Xiaomi electric scooter M365 It's a legend in urban transport, it's reliable, it's compact, but it's got one big downside: 25 km/h factory speeds don't seem good enough for many people, especially when 30 scooters are coming by.+ Good news: speed. M365 It can be increased in one way or another.
The bad news is that not all methods are equally safe. Incorrect overclocking can shorten battery life, overheat the controller, or even cause an emergency shutdown while driving. In this article, we’ll look at 8 proven ways to increase speed, from simple settings to deep iron upgrades, with a focus on balancing performance and reliability.
It's important to understand that overclocking is always risky. If you're a beginner, start with software methods (firmware, application settings). Hardware modifications will suit advanced users. And for those who are willing to go further, we'll tell you how to turn it into a new product. M365 c full-fledged high-speed scooter with indicators of 35 km / h and above.
1. Unlock speed through the official Mi Home app
The easiest and safest way is to use the branded Mi Home app. the manufacturer put Xiaomi in the firmware M365 the possibility of temporarily increasing the speed to 30 km / h, but by default it is disabled.
To activate the mode:
- Connect the scooter to the application via Bluetooth.
- Go to the Settings section → Driving mode.
- Select the option “Sport Mode” (or Sport Mode in English).
- Save the changes and restart the scooter (turn off/turn on power).
⚠️ Note: This scooter will consume 20-25% More energy and more braking distance, and it's not recommended to use Sport Mode when driving on wet roads or in poor visibility.
Cons of the method:
- 🔋 Fast battery discharge (autonomy is reduced with 30 before 22-24 km).
- 🛑 Increased wear of brake pads.
- ⚠️ Risk of Controller locking when overheating (if driving for longer than 20 minutes in a row).
2. firmware custom software: up to 32 km / h without upgrading iron
The official speed limits are in the controller's firmware, replacing it with custom (e.g. ScooterHacking Utility or DownG). CFW), You can unlock the engine potential to 30-32 km/h without physical changes.
Step-by-step:
- Download the ScooterHacking Utility (supports) Windows/macOS/Linux).
- Connect the scooter to the PC via a USB-Type-C cable (use the original cord from Xiaomi).
- Launch the utility and select a model M365.
- From the Firmware menu, select the firmware version marked “Unlocked Speed”.
- Click Flash Firmware and wait until it is completed (the process will take place). 3-5 minute).
⚠️ Attention: Continuous use of custom firmware can overheat the controller (especially in the heat). 2-3 month.
The advantages of custom firmware:
- 🚀 Speed up to 32 km / h (depending on the software version).
- 🔧 Additional settings: Disabling cruise control, changing the response of the throttle.
- 📊 Ability to roll back changes at any time.
Cons:
- ⚡ Reduced battery life by 15-20%.
- 🔌 Risk of "brick" with interrupted firmware (if power is turned off).
- ❌ Loss of warranty (if scooter is guaranteed).

Replacement of the gear of the motor: mechanical acceleration to 35 km/h
If the software isn't working, it's time to upgrade to the iron, and one of the most effective ways is to replace the gear with a version with fewer teeth, which increases gear ratio and, as a result, speed.
For Xiaomi. M365 fitting gears from models M365 Pro or Ninebot Max with 36 teeth (instead of standard teeth) 42). After the replacement, the speed will increase. 33-35 mileage, but there are nuances:
- 🔧 Requires disassembly of the engine (requires experience or help from the service center).
- 💪 Increased load on the battery and controller.
- 🛑 The braking distance is getting longer by 30-40%.
Cost of gear: 1,500–2,500 ₽ (It's 1,000 to 1,500 times the service cost. ₽.
| Parameter | Stock gear (42 teeth) | Modified (36 teeth) |
|---|---|---|
| Max, speed. | 25 km/h | 33-35 km/h |
| Acceleration to 25 km/h | 6-7 seconds | 4-5 sack |
| Braking distance (from 25 km/h) | 3.5 m | 4,5-5? |
| Battery resource | 300-400 cycles | 250-300 cycle |
⚠️ Warning: After changing the gear, be sure to check the tension of the belt. Weak tension will lead to slippage, and too strong will lead to accelerated wear of the bearings.
What happens if you put a gear with 32 teeth?
Installation of a high-capacity battery (48V → 52V)
Xiaomi's standard battery M365 tension 36V (10S). Replace him with a version 48V (13S) or 52V (14S) increases not only the range, but also the maximum speed of the 15-20%.
Causes of speed increase:
- 🔋 Higher voltage = motor-power.
- 🚀 Improved acceleration dynamics (especially noticeable on the climbs).
- 🔄 The ability to use firmware optimized for 48V/52V.
The best battery options for upgrades:
- 🔋 13S (48V) 15Ah — speed 30 km/h, range 40-45 km.
- 🔋 14S (52V) 18Ah — speed 35 km/h, range 50-55 km.
- 🔋 13S (48V) 20Ah s BMS — Optimal balance of price/quality.
⚠️ Warning: When replacing the battery, be sure to update the controller firmware to the new voltage! 52V-Batteries with stock software will cause instantaneous combustion of the controller.
Upgrade cost:
- Battery 48V/15Ah: 8 000–12 000 ₽.
- Battery 52V/18Ah: 15 000–20 000 ₽.
- Firmware for high-voltage battery: free (if you do it yourself) or 1000–2000 ₽ (service).
💡
Before buying a battery, check it is compatible with your controller! some models require replacement BMS-charge-up.
5. Modification of the controller: firmware for high currents
Xiaomi Stock Controller M365 level-bound 12-15What's holding back the power of the motor, the firmware of the controller to high currents (20-25(a) allows:
- 🚀 Increase speed to 30-35 km/h (coupled with battery upgrades).
- 💨 Improve the acceleration (especially on the climbs).
- 🔧 Turn off temperature restrictions (risky!).
You'll need firmware.
- ST-Link programmer V2 (~500 ₽).
- Cable to connect to the controller.
- Firmware from the EScooterica forum (for example, M365_25A_Unlocked.bin).
⚠️ Note: Controller firmware for currents above 20A requires:
- Extended cooling (an additional radiator can be installed).
- Regular temperature control (via Bluetooth module).
- Replacement of power keys ( MOSFET ) currents above 25A.
Risks:
- ⚡ Overheating and Controller failure.
- 🔥 Fire with a short circuit (if you do not properly weld the wires).
- ❌ Total loss of warranty.
💡
High-current controller firmware gives you the maximum speed gain, but it's the riskiest method, and is recommended only for advanced users with access to soldering equipment.
6.Tyre pressure optimization and weight reduction
Sometimes even small improvements can give you a noticeable increase in speed.
Increase in tyre pressure
- 🚲 Optimum pressure for M365: 3,5-4,0 bar — 2,5 bar).
- 📈 Speed increase: 1-2 km/h (by reducing rolling resistance).
- ⚠️ Do not exceed 4.5 bar - the risk of tearing the tire!
2. Weight loss of the scooter
- 🏋️ Replacement of the regular seat with carbon fiber (savings) ~300g).
- 🔋 Removal of unnecessary accessories (lights, trunk).
- 🛠️ Replacing metal bolts with titanium (savings) ~200g).
These methods will not give such an increase as firmware or upgrade of iron, but they are absolutely safe and do not require investment.
7.Alternative methods: throttle tuning and cruise control
If you do not need a constant high speed, but want to accelerate faster - modify the throttle (gas).
Ways:
- 🎮 Replacement of throttle with hall-sensor (analog instead of digital) – smooth acceleration without delay.
- 🔧 Setting sensitivity through firmware (Throttle Response parameter).
- 🚀 Install a turbo button (momentary switch) for instant acceleration.
You can also turn off cruise control (if it interferes):
- Open Mi Home.
- Go to Settings. → Cruise control.
- Turn off the option or reduce the activation time to 0 seconds.
8.Verified life hacks for safety during acceleration
Speed increases are always associated with risks, to minimize them:
Mandatory improvements:
- 🛡️ Installation of disc brakes (replacement of the regular drum brakes).
- 🔦 Lighting upgrades (LED-headlights + extra dimensions).
- 📱 Installation of Bluetooth module for monitoring the temperature of the controller.
Rules of driving:
- 🚦 Do not accelerate above 30 km / h in urban conditions.
- 👟 Use protective equipment (helmets, elbow pads, knee pads).
- 🔋 Watch the level of charge - at a discharge below 20%, the speed drops sharply.
⚠️ Attention: At speeds above 30 km/h, Xiaomi brake distance M365 It's over 6 meters (even with disc brakes!
