How to Remove Speed Limiter on Electric Bike?

Developed as alternative transportation, the use of electric bikes is growing. You can use an e-bike because you want to enjoy some riding pleasure, or you don’t want to use a car. But why are most riders concerned about how to remove the speed limiter on electric bikes?

Knowing fully well that over-speeding while riding an electric bike can be dangerous for everyone on the road, whether they are riders or pedestrians? Well, to some riders, the speed limiter does not allow them the total amount of their riding pleasure; they want it taken off, so they can enjoy riding at full speed.

As much as you may want to enjoy riding at full speed, you need to understand that injuries caused by e-bikes have grown. They accounted for approximately 3,075 out of the 245 million cases of injuries recorded during a recent study. Electric bikes were manufactured with speed limiters to help avert such a rate of injury. Speed limiters help riders manage their riding by putting the speed under a controllable range.

Key Points!

  • Derestricting Your E-Bike Gives You the Freedom of Full Riding Pleasure!
  • It Gives You Total Control Over Your E-Bike and Not the Other Way Round!
  • You Can Ride Your E-Bike at Any Speed You Want!

What Is a Speed Limiter on an E-Bike?

Speed limiters are one-of-a-kind devices mounted on electric bikes. These speed limiters prevent electric bikes from exceeding the acceptable or lawful speed. For example, suppose the United States speed limit is around 20 mph, and the Europe speed limit is 15 mph. While manufacturing and installing these limiters in their bikes, they can adapt to individual legislation. Governments insisted on adding speed limiters to make all-electric bikes street legal and law-abiding. Also, to keep the rate of bicycle-related injuries down.

Speed Limiter on an E-Bike

To better understand how speed limiters work, you must first understand how to calculate an e- bike’s speed. To determine the speed of an e-bike, they employ a magnetic speed detector mounted on the rear wheel of the e-bike. Usually, the e-bike is pre-programmed to a maximum speed, and once reached, the motor shuts down. It is advised for buyers of e-bikes to check the regulations of their respective countries of use.

The U.S. government, for example, legalizes only electric bikes that do not exceed 20 mph. When you attain this limit, the speed limiter shuts down the motor. Nevertheless, you can ride an e-bike at any speed on your property while driving in the mountains or off-road.

Things to Know Before Starting

For attempting de-restriction, keep in mind that the process will essentially differ from one machine to the next based on the brand of the e-bike. As a result, a tuning technique that works on one assist system might not work on another.

Things to Know Remove Speed Limiter on Electric Bike

It is critical to investigate the motor of your e-bike to select the proper de-restriction procedure. E-bikes that use hub system motors are typically more complex and often impossible to de-restrict. In contrast, those that use pedal motors are relatively simple to de-restrict. Regardless of the model, there are always de-restriction alternatives which can help you unlock your bike’s speed limits.

This procedure, in most instances, can be performed by anyone, including those with no prior experience with electronics. You must follow the tuning instructions, and everything should go as planned. Even so, before you de-restrict your e-bike, you should be aware of the following:

  •  The disadvantages and the procedure’s legality, such as restrictions of use and local laws
  • Your area’s legal speed limit and penalties for exceeding
  • You might very well nullify your bike’s warranty, and this will also restrict your chances of future customer service.

Let’s start the process:

How to Remove Speed Limiter on Electric Bike?

Removing an electric bike’s speed limiter is also known as “De-restricting Your Bike.” This process of de-restricting your bike can be performed in two ways:

How to Remove Speed Limiter on Electric Bike

  •  Manually, or
  • Using special e-bike toolkits

Both methods are straightforward to implement. Be prepared, however, to De-restrict, as we will explain shortly. But before we dive into it, let’s first investigate the possible technologies that can work for the model of your e-bike.

1. Manual De-restriction

With this procedure, you do not need any peculiar hardware to adjust the e-bike’s speed limit. With this method, you can manually change the sensor’s speed reading to change how the transmitter transmits information to the controller.

Switch the Sensor Elements –

With most e-bikes, the sensor elements comprise of the sensor located on the frame and an adjoining magnet situated on a rear wheel’s spokes. The first thing to do is to count the number of cycles done by the magnet since it rotates around the axial direction of the wheel. Keep in mind that the larger the wheel, the faster the machine moves.

Switch the Sensor Elements

When you move your e-bike’s magnetic sensor from your bike’s wheel to somewhere else, you cause the speed detector to misread the numbers. Moving the sensor can achieve this by placing your e-bike’s sensor on your pedal. The pedal then rotates slower than the wheels. These changes will send the controller a lower frequency magnetic rotation signal, which means a lower speed than it is (according to the sensor). Here is how:

  • You must make sure that alterations to the wheel of your e-bike and the electrical system are completed in order.
  •  Keep the components of your e-bike in place by using some tapes and an Allen key.
  • Carefully relocate the sensor and the wheel magnet. (For optimal result, you can remove the original magnet of your e-bike and replace it with a neodymium magnet).
  •  Now, place the magnet within your e-bike’s pedal bracket and ensure it is well fitted.
  • After that, look for a convenient part and transfer the sensor; make sure you rotate the sensor sideways to face the pedal bracket. And you are good to go.
  • This process will work most of the time, but if your result or performance is not satisfactory, don’t panic. All you need to do at this point is adjust the location of your sensor, and keep adjusting and testing the performance until your result is satisfactory.

Disconnection Of the Sensor Cables –

This is also a manual and the easiest de-restriction method that most e-bikers employ when de-restricting their e-bikes. When you disconnect the sensor cables of your e-bike, it puts the speedometer of your e-bike reading constantly at zero. This way, even if your speed goes above 25km/h, the speed assistance of your e-bike system will not cut your speed. But you must know which specific cable to disconnect because the process is non-reversible. Therefore, you must find and disconnect just the cables connecting the speed sensor and non-others.

2. Using Special E-Bike Tool kit

These are mechanical instruments explicitly manufactured to improve the performance and speed of your e-bike. With this tool kit, you wouldn’t need any delimitation techniques that may leave your machine unusable. This method is professional and very simple for e-bikers to enhance their e-bike’s speed potential, and it does not ask for too much effort or poses any risk. Because of the simplicity and affordability of this method, it has become commonplace for both city riders and mountain bikers.

Like with the manual method, the method follows the same trail of getting the system controller to notice that the machine’s speed is below the highest assisted speed of your e-bike. This false information sent to the controller forces the motor to release more power, enabling your e-bike to keep running at high speed. This method equally allows you to re-instate the normal cycling mode of your e-bike with just a touch of one button.

Downsides of Removing Speed Limiter on Your E-Bike

Conclusion: there are downsides to de-restriction, which are overlooked by e-bikers who are looking for how to de-restrict e-bikes. The first one is this is a significant increase in speed while on the road. We already talked about the risk and dangers of riding at high speed. Higher speeds can increase the risks of you hurting yourself, losing control, running into pedestrians, or even running a pedestrian over.

Downsides of Removing Speed Limiter on Your E-Bike

Another risk is the brake distance limit. While riding on the road, the regulation demands that you correctly analyze or compute the proper braking distance. Failure to do so may very well result in injury as well. Your e-bike’s original brakes are installed and adjusted to ensure speed within the correct range. Tampering with it may create unknown faults that may cause it to stop working correctly, especially when you are at high speed.

Remember, taking off the speed limiter on the e-bike does not add to your bike’s power. It only disengages the speed restriction on your e-bike.

How Do You Bypass the Speed Limiter on an E-bike?

Provided your e-bike has a display, you can change the wheel’s circumference to a smaller size. The following method may not be easy, but it is worth trying. This method works well for e-bikes without proprietary motors such as Yamaha or Bosch. Reprogramming of all the speed controllers or use a controller with a higher speed that will provide more amps and volts, resulting in increased torque and power. When you buy a Do-It-Yourself kit, you get more flexibility than commercial e-bikes. On top of that, most e-bike brands producing e-bikes below the $2000 price range are all using Chinese kits, be it controller, motor, or battery.

Summary

Getting rid of a speed limiter is a simple process but, on the other hand, may not be a good idea because you may end up endangering yourself and those around you. But if you must do it, then it is preferable to first learn about the laws governing the speed of electric bikes in your state before deciding whether to remove them. And if you finally decide to go ahead and de-restrict your e-bike, you can do so manually or with a tool kit. Manual de-restriction and tool kits are all effective methods, and most are safe, while others may leave the aftermath if you don’t know what to do. Make sure you are doing the right thing.
