Can the speed of new national standard electric vehicles be modified?
2 Answers
It is possible to modify the speed, but it must not exceed 60 mph. Exceeding 60 mph would not comply with the new national standard for low-speed new energy electric vehicles. Below are some precautions for using electric vehicles: Regular charging: Generally, the battery starts discharging after leaving the factory. If left unused for one or two months, the battery will be completely drained. Over time, this will reduce battery performance and range. Therefore, even if not in use, the battery should be charged every half month to one month. Precautions: Many owners often forget to charge after use, leading to the necessity of using fast charging in emergencies. While one fast charge may not have a significant impact, frequent use can cause the battery to develop a bad memory effect, making it impossible to fully charge in the future, which affects travel and battery lifespan. Simply put, a regular battery can run 30 kilometers when fully charged, but fast charging may reduce this to just over 10 kilometers. Frequent use of fast charging can impact battery performance and shorten its lifespan.
I've talked to many e-bike users about this issue. New national standard e-bikes come with locked controllers from the factory, limiting speed to 25km/h at most. To go faster, you can flash the ECU or install a higher-power motor to bypass the speed limit. But I strongly advise against it! First, it clearly violates traffic laws—getting caught by traffic police could mean a fine of at least 500 yuan, and in serious cases, your vehicle might be impounded with penalty points. Second, safety is a major concern—the original braking system is designed for the speed limit, and modifying it increases braking distance, making sharp turns in the city or riding in the rain more prone to loss of control and crashes. In case of an accident, insurance companies may deny claims. If you really need higher speed, it's better to spend some money to switch to a compliant e-motorcycle or lightweight motorcycle—safer and worry-free.
