Removing The Speed Limiter From An E-Bike
In general, electric bikes have a 15MPH to 20MPH speed limit in Europe and 28MPH in most states of the US. All manufacturers use a speed limiter because the vehicle must maintain the approved speed while on the roads.
Of course, it increases safety and reduces the chance of accidents. Unfortunately, it feels insufficient to many people. Are you one of those individuals looking for methods to get rid of the speed limiter? Then, follow our guidelines below.

Method 1: Handy Method
You must manually remove the speed limiter from your electric bike if you want to raise its speed. Since you will work with your hands, it is called handy or by-hand method.
Usually, a speed limiter works with a speed sensor and the central controller. When you make an effort to accelerate on your electric bike, the sensor picks up on it and notifies the controller of what’s happening. The report sent and is used to set the maximum speed limit.
Whenever you attempt to increase the speed beyond the permitted level, the controller then turns the motor off. The bike has two sensors for inspecting the speed. These are:
- A magnetic sensor in the rear wheel
- The base sensor located in the bike’s frame
All that is required is to tweak the data that is being sent to the controller from the magnetic sensor. The magnet works by counting the rotation of the wheel and its circumference. When it comes to electric bikes, the larger the wheels, the faster the bike moves.
As the wheels move, the sensor detects and reports the speed to the speed limiter. The e-bike’s motor will then be turned off . As the motor turns off, you won’t be able to use the pedal assistance (PAS).
All you have to do is move or manipulate the magnetic sensor. When you relocate the magnet from the rear wheel, it will get different readings. The magnet will then detect various speeds and send a lower speed report to the controller. As a result, it won’t turn off the assistance mode with the motor. This way, you can bypass the speed limiter.
One of the best things about this handy method is that you don’t need to change the entire electric system of your bike. You may follow these steps:
- Remove the magnet and sensor from the rear wheel
- Locate the pedal bracket on your e-bike and place the magnet there
- Then, place the sensor in a way so that it faces the magnet
The sensor will receive low signals as a result of the magnet’s displacement. Thus, it disables the speed limiter. The controller will then assume that you are riding at a slower speed. As a result, the assistance mode will not be disabled, and you will be able to fully utilize the motor’s capacity.

Method 2: Disconnect the sensor wiring
Even though the handy method for raising the speed limit is basic, it is not the most efficient. As a result, you should think about disconnecting the sensor wiring for the controller.
Unfortunately, detecting the right wire of the sensor is challenging. As a result, most riders will not use this method to unlock their bike’s speed.
You may need to check your e-bike’s user manual to locate the sensor wire. When you are sure about its location, you can cut it with pliers set.
Nonetheless, we don’t suggest you choose this method. If you accidentally cut the sensor wire, reconnecting it can be a hassle. So, when you truly want to cut the sensor wiring, consider taking it to a professional.

Method 3: Use the tuning kit
Before you choose the tuning kit to disable the limiter, you must keep two important things in mind.
- Using the tuning is a technical method. To use the tuning kit, you need to know the electric bike’s functioning system.
- Secondly, you need to spend heftily to purchase the tuning kit. So, be aware of the cost linked with the tuning kit approach.
As riders were getting agitated with the low speed of their electric bike, manufacturers introduced the tuning kit. There are two types of tuning kits available. These are:

The 1st type of e-bike tuning kit:
The first type of tuning kit often comes with the e-bike system. When you attach a tuning kit, the speed limiter gets disabled. Moreover, the good news is, you can deactivate it any time to enable the speed limiter.
Most tuning kits of this type include a shutdown system. Whenever, you want to turn it off, use the shutdown system. To activate or deactivate the tuning kit, just press the switch. As the tuning kit has the capability to control the speed limiter whenever you want is way more convenient.
The 2nd type of e-bike tuning kit:
The 2nd kind of tuning kit to disable the speed limiter is preferable. No electrical circuits need to be disassembled. Likewise, there is no need to remove the e-bike’s battery or motor housing.
All you have to do is to locate the speed limiter sensor. Then, you attach the tuning kit with it. All the tuning kits include an instruction manual with the package. If you find using the tuning kit difficult, just follow the instructions.

What Should You Consider Before Disabling The Speed Limiter?
Electric bikes have become one of the mainstream commuters in many cities recently. Yet, most countries worldwide and USA states haven’t enforced proper laws. Therefore, it is a must for riders to ride under a recommended speed in most regions.
For instance, the federal laws in America require the following rules for an electric bike:
- The motor would be 750W or less for the e-bike
- A speed limiter to limit the speed at 20MPH with assistance mode
- The pedals must be fully operational
Thus, you must look at these federal rules for the e-bike. As a result, removing or disabling the speed limiter violates federal law. If traffic police catch you, they can take necessary action. You must keep this in mind before removing it.
But that’s not all. Before removing the speed limiter, you should also take into account the following facts.

End of warranty period:
Once you disable the speed limiter, you will lose the e-bike warranty immediately. So, in case of any damages, you won’t get the free servicing or repairing anymore. This is a concerning issue because repairing any parts of an e-bike can be costly.
Restrictions on riding space:
You will be restricted from riding the e-bike on government property such as parks, national highways, etc. it will be disheartening because you will fail to ride the e-bike wherever you want. It reduces your riding fun.
Battery draining problem:
Once the speed limiter is removed, the bike will demand more power. Consequently, the motor will require more energy and will drain the battery faster. It brings a dilemma for the riders.
Since the battery drains faster, you will lose its battery range. Thus, you will fail to cover the distance you would previously do. For instance, its range may reduce from 35 miles to 30 miles. It can be truly difficult for long route riders.
As the battery serves more energy to the motor, it pressures both items. The increased load on the motor and battery will decrease their performance.
Less control and balance:
An e-bike’s braking system is designed to function in accordance with its speed limit. So, when the speed limiter is removed, the braking system may not function properly. The braking distance will increase. In return, it increases the risk of collision and accident.
Last but not least, with the increased speed, you may find controlling the e-bike difficult. The possibility of an accident rises as you lose balance while riding.
