Component stress: Motors, brakes, and batteries aren’t designed for sustained high speeds. Over time, this can lead to premature failure.
No turning back: Some modifications are irreversible. Make sure you’re ready to commit.

If you’re under 18, consult a parent or guardian before making any changes. Always wear a helmet, knee pads, and elbow pads when testing your modified scooter.

Tools and Materials You’ll Need

You don’t need a full workshop to remove the speed limiter, but having the right tools makes the job safer and easier. Here’s what to gather:

Phillips head screwdriver: For removing screws on the deck and undercarriage.
Flathead screwdriver or plastic prying tool: To gently separate plastic panels without cracking them.
Needle-nose pliers: Useful for disconnecting small wires or clips.
Multimeter (optional but recommended): Helps verify connections and check for electrical issues.
Electrical tape or heat shrink tubing: For insulating exposed wires.
Work gloves and safety glasses: Protect your hands and eyes during disassembly.
Clean, well-lit workspace: A flat table with good lighting prevents lost screws and mistakes.

Most of these items are household tools. If you don’t have a multimeter, consider picking one up—it’s a great investment for future electronics projects.

Step-by-Step Guide to Removing the Speed Limiter

Now that you’re prepared, let’s get into the actual process. We’ll focus on the most common method: physically disconnecting the speed sensor wire. This works on most Gotrax models, including the GXL V2, G4, and G2.

Step 1: Power Off and Prepare Your Scooter

Safety first. Before touching any internal components:

Turn off the scooter completely.
Remove the key if your model has one.
Disconnect the battery if possible (some models allow this via a plug under the deck).
Place the scooter on a stable surface, preferably upside down or on a stand.

This prevents accidental activation and reduces the risk of electric shock.

Step 2: Remove the Deck Plate

The speed sensor is usually located under the deck, near the rear wheel. To access it:

Locate the screws on the underside of the deck. Most Gotrax scooters have 6–8 Phillips head screws.
Use your screwdriver to remove them carefully. Keep them in a small container so you don’t lose any.
Gently lift the deck plate. It may be held by clips or adhesive, so use a plastic prying tool to avoid cracking the plastic.

Once the plate is off, you’ll see the wiring harness, battery, and motor connections. Look for a small white or black sensor near the rear axle.

Step 3: Locate the Speed Sensor

The speed sensor is a small magnetic device that detects wheel rotation. It’s typically attached to the rear fork or axle and connected to a thin wire that runs to the controller.

Look for a small cylindrical or rectangular component with a wire leading away from it.
It’s often held in place with a zip tie or clip.
The wire usually connects to a 2- or 3-pin connector in the main wiring harness.

This sensor tells the controller how fast the wheel is spinning. When the scooter reaches the speed limit, the controller cuts power to the motor.

Step 4: Disconnect the Speed Sensor Wire

This is the key step in removing the speed limiter.

Trace the wire from the sensor to its connector in the harness.
Gently unplug the connector. Most are push-in types—squeeze the sides and pull.
If it’s tight, use needle-nose pliers to wiggle it loose.
Once disconnected, wrap the exposed end with electrical tape to prevent short circuits.

Some riders choose to cut the wire instead of unplugging it. We don’t recommend this unless you’re experienced, as it makes reversion harder and increases the risk of damage.

Step 5: Reassemble the Scooter

With the sensor disconnected, it’s time to put everything back together.

Replace the deck plate and secure it with the screws.
Make sure no wires are pinched or caught under the plate.
Double-check that all connections are tight and secure.
Reconnect the battery if you disconnected it.

Take your time. Rushing this step can lead to loose parts or electrical issues.

Step 6: Test Your Scooter

Now for the moment of truth. Power on your scooter and take it for a test ride.

Start in a safe, open area like a parking lot or empty street.
Accelerate gradually to see if the speed limiter is gone.
You should notice a smoother acceleration and a higher top speed.
Test braking and handling at higher speeds to ensure control.

If your scooter feels unstable or the motor cuts out unexpectedly, turn it off immediately and recheck your work.

Alternative Methods to Remove the Speed Limiter

Disconnecting the sensor is the most reliable method, but some riders explore other options. Here are a few alternatives—and their pros and cons.

Using a Firmware Hack or App

Some tech-savvy users have developed apps or software tools to modify Gotrax firmware and disable the speed limiter electronically.

Pros: No physical disassembly required; reversible.
Cons: Requires technical knowledge; may not work on all models; high risk of bricking the controller.

This method is not recommended for beginners. If you’re interested, research forums like Reddit’s r/electricskateboarding or e-scooter communities for user experiences.

Replacing the Controller

Another option is to install a higher-performance controller that doesn’t enforce speed limits.

Pros: Can unlock more speed and torque; customizable settings.
Cons: Expensive ($100–$200); complex installation; may require rewiring.

This is a more advanced modification and should only be attempted by experienced users or professionals.

Using a Magnet Bypass (Not Recommended)

Some riders try to trick the sensor by placing a magnet near it to simulate constant motion. This can confuse the controller and disable the limiter.

Pros: Simple and cheap.
Cons: Unreliable; can cause erratic behavior; may damage the sensor or controller.

We strongly advise against this method. It’s unsafe and can lead to unpredictable scooter behavior.

Troubleshooting Common Issues

Even with careful work, problems can arise. Here’s how to handle common issues after removing the speed limiter.

Scooter Won’t Turn On

If your scooter doesn’t power up after reassembly:

Check that the battery is properly connected.
Ensure all screws are tightened and no wires are loose.
Use a multimeter to test battery voltage (should be 36V or 48V, depending on model).
Look for blown fuses or tripped circuit breakers.

If nothing works, reconnect the speed sensor temporarily and contact Gotrax support.

Motor Cuts Out at High Speed

This could mean the controller is still detecting a fault or overheating.

Check for loose connections in the motor wires.
Ensure the motor isn’t overheating—let it cool down between tests.
Verify that the battery is fully charged.

If the issue persists, the controller may be incompatible with higher speeds.

Reduced Battery Life

Higher speeds drain the battery faster. If you notice a significant drop in range:

Avoid sustained high speeds.
Keep the battery charged between 20% and 80% for longevity.
Consider upgrading to a higher-capacity battery (if compatible).

This is a normal trade-off for increased performance.

Unusual Noises or Vibrations

If you hear grinding, clicking, or excessive vibration:

Stop riding immediately.
Check the motor mount and wheel alignment.
Inspect the chain or belt (if applicable) for wear or looseness.
Ensure all screws and bolts are tightened.

These symptoms could indicate mechanical stress from higher speeds.

Safety Tips for Riding Without a Speed Limiter

Now that your scooter is faster, it’s more important than ever to ride safely.

Wear full protective gear: Helmet, gloves, knee pads, and elbow pads are essential.
Learn to brake effectively: Practice emergency stops in a safe area. Higher speeds require longer stopping distances.
Avoid wet or uneven surfaces: Traction decreases at high speeds, increasing the risk of skidding.
Ride in bike lanes or low-traffic areas: Avoid busy streets where quick reactions are needed.
Check local laws: Some cities require speed limiters or restrict e-scooter speeds to 15 mph.
Inspect your scooter regularly: Look for loose parts, worn tires, and battery issues.

Remember: speed increases risk. Ride smart, stay alert, and respect traffic rules.

How to Revert the Changes (If Needed)

If you decide the higher speed isn’t for you, you can usually reverse the process.

Open the deck plate again.
Reconnect the speed sensor wire to its original connector.
Secure the sensor in place with a zip tie.
Reassemble the scooter and test.

Keep the original connector and tape in case you need to restore factory settings. This is especially useful if you plan to sell the scooter later.
