Electric bikes can go surprisingly fast, but only up to a certain limit. As speed increases, the question also arises as to what the law actually allows and at what point an electric bike ceases to be an ordinary bicycle.

The speed limit for electric bikes directly affects whether insurance or registration is required. This article clearly explains what the law says about the maximum speed of electric bikes, why 25 km/h is a key limit, and what can happen if it is exceeded.

Electric Bike Speed Limit: 25 km/h is the EU Standard

In Finland and practically all EU countries, electric bike assistance is designed to stop when the bike's speed reaches 25 km/h. This is not a manufacturer-specific recommendation, but a limit based on EU legislation that defines when an electrically assisted bicycle is classified as a regular bicycle.

According to EU legislation, electric motor assistance must cease at the latest when the bike's speed reaches 25 km/h. After this, the bike can still go faster, but the speed comes from the rider's own pedaling or, for example, downhill, meaning the motor no longer assists.

In addition to the speed limit, the law also sets requirements for motor power. An electrically assisted bicycle is classified as a bicycle when the continuous rated power of the motor is a maximum of 250 watts and the motor assistance ceases at a speed of 25 km/h at the latest. If these conditions are met, the bike can be ridden without registration or motor insurance in the same way as a regular bicycle.

It is important to remember that 25 km/h refers specifically to motor assistance, not the actual maximum speed of the bike. Downhill or with strong pedaling, an electric bike can go well over 25 km/h, and the law does not prohibit this, as long as the additional speed does not come from electric motor assistance.

What if you want a faster bike?

If the 25 km/h assistance of a standard electric bike feels too slow, an alternative is the so-called speed pedelec. In these bikes, the motor assists pedaling up to 45 km/h, and they are intended for significantly faster travel than ordinary electrically assisted bikes.

Faster electric bikes do not fall under the definition of an electrically assisted bicycle; instead, they are classified as motor vehicles in Finland based on their technical characteristics.

In practice, such bikes usually fall into the category of mopeds (for example, class L1e-B), and their use in road traffic requires registration and motor insurance, as well as a driving license for the rider.

Before purchasing, it is good to ensure that you understand what the classification means in practice: a faster electric bike brings more speed, but also more obligations than a regular electric bike that travels at a maximum of 25 km/h.

What happens if the electric bike speed limit is exceeded?

Many cyclists are tempted to tune their bikes so that motor assistance continues beyond 25 km/h. However, this is problematic for several reasons.

If an electric bike is modified in such a way that it no longer meets the legal definition of an electrically assisted bicycle, it can no longer be used in traffic as a regular bicycle. As a result of the modification, the vehicle may fall into another vehicle category, creating, for example, registration, insurance, and other statutory requirements.

Tuning can also have significant financial consequences in the event of an accident. If an electric bike has been modified in such a way that it no longer meets the legal requirements, this can affect the insurability of claims.

In addition, the lack of motor insurance in a situation where it would have been mandatory can lead to significant financial liability.

Electric bike law and insurance – when is motor insurance needed?

According to the Finnish Motor Insurers’ Centre, the vast majority of electric bikes sold in Finland are electrically assisted bicycles that do not require motor insurance.

The amendment to the Motor Liability Insurance Act that came into force in 2024 brought primarily electric mobility devices into the scope of mandatory insurance that do not meet the definition of a standard electrically assisted bicycle or whose characteristics exceed the limits set by law.

When motor insurance is not needed:

• When it is an electrically assisted bicycle whose motor only operates when pedaling, the continuous rated power of the motor is a maximum of 250 watts, and assistance ceases at a speed of 25 km/h at the latest, motor insurance is not required. The weight of the bike is irrelevant in this case.
• The Motor Liability Insurance Act also has its own regulations for electrically assisted bicycles with a maximum of 1000 watts. For such bikes, motor insurance is only required if their unladen mass exceeds 25 kilograms.

It is important to note, however, that this latter regulation concerns motor insurance obligation, and it does not mean that all electric bikes up to 1000 watts are ordinary electrically assisted bicycles in road traffic legislation. The classification of a vehicle is also affected by other technical characteristics and the vehicle legislation applicable to it.

A particularly important point concerns self-imposed speed limits. Installing a limiter afterwards does not change the bike's official classification. In the Motor Liability Insurance Act, structural speed refers to the structural speed determined by the manufacturer or importer, and changes made by the user themselves do not alter the vehicle's original classification.

For example, a bike designed for a speed of 45 km/h does not become a regular electrically assisted bicycle merely by having its assistance limited to 25 km/h afterwards.

This is one of the most common misconceptions regarding electric bikes. What is decisive is not how fast the bike is actually ridden, but how the vehicle has been approved and classified by the manufacturer.

So, how fast can an electric bike go?

In summary, the continuous rated power of an electrically assisted bicycle's motor may not exceed 250 watts, and the motor's assistance must cease at a speed of 25 km/h at the latest. When these conditions are met, the vehicle is equated to a regular bicycle, and generally no registration or motor insurance is required for it.

Faster electric bikes, for example, those assisting up to 45 km/h, may only be used in road traffic if they meet the requirements of the vehicle legislation applicable to them.

If you are planning to purchase an electric bike or want to verify the legality of your current bike, check the technical specifications provided by the manufacturer – especially the continuous rated power of the motor and the speed at which assistance cuts off.

If necessary, you can also use the Finnish Motor Insurers’ Centre's online test to find out if your bike requires motor insurance. This ensures that riding an electric bike is both safe and legal.
