Each row is the statute's own content, reduced to plain wording where it is long and quoted directly where the exact words matter. The section in the last column is a link to the text.

What one costs today. The cheapest complete electric skateboard in stock at a shop we read is 38" Hurricane Electric Longboard Electronic Skateboard, at US$240 (the cheapest one, tracked daily). 34 boards under $500 · 94 under $1,000 — every price checked at the shop, not copied from an ad. The full picture, from entry boards to the top of the range: how much an electric skateboard costs.

Buying in the United States. Electric skateboards from the 254 shops we read there, priced in the currency they charge.

Deciding between a board and a single wheel? Onewheel or electric skateboard. A word in the texts above you do not know? The glossary.

The same four questions, across every jurisdiction whose primary sources we have read. Neighbouring jurisdictions link to their own page and citations; every other one is a click away on the full list.

The spread is the point. These are neighbouring jurisdictions regulating the same object, and they do not agree on what it is, how fast it may go, who may ride it, or whether it may be ridden at all. A rider who crosses a state line is, quite often, subject to a different legal category rather than a stricter version of the same one — which is why a single national answer to this question does not exist and why anyone offering you one has stopped reading the law.

It also explains why so many rows say the device is unaddressed. Most vehicle codes were written before this machine existed, and a legislature that has not revisited them has not thereby permitted anything — it has left the question to a general classification and to your city.

Allowed, as an EPAMD — not in bike lanes or on public paths. Seattle's municipal code defines the electric personal assistive mobility device to include “a self-balancing device with one wheel designed to transport only one person by an electric propulsion system with an average power of 2000 watts”, with a top speed under 20 mph (SMC 11.14.186 B). Under SMC 11.46.010 B, “EPAMDs may be operated on roadways, shoulders, sidewalks, and alleys, but not on bicycle lanes, or public paths.”

Every jurisdiction that names a one-wheel board, side by side: Are Onewheels legal?

• It is not legal advice, and it never says you may ride. It says what the statute says, and links it.
• It does not repeat Washington law. The city's rules sit on top of it; read that page too. Park, transit and campus rules can add more.
• It does not cover private property, insurance, or what happens after an accident.
• It may be out of date. Every source carries the day we read it. A statute amended since then will not have updated itself here.

Across the border: Washington. Every other jurisdiction: the full list.

Are electric skateboards legal in Seattle?

No law we can find defines an electric skateboard. What applies instead is a general vehicle classification and, in practice, your municipality. No Seattle text we read names the electric skateboard. The closest definition, the motorized foot scooter (SMC 11.14.333), needs no handlebars but is limited to a device “with two or three wheels that has a floorboard”, which leaves a four-wheel board outside its words; SMC 11.46.040 extends it only to other wheel sizes. The city's skateboard rules are quoted below (sidewalks, SMC 11.40.255; arterial streets, SMC 11.40.250; parks, SMC 18.12 and 18.16.150); the code does not define the skateboard and does not say whether those rules reach a powered board. Washington State law also applies on top of these city rules; see the Washington page.
