How fast can an electric bike reach? legally or not

Best bike us

If you are interested in fast can an electric bike reach from the best bike us, it’s probably (among other things) for its speed. Indeed, in addition to not having to provide climbing effort, an electric bike is supposed to allow going quickly and reducing the travel time between housing and work.

So how fast can an electric bike really reach, what are the laws, and how can you increase the speed of your electric bike? In this article, I will answer each of these questions so that you can learn more about the speed of an electric bike.

How fast can an electric bike reach?

Although interesting, this question is about as vague as asking: how fast can a car reach?

Well, it depends on the car!

An Aixam can go up to 50 km/h, while a Tesla Model S 250 km/h.

For e-bikes, it’s exactly the same thing. Some have powerful engines and reach high speeds while others are made to go slower.

To date, one of the fastest electric bikes in the world available for purchase is the Stealth B-52, which reaches a ridiculously high speed of 80 km/h.

Suffice to say that at this speed, a helmet and protections worthy of a motorcycle are essential. And if you’re wondering what it’s like to ride at such a speed on this bike, take a look at this site and enjoy. Average weight of an electric bike the 4 most important factors

Speed, directly related to legislation

Well, you know now that an electric bike can run about as fast as you want as long as the engine is powerful enough. And in fact, that’s the problem: the power of the engine. Imagine being the lawmaker of a country and seeing these electric devices arrive capable of going as fast as motorcycles. How to regularize all this?

The option chosen by the European Union to solve this problem was to limit not only the power of the motor of the pedelecs but also their maximum speed.

Thus, the European directive on the subject indicates that a VAE must respect the following characteristics:

  • Electric assist must only work with pedaling
  • Electrical assistance must be cut above 25 km/h
  • The electric motor must have a power of fewer than 250 watts


If a bike meets all these points, then it is considered by law to be a pedelec and there is no need for a license, insurance or helmet to ride with. For all bikes that do not respect all these points, such as the more powerful and fast electric bikes, the manufacturer will have them homologated as mopeds. In addition, in order to ride with an electric moped, you must have a license, wear a helmet best bike us and be insured.

So, if you’ve already had a look at the electric bicycles available for purchase in stores, this is the European directive that is why almost all electric bikes are limited to 25 km/h.

How to ride faster on an electric bike?

For high-slope, short-haul urban uses, the power, and speed of pedelecs are usually sufficient, and you may think that 25 km/h is a speed that’s enough for your needs.

However, for many other uses, this limit in speed and power imposed by legislation is a real problem.

For example, imagine a 10-kilometer trip to your job.

If you ride a bike with a constant speed of 25 km/h, it would take you 24 minutes to reach your place of work. And that is with a constant speed of 25 km/h.

In other words, between the traffic lights, the climbs and the traffic around you, your average speed would rather be around 20 km/h than the 25, which would increase your travel time to a total of 30 minutes for only 10 kilometers distance. In the case of people living in cities with big slopes, the problem becomes not the distance but especially the engine power.

Indeed, 250 watts is not a very high power compared to the weight of the bike and the cyclist combined. So, while one of the main reasons for buying an electric bike is the lack of effort, people who have to climb steep slopes with a 250-watt motor are forced to do a lot of effort to get to the destination.

Finally, and in my opinion, a factor that is all too often forgotten, there is the question of fun.

I do not know you, but personally, when I travel by bike, I want it to be a pleasure and not a penance as car travel can so often be. I want to feel the wind on my face and be able to climb any side quickly and effortlessly. I want people, seeing me, say: “wow, it’s really cool an electric bike actually, look like it seems to be fun” while I’m just trying to return to my job.

In short, VAE complying with European regulations are practical in some situations, but in others, they are really limited. If you find yourself in a situation where a VAE is simply not fast enough or powerful enough for your needs, then you probably wonder if there is a solution.

The answer is yes, and there are even several. In the rest of this article, I will introduce you to the main ones and explain how to increase the speed of your electric bike. But before that, I just want to warn that the methods presented below are not necessarily legal depending on the country in which you are.

Any changes made to your bike are at your own risk, and you should always be careful to respect the laws of the country in which you live.

Well, now that the warning is out of the way, let me show you the different ways to go faster by electric bike.

1 – Unclog your electric bike

Many European electric bikes have an engine capable of reaching a speed of over 25 km/h.

However, as manufacturers want to comply with European regulations to better sell their products, engines are often programmed to cut from 25 km/h. It’s called: bridging an electric bike motor.

On many engine models, it is possible to cancel this programmed speed limit. And so to unleash his electric bike.

If this solution interests you, you can take a look at the article I wrote on the subject.

2 – Buy an electric bike out of Europe

Surprise surprise, Europe is not the only continent in the world, and it is easy enough to buy products (even as heavy as bicycles) from our neighbors in the East.

Indeed, if there is a country in which the rise in popularity of e-bikes leads to competition, it is in China.

Thus, dozens of companies have created and are currently competing to gain maximum market share. Among these companies, the most popular so far are Addmotor and Crusher.

I know what you are saying without a doubt: “Maaah Robin, it’s the Chinese way, we want solid!”

The thing is that China is currently the world leader in electric bike construction, and by far. Bicycles of brands like Addmotor and Crusher are sold all over the world, and especially in the United States as can be seen on the Amazon USA.

Ah, and in China, there is almost no regulation, so the bikes are not clamped and their power can go up to 750 or even 1000 watts.

A good option to have a fast and unrestricted an electric bike is to buy it online via e-commerce like Aliexpress or Amazon. I also wrote an article that I keep constantly updated in which I group the best electric bikes of the moment.

3 – Make your own electric bike

A third and final option, if you want to have a fast electric bike, is to make it yourself.

Well, this is not about making the best bike us yourself from A to Z, it would be too complicated and especially a great waste of time. In fact, what is called “making your electric bike” is to take a normal bike, and make it electric?

To do this, we add:

  • A motor
  • A battery
  • An accelerator
  • A controller
  • A link between the engine and the wheel

Finding all these elements by yourself and making sure they are all compatible with each other is a beautiful nightmare. Fortunately, there are electric conversion kits with all the necessary equipment and instructions. These kits do not usually include a battery so you can choose the one you want on the side. As for the installation, it takes about 1 to 3 hours depending on whether you are a good handyman or not.

So that you can get a better idea of the installation of one of these kits, here is one of the few videos in French on the subject.

If you already have a bike that you like a lot and you do not want to buy a new one just for it to be electric, installing an electric kit on your current bike is a particularly interesting solution.

In addition, some kits contain very powerful engines that can reach 50 km/h, as for example that of Pasion EBike.

If making your own electric bike is something that interests you, do not hesitate to read the article I wrote on the subject. I explain the different ways to do it by giving the advantages and disadvantages of each.


In conclusion, what should be noted from this article is that in Europe, e-bikes are limited in speed and power as a result of European Union legislation. To comply with these regulations, the manufacturers who market their bikes in Europe are putting a place so called a motor clamp that forces it to cut from 25 km/h.

If you want to have an electric bike faster than that, three options are available to you: unclog your electric bike, buy an electric bike out of Europe, or install an electric kit on a normal bike.
