How Fast Can an Electric Bike or Ebike Go? Limits by Country

Most electric bikes stop helping you at 15.5 mph in the UK and EU, 20 mph in the US and Canada, and 28 mph for a Class 3 e-bike where your state allows one. That cap is where the motor's assistance ends, not the fastest you can ever travel. You can pedal past it, coast down a hill faster, or break the law with a modified bike, and real riders spend most of their time well below it.

So how fast can an electric bike or ebike go? It depends on where you live, which class your bike belongs to, and what you're really asking: the legal motor limit, the number on the spec sheet, or the speed you'll actually hold on a commute. This guide keeps those three apart, and every limit I quote is linked to the law, the agency or the study behind it.

A note on how I put this together. I haven't ridden every e-bike on the market and I won't pretend I have. I read the statutes, government and fire-service guidance, news reporting and published speed studies, and I link each one where I use it. Where something is my own opinion, I say so. Last checked October 5, 2026. Laws change, so confirm the rules where you ride.

Top speeds by country at a glance#

Before the details, here is the quick map. These are the assistance limits that define a legal "regular" e-bike in each place. Faster or stronger machines usually fall into a different vehicle class with different rules.

The Canada, Australia and Japan rows come from the same Wikipedia roundup of e-bike laws. It's a secondary source with a note that its detail is very dense, so use it as a map and check your own authority before you buy or ride.

How fast can e-bikes go in the US? Class 1, 2 and 3#

The US has a federal baseline and a state-by-state layer on top. The federal part is short. Congress defined a "low-speed electric bicycle" as a two- or three-wheeled vehicle with fully operable pedals and a motor under 750 watts, whose top speed on a paved level surface, powered only by that motor and ridden by a 170-pound rider, is under 20 mph. That definition matters mostly for how the product is regulated when it's sold.

Where you can ride and how fast is up to the states. Many of them use a three-class system modeled on California's. Wikipedia's summary of the California definitions lays it out like this:

1. Class 1. The motor helps only while you pedal, and assistance stops at 20 mph.
2. Class 2. The motor can power the bike on its own, typically with a throttle, and assistance stops at 20 mph.
3. Class 3. The motor helps only while you pedal, assistance stops at 28 mph, and the bike must have a speedometer.

So the straight answer for most of the US is that an e-bike's motor tops out at 20 mph, or 28 mph for a Class 3. How fast can e-bikes go in the US beyond that depends on you: pedaling harder, riding downhill or having a tailwind can take you past the cutoff, just without the motor's help.

Three details trip people up:

• Paths and trails. In California, local governments can allow or ban any class on dedicated bicycle paths, and by default Class 1 and 2 are allowed while Class 3 is not. Other states differ.
• Age. Washington State, for example, requires Class 3 riders to be at least 16.
• Not every state follows the system. Massachusetts doesn't use the Class 3 definition, and New Jersey treats e-bikes that can reach 20 to 28 mph as motorized bicycles that need a driver's license and registration, according to the same Wikipedia roundup.

Several states also require the maker to attach a permanent label showing the class, top assisted speed and motor wattage. In California, if you tamper with the bike and change its speed capability, you have to replace that label. I'll come back to that when we get to speed modifications. If you want the full class breakdown, I explain it in e-bike classes explained.

How fast does an ebike or electric bike go in the UK and Europe?#

The UK and most of Europe use a much lower number than the US, and the difference surprises people who buy a US-style bike abroad.

In the UK, an e-bike has to be an electrically assisted pedal cycle (EAPC) to be treated like a normal bicycle. The London Fire Brigade's guide to UK e-bike laws gives the two core conditions: the motor can have a maximum continuous power of 250 watts, and electric assistance must cut off at 15.5 mph (25 km/h). It also says the minimum age to ride on public roads is 14 and that there's no legal requirement to wear a helmet on a bike that meets the EAPC rules.

The EU uses almost the same numbers. According to Wikipedia's pedelec article, the EU exempts pedal-assisted cycles from type approval, registration and insurance if the motor is 250 watts or less and assistance is progressively reduced and cut off before 25 km/h. The Library of Congress's legal monitor summarizes the flip side: under EU Regulation 168/2013, all e-bikes except pedelecs with assistance up to 25 km/h and 250 W are subject to type approval.

That's where speed pedelecs come in. These are e-bikes with assistance up to 45 km/h (about 28 mph), the European cousin of the US Class 3. In several countries, including the Netherlands and Belgium, they're classed as mopeds rather than bicycles. The Library of Congress report notes that the Netherlands would treat fast e-bikes up to 45 km/h as mopeds from 2017, and the Wikipedia roundup says the same of Belgium's speed pedelecs. In Germany, Wikipedia's comparison table lists speed pedelecs at 45 km/h with a minimum rider age of 16, an insurance plate, and no access to bike paths.

So how fast does an ebike or electric bike go in the UK and Europe? Fifteen and a half mph with motor help on a standard bike, and up to about 28 mph on a speed pedelec that comes with moped-style requirements.

Canada, Australia, Japan and beyond#

A few other places are worth knowing, mainly because bikes get shipped around the world.

• Canada. The same Wikipedia roundup says all eight provinces that allow electric power-assisted bicycles limit them to 500 W and 32 km/h (20 mph) on motor power alone on level ground. A 750 W US bike can fall outside that definition.
• Australia. The pedelec category follows the European standard EN 15194: 250 W, with assistance cutting out above 25 km/h. The rules are still moving. The roundup says that from March 2029 only EN 15194-certified e-bikes will be road legal in New South Wales.
• Japan. Assistance is reduced as you speed up and is zero above 24 km/h (about 15 mph).

The pattern is clear. In the UK, the EU and Australia, 25 km/h is the ceiling for a bike that counts as a bicycle, and anything faster is a different legal vehicle.

How fast do e bikes usually go in real life?#

A top speed on a spec sheet is the most the motor will help. It isn't how fast people ride. Real riding is full of traffic lights, junctions, shared paths and hills.

Two pieces of research give a sense of scale. The German Naturalistic Cycling Study measured the speeds of 90 participants on conventional bicycles, pedelecs (assisted up to 25 km/h) and S-pedelecs (assisted up to 45 km/h). According to the study abstract, pedelec riders were on average 2 km/h faster than cyclists on conventional bikes, and S-pedelec speeds were 9 km/h higher. The highest speeds were measured on roads and cycling infrastructure, whatever the bike. Two kilometers an hour is only about 1.2 mph.

Portland State University's TREC summary of e-bike speed research adds more context. It reports that conventional cyclists on various bike facilities averaged around 12 to 15 mph, with maximums of 24 to 25 mph. In a University of Tennessee e-bike share study, e-bike average and maximum speeds were about 3 mph higher than conventional bikes. On shared-use paths, though, conventional riders were slightly faster on average than e-bike riders (7.8 mph versus 6.8 mph).

My reading of this: how fast do e bikes usually go? Closer to a fit cyclist's pace plus a few miles an hour than to the headline number. And how fast is an electric bike or e bike on an ordinary commute? Usually well under its cutoff. The cap tells you the ceiling, and your route tells you the average. If you want to know how long a commute will take, use your own distance and the speed of the roads you'll use, not the limit.

What decides how fast your e-bike goes#

Two e-bikes with the same legal class can feel very different. These are the things that decide how fast yours actually goes.

• The class or software limit. The motor stops assisting at the programmed cutoff. A bike limited to 15.5 mph doesn't have a faster mode waiting in a drawer.
• Motor power. More watts help with acceleration and hills. They don't raise the cutoff. A strong motor on a Class 1 bike still stops helping at 20 mph.
• Battery. A tired battery can reduce how hard the motor pulls, so a bike that reaches its limit at full charge may struggle to at the end of a ride. Cold weather can also affect it.
• You and your load. Heavier riders, cargo and child seats take more power to move.
• Hills, wind and surface. This is the big one at higher speeds. According to Wikipedia's article on bicycle performance, air drag increases with the square of speed, so the power needed climbs faster than the speed does. That's why a headwind or an upright riding position costs you far more at 20 mph than at 10.
• Tires and pressure. Wider, softer or knobby tires roll with more resistance than slick ones. Stay inside the pressure range your tire and bike maker specify.
• Assist level and gearing. A low assist setting or the wrong gear can leave the motor out of its best range, especially on mid-drive bikes.

If you're comparing bikes, my advice is to look at the class and the stated assisted speed first and the motor wattage second. If you want to see the most powerful and fastest machines on the market, I keep that list in fastest and most powerful electric bikes, and the single fastest one is covered in how fast the fastest ebike on the market goes.

How fast can an e-bike go without pedaling?#

If a bike has a throttle, how fast can it go on motor power alone? The legal answer is the same as for the class. A Class 2 e-bike's motor can power the bike on its own, but assistance stops at 20 mph. The federal definition caps motor-only speed under 20 mph as well. Class 1 and Class 3 bikes need you to pedal to get any help.

The UK is stricter. The Isle of Anglesey County Council's trading standards guidance says an electric bike that can be propelled without pedaling, a "twist and go", has to be type approved, as does any bike that doesn't meet the EAPC rules. In other words, a throttle-only bike generally isn't a normal UK bicycle.

Top speed without pedaling depends on the throttle and class, and I go through the details in how fast e-bikes go without pedaling.

How fast do motorized bikes go? And what about Lectric ebikes?#

Two other phrases show up next to e-bike speed searches, and neither is quite the same thing.

How fast do motorized bikes go? "Motorized bike" usually means a bicycle with a small gasoline engine, not an e-bike. Laws for these generally define them by engine size and design speed. According to the state-by-state table in Wikipedia's e-bike laws article, the caps sit around 25 to 30 mph in places like Louisiana (25 mph) and Kentucky (30 mph), and they often come with registration or licensing rules that e-bikes avoid. If you meant a gas-powered motorized bike, check your state's moped and motorized-bicycle rules, because the e-bike classes above don't apply.

How fast do Lectric ebikes go? Lectric is a brand name, and the speed depends on the model and its class, so there isn't one answer I can give for the whole line. The reliable way to find out is the label on the bike and the spec sheet for your exact model, which I cover below. The same advice goes for any brand: how fast do Lectric ebikes go, or any other maker's, comes down to the class, the programmed cutoff and the local law, not the brand.

Can you make an e-bike faster?#

Yes, but it's worth separating the legitimate ways from the ones that put you on the wrong side of the law.

Legitimate ways to go a bit faster

• Charge the battery fully and keep it in good shape.
• Reduce load: carry less cargo and check tire pressure against the maker's range.
• Use a higher assist level and the right gear, so the motor works where it's strongest.
• Fix the drag: a more tucked or less upright position, and removing bulky racks and bags you don't need.
• Pedal. Above the cutoff the motor won't help, but you can.
• If it's legal where you live and you want faster assistance, buy a Class 3 bike or a speed pedelec, and follow the extra rules that come with it.

Ways that get people into trouble

Removing or defeating a speed limiter is the one I'll warn you about. In the UK, the Isle of Anglesey guidance says the Department for Transport is aware of bikes limited to 15.5 mph that have off-road switches or modes letting the motor keep assisting beyond that. Any e-bike that doesn't meet the EAPC rules is classed as a motorcycle or moped, which needs to be registered and taxed, and the rider needs a driving licence and a motorcycle crash helmet.

The news coverage shows how seriously it's enforced. An LBC report on police seizures of e-bikes says many illegal e-bikes taken by police have been modified, with some exceeding 70 mph. It adds that non-compliant machines are effectively electric mopeds or motorbikes that must be registered, taxed and insured, and that forces have started using portable rolling-road devices to test a bike's maximum motor speed.

In the US, tampering has its own consequences. California requires the class label to be replaced if you change the bike's speed capability, and in some states a bike that goes beyond the class limits is treated as a moped or motorized bicycle, with licence and registration requirements. New Jersey is one example. I'm not going to explain how to remove a limiter, and I'd steer you away from anyone who offers to do it. Insurance and liability after a crash on an illegally modified bike are a risk I wouldn't take.

How fast is too fast? Safety at speed#

Speed isn't the only thing that changes your risk, but it's a big one. The authors of the German study cited above note that e-bikes reach higher speeds than conventional bicycles regularly, and that although it's unclear whether this increases crash risk, the consequences of a crash might be more severe on average. They also found the highest speeds on roads and cycling infrastructure, where you're most likely to meet faster traffic and other riders.

A few habits I'd adopt, which are my own advice and not a legal standard:

• Ride to the conditions, not the limit. A Class 3 can assist to 28 mph. That doesn't mean a crowded shared path is the place for it.
• Check your brakes before you check your speed. Stopping from a higher speed takes longer, so keep pads and cables in good condition.
• Wear a helmet. Helmet laws differ by place and class, and I'd wear one regardless.
• Be visible. Lights and reflective gear matter more as speeds go up.
• Know the path rules. Some paths ban the faster classes entirely, and local speed limits for bikes can be lower than your bike's cutoff.

How to find your own e-bike's top speed#

Don't guess. The most reliable way to find out how fast your bike is allowed to go with motor help is to read it off the bike.

1. Look for the label. In several US states, including California, Illinois and Washington, e-bikes must carry a permanent label showing the class, the top assisted speed and the motor wattage.
2. Read the manual and spec sheet for your exact model, year and market, and make sure it matches the bike you actually own.
3. Check the display or app. Many bikes show the assist limit in a settings menu. Don't change it to something above your legal class, because that can affect your legal status and warranty.
4. Confirm the local rule. A US-market Class 3 may not be legal for road use in the UK or EU, and a UK bike limited to 15.5 mph may feel slow in the US.
5. Test it safely. On a flat, empty, legal stretch with good brakes, a bike computer or GPS speed readout will show where assistance fades. Do it somewhere you're allowed to ride at that speed.

How e-bike speeds compare with scooters and skateboards#

Electric bikes, scooters and skateboards all use speed limits, but they're not interchangeable. An e-bike's limit is a legal category tied to pedals and class. Scooters and skateboards have different rules, different top speeds and different failure modes. If you're weighing options, my guides on how fast electric scooters go and how fast electric skateboards go cover each one on its own terms.

Frequently asked questions#

How fast can an electric bike or ebike go?#

Most stop assisting at 15.5 mph in the UK and EU, 20 mph in the US and Canada, and 28 mph for a Class 3. You can go faster by pedaling, going downhill or modifying the bike, but the last of those can make it illegal.

How fast does an ebike or electric bike go in real life?#

Usually close to a fit cyclist's pace plus a few mph. A German field study found pedelec riders about 2 km/h (1.2 mph) faster on average than conventional cyclists.

How fast is an electric bike or e bike compared with a regular bike?#

Slightly faster on average, and much easier to hold at speed. Research summarized by Portland State found e-bike riders about 3 mph faster on average in one university program, though slower than conventional riders on some shared paths.

How fast do e bikes usually go on a commute?#

Closer to their riders' normal pace than to their limit. Traffic lights, junctions and shared paths keep the average well below the cutoff.

Can an e-bike go 28 mph?#

Yes, a Class 3 e-bike in the US can assist up to 28 mph, and speed pedelecs in Europe assist up to 45 km/h (about 28 mph). Both usually come with extra rules.

Is 20 mph fast for an e-bike?#

It's the most common US limit for Class 1 and Class 2. It's faster than most people ride a regular bike, but it's well within what e-bikes are built to do.

How fast can an e-bike go without pedaling?#

On a Class 2 bike with a throttle, up to 20 mph in the US. In the UK, a bike that can run without pedaling generally needs type approval.

Will a more powerful motor make an e-bike faster?#

It makes it accelerate and climb better, but it doesn't raise the legal cutoff. A strong motor on a Class 1 bike still stops helping at 20 mph.

Does the battery affect top speed?#

It can. A low battery or very cold weather can reduce how hard the motor pulls, so you may not reach your limit late in a ride.

How fast do motorized bikes go?#

Gas-powered motorized bikes are regulated separately, with design-speed caps of roughly 25 to 30 mph in some states, such as Louisiana and Kentucky.

How fast do Lectric ebikes go?#

It depends on the model and class. Check the label and the spec sheet for your exact bike rather than relying on the brand name.

Do e-bike speed limits differ by country?#

Yes. The UK and EU use 15.5 mph (25 km/h), the US uses 20 or 28 mph depending on class, and Canada uses 20 mph (32 km/h).

Can I raise my e-bike's speed limit legally?#

Only by choosing a bike in a higher legal class, such as a Class 3, where your area permits it. Changing the programmed limit on a bike can put it in a different legal category.

The bottom line#

So, how fast can an electric bike or ebike go? For most riders, the honest answer is 15.5 mph with motor help in the UK and Europe, 20 mph in the US and Canada, and 28 mph if you buy a Class 3 where it's allowed. Your actual speed will usually be lower, because streets, hills and shared paths set the pace.

Check the label on your bike, read the rules where you ride, and treat the cutoff as a legal and safety boundary, not a target. If you want to see how the fastest machines stack up, start with fastest and most powerful electric bikes.
