How Fast Does An Electric Bike Go

How Fast Does An Electric Bike Go 800

Electric bikes are tiny cruisers. As you plan your tour, check your routes so that they are friendly enough to favor your bike’s top speed. But riders sometimes never explore the full speed due to fear or state regulations. If you didn’t know, some electric bikes can match your old car’s(at the garage) top speed of 45 kilometers per hour!

As long as you’re pedaling, you can go as fast as you can pedal. Unfortunately, e-bikes stop electric assistance when you exceed 20mph. Some e-bikes (Class 3 e-bikes) help you accelerate to top speeds of about 28mph. 

That’s not all. Certain bikes record top speeds of 80 – 100km/h. You can check out more information on Amazon here. Electric bikes are buzzing and booming, imagine acquiring an HPC Revolution, a flagship model that can clock top speeds of 60MPH.

These are not just bikes, but real hits because not all e-bikes can reach such speeds. In this article, we’ll describe the key qualities and factors that determine the speed of electric bikes.

How Fast Can An E-Bike Go

An e-bike is faster than a manual bike due to the motor. E-bikes’ speed is regulated, and the speed is classified into three levels (see below). In Europe, e-bikes have a peak power of 250 watts and speed at not more than 15.5mph, while in the US, e-bikes can use a 750-watt motor and reach top speeds of about 20mph.

Some speeds can only be attained with the help of manual pedaling, although expensive models like Scrambler do not require it.

E-bike classification

E-bike is classified into 3 categories according to their speeds. 

Class 1Class 2Class 3
ThrottleNot assistedAvailableNot assisted
Maximum speed20mph20mph28mph

Class 1

Pedaling is assisted while the throttle isn’t. You can ride them on bike paths up to a speed of 20mph. If you love biking for fun, this is the best choice for you, because enjoying a leisurely ride doesn’t demand high speeds. Such bikes are fitted with a Bosch Performance Line (20mph)

Class 2

Both pedaling and throttle are assisted, though low key. You can enjoy sailing without pedaling support although the speed limit is still 20mph. The bike may still exceed this speed with some pedaling but it is prohibited in all of the US states.

Some popular models are QuietKat, Ride1UP, and Lectric.

You have to manually determine your bike speed here, whether to exceed the recommended speed or not.

Class 3

These are speed pedal-assisted electric bikes known for the ultimate comfort they provide when a rider is pedaling. They lack a throttle, but when a rider enforces it, the top speed (28mph) is reduced to 20mph and accelerates back to the top speed if pedaling resumes.

Class 3 e-bikes are faster and more enjoyable to those who like setting challenges like achieving new targets or working with a specific time. Again, the cruise speed depends entirely on you. If you want to go slower, turn on the throttle, and off to pedal to level up to your desired speed

Factors Affecting E-bikes Speed

Some bikes cruise faster than others, because of the power factor as seen above, but other factors influence speeds directly.

Motor strength

The higher the wattage, the higher the power, and the faster the bike. If you pedal your bike as you rely on the motor, your weight will determine the speed your e-bike can attain.

A 100-pound biker pedaling uphill assisted by a 250-watt e-bike will not require much power compared to a 150-pound biker relying on the same bike ascending the same terrain. The two speeds will vary with the heavier biker gliding slower.

Similarly, if riding on a stronger motor, the speed is swift due to the strong power produced.


Although not all bikes require pedaling when the motor is running, pedaling can help you reach the top speeds easily and faster. This depends on whichever e-bike class you own. Class 1 e-bikes have less powerful motors, so you’re required to pedal for assistance when the motor is running. That suits you especially if you’re a ‘workout’ type of a biker.

Know the role of your e-bike. If your bike is a ‘job commuter’, then consider Class 2 and Class 3. They can move faster and without pedaling.


Steeper terrains require a lot of power. Hence, consider getting an e-bike powered by a 750-watt motor. 

State laws and Leisure

Different e-bikes have different limits and purposes. If you exceed 150 pounds, use a 500w to a 750w e-bike. Check your local state laws to see the required speed limits of an electric bike.

Mostly, States have e-bike speed limits of 20mph. Unless you’d like to retrofit your e-bike, most models are limited to a 750-watt motor.

How fast can a 250-watt electric bike go? At approximately 20mph assuming you weigh anywhere between 100 to 140 pounds.

So, next time you ride, offer your bike full credit by trying out how fast you can sail! Make sure you wear a helmet and the right outfit.
