Unlock Your E-Bike Speed: How To Derestrict Electric Bike

People often ask how to make their electric bike go faster than its built-in limit. Derestricting an electric bike, also called removing the ebike speed limiter, involves changing the bike’s settings or adding a device. This lets the motor help you go faster than the speed limit set by the maker and the law, often 15.5 mph (25 km/h) in many places. This guide will explain what this means, why people do it, how it is often done, and the important things to think about, like safety and the law.

Grasping E-Bike Speed Limits

Electric bikes, or ebikes, are made to help you pedal. They have a motor that gives you a boost. But this boost stops when you reach a certain speed. This speed is set by rules in your area.

For example, in many parts of Europe and the UK, standard ebikes called pedelecs only give power up to about 15.5 miles per hour (25 kilometers per hour). In the US, this speed is often 20 mph (about 32 km/h) for Class 1 and Class 2 ebikes. Faster ebikes exist, like Class 3 in the US, which helps up to 28 mph (about 45 km/h), but these have different rules about where you can ride them and who can ride them.

The speed limit is there for safety. It also helps keep ebikes similar to regular bikes in how they are used on roads and paths. Removing this limit changes how the bike works a lot. It lets you reach speeds much higher than what the bike was designed for with motor help. This is the idea behind pedelec speed limit removal.

What Happens When You Remove the Speed Limit?

When you remove the ebike speed limiter, you are telling the bike’s motor to keep working at speeds above the usual cut-off. The motor pushes harder and longer. This means less work for you to go faster. Your electric bike speed unlock happens, letting the motor give power at higher speeds.

But there are big effects from doing this. The bike might go faster, but it was not built for these speeds. The brakes, frame, and tires might not be strong enough. Also, changing the speed limit often breaks the law.

Why People Want More Speed

Many riders want their electric bike speed unlock for different reasons:

• Faster Rides: They want to get to places quicker or keep up with faster traffic.
• Climbing Hills: More power at higher speeds can make climbing easier.
• Off-Road Use: On private land or trails where rules are different, riders might want more speed for fun or racing.
• Feeling Powerful: Some just like the idea of having a faster bike.

While these reasons exist, it is key to know the downsides. The ebike legal speed limit is a real thing with real reasons behind it.

The Big Risks of Derestricting

Changing your ebike to go faster than the law allows comes with serious risks.

H4 Legal Dangers

• Breaking the Law: Riding a derestricted ebike on public roads, bike paths, or parks is often against the law. In many places, a derestricted ebike is no longer seen as a regular ebike. It might be called a moped or motorbike.
• Fines and Penalties: If caught, you could get a large fine. The police might even take your bike away.
• No Insurance: Your bike insurance, if you have any, will likely not cover a derestricted ebike. If you have an accident, you could be in huge trouble.
• Riding Where You Shouldn’t: You might not be allowed to ride a derestricted ebike on bike paths. You might need to use the road, maybe even need a license, insurance, and helmet like a motorbike rider.

H4 Safety Dangers

• Accident Risk: Going faster means less time to react to problems. You need more distance to stop. Cars and people might not expect a bike to go so fast.
• Brakes Might Fail: Ebike brakes are made for their normal top speed. Going much faster puts much more stress on them. They might overheat, wear out fast, or fail when you need them most.
• Bike Parts Break: The frame, wheels, and other parts are built for the power and speed of a standard ebike. Higher speeds and forces from a derestricted motor can cause parts to bend or break.
• Loss of Control: At higher speeds, it is harder to steer and handle the bike, especially on rough ground or in bad weather.
• Voiding Warranty: Almost all bike makers will cancel your warranty if you derestrict your ebike. If something breaks because of the change, you have to pay for repairs yourself.

Complying with the Ebike Legal Speed Limit

It is very important to know the ebike legal speed limit where you live and where you plan to ride. These rules are different in different countries and even states or cities.

• Check Local Rules: Before thinking about changing your bike, look up the specific ebike laws in your area.
• Know Bike Classes: In places like the US, ebikes are put into classes based on speed and how the motor works. Class 1 (pedal-assist only, max 20 mph), Class 2 (adds throttle, max 20 mph), Class 3 (pedal-assist only, max 28 mph, often needs riders to be 16+). Derestricting usually makes your bike fit none of these classes.
• Private Land Only: If you derestrict your ebike, you should only ride it on private property where you have permission and no public access is allowed.

Riding a derestricted ebike in public is often treated the same as riding an unregistered, uninsured motorbike without a license. This can have major results.

Ways People Try to Derestrict Ebikes

People use different methods for ebike speed limiter removal. The way you do it often depends on the type of motor system your ebike has.

H4 Using an Ebike Tuning Kit

This is one of the most common ways people try to remove the speed limit. An ebike tuning kit is a device or piece of software that changes the signals between the motor and the display or sensor.

• How Tuning Kits Work: Most kits trick the speed sensor. The sensor tells the bike’s computer how fast the wheel is turning. A tuning kit makes the sensor report a lower speed than you are actually going. For example, if you are going 30 mph, the kit might tell the bike you are only going 15 mph. Because the bike thinks it is still below the limit, the motor keeps pushing.
• Types of Kits:
  • Plug-and-Play Kits: These are often small devices you plug into the bike’s wiring harness, usually near the motor or speed sensor. They are often easy to install (derestrict kit installation). You might need to take off a cover to get to the wires.
  • Chip Kits: These might involve adding a small chip or module that changes the data signals. They can be more complex to install.
  • Software/App Based Kits: Some systems can be changed using a special app or by changing settings on the bike’s display (ebike display settings speed), though display changes are often limited to minor tweaks or wheel size calibration, not full derestriction. True software unlocks are less common for major brands due to anti-tampering measures.
• Derestrict Kit Installation: Installing a kit usually involves finding the speed sensor wire (often coming from the rear wheel or chainstay), disconnecting it, and connecting the kit in between. Sometimes it connects elsewhere, like to the motor controller wiring. You often need basic tools like Allen keys and wire cutters. It is important to follow the kit’s specific guide, but remember, this process changes the bike’s function and legality.
• Common Brands: You can find tuning kits made for specific motor systems, like Bosch ebike derestriction kits or devices for Bafang ebike unlock speed. Different kits work differently and have different effects on the display speed reading (some might show half speed, others a fixed speed, or might show the correct speed but require a key code).

H4 Ebike Controller Upgrade or Firmware Changes

The controller is the brain of the ebike system. It tells the motor what to do based on your pedaling, speed, and other inputs.

• Replacing the Controller: Some people replace the original controller with an aftermarket one that has a higher speed limit or no limit at all. This is a more complex change. The new controller must be compatible with your motor, battery, and display, which is not always easy.
• Changing Firmware: Firmware is the software inside the controller or motor. In some cases, it might be possible to change or “flash” the firmware to remove the speed limit. This often requires special tools and knowledge. It is high risk and can easily “brick” (permanently damage) the controller or motor. This is often difficult or impossible with major brand systems like Bosch or Shimano due to security features.

H4 Adjusting Ebike Display Settings Speed

Some ebikes let you change settings through the display. This might include wheel size or maximum speed.

• Limited Changes: While you can sometimes change the maximum speed setting here, this often only lets you pick from a few options set by the maker. It usually does not remove the core speed limit imposed by law. It might let you set the limit lower, but not higher than the designed maximum assistance speed.
• Calibration vs. Derestriction: Changing wheel size settings can trick the bike into thinking it is going slower, but this also makes your speed and distance readings wrong. It is not a proper derestriction method and messes up your display info.

H4 Specific Motor Systems: Bosch and Bafang

• Bosch Ebike Derestriction: Bosch is a major ebike motor maker. Their systems are known for being hard to tamper with. Bosch ebike derestriction usually requires specific tuning kits designed to work with Bosch motors and their anti-tuning software updates. These kits often cost more and must be compatible with your specific Bosch motor generation (Active Line, Performance Line, CX Gen 4, etc.). Using the wrong kit or installing it wrong can cause errors on the display (like a 504 error) or limit power.
• Bafang Ebike Unlock Speed: Bafang makes many types of ebike motors, including hub motors and mid-drive motors. Bafang systems are sometimes seen as easier to change. For certain Bafang controllers (especially aftermarket ones like the controllers for the popular BBSHD or BBS02 mid-drives), you can sometimes connect to the controller with a computer cable and use special software to change settings like maximum speed, power levels, and current limits. This is a type of ebike controller upgrade or firmware change. However, even with Bafang, the specific model matters.

Interpreting How Derestriction Works

At its heart, derestriction works by tricking the bike’s system. The ebike motor controller gets information from different parts:

• Speed Sensor: Tells the controller how fast the bike is going.
• Cadence Sensor: Tells the controller if you are pedaling and how fast.
• Torque Sensor (on some bikes): Tells the controller how hard you are pedaling.

The controller uses this data to decide how much power the motor should give. When the speed sensor reports a speed over the legal limit (like 15.5 mph or 25 km/h), the controller is programmed to stop giving motor power.

A tuning kit or other derestriction method changes the speed signal from the sensor before it reaches the controller. It makes the controller think the bike is going slower than it really is. For instance, it might cut the speed signal in half. If you are riding at 30 mph, the sensor measures 30 mph, but the tuning kit changes the signal to say 15 mph. The controller sees 15 mph (which is below the limit) and keeps the motor running.

This is why your display might show the wrong speed after derestricting. The display gets its speed info from the same signal the controller uses. If the signal is halved, your display shows half your real speed. Some advanced tuning kits try to correct the display speed, but this makes the kit more complex.

Overview of Derestrict Kit Installation (General Steps)

Please note: This section gives a general idea of what installing a kit might involve. It is not a step-by-step guide on how to perform an illegal modification. The exact steps vary a lot based on your bike and the specific kit.

Getting a derestrict kit onto your bike usually involves working with the bike’s wiring.

1. Find the Speed Sensor: The speed sensor is often on the rear chainstay, pointing at a magnet on a spoke of the rear wheel. Follow the wire from the sensor back towards the motor or controller.
2. Access Wiring: You might need to remove plastic covers around the motor or controller to get to the wiring harness.
3. Disconnect Sensor Wire: The kit needs to be placed between the sensor and the controller. You will likely need to disconnect the wire that runs from the speed sensor.
4. Connect the Kit: Plug the kit into the disconnected wires. The kit has wires or connectors to go between the sensor and the main wiring harness.
5. Secure the Kit and Wires: Once connected, make sure the kit and all wires are tucked away safely. Use zip ties to keep them from rubbing or getting caught. Put covers back on.
6. Test (Carefully): Turn on the bike. Check the display. Does it show a speed? Does the motor assist? You would then test pedal assistance, likely noticing that the motor continues to assist past the original speed limit.

This process requires some comfort working with bike parts and electrical connectors. If done wrong, you could damage the bike’s electronics.

Considering Safety at Higher Speeds

Derestricting an ebike turns it into a much faster vehicle. This means you must think about safety much more seriously.

H4 Higher Speed, Higher Forces

When you double your speed, the energy involved in a crash goes up by four times. This means crashes are much more dangerous. Stopping takes much longer.

H4 Bike Parts Under Stress

• Brakes: Standard ebike brakes are made for lower speeds. At higher speeds, they get hot faster and lose stopping power (fade). You might need much stronger brakes, like those found on motorbikes, but installing these on a bike frame is complex and expensive.
• Tires: Bike tires are not designed for continuous high speeds like car or motorbike tires. They can wear out much faster or even fail.
• Frame: The frame is built to handle certain forces from pedaling and the motor at its intended speed. Higher speeds and a motor pushing harder puts extra stress on the frame, especially on bumps.
• Suspension: If your bike has suspension, it is tuned for bike speeds, not motorbike speeds. It might not handle bumps well at high speed, leading to loss of control.

H4 Rider Skill Needed

Riding safely at 30 mph or more requires skill and experience far beyond normal cycling. You need quick reactions, good balance, and a strong sense of road awareness.

Looking at Alternatives to Derestriction

If you want to go faster or have an easier ride, but want to stay safe and legal, consider other options.

• Ride Harder: The motor assists your pedaling. If you pedal harder and faster yourself, you can reach and maintain higher speeds, even above the motor’s cut-off speed, using your own power.
• Lighter Bike: A lighter bike takes less energy to move and speed up.
• Better Tires: Low-rolling-resistance tires can make pedaling easier and faster. Proper tire pressure also helps.
• Check Your Bike: Make sure your tires are full, your brakes are adjusted, and your chain is clean and oiled. A well-kept bike is more efficient.
• Choose a Different Ebike: If the legal speed limit for standard ebikes in your area is too slow for you, look into other classes of electric vehicles if they are legal and appropriate for where you want to ride. For example, a Class 3 ebike might offer assistance up to 28 mph legally in some places. Mopeds or motorbikes are designed for higher speeds and come with the necessary safety features, registration, and insurance requirements.

Trying to make a standard ebike into something it is not designed to be (a high-speed vehicle) is risky and usually illegal.

Final Thoughts on Ebike Speed Limiter Removal

While removing the ebike speed limiter might seem like a simple way to go faster, it changes your ebike into a different type of vehicle in the eyes of the law and in terms of safety. Derestricting can involve using an ebike tuning kit, looking into an ebike controller upgrade, or attempting changes via ebike display settings speed. Methods vary for different motor systems like Bosch ebike derestriction or Bafang ebike unlock speed. The physical process, like derestrict kit installation, changes the bike’s wiring.

However, ignoring the ebike legal speed limit brings major risks: huge fines, legal problems, no insurance cover, and the chance of serious accidents due to bike parts failing or loss of control. A pedelec speed limit removal makes your bike no longer a legal pedelec.

For most riders, especially those using their bikes on public roads or paths, staying within the legal speed limit is the safest and smartest choice. If you need more speed, think about getting a bike legally designed for it or improving your own pedaling power.

Frequently Asked Questions (FAQ)

Q: Is it legal to derestrict my ebike?

A: In almost all places, it is illegal to ride a derestricted ebike on public roads, paths, or parks. It might be legal only on private land with the owner’s permission.

Q: Will derestricting my ebike damage it?

A: Yes, it can. Running the motor at higher speeds and putting extra stress on the bike’s parts (brakes, frame, wheels) can cause them to wear out faster or break. It also almost always voids your warranty.

Q: Does a tuning kit make my ebike a motorbike?

A: When you derestrict an ebike, it no longer meets the legal definition of an ebike in many places. It might then be classified as a moped or motorbike, which requires registration, insurance, different helmets, and a license to ride legally on public roads.

Q: Can I just change settings on my display to go faster?

A: Some ebikes let you change a max speed setting on the display (ebike display settings speed), but this is often limited by the maker and usually does not allow you to go past the legal assist speed limit. True derestriction often requires a separate device or software change.

Q: What is the difference between a tuning kit and a controller upgrade?

A: An ebike tuning kit usually tricks the speed sensor signal. An ebike controller upgrade involves changing or reprogramming the bike’s main computer (the controller) itself to change how the motor works. Tuning kits are generally easier to install (derestrict kit installation) but might be detected. Controller upgrades are more complex but can offer more changes if possible.

Q: Will derestricting make my battery run out faster?

A: Yes. The motor works harder and longer to push you to higher speeds, using a lot more battery power than riding within the legal limit.

Q: Are Bosch or Bafang motors easy to derestrict?

A: It depends on the specific motor model and generation. Bosch systems are known for having strong anti-tuning measures, often requiring specific Bosch ebike derestriction kits. Some Bafang motors (especially older or aftermarket ones) might be changed more easily with software (Bafang ebike unlock speed), but newer Bafang motors also have security features. It is never guaranteed and always has risks.
