How to increase the speed of the Xiaomi 1S scooter: effective ways to accelerate

Owners of the popular model Xiaomi Mi Electric Scooter 1S often face a software limit of maximum speed, which in standard firmware is only 25 km / h This restriction is dictated by the legislation of many countries, but technically the device is able to develop a much higher speed, sometimes up to 30-35 km / h, which is especially important for safe overtaking on wide roads or when driving against strong winds.

In order to unlock the potential of your vehicle, you need to intervene in the operation of the controller software or change the settings of the region in the Mi Home application. It is important to understand that any manipulation of the firmware carries certain risks, but with a competent approach and compliance with safety precautions, the procedure is successful and opens up new management opportunities.

In this article, we will take a look at proven speeding techniques, look at the tools you need, and warn against common errors that can lead to a device locking. Software modification is a delicate process that requires attention, but the result is worth it for those who want to make the most of their gadget.

Analysis of factory constraints and technical potential

The factory configuration of the controller in the 1S model severely limits the voltage to the engine when a certain speed is reached. This software "strangulation" is implemented at the firmware level, so simply replacing the battery or wheels will not give the desired effect without changing the code.

Technically, the electric motor in this model has enough safety margin to operate at higher revs. However, the BMS (Battery Management System) system also has its own current output limits, which must be considered so as not to cause overheating or emergency battery shutdown.

⚠️ Attention: Removing speed limits may cause accelerated wear of bearings, tires and reduced overall battery life.

There are several levels of intervention, from simply changing the region of the application, which is the safest method, to completely flashing the controller through special utilities, the choice of method depends on your current version of the software and the desired result.

The method of changing the region in the application Mi Home

The easiest and most affordable way to do this is to change the region in the Mi Home settings. The manufacturer's logic is simple: different countries have different laws, and for markets where the 25 km/h limit is not relevant, unlocking is built-in by default.

To implement this method, you need to have a Xiaomi account. After you log in, go to your profile and change region to China or the United States. In some cases, you need to completely remove the device from the list and re-pair after changing the region.

After a region change, the scooter may require a firmware update. If an update is offered, agree, as the new version may contain modified speed controller algorithms.

• 🌍 Change the region in the Mi Home profile to China or the United States.
• 🔄 Remove the scooter from the list of devices and perform re-pairing.
• 📲 Check for firmware updates in the new region.
• ⚡ Test the maximum speed on a safe section of the road.

It's worth noting that this is reversible, and if you don't like the result or have problems with connection stability, you can always go back to the original region and reset the settings.

Software unlocking via PC and Xiaomi Flash

A more advanced method that gives guaranteed results is to flash the controller using a computer and a special cable. For the 1S model, Xiaomi Flasher utility or specialized scripts running through the BLE (Bluetooth Low Energy) protocol are often used.

You’ll need a Windows laptop, installed drivers for the Bluetooth adapter, and the cable itself to connect (sometimes you need a deck disassembly to access contacts if the wireless connection isn’t working), the process is to load the modified firmware file and fill it into the controller’s memory.

python flash_tool.py --device 1S --firmware custom_unlocked.bin --region EU

It is critical to find the right firmware version that matches your hardware auditor, and the wrong software can lock the controller, turning the scooter into a brick that requires expensive repairs at the service center.

After successful firmware, the scooter needs to be restarted. Usually, the speed indicator on the display will begin to show real values above the standard 25 km / h. In some cases, it may be necessary to calibrate the gyroscope through the application.

Installation of custom software and alternative controllers

For those who want to gain full control of the device, custom software like the M365 DownG or BleScanner can be installed, not only to remove the speed limit, but also to adjust the acceleration curve, recovery and other parameters.

An alternative to software tuning is to physically replace the controller with a more powerful third-party counterpart, a hardware upgrade that not only increases speed but also improves acceleration dynamics, although it requires electronics skills.

Using third-party software opens access to hidden menus where you can turn off sound signals, change the brightness of the display and even activate modes that are initially unavailable in the basic configuration.

The impact of tuning on battery and safety

Speed increases have a direct impact on energy consumption, and when you're driving at top speed, your energy consumption increases exponentially because of air resistance, which means that the range on a single charge can be reduced by a single charge. 20-30%.

The engine and controller are running at their limits, which can lead to overheating during long climbs or aggressive driving, and the thermal protection system can force the power to decrease if the sensors detect critical temperatures.

💡

To minimize the risks of overheating after acceleration, it is recommended (regularly check) the temperature of the motor wheel with your hand after long trips and allow the device to cool down.

⚠️ Warning: Modified scooter loses factory warranty, and in case of breakdown, official service centers may refuse free repairs if they find a modified firmware.

It is recommended to regularly monitor the voltage of the battery cells through diagnostic utilities, since uneven acceleration can more quickly disable individual battery assembly elements.

Checking the result and diagnosis

After you've done all the manipulations, you need to make sure that the operation is successful. GPS-Tracker or Navigator in a Smartphone to Avoid Error.

Pay attention to the behavior of the brakes. At higher speeds, regular brake mechanisms may be less effective, so it is recommended to check their performance in advance and, if necessary, tighten the cables or replace the pads.

If you notice unstable work, jerks during acceleration or spontaneous shutdown, immediately return the factory firmware. 2-3 km/h.
