Can the New National Standard Remove Speed Limits?

[Nicole]

New national standard can remove speed limits. Here is an introduction about removing speed limits under the new national standard: Replacing the new controller: Users should note that although replacing the new controller can remove speed limits, this behavior is not allowed. From a safety perspective, although the speed of the modified vehicle increases, the safety performance cannot be guaranteed. Moreover, in case of an accident, such modified vehicles will bear the main responsibility. Unplugging the speed limit line: To remove the speed limit, general users can find the speed limit line on the controller and unplug it to remove the speed limit. Generally, after removing the speed limit, the speed can reach 30-35km/h.

I was curious about this before and specifically looked up the new national standards. The national standard for electric bicycles requires that the maximum speed cannot exceed 25 kilometers per hour, and there must be anti-tampering designs. Manufacturers have implemented hardware limitations at the factory, with speed caps set in the controller. Some people think they can remove the limit by cutting a wire or flashing a program, but it's actually impossible. First, this behavior itself is illegal, and traffic police will treat it as illegal modification if caught; second, after removing the limit, the bike is prone to malfunctions, and the braking system can't keep up with the speed, which is particularly dangerous; moreover, once the limit is removed, it no longer counts as a non-motor vehicle and requires a driver's license and registration, which is a huge hassle. In my opinion, it's better to ride as is—safety first.

Let's look at this issue from a practical perspective. The 25 km/h speed limit for new national standard electric vehicles isn't deliberately set by manufacturers - it's designed with safety considerations in mind: frame strength and braking distance are all calculated based on this standard. I've personally seen cases where people insisted on removing the speed limiter, only to lose control on downhill slopes and crash. Moreover, removing the speed limiter severely damages the vehicle - not only does it drain the battery faster, but the motor is prone to overheating and burning out. Current regulations are very strict, with manufacturers implementing dual encryption in the controllers that ordinary repair shops simply can't bypass. If you really want faster speeds, you'd be better off directly purchasing an electric motorcycle. Although it requires registration and a driver's license, at least it's legal and safe.

Let me address this in three points: First, removing the speed limit on new national standard e-bikes is considered illegal modification, and if caught, the vehicle will be impounded with fines imposed. Second, once the speed limit is removed and the speed exceeds the standard, it will be classified as a motor vehicle, requiring insurance and a driver's license. Third, and most importantly, it's dangerous—a bike traveling at 25 km/h has a braking distance of just 3 meters, but at higher speeds, it might take 7-8 meters to stop. Last year, my relative suffered a fracture from a fall after removing the speed limiter. If you really need speed, opt for a compliant electric motorcycle instead.

Honestly, don't even think about removing the speed limiter. Removing the speed limiter on a new national standard e-bike is equivalent to dismantling the entire safety system: the tires lack sufficient grip, the frame isn't rigid enough, and the braking system can't keep up. Manufacturers have embedded anti-tamper chips in the controller, and forcibly removing them will trigger error codes. Moreover, vehicles are inspected during registration now, and those with removed speed limiters won't pass the test. Traffic police across the country have been cracking down on modified vehicles recently—why take the risk? It's better to ride responsibly, ensuring both safety and peace of mind.

Specifically, the speed limit is controlled by the controller, but the new national standard requires manufacturers to implement physical anti-tampering measures. For example, some vehicles use special screws to secure the controller, which renders it useless if removed; others fill the circuit board with adhesive, making modification impossible. Even if modifications are possible, issues will arise with the speed sensor and motor matching—like a small horse pulling a heavy cart, which is particularly harmful to the battery. Once, I tried riding a bike with the speed limit removed, and even at slightly higher speeds, the handlebars felt unstable. If you're truly after speed, I recommend checking out the newly released high-speed electric bicycles, some models can reach 35 km/h while still complying with national standards.
