How to increase the speed of the Xiaomi electric scooter: from firmware to upgrade iron

Why is your Xiaomi moving slower than the factory?

You bought an electric scooter Xiaomi M365, Pro 2 or Essential, but after a couple of months, they noticed that the top speed had dropped from the stated 25-30 km / h to 20-22? Or does the scooter blunt when accelerating, "choking" on the rises, and the battery goes down too quickly? The reasons can be both software (firmware limitations, controller errors) and hardware (battery wear, mechanical pollution).

The manufacturer deliberately understates power in some regions due to local laws (e.g. the EU’s 25 km/h limit). But even without legal restrictions, the scooter loses momentum over time: lithium-ion batteries degrade, bearings get clogged with dirt, and the controller strangles the motor to save charge. In this article, we will examine legal and illegal methods of acceleration, from basic to extreme, with an assessment of risks and costs.

⚠️ Warning: Overclocking a Xiaomi scooter can lead to loss of warranty, overheating of the engine, battery fire or accident.All manipulations you perform at your own risk. Especially dangerous is exceeding the speed of 35 km / h is the limit of stability of most models.

1. Checking the current condition: diagnosis before acceleration

Before you try to speed up the scooter, make sure it's working.

Measure the real speed through GPS (Strava applications or GPS Speedometer>)

Check the battery voltage in Settings → On the scooter (must be) ≥42V on full charge)

Examine the wheels for tread wear and pressure (normal: 2.5-3.0 bar)

Test the brakes – they shouldn’t block the wheel abruptly (the risk of a coup)

Listen to the motor for extraneous noise (squeaking, crackling, vibration)

-->

If the scooter does not accelerate above 15-18 km / h, the problem may be:

• 🔋 Discharged battery (voltage below 36 V)
• 🛠️ Contaminated controller (dust, moisture, oxidation of contacts)
• 🚲 Worn bearings (backlash in the wheel, noise during rotation)
• 📱 Firmware restrictions (regional speed limit)

For accurate diagnosis, use the Xiaomi Home app or M365 DownG (shows controller errors in real time) error codes:

Xiaomi Essential

Xiaomi 3/4 Lite

2. Software overclocking: changing firmware and settings

The most affordable way to increase speed is to roll back or modify the firmware. The manufacturer often releases power-limiting updates for safety or compliance. M365 Maximum speed reduced to 20 km/h for the EU.

To accelerate through the firmware you will need:

• 💻 Computer with Windows/macOS
• 🔌 USB-Type-C Cable (Original)
• 📥 DownG or ScooterHacking Utility
• 🔧 Firmware with a patch (e.g, CFW 1.6.1 Unlocked)

Step-by-step:

1. Download the archive with the firmware and DownG program from the official GitHub repository.
2. Connect the scooter to the PC by holding the power button for 5 seconds (firmware mode).
3. Run DownG, select a firmware file (for example, BMS_1.6.1_mod.bin).
4. Press Flash and wait until it is completed (don’t turn off the scooter!).

⚠️ Note: Some of the firmware is disconnected KERS (Regenerative braking, which reduces battery life, and after firmware, check the brakes, they may become less responsive.

3. Hardware tuning: replacement of gear and motor

If the software acceleration gave an increase of only 1-2 km / h, it is time to consider the upgrade of iron.

• 🔄 Replacement of gear (from 1:16 to 1:14 or 1:12) - increases speed by 5-8 km / h, but reduces thrust.
• ⚡ Installation of the engine 500W+ (For example, from Xiaomi Pro 2 on M365) — It increases 3-5 km / h and improves acceleration.
• 🔋 Battery upgrade (replacement of cells on Samsung) 50E or LG MJ1) — Increases voltage to 48–52V.

Example: Replacement of gears on Xiaomi M365 1:16 to 1:12 gives:

⚠️ Note: After replacing the gear, be sure to update the controller’s firmware, otherwise it will give an error. 21 (parameter mismatch. M365 firmware DRV132_mod.

💡

Apply heat-resistant lubrication (such as the Molykote G-Rapid Plus) to the gear before replacing it, which will reduce wear and noise by 30-40%.

4. Battery Optimization: How to Get Back Power

The battery is Xiaomi's weakest point, and after 200 to 300 charging cycles, it drops 20 to 30 percent in capacity, which directly affects speed. Here's how to restore performance:

• 🔌 Battery calibration: discharge the scooter to 0%, then charge to 100% without interruption. Repeat 2-3 times.
• ⚡ Replacement BMS-If the scooter suddenly shuts down at 30-40% charge, the battery controller is to blame (cost of replacement: ~1500 ₽).
• 🔋 Repackaging cells: replacing old elements with new Samsung 50E Increases capacity from 7800 mAh to 10,000 mAh.

How to check the status of the battery:

1. Install the app M365 Tools (Android) or ScooterStats (iOS).
2. Connect to the scooter via Bluetooth.
3. Look at the Cell Voltage settings. 0.1V speaks of degradation.

⚠️ Note: If the cell voltage is lower 3.0V, It can't be charged with standard RAM -- you can't explode! Use a balancing device like an iMax. B6).

💡

Replacing the battery cells with Samsung 50E Not only does it increase speed by 2-3 km/h, it also extends the range by 30-40%, but it requires soldering and knowledge of circuitry - it is better to trust the specialists.

5. Small improvements with great effect

You don't always have to go into the firmware or disassemble the scooter, and sometimes it's just a little bit of a change to make things better.

• 🚴 Tyre pressure: Increase to 3.0-3.5 bar (reduce rolling resistance).
• 🛑 Shutdown KERS in settings (if there is an option) - will add 1-2 km / h.
• 🧲 Removal of magnets from brake disc (reduces parasitic braking).
• 🛠️ Bearing lubricant (use it) WD-40 Specialist for high loads).

Example: On the Xiaomi Pro 2, increasing tire pressure from 2.0 to 3.2 bar gives:

• ✅ Speed increase: +1.5 km/h
• ✅ Improved coast-course: +10–15%
• ❌ Deterioration of comfort (hard driving)

⚠️ Warning: If you remove the magnets from the brake disc, the electric brakes will fail.

6. Extreme tuning: risks and consequences

Some owners go further and modify the scooter to 40-50 km / h. This is achieved:

• 🔥 Installation of the controller 72V (For example, from Dualtron).
• ⚡ Connecting two batteries in parallel (increased voltage to the 84V).
• 🚀 Replacement of the motor with a brushless 1000W+.

Consequences of such tuning:

⚠️ Note: Xiaomi scooters are not designed for speeds above 35 km / h:

• The frame can break on the bumps (aluminum can not withstand the load).
• The braking distance increases to 10-15 meters (risk of accident).
• The battery overheats, which leads to thermal acceleration (fire).

💡

If you still decide on extreme tuning, install an additional radiator on the controller and use the Arctic thermal paste. MX-6. This will reduce the risk of overheating by 20-25%.

7 Legal aspects: what does the law say?

In Russia and most EU countries, electric scooters are equated to pedestrians or bicycles, but with restrictions:

• 📜 Maximum speed: 25 km/h (in the EU), 20 km/h (in some regions of the Russian Federation).
• 🚦 Road traffic: prohibited (only bike lanes or pavement).
• 👮 Fines: from 1,000 ₽ for speeding up to 5,000 ₽ driveway.

In 2023, a bill was adopted in Russia that tightens the requirements for electric scooters:

⚠️ Note: From January 1, 2026, scooters with capacity >250W are subject to mandatory registration in the traffic police. Also required insurance (OSAGO) and driving license category "Ministry of the road».

If you are stopped on an overclocked scooter, the inspector may:

• 📋 Expense a speeding ticket (similar to a car).
• 🚔 Confiscate the scooter for examination (if the modifications are not certified).
• 📄 Make a protocol for the control of a faulty vehicle (if the brakes or magnets are removed).
