How to Remove the Speed Limit on New National Standard Electric Vehicles?
2 Answers
Here are methods to remove the speed limit on electric vehicles. Disconnect the Controller Speed Limit Wire: If there is a speed limit wire, you can directly disconnect it. Open the seat of the electric vehicle, locate the controller, find the two connected white plugs, and simply unplug them. Adjust the Throttle and Other Buttons: For vehicles without a speed limit wire, you can remove the speed limit by adjusting the throttle, brake, and cruise buttons. First, press and hold the cruise button, then turn the throttle to its maximum position, hold the brake, turn on the power lock, wait for 5 seconds, then release the brake first, followed by the cruise button, and finally the throttle. Generally, the speed of the electric vehicle can be restored to its maximum. Adjust the Throttle and Brake: For newer electric vehicles without a cruise button, you can remove the speed limit by adjusting the throttle and brake. Hold the brake, turn the throttle to its maximum position, then turn on the power lock, wait for 5 seconds, and then release the brake and throttle.
Removing the speed limit on new national standard e-bikes might sound cool, but as an enthusiast of e-bike modifications, I have to warn you that it's quite risky. Common methods include flashing the controller software or replacing the ECU chip to bypass the speed limiter, and some underground shops offer such services. However, this is unsafe because the vehicle design and braking system are only optimized for 25 km/h—exceeding this speed can lead to loss of control and accelerate battery degradation, increasing the risk of fire. I once tried a similar modification and ended up in an accident mid-ride, nearly getting injured. Legally, this violates the GB 17761-2018 standard, and if caught by traffic police, you could face fines of hundreds or even have your vehicle confiscated—hardly worth it. My advice is to stick with the factory settings and enjoy safe commuting without taking unnecessary risks for a momentary thrill.
