, and resolving the growing confusion surrounding high-powered electric devices that are frequently, and incorrectly, marketed as e-bikes.
Crucially for the cycling community, this proposed bill does not dismantle Utah’s existing e-bike framework. The widely accepted three-class e-bike system will remain intact, meaning that compliant electric bicycles will continue to be treated much like traditional bicycles under Utah traffic laws. Instead, HB 381 focuses on refining definitions, providing law enforcement with better tools, and implementing new safety protocols for specific groups of riders.
As of March 2026, HB 381 remains proposed legislation and has not yet been signed into law.
Understanding Current Utah E-Bike Laws
Under the current Utah Motor Vehicle Code, an electric-assisted bicycle (e-bike) is defined as a bicycle equipped with an electric motor that still operates fundamentally like a traditional bicycle.
To legally qualify as an electric-assisted bicycle in Utah, a device must meet three criteria:
1.It must have fully operable pedals.
2.It must be equipped with a motor of 750 watts or less.
3.It must be capable of being operated without the motor engaged.
The Three-Class System
Utah adheres to the standard three-class system for e-bikes:
- Class 1: Pedal-assist only, where motor assistance ceases at 20 mph.
- Class 2: Throttle-assisted, where motor assistance ceases at 20 mph.
- Class 3: Pedal-assist only, where motor assistance ceases at 28 mph (these models must also be equipped with a speedometer).
E-bikes that fit within these parameters are generally treated the same as standard bicycles. Riders are not required to hold a driver’s license, register the vehicle, or carry insurance.
Age Restrictions and Local Rules
Current Utah law also outlines specific restrictions for younger riders. Individuals under 16 are prohibited from operating a Class 3 e-bike. Riders under 14 must be supervised by a parent or guardian when utilizing the motor, and children under 8 are not permitted to operate any e-bike.
Additionally, local municipalities retain the authority to regulate where e-bikes can be ridden on sidewalks, shared-use paths, and local trail networks.
Proposed Changes Under HB 381
While HB 381 preserves the existing classification system, it introduces several key updates to clarify the regulation of electric mobility devices. This legislation has garnered support from various safety and bicycle advocacy groups, including Bike Utah.
New Definitions for Electric Mobility Devices
One of the most impactful aspects of the bill is the creation of new terminology for electric mobility devices that fall outside the standard e-bike definition.
Electric Motorcycles
HB 381 explicitly states that a motorcycle can be powered by either a traditional combustion engine or an electric motor. Electric motorcycles that exceed the legal limits established for e-bikes will be treated identically to traditional motorcycles under Utah motor vehicle law, meaning they will require proper licensing and registration.
High-Power Electric Devices
The legislation also introduces a new classification: the “high-power electric device.” This category is designed to encompass electric vehicles that surpass the legal limits of an electric-assisted bicycle but are often deceptively marketed as e-bikes. This includes many high-speed electric dirt bikes and throttle-powered devices. Any device capable of exceeding 20 mph using motor power alone falls outside the legal definition of an electric-assisted bicycle.
The necessity of these distinctions was recently highlighted by a tragic case in California, where a father faced felony child endangerment charges after his 12-year-old son was critically injured riding a modified electric motorcycle on a public street. Investigators concluded the vehicle was not a legal e-bike, but rather an e-moto masquerading as one.
Clarifying E-Bike Qualifications
HB 381 reinforces the existing standards for electric-assisted bicycles, specifically the 750-watt motor limit and the requirement for operable pedals. A critical clarification in the bill is that motor power alone cannot propel the device beyond 20 mph. An e-bike is only permitted to exceed 20 mph when the rider is actively pedaling, as is the case with Class 3 pedal-assist models that can reach 28 mph.
Programmable E-Bikes
Addressing modern e-bikes that allow riders to toggle between different operating modes, HB 381 stipulates that programmable e-bikes must fully comply with the rules of the specific class in which they are operating at any given moment. This provision targets devices designed to temporarily bypass legal speed limits via software adjustments.
New Safety and Enforcement Measures
Helmet Requirements for Riders Under 21
Under the proposed law, riders under the age of 21 would be required to wear a helmet when operating certain electric mobility devices on public roadways. Notably, this requirement would not extend to shared paths, trails, or bike-share programs. The bill also includes a provision ensuring that the failure to wear a helmet cannot be used to reduce compensation in a civil injury claim.
Electric Mobility Safety Certificate
HB 381 proposes the creation of a new electric mobility safety certificate program. Under this initiative, riders under 18 would be required to complete a safety course before riding on public roads. Adults who do not possess a valid driver’s license would also be required to complete the course. Expected to be an online program similar to hunter or boating safety courses, it aims to educate riders on basic traffic laws and safe riding practices.
Restrictions on Modifications
To combat the trend of riders altering their e-bikes to boost speed or power, HB 381 makes it illegal to tamper with or modify an e-bike beyond its original manufacturer settings. Violations would carry fines of $100 for a first offense and $250 for subsequent offenses.
Alcohol and Open Container Rules
The bill expands current alcohol restrictions, making it unlawful to consume alcohol or possess an open container while operating any electric-assisted bicycle on a public road. Previously, this rule only applied to specific classes of electric devices.
Enforcement Authority Regarding Minors
HB 381 grants law enforcement officers new authority when dealing with underage riders. If a rider under 18 commits a violation, an officer may temporarily impound the electric mobility device, releasing it only to a parent or guardian. This measure is intended to deter unsafe riding and ensure parental involvement when infractions occur.
Seller Disclosure Requirements
To combat marketplace confusion, the bill requires sellers of high-powered electric devices that do not qualify as legal e-bikes to provide clear disclosures. Sellers must explicitly state that the vehicle is not an electric-assisted bicycle and that it may be subject to motor vehicle laws, including registration and insurance mandates.
What Remains Unchanged
Despite these comprehensive updates, HB 381 leaves several foundational elements of Utah’s e-bike laws untouched. The bill does not require insurance, vehicle registration, or a driver’s license for legal e-bikes. It does not eliminate the three-class system, nor does it re-classify legal e-bikes as motor vehicles.
Electric-assisted bicycles that meet Utah’s established definitions will continue to enjoy the same legal standing as traditional bicycles. This measured approach stands in stark contrast to recent developments in states like New Jersey, which recently enacted a controversial law dismantling the three-class system in favor of a restrictive, motor-vehicle-style regulatory framework that treats many e-bikes like mopeds.
The Road Ahead
HB 381 represents a thoughtful legislative effort to clarify the rules of the road for electric mobility devices. By clearly distinguishing between electric-assisted bicycles, high-power electric devices, and electric motorcycles, Utah lawmakers are working to close regulatory loopholes that have caused widespread confusion.
As the legal landscape surrounding e-bikes continues to evolve, it is crucial for riders to stay informed about how their devices are classified and regulated. We will continue to monitor the progress of HB 381 and any future legislation that impacts cyclists across Utah.
