How to disperse a scooter Xiaomi M365 Pro to the maximum: legal and not very ways

Xiaomi electric scooter M365 The Pro is one of the most popular urban vehicles, but its factory speed limits (25 km/h) and acceleration dynamics often disappoint experienced riders. If you want to squeeze more power out of your "proshka" do not rush to buy a new model: With the right approach, you can increase the speed by 20-30% without critical damage to the battery and controller.

In this article, we'll look at all the possible ways to accelerate, from simple customizations in a mobile app to deep chip tuning and iron upgrades. It's important to understand that each method has its own risks. For example, remote speed limit firmware reduces battery life by 15-20 percent when you drive at the limit regularly, and replacing gears in the gearbox can lead to overheating of the engine. We will give clear recommendations on how to minimize negative consequences.

Before you start the modification, check the current condition of the scooter: tire wear, backlash in the bearings and battery level directly affect the final result. And remember: in most countries, acceleration above 25 km / h is equivalent to driving a moped - you will need M rights and a helmet.

1. Software methods: overclocking through firmware and application

The most affordable way to increase speed is to change the software constraints, and the manufacturer artificially lowers the maximums to meet European safety standards, and there are two ways to remove these restrictions:

• 📱 Official Mi Home app: In some regions (such as the US or China) speed limit is higher. +2-3 km/h.
• 🔧 Custom firmware: such as ScooterHacking Utility or Xiaoflasher allow you to disable the limiter completely, but require a PC connection.

For beginners, the first option is optimal. To change the region in Mi Home:

1. Open the application and go to Profile → Settings → Region.
2. Choose the United States or Singapore (the limit is 30 km/h).
3. Reconnect the scooter to the application and update the firmware through Device Settings → Update of the PO.

⚠️ Attention: After the change of region, the app will reset all saved routes and travel statistics, and the support of the Russian language in the scooter interface may also disappear.

For experienced users, firmware through ScooterHacking Utility will work.

• Cable USB-TTL (for example, FT232RL).
• ScooterHacking Utility (version at least 2.1)
• Remote Restricted Firmware File (see Xiaomi Today forums or WEB 4PDA).

Mechanical improvements: gears, wheels and suspension

If software overclocking doesn't work, it's time to look under the body. Mechanical modifications require tool skills, but they give you a more stable and safer speed gain.

Replacing gears in the gearbox is the most efficient upgrade. The standard pair of 16:40 (on the motor and wheel, respectively) limits maximum speed.

To replace the gears will require:

Remove the rear wheel and gearbox|Express old gears with a special renter|Install new gears with heatpaste|Check backlash and gaps|Lubricate the gearbox with Molykote lithium lubricant>

Installing larger-diameter wheels is another way to increase speed without interference with electronics. M365 Pros have a diameter of 8.5 inches. Replacement with 10-inch ones (for example, Kenda). K193) grant:

• 📏 Speed increase: +8-10 km / h at the same speed of the engine.
• ⚠️ Cons: decreases clearance, increases the load on the suspension.
• 🔧 Requires: New shock absorbers (e.g. Yume) D4+) and elongated mounting bolts.

⚠️ Wheels larger than 10 inches in diameter are not recommended for M365 Pro – this leads to overheating of the engine and reduce the battery life by 30-40%. Also check compatibility with the braking system: disc brakes may not cover the rim of the large wheel.

Modification of the battery: increased voltage and capacity

Xiaomi's standard battery M365 Pro has a voltage 36V and capacity 12,8Ah. Replacing it with a higher power boosts not only speed, but also range, but it's the riskiest upgrade, because a faulty connection can lead to a fire.

Modification options:

• 🔋 Replacement 48V Battery: increases speed by 25-30%, but requires a replacement controller (standard burns out after 1-2 trips). 48V 13Ah or LG 48V 15Ah.
• 🔄 Parallel connection of the second battery: doubles the capacity, but does not increase the voltage. The speed will not increase, but the range will reach 60-70 km.
• ⚡ Installation BMS High-current discharge: allows the battery to give more power at peak times (for example, during sharp acceleration). 36V system.

To replace the battery with 48V need:

1. Purchase a compatible controller (e.g. Votol) EM-150/48V).
2. Re-sweeten the power connectors of the motor and display (the connection scheme is available on GitHub ScooterHacking).
3. Configure current limit in new firmware (recommended value — 25A).

The budget option is to replace cells inside a standard battery, such as installing Samsung cells. 50E staff-up LG MJ1 It increases the capacity by 20 percent without changing the voltage:

1. Disassemble the battery body (you will need the thermophene to soften the glue).
2. Remove old cells while maintaining integrity BMS-pay-off.
3. Seal new elements while observing polarity and balancing.
4. Check the voltage at the terminals with a multimeter (should be 42.0) ± 0.5V).

Motor tuning: winding, magnets and cooling

The standard Xiaomi engine M365 Pro has power 300W (peak — 600W). It can be modified to increase returns, but it requires a deep knowledge of electrical engineering.

Methods of upgrading the engine:

• 🧲 Replacing magnets with neodymium: increases torque by 15–20%. Magnets are fine. N52 size 30×10×5 mm.
• 🔥 Rewinding: Reducing the number of turns increases maximum speeds, but reduces torque at low speeds.
• ❄️ Active cooling installation: the fan on the engine radiator allows you to keep the temperature below 60°C even under prolonged loads.

To rewind the engine with your own hands will require:

• Copper wire cross section 0.8-1.0 mm (length — ~50 meters).
• Epoxy resin for winding fixation.
• Multimeter for resistance testing (0.2–0.3 Ohms – normal).
• Thermal shrink tube for insulation.

⚠️ Warning: After rewinding the motor, be sure to check it idling for 10 minutes.°C, reduce the current in the firmware or install additional cooling. Also note that rewinding will void the warranty and may cause uneven wear of the gears.

The alternative is to replace the engine with a more powerful one, like Xiaomi's. M365 Pro 2 (350W) or Ninebot Max G30 (350W with better cooling) is placed without altering the fasteners:

• The speed will increase by 5-8 km / h.
• The power reserve will be reduced by 10-15% due to increased energy consumption.
• You will need to calibrate the controller via ScooterHacking Utility.

5. Weight optimization and aerodynamics

Reducing the weight of the scooter and improving its streamlining gives you an increase in speed by 3-5 km / h without interference with electronics, which is especially true for those who drive long distances.

How to lose weight:

• 🏋️ Replacement of the regular seat (if installed) with carbon fiber (savings — ~500g).
• 🔨 Removal of unnecessary fasteners (for example, for the trunk) - up to 300 g.
• 🔋 Replacement of the heavy battery housing with aluminum (minus 800-1000 g).

Aerodynamic improvements:

• 🚀 Installation of fairing on the front plug (for example, Aerox Fairing).
• 🪁 Replacement of wide handles with narrow carbon pens (reduces drag by 8-10%).
• 🛡️ Installation of a small windscreen (effective at speeds above 30 km/h).

Combine these methods to maximize effect, such as replacing the battery case. + carbon-plastic seat + The fairing will save 1.5 kg and improve aerodynamics by 12-15%, equivalent to a speed gain of 3-4 km/h with the same energy consumption.

💡

Before installing aerodynamic accessories, check that they are compatible with the folding mechanism of the scooter. Some fairings interfere with the folding of the steering wheel.

Alternative methods: trottle, pedals and external devices

If you are not ready to disassemble the scooter, there are several external modifications that will give an increase in speed or dynamics.

Installing an external trottle (e.g. Nanrobot Throttle) allows:

• 🎮 More precisely control acceleration (useful for sharp maneuvers).
• 🚀 Increase the maximum speed by 5-7 km/h by optimizing the gas supply.
• 🔄 Use regimes Eco/Turbo fly-by.

Connecting an external battery (powerbank) in parallel with the main battery gives:

• ⚡ Increase in range by 20-30 km (when used) 10Ah battery).
• 🔥 Ability to accelerate to 35-40 km / h (the risk of overheating of the controller!).

To connect an external battery:

1. Buy it. BMS-Balancing fee (for example, Daly) 6S 20A).
2. Connect the plus and minus terminals of the main and external batteries in parallel.
3. Set the safety on 30A sever.
4. Check the voltage with a multimeter - the difference between batteries should not exceed 0.5V.

⚠️ Note: Connecting an external battery without BMS Or with improper balancing leads to a fire situation, and note that such an upgrade will void the warranty and may cause problems when passing customs (if you are carrying a scooter in an airplane).

Safety after acceleration: brakes, tyres and protection

Increased speed of the scooter must be accompanied by an upgrade of the brake system and protection. M365 Pro designed for a maximum speed of 25 km / h - when accelerating to 35-40 km / h, the braking distance increases 2-3 times.

What needs updating:

• 🛑 Brake pads: replace with ceramic (for example, EBC FA69) — They can withstand heating to 600.°C.
• 🌀 Brake discs: perforated discs (e.g, ZOOM 140 mm) heat is better removed.
• 🛞 Tires: Install slicks with a hard cord (for example, Kenda) K1167) for better grip at high speeds.
• 🪖 Protection: wear a helmet (certified by the EN 1078), elbows and knee pads.

Additional security measures:

• 🔦 Install bright LED lights in front and back (e.g. Cateye Volt 300).
• 🔔 Use an audible signal (e.g., Hornit) DB140) pedestrian warning.
• 📱 Connect. GPS-Tracker (such as Tile Pro) in case of theft.

After dispersing the scooter, be sure to test it on a closed area:

1. Check the braking distance from 30 km/h (should be no more than 5 meters).
2. Make sure the scooter keeps the straight at maximum speed.
3. Check the heating of the motor and controller after 10 minutes of driving at high speed.

💡

Even after all the modifications Xiaomi M365 The Pro remains an urban scooter, not a race car. Don't go over 40 km/h, that's the safety limit for its design.

8 Legal aspects: what does the law say?

In most countries, electric scooters are equated to bicycles if their maximum speed does not exceed 25 km / h. M365 Pro automatically moves into the category of mopeds or scooters, which imposes additional obligations:

Requirements for scooters faster than 25 km / h (on the example of the Russian Federation, the EU, the USA):

Before dispersing the scooter, check local laws, for example, in Germany, scooters faster than 20 km / h require insurance, and in France - a special license plate.

• Insurance companies may refuse to pay in case of an accident if the scooter is modified.
• The police have the right to seize the scooter for examination if its speed exceeds the norm.
• In some countries (e.g. the UK) scooters faster than 15.5 mph (25 km/h) are generally banned on public roads.

If you plan to drive by the rules, but want a little more speed, consider installing a throttle with a limiter, for example, you can sew a scooter at 35 km / h, but physically limit the handle of gas to 28-30 km / h with a stopper, which will give a margin of power for overtaking, but will retain legal status.
