TL;DR:
Washington kept its three-class e-bike system. A true Class 1, 2, or 3 e-bike (pedals, 750 watts or less) still needs no license, registration, or insurance. Since June 11, 2026, anything that tops 20 mph on throttle alone, or was sold to be easily unlocked, is legally a motorcycle or moped, which for most means a license with endorsement, registration, insurance, and a DOT helmet. A state work group reports on full e-moto rules December 15.
Published September 2026. Engrossed Substitute Senate Bill 6110 (Chapter 159, Laws of 2026) took effect June 11, 2026. Verify current requirements with the Washington State Department of Licensing at dol.wa.gov before you buy, sell, or modify a bike.
Governor Bob Ferguson signed Engrossed Substitute Senate Bill 6110 on March 23, 2026. It is now Chapter 159, Laws of 2026. The section creating the work group took effect the day he signed it. The new e-bike definition took effect June 11.
Washington did not build a licensing system for electric motorcycles this year. It did something narrower and faster. It rewrote the e-bike definition so the machines that were never bicycles stop borrowing a bicycle's legal status, and it handed the harder questions (fees, minimum ages, youth penalties, marketing rules) to a work group that reports over the next 13 months. For commuters, the law is short and clear. For families with a teenager and an electric dirt bike in the garage, a lot of it is still being written.
What Triggered This Law
Electric dirt bikes spread through Washington neighborhoods faster than the law could sort them out. Harborview Medical Center in Seattle treated 252 people for e-bike and e-scooter injuries in 2025, more than three times as many as in 2021, and its doctors name speed as a major factor. Police from Snoqualmie to Pierce County kept stopping teenagers on machines that, in the words of one sheriff's spokesperson, "closely resemble and perform similarly to gas-powered dirt bikes."
Sen. Sharon Shewmake of Bellingham carried the bill. Lawmakers heard that e-motos are routinely sold as e-bikes and that many parents buying them have no idea they are not bicycles. Bike advocates, cities, and park agencies all backed it, nobody testified against it, and it passed both chambers by wide margins.
A month after the law took effect, a 14-year-old was killed riding an electric motorcycle at a Seattle bike park.
The New Categories
Washington did not create a new "e-moto" category. It tightened the e-bike definition and let everything that falls outside it land in categories that already existed.
Electric-assisted bicycle. Two or three wheels, a saddle, fully operative pedals for human propulsion, and an electric motor of no more than 750 watts. Class 1 assists only while you pedal and stops at 20 mph. Class 2 can move the bike on throttle alone and stops assisting at 20 mph. Class 3 assists only while you pedal, stops at 28 mph, and must have a speedometer. These are still bicycles for nearly every purpose under Washington law.
What no longer counts. The new law adds two exclusions. A vehicle is not an e-bike if it can exceed 20 mph solely on its electric motor. And it is not an e-bike if it was "designed, manufactured, or intended by the manufacturer or seller to be easily configured" to fall outside the e-bike requirements through a mechanical switch or button, a change in the software settings controlling the drive system, or an online app.
Read that second exclusion closely. It is written about how the bike was designed and sold, not about whether you ever flipped the switch. A bike that shipped with an "off-road mode" behind an app toggle arguably fails the definition while it sits in your garage, unused. No court has tested that reading yet, but it is the language an officer, a prosecutor, or an insurance adjuster will look at after a crash.
Motorcycle and moped. Everything that fails the e-bike definition falls under these existing categories. The Legislature said so directly: current definitions of motorcycle and moped apply to many of the vehicles now excluded from the e-bike definition. A moped in Washington is limited to 50 cubic centimeters, two brake horsepower, and 30 mph on level ground. Anything bigger or faster is a motorcycle. A lower-powered motorcycle of five brake horsepower or less is a "motor-driven cycle," a subcategory that carries slightly different rules.
Those definitions were written for gas engines, and they still speak in cubic centimeters and horsepower. Two brake horsepower works out to roughly 1,500 watts and five to roughly 3,700, but the statutes do not say how an electric motor's rating should be measured, and manufacturers of these machines often advertise peak output rather than continuous. Sorting that out is one of the first jobs the work group has.
If You Ride an Ordinary E-Bike
Class 1, 2, and 3 owners keep the legal simplicity of a bicycle. No driver's license. No registration. No plate. No insurance mandate. The law was written to protect that, and bike advocates backed it for that reason.
Check your label. Washington already required manufacturers to permanently attach a label listing the bike's class, top assisted speed, and motor wattage, and to meet federal bicycle safety standards. If your bike has no label, or the numbers on it do not match what the bike does, that is the first sign you may own something the state no longer considers an e-bike.
Don't unlock it. Tampering with an e-bike to change its speed capability without replacing the label was already prohibited. The new definition raises the stakes. If your bike can be made to exceed 20 mph on throttle, or was sold to be easily reconfigured, it stops being a bicycle and becomes a motorcycle or moped in the eyes of the law, with everything that comes with that.
Age. Riders under 16 may not operate a Class 3 e-bike. Washington has no statewide minimum age for Class 1 or Class 2.
Helmets. Washington has no statewide helmet requirement for bicycles or e-bikes at any age. King County repealed its all-ages bicycle helmet rule in 2022, which also ended the requirement in Seattle. A few cities still have local rules, so check where you ride. Whatever the law says, a helmet is the single most effective piece of gear you can wear on an e-bike.
Sidewalks and paths. Class 1 and Class 2 e-bikes may use shared-use paths and any part of a road designated for bicycles. Class 3 bikes may not ride on shared-use paths unless the local jurisdiction allows it, and riding a Class 3 on a sidewalk is unlawful unless there is no alternative. Local governments can restrict sidewalk riding further, and many downtowns do.
Trails. No e-bike of any class may be ridden on a trail specifically designated as nonmotorized with a natural surface, unless the agency that manages the trail allows it. State Parks, the Department of Natural Resources, and local park agencies each set their own policies, so check before you load up for a trailhead.
If You Ride an E-Moto
If your machine has no pedals, has a motor over 750 watts, or goes faster than 20 mph on throttle alone, Washington already treats it as a motor vehicle. The new law did not create those requirements. It removed the ambiguity that let sellers and riders pretend they did not apply.
According to the Department of Licensing, riding an electric motorcycle on a public road requires:
A license with a motorcycle endorsement. An ordinary driver's license is not enough for a motorcycle. You need the endorsement, which means a knowledge test and a skills test or an approved training course. Since a driver's license starts at 16, so does legal road riding.
Registration and a plate. The machine has to be titled and registered with the state.
Insurance. Washington requires liability coverage on registered motorcycles.
A DOT-approved helmet. Washington's motorcycle helmet law applies to every rider and passenger, at every age.
Road equipment. Headlight, brake light, turn signals, and mirrors, at a minimum.
E-motos are also barred from the places riders most want to take them. Mopeds are barred by statute from bike paths, bikeways, and hiking or recreational trails, and neither mopeds nor motorcycles may be ridden on sidewalks. Off-road, they belong on private property with the owner's permission or in parks and trail systems that allow dirt bikes.
Riding one on a public road without a valid license is a criminal matter, not a traffic ticket. Driving without a valid license in Washington is a misdemeanor carrying up to 90 days in jail and a $1,000 fine. Police in Snoqualmie, Mercer Island, and Pierce County have all used impoundment, and Carly Cappetto of the Pierce County Sheriff's Office explained why: "The loss of access to an offending vehicle may prove to be one of the most effective deterrents for both riders and parents."
Can You Make an E-Moto Street Legal?
Possibly, and that is more than riders in many states can say. Washington has an established process for converting an off-road motorcycle for highway use. You add the required equipment (headlamp, tail lamp, stop lamp, reflectors, mirrors on both sides, a horn, street-rated tires, turn signals, and fenders), have it inspected by a licensed Washington motorcycle dealer or repair shop for no more than $100, and submit an Off-Road Motorcycle Highway Use Declaration with the inspection receipt and the title at a vehicle licensing office. Your title and registration come back marked "modified for on-road use," along with a motorcycle plate and an off-road decal.
The catch is the title. The conversion process starts from a titled motorcycle. Many electric dirt bikes were imported and sold as bicycles, and they may have come without a manufacturer's certificate of origin or a vehicle identification number. Without those, there is nothing to title, and the conversion has nowhere to start. Before you buy, ask the seller for the certificate of origin and look for a VIN on the frame. If neither exists, assume the machine will only ever be legal off-road.
What the Work Group Will Decide
The piece of this law with the longest reach took effect first. The Department of Licensing must convene a work group to recommend a full statutory framework for electric motorcycles. Its members include the Department of Transportation, the Washington Traffic Safety Commission, the State Patrol, the Cooper Jones Active Transportation Safety Council, the Association of Washington Cities, the Washington State Association of Counties, e-bike safety and trails organizations, motorcycle riders, a tribal government, a statewide recreational e-moto group, and a parks association.
The group has to make recommendations on how e-motos should be defined and classified, whether they should carry annual registration and license fees, driver education and minimum age requirements, rules of the road, equipment standards, and enforcement. Two items will get the most attention from parents. The group must explore civil infractions that local governments could impose on juveniles between 12 and 16, and civil penalties for adults who provide e-motos to anyone under 16. Right now, witnesses told lawmakers, juvenile court is the only tool available when a child rides one illegally.
It also has to look at penalties for deceptive marketing and tampering and at consumer disclosure requirements, which is the part aimed at the sellers who list 5,000-watt machines as "e-bikes."
The interim report, covering definitions, registration, licensing, and rules of the road, is due December 15, 2026. The final report is due October 31, 2027. The earliest the Legislature could act on the interim recommendations is the 2027 session.
Your City May Already Have Rules
ESSB 6110 does not preempt local e-bike or e-moto rules, and several cities did not wait for the state.
Mercer Island adopted its e-motorcycle ordinance unanimously in September 2025, and it took effect January 1, 2026. It covers any electric machine with a motor over 750 watts, one that keeps propelling itself at 28 mph or more, or a dirt-bike-style frame without operable pedals. Riders need a motorcycle-endorsed license and a plate, and the machines are banned from sidewalks, pedestrian paths, and public parks. Fines run $250 for a first offense, $500 for a second, and $750 after that, with impound available. "The proposed legislation...is to fill that gap and give us at least something we can do," police Commander Mike Seifert told the council.
Sammamish police spell out the same road requirements (plate, lights, turn signals, mirrors, endorsement, insurance, DOT helmet, age 16) and limit everything else to private property or parks that allow dirt bikes. Snoqualmie has been impounding bikes since 2025. If you ride on the Eastside or in south Puget Sound, check your city's code before you assume the state law is the whole story.
What the Law Does Not Do
No e-moto framework yet. Washington is regulating e-motos under definitions written for gas mopeds and motorcycles decades ago, and it will keep doing so until the Legislature acts on the work group's recommendations.
No helmet requirement for e-bikes. A 28 mph Class 3 e-bike carries no helmet requirement anywhere in state law, for riders of any age.
No age floor for Class 1 and Class 2. A 10-year-old may legally ride a 20 mph throttle e-bike under state law, subject to local rules.
No new penalties for sellers. The law narrows what counts as an e-bike, but it sets no fine for marketing an electric motorcycle as one and requires no point-of-sale warning. Both are on the work group's list.
No impairment rule for e-bikes. Washington's DUI statute does not reach bicycles, and e-bikes are treated as bicycles. The state's intoxicated-bicyclist law lets an officer offer an impaired rider a ride home and impound the bike, which must be returned without a fee. E-motos, as motor vehicles, fall under DUI law in full.
No money. The bill carries no appropriation for enforcement, education, or crash data.
The Insurance Reality
For Class 1, 2, and 3 riders in Washington, nothing legally obligates you to carry coverage. That has never been the reason to have it.
An e-bike is a $2,000 to $8,000 machine that spends half its life outside your house, and bike theft is a constant in Seattle, Tacoma, and Spokane. Homeowners and renters policies handle e-bikes poorly: a low sublimit, a deductible that swallows most claims, little or nothing once the bike leaves your property, and very little Liability protection, which is the part that ruins people. A rider who hits a pedestrian on the Burke-Gilman is looking at medical bills and a claim that can run past six figures. And if a driver hits you and has no insurance, your own health plan may leave you with the rest. Velosurance writes dedicated e-bike policies covering theft and damage, plus Liability, Medical Payments, and Uninsured Motorist coverage, with limits well above anything a state requires.
For e-moto owners, the gap is wider. Most homeowners forms exclude liability arising from motorized vehicles, and the exclusion usually keys on whether the vehicle is designed for or subject to registration. Now that Washington has made clear these machines are motorcycles or mopeds, the argument that a homeowners policy should respond gets harder to make. A registered motorcycle needs its own motorcycle policy. Mopeds and motor-driven cycles are exempt from Washington's mandatory insurance law, but an exemption from the mandate is not coverage. If one of those machines injures someone, nothing responds unless you bought something that does.
The hardest case is the one many Washington families are in: a high-powered electric dirt bike with no title, no VIN, and no road equipment, bought online as an "e-bike" for a teenager. That machine cannot be registered, cannot legally be ridden on the road, and is likely not covered by anything the family already owns. The work group is also considering civil penalties for adults who provide e-motos to kids under 16. If that describes your garage, call your agent before the first claim, not after.
Frequently Asked Questions
- What do Class 1, Class 2, and Class 3 e-bike riders need to ride legally in Washington?
- A Class 1, Class 2, or Class 3 e-bike with fully operative pedals and a motor of no more than 750 watts rides like a bicycle in Washington: no driver's license, registration, plate, or insurance mandate. Class 1 assists only while you pedal and stops at 20 mph, Class 2 can move on throttle alone and stops assisting at 20 mph, and Class 3 assists only while you pedal, stops at 28 mph, and needs a speedometer. Riders under 16 may not operate a Class 3.
- What should you know about e-bikes with an app-unlockable speed mode in Washington?
- A bike stays an e-bike in Washington when it cannot exceed 20 mph solely on its electric motor and was not designed or sold to be easily configured outside the e-bike requirements through a switch, a software setting, or an online app. The caveat worth knowing: that second test looks at how the bike was designed and sold, so a bike that shipped with an app-toggled off-road mode arguably fails it even if you never use the mode. Outside the definition, it is a motorcycle or moped.
- What does it take to ride an electric motorcycle legally on Washington roads?
- You need a license with a motorcycle endorsement, a titled and registered machine with a plate, liability insurance, a DOT-approved helmet, and road equipment that includes a headlight, brake light, turn signals, and mirrors. Since a driver's license starts at 16, so does legal road riding. One thing to watch: riding one without a valid license is a misdemeanor carrying up to 90 days in jail and a $1,000 fine.
- How can an electric dirt bike become street legal in Washington?
- Washington lets you convert an off-road motorcycle for highway use: add the required road equipment, have it inspected by a licensed Washington motorcycle dealer or repair shop for no more than $100, and submit an Off-Road Motorcycle Highway Use Declaration with the inspection receipt and the title. With one wrinkle: the process starts from a title, and machines sold as bicycles often lack a certificate of origin or VIN. Check for both before you buy.
- Where can you ride Class 1, Class 2, and Class 3 e-bikes in Washington?
- Class 1 and Class 2 e-bikes may use shared-use paths and any part of a road designated for bicycles. Class 3 e-bikes may use shared-use paths where the local jurisdiction allows it, and ride on a sidewalk only when there is no alternative. One thing to watch: no e-bike of any class may ride a natural-surface trail designated as nonmotorized unless the agency that manages it allows it.
