How to remove the rear wheel on Xiaomi M365 Pro 2: disassembly without errors

Xiaomi's electric scooters are some of the most laden parts in the rear. In the M365 Pro 2, they not only provide propulsion, but also integrate with the brake system and the electric motor. Over time, the wheel may need to be replaced due to rubber wear, rim damage, or engine failure, but improper dismantling can damage the wiring, bearings, or even the controller.

In this article, we're going to take a step-by-step rear wheel removal algorithm that takes into account the features of the M365 Pro 2, including hidden nuances that are not mentioned in the standard instructions. We're going to look at the tools, the sequence of actions, and the typical errors that can cause the scooter to fail. If you've never disassembled an electric vehicle, don't worry: the process is simpler than it seems, but requires precision.

⚠️ Warning: Before starting work, completely discharge the battery (up to 0.5%) to minimize the risk of short circuits in case of accidental damage to the wiring of the motor. M365 Pro 2 uses a high-voltage system (36V), which can disable the controller in case of careless handling.

1.Preparation: tools and conditions for work

You won’t need professional equipment to dismantle the rear wheel of the Xiaomi M365 Pro 2, but the lack of at least one tool can complicate the process.

• 🔧 End key 14 mm (or head with a collar) - for unscrewing the axis nuts.
• 🔧 Hexagon by 5 mm - for fixing the brake disc.
• 🔧 Flat screwdriver (with a wide sting) - for putting the engine cover on.
• 🔧 Flat-slippers - can be useful for removing locking rings.
• 🧴 WD-40 Or similar lubrication – if the nuts are boiled.
• 📦 Plastic screeds or scotch - for fixing wires.

Also prepare the workplace:

• 📏 Smooth surface (table or floor with substrate).
• 💡 Good lighting – details are small, easy to lose.
• 📱 Phone to shoot – take pictures of each step so as not to confuse the order of the assembly.

⚠️ Warning: If the scooter was used in rainy weather, dry it for 12-24 hours before disassembly. Humidity inside the wheel can cause corrosion of motor contacts after assembly.

Power and braking system disconnection

The first critical step is to turn off the scooter. In the M365 Pro 2, power is supplied to the engine even when the battery is switched off.

1. Turn off the scooter with the power button.
2. Unplug the battery: unscrew the 4 screws on the bottom lid (under your feet) and gently disconnect the battery connector from the controller. Don't pull the wires - just behind the plastic housing of the connector!
3. Remove the brake pads: they are attached with two bolts by 5 mm (hex-sided). Put them aside so as not to lose them.

🔹 Why can't we ignore the battery shutdown? M365 The Pro 2 controller can send pulse signals to the motor even when it's off:

• 🔥 Overheating of motor windings in case of accidental closure.
• 💥 Damage to the power board (the cost of repair is up to 50% of the price of the scooter).

💡

If the axle nuts don't lend themselves, don't use excessive force - wet them with WD-40 and wait 10-15 minutes. The M365 Pro 2 often uses nuts with a fixing compound that hardens over time.

Dismantling of the wheel: step-by-step instructions

Now, to the basic process, follow the algorithm in strict order.

1. Remove the plastic motor cover: Tuck it in with a flat screwdriver on both sides (carefully so as not to break the latches). Disconnect the Hall sensor connector (a small white connector).
2. Unscrew the axis nuts: Use the end key 14 mm. Not all the way! First, loosen the nuts, then unscrew them completely. Hold the wheel with your hand, it can jump off the axis dramatically.
3. Remove the wheel from the axle: Pull it on yourself, while swaying from side to side. If the wheel is jammed, check if there are any locking rings left (they need to be removed with pliers).

📌 Important point: In M365 The Pro 2 wheel axle has asymmetrical threads -- right and left nuts twist in different directions.

4.Working with wiring and sensors: what can not be damaged

The most vulnerable part of dismantling is the motor wiring and the Hall sensor, which in the M365 Pro 2 are integrated into the wheel and can come off if handled carelessly.

• 🔌 Don't pull the wires - just the connectors.
• 📏 Lock the wires with screeds so they don't hang around and cling to details.
• 🔍 Check the integrity of the insulation – if it cracks, replace it with a shrink tube.

🔹 What is a Hall sensor and why is it important?

This is a little sensor that detects the position of the motor rotor, and if it's damaged, it's a scooter.

• 🛑 It will not be easy to move (at the start).
• ⚡ Consumes more energy (reduced range of power).
• 🔊 emits extraneous sounds (screaming or vibration).

⚠️ Warning: If you're taking off a motor replacement wheel, don't buy cheap ones without a Hall sensor. They're incompatible with the controller. M365 Pro 2 and will burn within a month.

5. Common Mistakes and How to Avoid Them

Even experienced users make mistakes when disassembling the Xiaomi M365 Pro 2.

🔧 Advice from the masters: If you remove the wheel to replace the tire, do not use mounting blades - they will damage the rim. M365 Pro 2 is better to use the method of "heating": place the wheel in warm water (40-50).°C) for 10 minutes - the rubber will become more elastic and will be removed without effort.

6. Wheel assembly: reverse sequence and nuances

And assembly isn't just a reverse disassembly process, it's got its tricks.

1. Apply the lubricant to the axle (use lithium lubricant or bearing lubricant).
2. Install the wheel on the axle, combining the holes for the brake disc.
3. Tighten the nuts cross-cross (first left, then right) to avoid skewing.
4. Connect the Hall sensor connector, and it's going to click.
5. Check the brakes: scroll the wheel manually - it should rotate freely, without touching the pads.

⚠️ Warning: Don't get on the scooter right away after assembly:

1. Put the battery on.
2. Turn on the scooter and check if there are any errors on the display (code E02 is a problem with the engine, E03 is a brake sensor).
3. Test the brakes and acceleration on a flat surface.

💡

If the scooter twitches at launch after assembly, it's likely that the Hall sensor is not connected correctly.

7.When to contact the service: signs of serious malfunctions

Not all problems with the rear wheel of the Xiaomi M365 Pro 2 can be solved by yourself.

• 🔥 Motor's warming to 70.°C and above (norm to 50)°C).
• ⚡ Scooter is not going, but the display shows speed (power board problem).
• 🔊 A metal grinding is heard - bearings or rotor may break.
• 💧 Water gets into the wheel (even after drying, it may be necessary to replace the engine).

💰 Cost of repairs in the service:

🔹 Tip: If the scooter is warranty, do not disassemble it yourself - opening the wheel will cancel the warranty on the motor and controller.
