How to Remove the Speed Limit on an Electric Bike
Speed limit is a feature built into electric bikes that is designed to limit the maximum speed of the electric bike.Typically, the controller on an electric bike is equipped with a speed limiter, which limits the motor power to ensure that the speed of the electric bike is controlled within the allowed range. In the United States, the speed of electric bikes is usually controlled at 20-28mph.
Why Do Electric Bikes Need Speed Limiters?
Almost every electric bike is equipped with a speed limiter to ensure the safety of the rider and comply with local laws. The functions of the speed limiter usually include:
Improve safety: Like motorcycles, electric bicycles have an increased chance of traffic accidents when they are too fast. By limiting the maximum speed of electric bicycles, the risk of accidents can be greatly reduced.
Legal compliance: In the United States, the maximum speed limit for electric bicycles in most areas does not exceed 28mph. The speed limiter can ensure that you comply with local traffic laws when riding.
Extended service life: By limiting motor power, you can extend the service life of the battery, motor, and even the tires.
Therefore, the installation of a speed limiter is necessary. It not only protects your riding safety, but also effectively extends the service life of your electric bicycle.
Why Remove Speed Limiters?
We have received some inquiries from customers about how to remove speed restrictions. For some personal reasons, some people may need to remove speed restrictions.
Increased speed: Some riders seek out higher speeds, and by removing the speed limit, e-bikes can reach speeds of 40mph or even 50mph, providing a faster riding experience.
Save time: Due to long-distance commuting or outdoor riding needs, faster speed can save more time.
Bicycle modification: Some riders like to modify their bicycles, and adjusting the speed of the bicycle is one of the very common modification projects.
It is common to remove speed limiters to lift speed restrictions, but you still need to be aware that removing speed limits brings some risks.
Safety risks: After the speed limit is lifted, electric bicycles will travel too fast, which will increase the risk of traffic accidents.
Legal issues: You can still face prosecution for speeding above local laws.
Reduced device life: The motor power limit has been removed, which will affect the life of the battery, motor, and some other parts.
Warranty Policy: The merchant’s warranty policy will not cover problems caused by illegal modifications, including lifting speed limits.
Bike damage: If you don’t do the right operation, your e-bike may malfunction, both in the controller and the motor.
If you still need to consider lifting the speed limit, we recommend that you first ask the original seller. At the same time, you should also consider the above problems that may occur after lifting the speed limit.
How To Remove The Speed Limit On Electric Bikes?
If you need to remove the speed limit, you first need to ask the original seller whether the bicycle's display and controls retain the function of removing the speed limit. If the original seller retains the function of removing the speed limit, you do not need to take any further action.
Here are the steps to remove the speed limiter:
Power off: Make sure your e-bike is off. Remove the battery if it is removable.Locate the controller: This is usually located behind the battery, in the center bottom of the bike.Locate the speed limiter: The speed limiter is usually attached to the controller. Different devices and brands use different speed limiters, you can ask the original seller.Remove the speed limiter: Disconnect the speed limiter from the controller. If the speed limiter is programmed, it is usually not possible for the user to remove the speed limit.Test the bike: Once you have completed all the work, you need to test the bike to see if the speed limit is removed and if it is working properly. Be sure to test it in a safe road environment.Kingbull does not recommend that any user remove the speed limit on an e-bike if it is not necessary. This is not only illegal, but also increases the risk of accidents.
Other Ways to Increase Speed on an E-Bike
We don't recommend anyone to remove the speed limit of an electric bike, but there are some correct ways to increase the speed of your electric bike.Battery power: Keep the battery fully charged, the voltage of the battery will affect the speed of the electric bikeChange tires: Change to tires with less resistance, such as urban tires.Riding posture: Adopt a leaning riding posture to reduce wind resistance, which can also increase your riding speed.
Speed Upgrade Controller: This is typically used for e-bikes equipped with factory-programmed speed-limited controllers that cannot be unlocked. By replacing it with a compatible new controller, you can achieve higher speed performance.
Conclusion
Removing the speed limit on an e-bike does allow you to experience faster speeds and enjoy a more exciting riding experience, but it also comes with many risks.Kingbull's e-bikes offer a maximum speed of 28mph, which can meet the riding needs of most people, combining speed and safety, and complying with legal regulations.Before making any modifications, please consider the potential risks and try other options to increase the speed of the bike.

The Secret to Smoother Rides: Understanding Electric Bike Suspension Systems
If you're into electric bikes or just getting started, you've probably wondered: why do some bikes feel like you're floating on air while others make you feel every bump in the road? The secret lies in the suspension system—the unsung hero of a smooth ride. Today, we're going to break down what you need to know about electric bike suspension systems, the different types, how to choose the right one for your ride, and some tips to keep things running smoothly.
What’s a Suspension System Anyway?
Simply put, a suspension system is your bike’s shock absorber. When you hit bumps, potholes, or rough terrain, the suspension takes the hit so you don't have to. Instead of every jolt being passed up to your hands, arms, and back, the suspension helps cushion the blow, making your ride feel a lot smoother.
There are two main types of suspension you'll find on electric bikes:
Front Suspension (Fork Suspension): This is the most common type and is installed on the front wheel. Since most of the bumps hit your bike from the front, a good front suspension helps keep the ride comfortable by absorbing shocks before they reach your handlebars. A solid front suspension means your arms won't feel like they've done a workout after every ride!
Rear Suspension: You’ll find rear suspension on more rugged, off-road electric bikes. If you're the kind of person who loves the thrill of tackling mountain trails or bumpy backroads, rear suspension keeps the back half of your bike steady and helps you stay in control no matter how rough the terrain gets.
Types of Suspension: Spring vs. Hydraulic
Now, not all suspension systems are created equal. The two big players in the suspension game are spring suspension and hydraulic suspension. They both absorb shocks, but they do it a little differently.
Spring Suspension: This is the old-school kind, using metal springs to take the brunt of the impact. It’s reliable and durable, but sometimes it can feel a bit stiff, especially when you hit larger bumps. You’ll notice the difference, but it might not completely erase the jolt.
Hydraulic Suspension: This is where things get fancy. Hydraulic suspension uses compressed fluid to cushion the ride, giving you a smoother and more responsive experience. It's like the luxury version of suspension—soft, controlled, and perfect for riders who crave comfort across all terrains. Riding a bike with hydraulic suspension feels more like driving a cushy SUV than a bumpy bicycle.
Tips for Choosing the Right Suspension
When it comes to choosing the right suspension for your electric bike, it’s all about matching it to your riding style. Here are a few quick tips:
For City Commuters: If you're mostly cruising through city streets, a good front suspension will do the trick. It’ll help you glide over cracks, potholes, and speed bumps without feeling like you're riding a jackhammer. Luckily, all Kingbull electric bikes come equipped with high-performance front suspensions, ensuring a smooth and comfy ride no matter what the city throws at you.
For Off-Road Adventurers: If your idea of fun involves taking on rough trails, rocky paths, or sandy beaches, then a front and rear suspension combo is your best bet. This setup gives you the balance and control you need for tackling unpredictable terrain without losing your cool. Our Kingbull Rover off-road electric bike, for example, comes with both front and rear suspension, so you’re ready for anything—from mountain biking to beach riding.
Is Hydraulic Suspension Worth It?: If you’re serious about comfort or plan to ride on a variety of surfaces, hydraulic suspension is worth every penny. The hydraulic front suspension in Kingbull electric bikes delivers a silky-smooth ride—whether you're commuting or exploring off the beaten path. While it costs a bit more, the performance boost and durability make it an investment that pays off with every ride.
Maintenance Tips for Your Suspension
Your bike’s suspension system might not get as much attention as other parts, but it works hard to keep you comfortable. Here are some quick tips to keep your suspension in tip-top shape:
Keep It Clean: Dirt and mud can get into your suspension and cause it to wear down faster. If you're riding through muddy areas, give your bike a quick wash afterward, especially around the suspension.
Regular Checkups: Every few months, check how your suspension is performing. Listen for any strange noises, and pay attention to whether it feels less smooth than usual. If it seems stiff or sluggish, it might be time for some maintenance or a fluid change.
Don’t Overload It: Your suspension system has a weight limit, so be careful not to overload your bike, especially on rough rides. Too much weight can wear out your suspension faster and lead to a less comfortable ride.
The Bottom Line
A good suspension system can make all the difference between a bumpy, uncomfortable ride and a smooth, enjoyable one. Whether you're zipping through city streets or tearing up off-road trails, choosing the right suspension for your electric bike is key to making sure every ride feels like a dream. Kingbull electric bikes are equipped with high-quality hydraulic front suspensions across the board, and if you're after the ultimate off-road experience, our Rover model delivers with front and rear suspension, giving you unbeatable control and comfort on any terrain.
So, the next time you're out riding, take a moment to appreciate your suspension system—it’s the secret sauce to a smooth, effortless ride!
