Why Are Electric Bikes So Slow In Speed Up To 25 km/hr

Why Are Electric Bikes So Slow In Speed Up To 25 km/hr?

Electric bikes have become the next best thing after motorcycles in modern transportation. When it comes to speed, they surpass the standard bicycle. Yet, at 25 km/h, they are slower than a decent motorcycle. But why are electric bikes so slow, even at speeds of up to 25 kilometres per hour?

Electric bikes are not slow; 25 km/hr is the legal limit in most states. Most electric bicycles can reach speeds above 80 kilometres per hour. Excellent for those seeking to protect the environment.

But you’ll find each region, country, or state has its own rules and regulations. The rules and regulations help riders use electric bikes on public roads. We’ll look at different speed limits around the world in this article.

What Is The Speed Limit In Different  Countries?

The motor’s gearing and power output will decide the best speed for an electric bike. The power output of a pedal-assist electric bike is around 200 watts, giving it a top speed of 28 miles per hour( 45.06km/hr). As the battery discharges, the speed will decrease.

But, it is crucial to be aware of all laws and regulations. Ensure to follow all the rules and regulations to avoid accidents. You might attract heavy penalties if you don’t.

Consider the legal speed limits in different places of the world.

Speed Limit In Different Countries

🇺🇸The United States

Under motor power alone, the legal speed limit for electric bikes in the United States is 20 miles per hour (32km/hr). Most states’ three-tiered classification system appears to support this rule. Class 1 and 2 electric bikes limit are 20 miles per hour. For class 3 electric bikes, the limit is 28 miles per hour.

Let’s have a look at these three-tiered classifications.

  • Class 1:This class includes an electric bike with the greatest speed of 32km/hr. And an electric motor that only functions when the rider pedals (pedal-assist).
  • Class 2: This is the category for electric bikes with throttle-controlled motors. When the bike achieves a speed of 32km per hour, the motor must turn off.
  • Class 3: The bicycle has a motor that only assists when the rider is pedaling. The motor should stop assisting when the electric bike reaches a speed of 45 km per hour. This class is the most restricted, and some states have imposed extra safety rules.

Some states have separate speed restrictions for electric bikes. You should stick to the local speed limits when on the road.

🇪🇺Europe And 🇬🇧The United Kingdom

An electric bike in the EU and the UK has a motor with a continuous rated power output of less than 250W. The greatest assisted speed is 25 kilometers per hour. The rider can go faster than this, but electrical help is not permitted after 25 km/hr.

Electric bikes with greater output than 250W at full throttle have different laws.  They can travel at the best speed of 45 kilometers per hour. But you need to register them as motor vehicles for public roads.


In Australia, an electric bike is a bicycle with an extra motor. The motor output should not exceed 250 W. 

The regulations in Australia are different from those in the United States. The classifications in Australia are also different. Australia has based its bike rule on those in Europe. 

Their classifications and guidelines are as follows:

  • Pedal-assist: Pedaling is the only way to engage the electric motor system here. These electric bikes must be EN15194-certified and have a preferable wattage of 250 W and 25 km/h speed.
  • Throttle on-demand: You can use a trigger, grip twist or button to activate electric bikes. You can propel some electric bikes using a throttle alone. But others still need pedaling.

In Australia, an electric bicycle with a throttle must pedal. Throttle electric bikes should have a motor wattage of 200w and a top speed of 25km/hr.


The federal law in Canada describes electric bikes as power-assisted bicycles. The allowed power output of electric bikes in Canada is 500W. The official legal speed limit is 32km/h(20mph). Anything higher than that is illegal, but each state can change.

Only ten provinces in Canada currently allow electric bikes. If you live in one of these provinces, you should familiarize yourself with the local rules.  These are the states that have established electric bike regulations.

  • Ontario, 
  • Nova Scotia, 
  • Prince Edward Island, 
  • Quebec, 
  • Alberta, 
  • Newfoundland and Labrador, 
  • British Columbia, 
  • Manitoba, 
  • Saskatchewan, and 
  • New Brunswick 


Most people in China prefer the electric bike. The bike can maneuver through congested urban areas. As a result, the state passed some laws for electric bike riders to observe.

The allowed power output for the electric bike should be 400W. You should not exceed a speed limit of 25km/hr. But you might find different rules in the provinces which you should follow.


In Japan, the allowed speed for an electric bike is 24 km/hr. After which, you must turn off the electric assist. You can only go faster than the speed limit if you keep pedaling without using the motor.

In Japan, the allowed motor output is 250 watts. You can only ride an electric bike with pedal assist. You must register as a 55 cc or smaller engine size to use the throttle-based electric bike. A number plate and a driver’s license will be necessary as well.


Electric bikes in India must have a power output of less than 250W. In India, the allowed speed for riding an electric bike on public highways is 25 kilometers per hour. You will not need a road license if you follow these two rules.

You’ll need a road license for electric motorcycles with more than 250 W power output. But most electric bikes in India are under 250W and have a legal 25km/hr speed.

🇳🇿New Zealand

In New Zealand, an electric bike has an extra electric motor. The motor should not exceed 300 W. It should use the rider’s energy to power it. The state allows a speed of 25km/hr for new riders and 32km/hr for more experienced.

If you need to go faster than this, you’ll have to power your energy. The New Zealand Transport Agency has some advice for you when choosing an electric bike. Choose one with a motor in the rear of the middle. Unlike the one with a motor in the front, you can manage the former like a standard bike.


In Israel, the state has allowed a speed limit of 25km/hr for electric bikes. The electric motor power should not exceed an output of 250W. 

You must be above 16 years of age and have a driver’s license or a special license. You’ll get the license after you have attended a special course taught in school. You can also attend various centers around Israel.


Electric bikes are becoming more popular. They lack noise, pollution, and vibrations. Unlike a standard bike, you can travel long distances.

Most states have established rules and regulations. The rules help the riders to know what is good on public roads. Observing such laws and regulations would be prudent to avoid getting into trouble.
