Last Updated on September 19, 2025 by foysal islam

As the popularity of electric bikes (e-bikes) continues to soar, it’s important for riders to understand the legal limits on their speed. After all, zipping around on a high-powered e-bike can be exhilarating, but it’s crucial to stay within the law for your own safety and that of others. So, how fast are electric bikes allowed to go legally? Let’s dive in and find out.

Understanding E-Bike Classifications

Before we get into the nitty-gritty of speed limits, it’s helpful to know that there are different classes of e-bikes, each with its own set of regulations. In the United States, e-bikes are generally divided into three main categories:

• Class 1 e-bikes: These are pedal-assist bikes that provide electric motor support up to 20 mph.
• Class 2 e-bikes: These are throttle-assisted bikes that can reach speeds up to 20 mph without pedaling.
• Class 3 e-bikes: These are pedal-assist bikes that can provide electric motor support up to 28 mph.

It’s important to note that these classifications can vary slightly between different states and even municipalities, so it’s always a good idea to check your local laws and regulations.

Legal Speed Limits for E-Bikes

Now, let’s dive into the specifics of how fast electric bikes are allowed to go legally. The short answer is: it depends on the class of your e-bike and where you’re riding.

Class 1 and Class 2 E-Bikes

For Class 1 and Class 2 e-bikes, the legal speed limit is generally 20 mph. This means that the electric motor on your bike can only provide assistance up to that speed. Once you exceed 20 mph, the motor will no longer provide any additional power, and you’ll be relying solely on your own pedaling to go faster.

It’s worth noting that some states may have slightly different speed limits for Class 1 and Class 2 e-bikes. For example, in California, the limit is 20 mph on roads, but 15 mph on bike paths and trails. So, it’s always a good idea to check your local regulations.

Class 3 E-Bikes

Class 3 e-bikes, which are the fastest of the bunch, are typically allowed to reach speeds up to 28 mph with electric motor assistance. However, this higher speed limit often comes with additional restrictions, such as requiring the rider to wear a helmet or limiting where they can ride.

For instance, in many states, Class 3 e-bikes are only allowed on roads, and not on bike paths or trails. This is to ensure the safety of other cyclists and pedestrians who may not be expecting a bike to be traveling at such high speeds.

Factors That Can Affect E-Bike Speed Limits

While the general speed limits for e-bikes are as outlined above, there are a few other factors that can influence how fast you’re legally allowed to go:

• Rider Age: Some states have age restrictions on certain e-bike classes, which can impact the speed limit. For example, in California, riders under 16 are only allowed to operate Class 1 or Class 2 e-bikes.
• Location: As mentioned earlier, speed limits can vary depending on whether you’re riding on the road, a bike path, or a trail. It’s essential to be aware of the local regulations in the areas you’re riding.
• Battery Power: The maximum speed of an e-bike is often limited by the power of the bike’s battery. Higher-powered batteries can propel the bike to faster speeds, but that may push it beyond the legal limits.

Conclusion

In summary, the legal speed limits for electric bikes in the United States are generally as follows:

• Class 1 and Class 2 e-bikes: 20 mph
• Class 3 e-bikes: 28 mph

However, it’s crucial to always check your local laws and regulations, as speed limits and other restrictions can vary depending on your location, the type of e-bike you’re riding, and even your age. By understanding and adhering to the legal speed limits, you can enjoy the thrill of riding an electric bike while prioritizing your safety and that of others on the road or trail.
