The short answer
A qualifying e-bike uses one of three classes below 750 watts. Wyo. Stat. § 31-5-707 exempts its operator from Title 31 provisions on financial responsibility, driver's licenses, registration, and certificates of title, and says the e-bike is not a motor vehicle. Local authorities may regulate and locally register or license e-bikes, while the responsible local authority or state agency may regulate any class on trails.Wyoming Legislature — current Title 31 Spot an error? →
01 / Categories
Pedal assist · 20 mph
It must be a bicycle or tricycle with fully operable pedals, a rider's seat or saddle, an electric motor of less than 750 watts, and the motor behavior and assisted-speed cutoff of Class 1, 2, or 3.Wyoming Legislature — current Title 31 Spot an error? →
The motor assists only while the rider pedals and stops providing assistance when the bicycle reaches 20 mph.Wyoming Legislature — current Title 31 Spot an error? →
Throttle-capable · 20 mph
The motor may propel the bicycle without pedaling and is not capable of providing assistance when the bicycle reaches 20 mph.Wyoming Legislature — current Title 31 Spot an error? →
Pedal assist · 28 mph
The motor assists only while the rider pedals and stops providing assistance when the bicycle reaches 28 mph.Wyoming Legislature — current Title 31 Spot an error? →
02 / Class consequences
| Class | Motor behavior | Assisted cutoff | Core consequence |
|---|---|---|---|
| Class 1 | Pedal assist only | 20 mph | A qualifying Class 1 e-bike receives § 31-5-707's state paperwork exemptions. A manufacturer or distributor must permanently label its class, top assisted speed, and motor wattage, and the responsible local authority or state agency may regulate it on trails.Wyoming Legislature — current Title 31 Spot an error? → |
| Class 2 | May propel without pedaling | 20 mph | A qualifying Class 2 e-bike receives § 31-5-707's state paperwork exemptions. A manufacturer or distributor must permanently label its class, top assisted speed, and motor wattage, and the responsible local authority or state agency may regulate it on trails.Wyoming Legislature — current Title 31 Spot an error? → |
| Class 3 | Pedal assist only | 28 mph | A qualifying Class 3 e-bike receives § 31-5-707's state paperwork exemptions. A manufacturer or distributor must permanently label its class, 28 mph top assisted speed, and motor wattage, and the responsible local authority or state agency may regulate it on trails.Wyoming Legislature — current Title 31 Spot an error? → |
Classification unclear: the device does not fit Wyoming's electric-bicycle definition, but the cited statute does not assign every over-power, over-speed, throttle-over-20, or pedal-less device to one automatic replacement category. Confirm the exact vehicle before using it on public roads or paths.Wyoming Legislature — current Title 31 Spot an error? →
03 / Rider requirements
Whether adults must wear a helmet is unclear. Section 31-5-707 states neither an adult helmet mandate nor an exemption, and the cited sources give no express statewide yes-or-no answer. Check local rules, and wear one anyway.Wyoming Legislature — current Title 31 Spot an error? →
04 / Where you can ride
Wyoming supplies an on-road framework: § 31-5-702 gives every e-bike rider all rights and duties applicable to a vehicle driver, except special regulations and provisions that cannot apply. State traffic rules and valid local regulations still govern the ride.Wyoming Legislature — current Title 31 Spot an error? →
Bicycle-lane and paved-path access is unclear: current § 31-5-707 does not expressly authorize e-bikes on bicycle or multiuse paths, and § 31-5-704's designated-path wording speaks only of bicycles while § 31-5-102 defines a bicycle as solely human-powered. Check the responsible authority's rules and signs.Wyoming Legislature — current Title 31 Spot an error? →
Sidewalk access is unclear at the motor-off boundary: § 31-5-120 prohibits driving a vehicle other than by human power on a sidewalk except across a driveway, so motor-assisted sidewalk riding is not authorized. The cited section does not expressly name e-bikes or say whether riding one with its motor off changes the result; check local law and walk the bike when uncertain.Wyoming Legislature — current Title 31 Spot an error? →
Trail access is manager-controlled. Wyo. Stat. § 31-5-707 lets a local authority or state agency with jurisdiction regulate any e-bike class on trails, including natural-surface nonmotorized trails. Check the responsible manager's current rules and signs.Wyoming Legislature — current Title 31 Spot an error? →
A local authority may regulate e-bike operation on streets and highways under its jurisdiction and may require local e-bike registration or licensing, including a registration fee. A local authority or state agency with jurisdiction may also regulate any e-bike class on trails.Wyoming Legislature — current Title 31 Spot an error? →
Wyoming Game and Fish says that when the named Sheridan-region Wildlife Habitat Management Areas are open, all motorized vehicles, including e-bikes, must stay on established and marked roads; temporary road closures may also apply. The agency says WHMAs elsewhere have varying opening dates and times, so check the specific area.Wyoming Game and Fish — Sheridan-region WHMA access guidance Spot an error? →
05 / Common questions
No. Under Wyo. Stat. § 31-5-707(a) a qualifying e-bike operator is exempt from Title 31 provisions on driver's licenses, financial responsibility, state registration, and certificates of title, and an electric bicycle is not a motor vehicle — so no state driver's license, registration, title, or motor-vehicle insurance is required. A locality may still require its own e-bike registration or licensing and a fee under § 31-5-109(a)(vii).Wyoming Legislature — current Title 31 Spot an error? →
The cited current sources do not expressly answer yes or no. Wyoming's e-bike section contains no helmet clause, but statutory silence is not an express statewide adult exemption. Check local rules and wear one anyway.Wyoming Legislature — current Title 31 Spot an error? →
Roadway rights are stated, but the cited statutes do not expressly settle bicycle-lane or paved-path access for e-bikes. Natural-surface and other trail access is manager-controlled, and Wyoming Game and Fish restricts e-bikes to established and marked roads on the named Sheridan-region WHMAs when open.

Yes, as Class 2, if it otherwise meets Wyoming's e-bike definition and cannot provide assistance when it reaches 20 mph. A throttle-assisted device that assists at or above 20 mph does not fit the Class 2 definition.Wyoming Legislature — current Title 31 Spot an error? →
Unless another penalty or felony classification applies, § 31-5-1201 makes a violation a misdemeanor: up to $200 for a first conviction, up to $300 for a second conviction of the same offense within one year, and up to $500, up to six months' imprisonment, or both for a third or later same offense within the stated one-year period.Wyoming Legislature — current Title 31 Spot an error? →
