Owners of the popular model Xiaomi Mi Electric Scooter 1S often face an artificial maximum speed limit, which by default is 25 km / h. This is a standard requirement for compliance with European safety standards, but the technical characteristics of the engine and battery allow you to develop much higher rates. For many users, the question of how to remove the speed limit on the Xiaomi 1S electric scooter becomes a priority, since the regular mode is not always convenient for trips on flat roads or private areas.
There are several proven ways to bypass a software blocker, ranging from simple manipulation of an application to reflashing the controller. It is important to understand that any changes to the software can affect the warranty and safety of operation. In this article, we will detail legal and advanced methods of increasing the speed limit, assess the risks and provide step-by-step instructions for each technique.
Before you start any manipulation, you need to be aware of responsibility. Increased speed changes the dynamics of braking and stability of the design designed for less loads. Safety should remain the first priority, so all actions you perform at your own risk. We will look at both software methods through the mobile application and more complex options with the replacement of the firmware controller.
Technical features of speed limit in the 1S model
The Xiaomi Mi 1S is equipped with an updated controller compared to the first version, making the unlocking process more difficult but possible. The speed limit is sewn into the firmware of the device and controlled by the BMS (battery management system) and the main engine controller. The standard operating algorithm does not allow the motor to produce the power required to exceed 25-27 km / h, even if it is physically capable of doing so.
The main locking mechanism is to program the current cut off when a certain speed of rotation of the wheels is reached, the controller receives data from the Hall sensors and limits the power output, not only to comply with the laws, but also to extend the battery life and prevent overheating of the engine windings during long-term operation at limit modes.
⚠️ Attention: Removal of factory restrictions can lead to overheating of the engine with a long climb uphill and increase wear of the brake system, which is not designed to quench inertia from higher speeds.
It’s important for users to know that the 1S model has firmware protection over a standard Bluetooth interface, which means that simple methods that worked on older models may not work here without the use of specialized tools or paid services. The software is constantly updated by the manufacturer, closing vulnerabilities, so methods can change over time.
Software unlocking through the Xiaomi Home and Mi Home app
The easiest and safest way to get lost is to check the regional settings in the official app. Sometimes the speed limit on the Xiaomi 1S electric scooter is associated with the selected region in the Mi Home app. If the device was bought in Europe, it can have a hard software lock that can be removed by changing the region to China or the United States, where the limits are higher.
To perform this procedure, you need to completely remove the device from the application, reset the scooter settings and re-add it, selecting the “China” or “USA” region when registering. After that, the option of switching modes may appear in the settings menu or simply change the logic of the controller, allowing you to reach 30 km / h. However, on new firmware versions this method is often blocked.
If the region change didn’t help, you can try using third-party configurator apps like Xiaomi Scooter Hacking Utility (for Android).
- 📱 Smartphone with Android and enabled GPS/Bluetooth.
- 🔋 Charged electric scooter (preferably more than 50%).
- 📶 Stable Internet connection for uploading profiles.
- 🛠 Installed modification annex.
The connection process usually takes a few minutes. Once paired, the app will show the current firmware version and region. If your version of the software allows, you can change the region directly from the application, which will remove the speed limit. Region is a key factor in determining the maximum speed in the software code.
Using third-party software to change region and firmware
A more advanced method is to use specialized software to flash the controller. For the Xiaomi Mi 1S model, the Xiaomi Scooter Hacking Utility remains a popular tool. This application allows you not only to change the region, but also to install custom firmware that completely removes the speed limit or raises it to 35-40 km / h.
Before starting the procedure, it is critical to check whether your current firmware version is compatible with the hacker’s tool. If the version is too new, the application may offer a downgrade to an older version that has write vulnerabilities, a process that is risky and requires a stable connection.
Algorithm of actions when using the utility:
- Connect the scooter to the smartphone via Bluetooth.
- Launch the application and wait for the device definition.
- Check the “Dashboard” tab to analyze your current status.
- If available, select the option “Change Region” or “Install Custom Firmware”.
- Follow the instructions on the screen and do not interrupt the process.
⚠️ Warning: Interrupting the firmware process or losing a Bluetooth connection during data writing can lead to a “bricking” of the controller, after which the scooter will stop turning on.
Successful change of region or firmware allows you to unlock the potential of the engine. However, it is worth considering that custom firmware can turn off some safety functions, such as recovery at certain speeds or accurate temperature monitoring.
☑️ Pre-firmware check
Hardware Methods and Controller Replacement
If software methods fail or seem too risky, the hardware path remains: it consists in physically replacing the regular controller with a more powerful or modified counterpart that has no software restrictions. For the Xiaomi Mi 1S, there are controllers from third-party manufacturers that support speeds up to 45 km / h and above.
Replacing the controller is a complex technical procedure that requires electronics skills: you have to disassemble the scooter deck, disconnect a lot of wires, dismantle the old unit and install a new one. It is important to make sure that the new controller is compatible with your model's display and battery, or you may experience errors or the device will not work.
Comparison of the standard and modified controller:
| Characteristics | Staff controller | Modified/Tunned |
|---|---|---|
| Maximum speed | 25 km/h | 35-50 km/h |
| Dynamics of acceleration | Smooth, limited. | Sharp, tall. |
| Compatibility with software | Complete. | Possible display errors |
| Guarantee | It's still there. | Cancellation. |
| Cost | Included in price | Additional costs |
Once a new controller is installed, it often requires calibrating Hall sensors and checking all systems. Hardware modification is the most radical, but also the most efficient way to remove any software constraints forever.
Impact of unlocking on battery and safety
Increasing the top speed directly affects energy consumption: when driving at 35 km/h instead of 25 km/h, energy consumption increases exponentially due to air resistance, which means that the battery capacity will be consumed faster, and the real range can be reduced by 20-30%.
In addition, high discharge currents lead to heating of the batteries. The Xiaomi Mi 1S standard cooling system is passive and designed for standard loads. When driving aggressively at high speeds, especially in hot weather, BMS can overheat, which can lead to an emergency power outage or, in the worst case, to a fire.
How to extend the life of the battery after unlocking?
The brake system also suffers. Kinetic energy increases in proportion to the square of the speed. The standard brakes (electronic and mechanical drum/disc) may not be able to effectively brake at high speeds, especially on wet roads. The braking distance increases significantly, requiring the rider to be more distant and vigilant.
Legal aspects and operational recommendations
Before removing the speed limit, it is worth reading the legislation of your country. In many countries, including the Russian Federation and EU countries, driving an electric scooter at a speed above 25 km / h is equivalent to driving a moped, which requires the right to category “M” or “B”, registration of the vehicle and use of a helmet.
Driving on an unlocked scooter on public roads can result in fines or confiscation of the device by traffic police. Legislation strictly regulates technical means of individual mobility (SIM), and exceeding speed limits is a violation.
Recommendations for safe operation:
- 🛣 Use the increased speed only in closed areas or private areas.
- 🛡 Always wear protective gear: helmet, knee pads and gloves.
- 👀 Regularly check the condition of brake pads and tire pressure.
- 🔋 Control the battery temperature after long speed runs.
💡
After unlocking, it is recommended to immediately replace the standard brake pads with reinforced analogues with a better friction coefficient to ensure braking safety.
So unlocking the Xiaomi Mi 1S is a balance between the desired dynamics and potential risks.If you decide to take this step, choose proven methods and always remember about safety on the road.
💡
Removal of the speed limit is possible programmatically through a change of region or firmware, but this cancels the warranty and requires increased caution during operation due to increased loads on the scooter nodes.
