What is the tutorial for removing the speed limit of an electric vehicle?

Electric vehicle speed limit removal tutorial is: 1. Do not turn on the power, hold the brake handle, turn the speed control handle to the end, immediately turn on the power, while holding the brake handle, continuously turn the speed control handle to the maximum limit 3 times, and keep the speed control handle turned to the end for 5 to 8 seconds on the third time, the unlocking is successful; 2. In the state of turning off the power lock, hold the brake handle, turn the speed control handle to the end, then turn on the power lock, keep the speed control handle to the end and the brake for 3 to 5 seconds, and enter the full-speed state. Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and through components such as controllers and motors, convert electrical energy into mechanical energy movement, and control the speed by changing the current size.
Last time I researched this purely out of curiosity, I found that removing the speed limiter seems simple but is actually a huge pitfall. Pulling a wire or adjusting the controller might allow an e-bike to exceed 40 km/h, but the cost is high. The controller operating overloaded for long periods can burn the motherboard, and motor overheating can cause demagnetization, halving the range. Most critically, illegal modifications void insurance, meaning you're fully liable for any accidents. Once, I saw a neighbor crash into a green belt after their modified brakes failed—now I think it's better to just switch to a compliant electric motorcycle that can be legally registered. For real speed boosts, I recommend getting an official ECU tune at a licensed shop. It's pricier, but at least you won’t get your bike impounded by traffic police at night.
Stop messing with the speed limiter, buddy. I've tried three methods and none of them are reliable. Decoders can easily burn out the controller, software cracking requires specialized equipment, and physically cutting wires is even more dangerous. The key point is that the tires and braking system are designed for 25km/h. Forcing a higher speed will increase the braking distance by more than 2 meters. Last time I helped someone modify their bike and tested it, the body slid sideways when braking hard at 30km/h. I've learned my lesson now. If you really want speed, just buy a new national standard electric bicycle. Some models come with a sport mode that can reach 35km/h straight from the factory, at least the manufacturer has done safety tests.
As someone who frequently repairs electric vehicles, I must warn you: removing the speed limiter is equivalent to self-destructing the three-electric system. Overclocking the controller reduces its lifespan by three times, high-current discharge of 18650 batteries easily causes swelling, and the most critical issue is the high-temperature demagnetization of the motor's magnets. I've seen too many modified vehicles come back for repairs—the money saved on speed ends up being doubled on repairs. If you really want to optimize speed, consider these alternatives: check tire pressure weekly and maintain it at 2.8bar to reduce resistance, switch from lead-acid to lithium batteries to reduce weight by 20%, and perform regular brake system maintenance. These changes can safely increase speed by 5%.
