Electric bikes, or e-bikes, have become increasingly popular among riders due to their convenience and eco-friendliness. However, some riders may feel limited by the speed restrictions imposed on their e-bikes. Luckily, there are ways to unlock an e-bike’s motor and remove the speed limiter, allowing for higher speeds and improved performance. In this article, we will discuss the process of unlocking an e-bike’s motor and the potential benefits and drawbacks of doing so. So, if you’re curious about how to unlock your e-bike’s motor and remove the speed limiter, read on to learn more.
What is de-restricting an Electric Bike?
De-restricting an electric bike involves removing the pedal assistance limit, which allows the motor to release all of its electrical power and increase the bike’s speed beyond its original limit. Normally, an electric bike delivered in compliance with regulations is equipped with a 250-watt motor that provides assistance up to 25 km/h. The limit is not due to the motor itself, but rather a manufacturer-imposed restriction integrated into the motor.
Why remove an e-bike speed limiter?
There are various reasons why an individual might consider unlocking their e-bike speed limit. By doing so, they can enhance the bike’s speed and efficiency, resulting in an increased top speed. Unlocking the motor can also lead to better acceleration and overall performance, enabling riders to travel longer distances in less time.
However, it is important to note that removing the pedal assist limit can be risky, as it can damage your bike’s motor, reduce battery life and lead to legal issues. It is essential that you prioritize safety and comply with local regulations when modifying and using your e-bike. As a reminder, the installation and use of an unlocking product is at the user’s own risk.
How does unlocking work?
Unlocking an e-bike’s motor involves removing the pedal assistance limit that is imposed by the manufacturer. This limit is put in place to prevent the release of all the electrical power from the motor, keeping the bike’s speed below a certain limit, usually 20 mph or 25 km/h.
De-restricting an electric bike involves manipulating the electronic controller by providing it with false information, allowing the motor to provide assistance beyond the original limit of 25 km/h. However, when the pedal assist limit is completely removed, the assisted speed is limited only by the maximum power the motor can provide.
It is important to keep in mind that the de-restriction process to remove the speed limit on an electric bike can vary in complexity depending on the type of motor. What may work for one electric bike may not necessarily work for another, which is why it is crucial to research your specific motor and choose the appropriate de-restriction technique.
Understanding the Types of E-Bike Motors
E-bike motors are a crucial component that determines the speed, range, and power output of the bike.
There are two main types of e-bike motors: hub motors and mid-drive motors :
The hub motor is located in the center of the rear or front wheel and powers it directly. These motors are known to be relatively simple to install and require less maintenance than intermediate drive motors. In addition, they are a cheaper option for electric bike enthusiasts.
Mid-drive motors are located in the center of the bike frame and power the crankshaft, which drives the chain to the rear wheel. These motors are known for their superior torque and efficiency, making them an excellent choice for tackling steep hills and rough terrain.
Important factors to consider before unlocking your E-bike
Unlocking your electric bike can be an appealing option for those seeking higher speeds than the designated 20 mph limit. However, it’s important to understand the implications of unlocking an e-bike, as there are several negative consequences to consider.
One of the main reasons riders choose to unlock their e-bikes is to access higher speeds. However, this increased acceleration and reliance on the e-bike motor can lead to a shorter battery life, requiring more frequent charging or potentially leaving you stranded without enough battery life to make it back home.
Additionally, unlocking an e-bike can void the manufacturer’s warranty, leaving you responsible for any repair costs that could have been covered by the manufacturer. Riding an e-bike at high speeds can also increase the risk of injury, as higher speeds can make it more difficult to control the bike and navigate traffic.
Furthermore, unlocking an e-bike to ride faster than the legal speed limit is illegal in most regions, meaning you could receive a ticket or other legal consequences for doing so. Before attempting to unlock your e-bike, it’s important to consider these factors and evaluate the impact on power consumption, battery usage, and circuitry strain.
Overall, unlocking an e-bike is not recommended, and riders should be aware of the potential risks and negative consequences before attempting to do so. It’s important to prioritize safety and abide by legal regulations when operating an e-bike.
How to remove e-bike speed limiter?
E-bikes have become increasingly popular in recent years, and many riders want to unleash the potential of their electric bike by removing the speed limiter. This process, known as unlocking, tuning, or de-restriction, involves removing the limit set by the manufacturer to prevent the release of all electrical energy from the motor. By de-restricting an electric bicycle, the motor can deliver more power and reach higher speeds.
To quickly unlock your electric bike, there are two common methods, which we will look at in detail.
Method 1: Removing the rear wheel magnet
This method involves unlocking the electric bike’s gear by focusing on the base sensor. However, this mechanical approach may not work for all e-bike models, as it depends on whether your e-bike allows it or not.
The function of the sensor is to record the current state of the bike and transmit this data to the control software, which decodes the information and controls the amount of electric assistance provided by the motor. To change the speed limit, simply change the interaction between the sensor and the electric bike controller.
E-bikes with larger wheels generally travel faster, and the speed is usually measured by the circumference of the wheels. A magnet is located under the frame near the rear wheel. By moving this magnet, you can change the number of times it turns the wheel as you move forward.
By moving the magnet, you cause the computer to calculate a lower speed than the one you are actually riding at. This allows you to de-accelerate your electric bike without having to dismantle anything from the machine. Follow the steps below to apply this method:
- Remove the magnet and the base sensor from their preset positions.
- Place the magnet on the pedal bracket of your electric bicycle.
- Attach the sensor so that it faces the magnet.
Method 2: Using an adjustment tool kit
Another way to adjust the maximum speed of your electric bike is to use an adjustment kit. Although this method is more technical and expensive than the previous one, it is still a feasible option.
After many users complained about the speed limits, electric bike manufacturers developed adjustment kits to solve the problem. One of the advantages of this method is that it is always possible to return the electric bike to normal operation by deactivating the effects of the kit.
There are generally two types of gear release kits, one that requires disassembly of the circuit and one that does not. Once you have access to these kits, using them is relatively simple and should not be too difficult. You will also receive a user manual with all the necessary details, so you will be covered in all respects.
Important optimizations for efficient e-bike unlocking
An important, but often neglected, element in the discussion of e-bike unlocking is the optimization of the mechanisms to ensure the reliability of the unboxing. Indeed, the effects of an increase in bike power are also felt in the hardware. Just like battery wear, some parts of the vehicle can wear out faster than others.
Here’s a short list of changes you can make to avoid these drawbacks:
- Choose a larger chainwheel: Unlocking your e-bike increases your speed, which results in a higher pedaling cadence. A chainwheel with a larger diameter (with more teeth) will be more comfortable at high speed. It will also wear out less quickly.
- Increase the chain size: This change is mandatory after the chainwheel modification.
- Revise the structure of the fork: The premature wear of the fork is one of the main constraints that you could face after a debriding. This part is indeed more stressed when the bike is ridden more regularly at high average speeds.
- Adjust the tire pressure by increasing it slightly.
Is it necessary to change the battery?
Indeed, it is another crucial element to be taken into account when one wishes to debride an electric bicycle. Indeed, the use of an electric assistance at high speed requires a consequent power, which results in an increased consumption of electric energy. As a result, the initial battery life may be reduced due to the new demands on the motor. In short, by using more motor power, you also consume more energy stored in your battery.
Unlocking an e-bike motor can be a great way to improve its speed and performance. However, it’s important to be aware of the legalities in your area and take the necessary precautions to ensure your safety. By following the steps outlined in this article, you can safely and effectively unlock your e-bike motor and enjoy a faster, more efficient ride.
