How to Remove the Speed Limit on Xinlei 48V
4 Answers
Locate the power switch of the Xinlei 48V and check if the power is on. Do not turn on the power. Hold the brake lever and turn the throttle to the maximum. Turn on the power while holding the brake lever and rotate the throttle to the maximum three times consecutively. On the third time, keep the throttle turned to the maximum for 5 to 8 seconds. The speed limit wire of the electric vehicle is generally located on the controller under the seat. Next to the controller, there is a single white power wire, which is a standalone wire. Cut this white wire. With the power lock off, hold the brake lever and turn the throttle to the maximum. Turn on the power lock, keep the throttle and brake engaged for 3-5 seconds to enter full-speed mode.
I understand that removing speed limiters is quite common. The default factory speed limit for Xinlei 48V electric bicycles is around 25 km/h, and some users find it too slow and want to increase the speed. In practice, this may involve working with the controller, such as locating and disconnecting the speed-limiting plug on the bike or using matching software to adjust parameters. However, it's important to remind you that modifying the speed limit privately violates traffic regulations. In many places, speeding can result in fines and vehicle impoundment, and it may also strain the braking system, leading to accidents, as well as faster tire wear. Manufacturers design speed limits with safety in mind, and modifying them means forfeiting the original warranty. If the motor burns out, you'll have to pay for repairs out of pocket, which isn’t worth it. If you really want to try, first back up the original settings and proceed with caution—don’t ignore the risks for temporary thrills.
I've encountered many people asking how to remove the speed limit on the Xinlei 48V, and actually, the method isn't difficult—you can figure it out by trying it yourself. Check the location of the vehicle's controller; there's usually a speed-limiting wire that's either white or black. Unplugging the connector might increase the speed. Alternatively, you can fine-tune the settings through the official app, but make sure to read the manual before operating to avoid mistakes. It's important to clarify that after removing the speed limit, battery consumption accelerates, and the full-charge range drops by about half. Additionally, riding at high speeds reduces the bike's stability, making it easier to crash. Not to mention the legal risks—if caught on the road, the bike could be impounded and fined, and the original factory insurance doesn't cover modified parts. It's best to weigh whether the extra speed is worth these risks.
My opinion on removing the speed limit of Xinlei 48V can be summed up in one sentence: Don't do it! The speed limit is a mandatory safety measure, and removing it poses significant risks. Speeding may cause the motor to overheat and burn out, and the tires may lose traction and skid, especially when riding fast in rainy weather, which can lead to loss of control and collisions with people or vehicles. Legally, this constitutes illegal modification, and if an accident occurs, you will be fully responsible for compensation and may face legal consequences. The vehicle is designed for commuting, with safety as the top priority. If you truly want to go faster, consider switching to a compliant high-speed model, which is both worry-free and safe.
