Ebike Motor Power Legal Checker

The Ebike Motor Power Legal Checker answers the question every ebike owner eventually asks: is my motor actually street legal here? You enter the continuous rated power, the top assisted speed, whether there is a throttle and whether there are working pedals — and it returns the legal class your bike falls into, plus a twelve-region legality passport showing where the same bike would be a bicycle, where it would be a moped, and where it would be nothing at all.

The Four Numbers That Decide Everything

Almost every ebike law in the world is built from the same four tests. Once you know your four values, the verdict in any country is mechanical.

Rated Power vs Peak Power: The Trap Almost Every Listing Sets

A motor advertised as "750 W peak" and a motor rated at 750 W continuous are completely different machines in the eyes of the law. Every jurisdiction in this checker regulates continuous rated power, the figure printed on the motor label and quoted in the manual. Peak power is a marketing number describing a few seconds of overload during a hill start.

This cuts both ways. A 250 W rated motor that peaks at 600 W is a perfectly legal European pedelec, and the peak figure changes nothing. But a bike sold as "500 W" without saying which figure it means may be a legal Canadian bike or an illegal one depending on a word nobody printed. If the listing only gives you a peak number, ask the seller for the rated figure in writing before you buy — that document is what you would show at a roadside stop or an insurance claim.

Class 1, Class 2 and Class 3 in Plain English

Most of the United States uses a three-class system, all capped at 750 W:

• Class 1 — pedal assist only, help stops at 20 mph (32 km/h). The most widely welcomed class; usually allowed anywhere a normal bicycle is.
• Class 2 — throttle allowed, help still stops at 20 mph. Some parks and natural-surface trails admit Class 1 but not Class 2.
• Class 3 — pedal assist only, help continues to 28 mph (45 km/h). Usually 16-and-over with a helmet, and often barred from shared-use paths.

The most common way a bike escapes all three at once is a throttle that still works above 20 mph. That combination fits neither Class 2 (too fast) nor Class 3 (throttle not allowed), so the bike lands outside the system entirely. New York is the notable exception: its Class 3 stops at 25 mph and does permit a throttle, but only inside New York City.

Ebike Power and Speed Limits by Region

Read this table as a summary of headline national rules, not as the whole law. States, provinces, cities and individual land managers add their own conditions on top, especially about helmets, minimum ages and which paths a Class 3 or throttle bike may use.

What Happens When a Bike Falls Out of Class

Falling outside the bicycle definition rarely means the machine is banned. It usually means it has been reclassified as a moped or a light motorcycle, and the obligations that come with that are the real cost: registration and a number plate, third-party insurance, a moped or motorcycle licence, an approved helmet, and a ban from cycle paths. In the European Union that is the L1e-A and L1e-B categories; in the United Kingdom it is a moped; in most of the United States it is a motor-driven cycle under state law.

The practical consequences show up in three places: an insurance claim after a collision, a police stop where the bike is impounded, and a customs inspection when the bike is imported. All three come down to paperwork about the rated power, which is why the label matters more than how fast you actually ride.

Common Mistakes That Make a Legal Ebike Look Illegal

1. Quoting the peak watts. Telling an officer or an insurer that your bike is "a 1000 W" when the motor is rated 250 W hands them a number the law never asked for. Learn the rated figure and say that one.
2. Confusing top speed with assist cut-off. A pedelec that coasts to 45 km/h downhill is still a 25 km/h pedelec. Only the speed at which the motor stops helping counts.
3. Assuming a dongle or a de-restriction menu is harmless. Raising the cut-off past the legal speed reclassifies the bike, which usually voids the insurance and the manufacturer warranty at the same time.
4. Buying abroad without checking the class. A 750 W throttle bike is ordinary in the United States and unrideable on any public road in the European Union, the United Kingdom or Singapore.
5. Forgetting the pedals. Fitting a seat and pegs and removing the cranks turns a bicycle into a moped in every region on this page, no matter how small the motor is.
6. Treating a national rule as the whole rule. States, provinces and cities add helmet rules, age minimums and path bans on top. Being within the wattage limit is necessary, not sufficient.

How to Use This Checker

1. Choose your region: Pick the place you actually ride from the Region I Ride In list. Every one of the twelve regions is checked regardless, but this one gets the legality map and the full category table.
2. Enter the continuous rated power: Use the number on the motor label or in the manual, not the peak figure from the advertisement. The live badge updates as you type.
3. Add the peak power if you know it: Optional, but it lets the checker flag the rated-versus-peak mismatch that trips up so many buyers.
4. Enter the top assisted speed: The speed at which the motor stops helping, in km/h or mph. Coasting downhill faster than this does not count.
5. Describe the throttle and pedals: Be honest about whether the throttle moves the bike without pedalling — that one answer changes the verdict in half the world.
6. Click Check Legality: You get your class, the binding constraint, the smallest change that would fix it, and the twelve-region passport.

Frequently Asked Questions

How many watts is street legal for an ebike?

It depends entirely on where you ride. The United States allows up to 750 W of continuous rated power, Canada 500 W, China 400 W, New Zealand 300 W, and the European Union, United Kingdom and Singapore only 250 W. Australia allows 250 W with no throttle or 200 W with a throttle. Japan sets no wattage limit at all and regulates the assist ratio instead.

What is the difference between rated power and peak power on an ebike?

Rated power is the power a motor can sustain continuously without overheating, and it is the number every law on this page regulates. Peak power is the short burst a motor can produce for a few seconds when starting or climbing, and it is the number used in advertising. A motor rated 250 W that peaks at 600 W is still a legal pedelec in the European Union.

What are Class 1, Class 2 and Class 3 ebikes?

Class 1 is pedal assist only with help stopping at 20 mph. Class 2 adds a throttle but still stops at 20 mph. Class 3 is pedal assist only with help continuing to 28 mph, usually with a helmet requirement and a minimum rider age of 16. All three are capped at 750 W. New York is the main exception, where Class 3 stops at 25 mph and may use a throttle.

Is a 1000W ebike legal?

Not as a bicycle in any of the twelve regions checked here. A 1000 W continuous rated motor is above the 750 W United States ceiling, the 500 W Canadian limit and the 250 W European limit. In the European Union a 1000 W machine can only be registered as an L1e-A powered cycle, which needs type approval, insurance and usually a moped licence. Some United States states allow it strictly off road on private land.

Why is a throttle illegal in Europe but fine in the United States?

European law defines a pedelec as a bicycle whose motor only responds to pedalling, so any throttle that moves the bike without pedalling turns it into a moped needing registration. A 6 km/h walk-assist button is the one permitted exception. United States Class 2 was written specifically to legalise throttles up to 20 mph, and Canada, China and New Zealand also allow them.

Can I make my ebike legal by turning down the speed limit?

Often yes. If the only thing over the line is the assisted speed, restoring the controller or display speed setting to the legal cut-off brings the bike back into class, because the wattage and the pedals are unchanged. If the motor is rated above the local ceiling, no menu setting fixes it, because the law regulates the motor rating rather than how fast you actually ride.
