Electric bikes are great tools for commuting, especially those capable of reaching high speeds. But not all e-bikes have identical top speeds.
Generally, the speed of an electric bike depends on its motor Watt rating. So, for example, e-bikes with a high Watt rating reach the highest speeds.
This article will explore how fast electric bikes go, including their average speeds.
Most electric bikes can reach speeds between 15mph (24kph) and 20mph (32kph). The average top speed for e-bikes is about 28mph (45kph).
Still, the speed range of an e-bike varies depending on its Watt rating. So, let’s examine the average speed of electric bikes based on their wattage.
A 750W electric bike can reach a top speed of about 28mph (45kph).
This means that e-bikes with 750W motors feature an average top speed.
A 1000W e-bike can reach a top speed of about 35mph (56kph). Many adult-sized commuter e-bikes fall into this category.
A 2000W electric bike can reach a top speed of about 43mph (69kph). Still, this top speed is only possible on flat surfaces.
Riders who use a 2000W e-bike on inclines will likely experience lower top speeds.
Theoretically, a 3000W e-bike can reach 50mph (80kph) or more. Still, most electric bicycles with 3000W motors have lower top speeds.
E-bike manufacturers tend to limit top speeds to 40mph (64kph) or lower for safety reasons.
An e-bike with a 5000W motor can potentially reach 65mph (105kph). But most manufacturers limit top speeds to 40mph (64kph).
Unlike motorcycles, bicycles aren’t typically built to withstand speeds greater than 40mph. Consequently, top speed limitations keep riders safer and prevent serious mechanical problems.
|Electric Bike||Top Speed|
|750 W||28mph (45kph)|
|1000 W||35mph (56kph)|
|2000 W||40mph (64kph)|
|3000 W||40mph (64kph)|
|5000 W||40mph (64kph)|
The slowest e-bikes are often designed for children. These bikes might have a top speed of about 9mph (approximately 15kph).
The lowest speed setting is typically between 3mph (5kph) and 5mph (8kph). The STAYC 12eDRIVE is an excellent example of a low-speed e-bike.
Adult e-bikes often feature much faster speeds.
For example, the Rad Power Bikes RadMission e-bike has a top speed of 20mph (32kph). Without the pedal assist function, it travels as fast as the rider can pedal.
Consequently, the lowest speed of an e-bike varies between about 3mph (5kph) to 20mph (32kph).
The fastest electric bicycle is the Delfast Top 3.0. It has a top speed of 50mph (80kph).
Somewhat surprisingly, this bicycle has a 3000W motor, which is less powerful than other e-bikes. But when users operate it at full speed, its battery life suffers.
It’s crucial to remember that e-bikes with higher speeds may have shorter battery lives. After all, bicycles only have so much room for a battery.
As a result, e-bike batteries can only carry a specific amount of charge. When used at higher speeds, these batteries can drain quickly.
Several factors influence an e-bike’s top speed. Some of the most significant factors include:
- Bike and rider weight
- Bike motor Watt rating
- Pathway elevation
Let’s explore these factors to discover how they impact an e-bike’s speed.
A bike’s initial weight can impact its maximum speed. Moving heavier bikes requires greater amounts of energy.
But an e-bike’s battery has a limited power capacity. Equally, its motor can only generate so much force.
As a result, lightweight e-bikes can sometimes reach higher speeds. Lighter riders may also experience faster top speeds.
However, weight isn’t as crucial as an electric bike’s motor wattage.
An electric bike’s Watt rating refers to the amount of power the motor can consume. Motors with higher Watt ratings tend to be powerful.
As you might expect, powerful motors are more capable of reaching incredible top speeds.
The elevation of your chosen route also impacts speed.
When bikes climb hills, their top speed decreases. But the opposite is true when traveling down an incline.
An e-bike’s motor has to work harder to scale inclines. So it’s unable to produce the same speeds available on flat surfaces.
A fast e-bike might seem like a natural choice for commuters. But it’s important to note that speed impacts battery life.
The faster you choose to operate an electric bicycle, the more you drain battery power. So, if you consistently ride at an e-bike’s top speed, battery life may be short.
Are you looking to balance speed and battery life? If so, you’ll want to choose an e-bike with a high battery capacity.
The battery capacity of an e-bike typically varies between 24V and 48V. Those looking to travel several miles at top speed should choose a 48V e-bike.
These high-capacity electric bicycles can also handle elevations more easily. After all, they’ll have more battery power to push you up hills.
Electric bikes and standing commuter scooters are equally fast. Both have a maximum top speed of 50mph (80kph).
That said, standing commuter scooters have a lower average speed. Adult-sized electric scooters have an average speed of about 15mph (24kph).
Gasoline-powered scooters often have much higher average speeds. However, you may need a special license to operate these vehicles.

You may be required by law to operate an e-bike on roadways. After all, some electric bicycles can reach incredible top speeds.
Operating these bikes on sidewalks could pose a danger to pedestrians. However, riding an e-bike on a roadway can be dangerous.
Be sure to consult with your local Department of Transportation (DoT) before operating an e-bike. They should be able to offer guidance about whether to ride on roads or sidewalks.
If you’re riding an electric bicycle in the U.S., you’ll need a helmet. After all, e-bikes can reach impressive speeds.
If you’re traveling at 20mph and suddenly fall, you could suffer severe injuries. Wearing a helmet protects your skull, potentially preventing fatal accidents.
Besides, many states require bicyclists to wear helmets, no matter their age. Refusing to wear a helmet while operating an e-bike can result in hefty fines.
Riders using high-speed e-bikes may also want to wear wrist and knee protectors. Other safety gear, including high-visibility clothing, is also recommended.
The average speed of an electric bike is 20mph (32kph). However, a bike’s speed range depends on its Watt rating.
The slowest e-bikes are those with a 750W rating. These can reach speeds of 28mph (45kph).
The fastest e-bikes are those with a 5000W (or higher) rating. These can reach speeds of 65mph (105kph) or higher.
However, most e-bike manufacturers limit bike speed to 40mph (64kph) or less. This design feature helps keep riders safe.
When operating a high-speed electric bike, be sure to exercise caution. You’ll also want to wear a helmet, especially if riding in the U.S.
