Gotrax includes speed limiters on their scooters for several important reasons. First, it helps them meet legal requirements in many regions. In the U.S., for example, electric scooters are often classified as low-speed vehicles when capped at 20 mph or below. By limiting speed to 15 mph, Gotrax ensures their scooters can be legally ridden on sidewalks, bike lanes, and public paths in many cities.
Second, speed limiters protect the scooter’s components. Electric motors, batteries, and brakes are designed to handle certain stress levels. Pushing beyond factory settings can overheat the motor, drain the battery faster, or cause brake failure.
Finally, speed limits improve rider safety. Newer riders benefit from a controlled, manageable speed while they learn balance and handling. But once you’re confident and experienced, you may want more power—and that’s where removing the limiter comes in.
Is It Legal to Remove the Speed Limiter?
This is a critical question. In many places, riding an electric scooter above 15–20 mph on public roads or sidewalks is illegal. Some cities require scooters to have speed governors, and modifying them could result in fines or confiscation.
Before you proceed, check your local regulations. In the U.S., laws vary by state and city. For example, California allows scooters up to 20 mph on bike lanes, while New York City has stricter rules. In Europe, the EU limits e-scooters to 25 km/h (about 15.5 mph).
If you plan to ride only on private property—like a large backyard, closed track, or private community—you may have more freedom. But always prioritize safety and legality.
Tools and Materials You’ll Need
Removing the Gotrax speed limiter typically involves accessing the scooter’s controller or firmware. Here’s what you’ll need:
- Computer (Windows or Mac): Needed to run flashing software.
- USB to UART TTL cable: This connects your scooter’s controller to your computer. Look for a CP2102 or FTDI-based cable.
- Screwdrivers: Phillips and flathead, usually size #1 or #2.
- Multimeter (optional but recommended): Helps verify connections and voltage.
- Electrical tape or heat shrink tubing: For insulating exposed wires.
- Firmware flashing software: Such as Arduino IDE, ESP Flash Tool, or Gotrax-specific tools (if available).
- Backup battery or power source: To keep the scooter powered during the process.
You can find most of these tools online or at electronics stores. The USB TTL cable is the most critical—make sure it’s compatible with your scooter’s controller chip.
Step-by-Step Guide: Removing the Speed Limiter on Gotrax GXL V2
The Gotrax GXL V2 is one of the most popular models, and many riders seek to remove its 15 mph limit. Here’s how to do it safely.
Step 1: Prepare Your Workspace
Find a clean, well-lit area to work. Lay down a soft cloth or mat to protect the scooter’s finish. Make sure the scooter is turned off and the battery is disconnected if possible.
Step 2: Locate the Controller
The controller is usually housed under the deck plate. On the GXL V2, remove the four screws on the underside of the deck using a Phillips screwdriver. Carefully lift the plate to expose the controller—a small circuit board with wires connected to the motor, battery, and throttle.
Step 3: Identify the UART Pins
Look for a set of four pins labeled TX, RX, GND, and VCC. These are the UART (Universal Asynchronous Receiver-Transmitter) pins used for communication. If they’re not labeled, refer to online diagrams or community forums for your specific model.
Step 4: Connect the USB TTL Cable
Match the wires from your USB TTL cable to the controller pins:
- TX (cable) → RX (controller)
- RX (cable) → TX (controller)
- GND → GND
- VCC → VCC (only if needed for power)
Important: Double-check the connections. Reversing TX and RX is common but fixable. Never connect VCC unless you’re sure the controller needs external power.
Step 5: Power On and Connect
Plug the USB cable into your computer. Turn on the scooter (or connect the battery). Open your flashing software—such as ESP Flash Tool—and select the correct COM port. The software should detect the controller.
Step 6: Backup Original Firmware
Before making any changes, always backup the original firmware. This allows you to restore the scooter if something goes wrong. In the flashing software, select “Read” or “Backup” and save the file to your computer.
Step 7: Flash Modified Firmware
Now, load a modified firmware file that removes the speed limiter. These files are often shared in online communities like Reddit’s r/electricscooters or specialized forums. Make sure the file matches your exact model and controller version.
In the flashing software, select the new firmware file and click “Flash” or “Write.” The process may take 30–60 seconds. Do not disconnect during this time.
Step 8: Disconnect and Reassemble
Once flashing is complete, safely disconnect the USB cable. Turn off the scooter. Carefully reconnect the deck plate and secure it with screws.
Step 9: Test the Scooter
Take your scooter to a safe, open area—like an empty parking lot. Turn it on and test the throttle gradually. You should notice a significant increase in top speed, potentially up to 20–22 mph depending on conditions.
Alternative Method: Using a Speed Unlock App (If Available)
Some Gotrax models, particularly newer ones, may support Bluetooth connectivity via a smartphone app. While Gotrax’s official app doesn’t allow speed adjustments, third-party apps or modified firmware might offer this feature.
Step 1: Check for Bluetooth Compatibility
Look for a Bluetooth module near the controller. If present, your scooter may be compatible with apps like “Scooter Hacking” or “ES-Tool.”
Step 2: Download and Install the App
Search for trusted apps on Google Play or the App Store. Read reviews and ensure the app supports your Gotrax model.
Step 3: Pair and Adjust Settings
Open the app, pair with your scooter, and navigate to speed settings. Some apps allow you to disable the limiter or increase the max speed. Save the changes and test.
Note: This method is less reliable and may not work on all models. Always backup settings first.
Model-Specific Instructions
Different Gotrax models have different controllers and firmware. Here’s a quick breakdown:
Gotrax G2
The G2 uses a similar controller to the GXL V2. Follow the same UART flashing method. However, some G2 units have updated firmware that’s harder to modify. Check online forums for the latest patches.
Gotrax G4
The G4 has a more advanced controller with Bluetooth and app integration. Some users report success using the “ES-Tool” app to adjust speed limits. Others use UART flashing, but the process is more complex due to encryption.
Gotrax XR and XR Ultra
These models have higher base speeds (up to 18 mph), but the limiter can still be removed. The process is similar to the GXL, but ensure you have the correct firmware version.
Safety Tips and Best Practices
Removing the speed limiter increases risk. Follow these tips to stay safe:
- Wear protective gear: Always wear a helmet, knee pads, and elbow pads when testing higher speeds.
