Removing the Speed Limit on National Standard Electric Vehicles?

[Eugenia]

For ordinary and simplest electric vehicles, removing the speed limit is quite straightforward. You just need to locate the speed-limiting wire on the controller and disconnect it to lift the restriction. Electric vehicles can typically reach speeds of 30~35 kilometers per hour. However, the controllers of these new national standard electric vehicles do not come with a speed-limiting wire at all. Therefore, using this method to remove the speed limit is quite challenging. If you insist on forcibly lifting the restriction, the only option is to replace the controller with a new one.

I've dealt with many electric vehicle speed limit issues. Removing the speed limit on standard-compliant e-bikes is actually quite complex and requires starting with the controller. For some models, you can flash the ECU software or replace the speed limiter. Always disconnect the battery safety lock before working to prevent short-circuit risks. It depends on the model: some new standard-compliant e-bike controllers may have hidden interfaces that allow parameter adjustments using specialized tools connected to a computer, though this isn't recommended. Removing the limit increases speed dramatically, which extends braking distance and raises the risk of losing control. DIY attempts can also burn out the motor or battery pack—I've seen cases where motors failed within a week after modification. Legally, it's considered illegal modification, and hefty fines apply if caught by traffic police. If you're determined to proceed, find a reputable shop for testing. After modification, always check tire and brake performance—safety should always come first.

Removing the speed limit on standard electric bikes carries many risks, and I advise against attempting it lightly. The factory settings of 15-25 km/h are designed to protect the overall system. DIY modifications may damage wiring connections, leading to overheating, fires, or short circuits. I've seen too many cases: friends who altered their controllers ended up with overheated motors, stranded on the road with towing troubles. Worse, speeding increases accident risks, especially on sharp turns or slippery roads where tipping over is likely. Regulations are strict—unauthorized modifications can result in fines of thousands and penalty points. If you must proceed, use proper tools like an OBD diagnostic device to adjust parameters carefully, followed by a test drive to ensure no abnormal noises or issues. In short, prioritize safety over speed.

I'm an e-bike enthusiast who enjoys modifying bikes for fun. Removing the speed limiter on standard models is straightforward: open the plastic cover near the pedals to locate the control unit. Common methods involve soldering a bridging circuit or using programmer software to reset the speed parameter. However, when DIY testing, it's best to conduct multiple acceleration/braking tests in open areas to avoid smoking issues. I once modified one that ran blazing fast but consumed 50% more power, significantly reducing battery lifespan. Neighbors also frequently complained about the noise. Remember to perform safety checks post-modification, like brake sensitivity tests. If unsure, just pay a shop to handle it - spending a bit saves hassle.
