How Fast Does a 500W Electric Bike GO?

How Fast Does a 500W Electric Bike Go?

Electric bikes are becoming more popular every day, and many people are curious about their speed and performance. If you are considering buying a 500W e-bike, you are probably wondering how fast does a 500W electric bike go? The answer is: it depends. 

There are a number of factors that can affect the top speed of an electric bike. They include the weight of the rider and cargo, the terrain, the level of pedal assistance, and the wind conditions.

In this article, we will explain what factors affect the speed of an electric bike, and how you can estimate the maximum speed of a 500W electric bike. We will also explain how far a 500W e-bike can go, and how to ride safely and legally on an electric bike. 

By the end of this article, you will have a better understanding of how fast a 500W electric bike can go, and how to enjoy it responsibly.

What is Wattage in an Electric Bike?

Let’s dive into some physics today! The wattage of an e-bike is simply the total power output of its motor. To calculate wattage, we use a simple mathematical formula:

Wattage = Voltage x Amp-hours

          W = V x Ah

Here, “Voltage” refers to the electrical force measured in volts, and “Ampere-hours” of the controller refers to the maximum current flowing from the bike’s battery to the motor. 

To better understand this formula, let’s take an example. If your e-bike has a 36 volts, 14 amp-hours controller, then its motor output will be 36 x 14 = 504 watts.

It is important to note that wattage refers to the power output of your electric bike’s motor, while watt-hours of the battery indicate the power supplied by the battery to the motor every hour .

Who Should Ride a 500W Electric Bike?

If you are looking for an e-bike that offers the perfect balance between speed and control, then a 500W electric bike is what you need. It is ideal for those who want to go a little faster than a 250W model without sacrificing stability like a 750W electric bike.

A 500 watts e-bike is enough for you to commute on country roads or tackle slightly steep hills. For mountain biking enthusiasts, we recommend opting for a mid-drive motor instead of a hub motor. A mid-drive motor provides better performance and control, especially on challenging terrains.

In the USA market, you will find a wide variety of e-bikes designed to cover long distances and offer impressive acceleration. However, 500W electric bikes are not legal in the UK and EU due to regulatory restrictions.

How Fast Does a 500W Electric Bike Go on Various Surfaces?

A 500-watt electric bike is capable of reaching speeds of around 20 mph on paved roads and up to 25 mph when riding downhill. However, these speeds may vary depending on factors such as terrain, battery voltage, rider’s weight, and motor type.

Here’s a breakdown of the top speeds you can expect from a 500W e-bike on different surfaces:

  • Paved or Flat Roads: Up to 20 mph (32 km/h)
  • Uphill or Inclined: Up to 12 mph (20 km/h)
  • Downhill or Declined: Up to 25 mph (40 km/h)

Before you hit the road, it’s important to familiarize yourself with the local laws and regulations. Safety should always be a priority for both yourself and others sharing the road.

In the United States, electric bikes are classified into three categories based on speed: 

  • Class 1
  • Class 2
  • Class 3 

Class 1 and Class 2 electric bikes have a maximum speed limit of 20 mph and a maximum motor wattage of up to 750 watts.

On the other hand, Class 3 electric bikes can reach speeds of up to 28 mph without using throttle mode. The motor assistance stops once you reach this speed, but you can still increase your speed by pedaling.

According to U.S. law, a 500 watts electric bike has a maximum speed of 20 miles per hour when using throttle mode on flat roads. However, you can achieve speeds of up to 25 mph or more by pedaling.

Keep in mind that removing the speed limiter on your e-bike is considered a violation of the law and can result in heavy fines and penalties. Always adhere to the legal requirements and prioritize safety.

Furthermore, any bike with a motor exceeding 750 watts would no longer be classified as an electric bike. Instead, it would be considered a motorbike and subject to registration, insurance, and other legal requirements.

How Far Can a 500W Electric Bike Go?

You might think that a bigger battery means a longer ride, but that’s not always the case. A bigger battery also has to feed a bigger motor, and that can drain your power quickly. The range of a 500w electric bike also depends on other factors, such as the level of pedal assist, the terrain, the rider’s weight, and the speed.

Many 500W electric bikes have the same riding range as a 250W electric bike, which is about 25 to 50 miles per charge. That’s not bad, but it’s not impressive either. If you want to go further on a single charge, you need to look at more than just the battery size.

A 500w electric bike can also reach a top speed of about 20 to 25 mph, depending on the regulations in your country. 

500W Electric Bike Top Speed According to Types of Motors

The two main types of motors you will find in e-bikes are: direct hub motors and mid-drive motors.

A hub motor system is simple, cost-effective, and provides sufficient pedal-assist power for commuting at speeds of up to 20 mph. It offers assistance based on the cadence sensor, which means you will receive support even if you are not pedaling vigorously.

On the other hand, a mid-drive motor is compact, powerful, and more energy-efficient. Its weight is evenly distributed, which makes handling easier and provides greater speed and torque compared to a hub motor (up to 25 mph).

If you are into mountain biking or work as a delivery person, an electric bike equipped with a 500W mid-drive motor will deliver excellent torque on all terrains.

For riders who primarily stick to ground-level roads with occasional terrains here and there, the rear hub motor is a suitable choice. While a mid-drive motor offers superior performance, it comes at a higher cost compared to a hub motor.

If you are planning to convert your regular bike into an electric one, a direct hub motor will be a good option. Mid-drive motors require a special frame design for installation.

On the other hand, a direct electric bike hub motor system can be easily installed at a low cost with any frame design. These motors are installed in the wheels, making removal and maintenance much easier.

Keep in mind that both hub and mid-drive motors may present some challenges along the way. However, with proper maintenance and care, you can enjoy the benefits of your e-bike for years to come.

Factors Affecting the Speed of a 500W E-Bike

Following are the factors that may affect the speed of your 500W electric bike:

Weight of the Rider

If you are carrying some extra weight, it’s important to consider how it affects your e-bike’s performance. A heavier load can put additional strain on the bike and reduce the speed of your 500W electric bike. Weight distribution and overall balance play a crucial role in optimizing your riding experience.

Battery Capacity

If the capacity of your e-bike battery is less than 500 watts, then your electric bike will not reach its maximum speed. This is because the battery is not capable enough to provide the required power. 

Types of Surface

A 500 watts electric bike runs faster on flat and downhill roads compared to uphill and rough roads.

Weight of the Battery

Using a heavy battery reduces the speed of the e-bike. If you don’t need a higher range, it’s better to avoid using a heavy battery because it will slow you down.

Bike Frame Density

The bike’s speed decreases when the frame is heavy because it adds more weight for the motor to carry.

Pedal Assistance Level

A higher level of pedal assistance gives more speed than a lower level, but it also drains the battery faster.

Frequent Braking

Using brakes often on an electric bike slows down the motor. This means you will need to re-accelerate to make the speed up again. It will use more battery power and lower your range.

Opposition by the Wind

Wind resistance slows you down when you ride against it. How much it will affect your e-bike speed depends on the terrain.

Weight of Grocery/Backpack

Heavy loads slow down your e-bike because they make the motor work harder, and that reduces your speed. It is simple physics, but it can make a big difference in your riding experience.

Kind of Motor and Sensors Used

A mid-drive motor has a torque sensor that adjusts to your pedaling force and balances the weight of the bike in the center. This gives you more speed and efficiency. 

On the other hand, a hub motor has a cadence sensor that only detects your pedaling speed and puts the weight of the bike on the rear wheel. This makes you slower and less stable. 

Is 500 Watts Enough for an Electric bike?

It depends on what you want to do with it. There’s no right or wrong answer, but there are some questions you can ask yourself to find the best fit for your needs. Here they are:

  • How often will you ride your electric bike?
  • Will you use it as your main transportation? 
  • Will you use it just for fun?
  • Will you ride mostly on flat roads or hills?
  • How much weight will you carry on your e-bike (including yourself and your cargo)?
  • How much do you weigh (your weight will put extra pressure on the motor)?

These questions will help you decide if a 500 watts e-bike is enough for you or if you need more power. For example, if you ride mostly on hills, you might want a higher-wattage electric bike (like 750 watts) or a 500 watts mid-drive motor that can handle the incline better. 

But if you ride on flat roads for leisure or commuting, a 500 watts electric bike can do the job well, even with some extra weight. And if you are looking for a thrill on the trails, you might want to go for a 2000 watts electric bike that can reach high speeds and handle rough terrain.

Is 20 Miles Per Hour Fast Enough For an Electric Bike?

You might think a 250 watts electric bike is slow, but it’s actually faster than you need. The top speed on flat ground is 20 mph, which is more than enough for most situations. It is also the legal limit for electric bikes in the U.S.

In Europe, where e-bikes are very popular, they can only go up to 15 mph. That’s still faster than the average cyclist on a regular bike, who rarely goes above 12 mph.

And don’t worry, you can still go faster than 20 mph if you want to. Your electric bike won’t stop you from cruising downhill — it just won’t help you with the motor. You will have to rely on gravity and your own pedaling power.

Pros and Cons of a 500 Watts Electric Bike


  • It offers you the maximum speed and power that the law allows with a 20 mph top speed
  • It can accelerate on hills with ease with the right battery size for your bike
  • It is not very heavy
  • It can climb hills effortlessly with a 500 watts mid-drive motor that delivers torque and speed
  • Delivery agents can use it to deliver goods quickly and efficiently
  • It can travel long distances on flat roads 


  • The motor can drain out the battery if you do not pair it with the right size of battery
  • It is more expensive and heavier than a 250W e-bike
  • It struggles on steep slopes that require more power and speed

Can a 500 Watts Electric Bike Go Uphill?

You love the thrill of riding uphill, but you don’t want to break a sweat. You need a 500 watts electric bike that can handle the challenge. A 500W e-bike has enough power to speed up on moderate slopes, as long as they are not too steep.

But there’s more to it than just the motor. The weight of the rider, the wind resistance, and the battery voltage and weight also affect how well a 500-watt bike can climb hills.

So, how do you know if a 500W e-bike is right for you? It depends on your personal preferences and goals. A 500W electric bike can perform well on gentle inclines and average on steep ones, but it won’t be able to conquer the toughest terrains.

If you are looking for a bike that can tackle any hill, you might want to consider a mountain electric bike with a 750W or 1000W mid-drive motor. These bikes are designed for hill climbing, and they can deliver impressive speed and torque on any slope.

Comparing 500-Watt and 1000-Watt Electric Bikes

You might think that a 500W e-bike motor is enough for your needs, but you would be surprised by how much more power you can get from a 1000W e-bike motor. 

In fact, the difference is huge: 500 watts more, to be exact. That’s like adding another half of your motor to your bike. But what does that mean in terms of performance and benefits? 

Let’s take a closer look at the main differences between a 500W vs 1000W electric bike motor:

  • A 1000-watt e-bike gives you a whole new level of power and performance than a 500-watt e-bike. Of course, that comes at a higher cost, but it might be worth it for you.
  • A 500-watt e-bike can handle some gentle slopes, but a 1000-watt e-bike can climb steep hills with ease. You will feel the difference when you pedal up steep inclines with a powerful motor behind you.
  • A 500-watt e-bike is great for cruising around the city, but a 1000-watt e-bike is more like a mountain bike. You can tackle any terrain with confidence and speed with a 1000-watt e-bike.
  • A 500-watt e-bike can reach a top speed of about 25 mph with pedal assist, but a 1000-watt e-bike can go even faster. You can reach up to 40 mph with a 1000-watt e-bike, which is as fast as a car.
  • A 500-watt e-bike is lighter than a 1000-watt e-bike, because it has a smaller battery and motor. That makes it easier to carry and store. A 1000-watt e-bike is heavier, but it also has more range and power.
  • The choice between a 500-watt and a 1000-watt e-bike depends on what you value most: price, speed, range, or hill performance. You have to weigh the pros and cons of each option and decide what suits your needs best.

Classes of E-Bikes: Which One Should You Opt for Your 500W E-Bike?

Not all e-bikes are created equal. Depending on how fast you want to go and how much power you need, you may have to choose between different classes of e-bikes in the USA. Here’s what you need to know about the three classes of electric bikes and how they relate to your 500W motor.

Class 1 Electric Bikes (Pedal-Assist Only, Up to 20 mph)

If you want an e-bike that feels like a regular bike, but with some extra boost, you should go for a class 1 e-bike. These e-bikes only provide assistance when you pedal, and they stop assisting when you reach 20 mph. 

They are suitable for most bike paths and trails, and they don’t require a license or registration. The motor’s wattage can range from 250 watts to 750 watts, so a 500-watt motor would fit in this category.

Class 2 Electric Bikes (Throttle-Assist, Up to 20 mph) 

If you want an e-bike that can propel you without pedaling, you should go for a class 2 e-bike. These e-bikes have a throttle mode that allows you to control the speed with a twist or a button. They also stop assisting when you reach 20 mph, but they can be faster than class 1 e-bikes if you pedal along with the throttle. 

They are allowed on most bike lanes and roads, but they may be restricted on some bike paths and trails. The motor’s wattage can also range from 250 watts to 750 watts, so a 500-watt motor would also fit in this category.

Class 3 Electric Bikes (Pedal-Assist Only, Up to 28 mph) 

If you want an e-bike that can go faster than 20 mph, you should go for a class 3 e-bike. These e-bikes only provide assistance when you pedal, but they can assist up to 28 mph. They are ideal for commuters and enthusiasts who want more speed and challenge. 

They are not allowed on most bike paths and trails, and they may require a license, registration, and helmet in some states. They also have a screen that displays the speed and distance. The motor’s wattage can be higher than 750 watts, but a 500-watt motor would still work in this category.

So, which class of e-bike should you choose for your 500-watt motor? It depends on your personal preference and the laws in your area. Whatever you choose, make sure you ride safely and responsibly, and enjoy the benefits of e-biking!


How fast can you go on a 500W electric bike? The answer is 20 to 25 mph, but that’s not the whole story. It also depends on the motor and other factors. But is that fast enough for you?

A 500W electric bike is a great choice for cruising around the city or enjoying some leisure time. It has enough power to handle flat roads and moderate hills, and it’s safe and comfortable to ride. Plus, it’s legal in most states, unlike some of the more powerful e-bikes that can go over 20 mph with pedal assist.

If you are looking for an electric bike that can handle off-road adventures, you might want to consider a higher wattage model. A 750W e-bike or higher can give you more speed and torque, which can make a big difference on rough terrains. 

Just be aware that these electric bikes are not allowed on public roads in many states, so you will need to find a suitable place to ride them.

Before you buy an e-bike, think about what you want to use it for, how fast you want to go, and what kind of rider you are. There’s no one-size-fits-all solution, but there’s an electric bike for everyone. You just need to find the one that suits you best.
