Electric scooters Xiaomi M365 Pro have proven to be a reliable means of transportation, but intensive operation inevitably leads to wear of parts. Most often suffers the rear wheel, which is both a driving element and part of the electric drive. The puncture of the camera or wear of the tire is not a reason for panic, but the situation requires competent technical intervention.
Many owners are afraid to disassemble the motor wheel for fear of damaging thin wires or disrupting the tightness of the system. Indeed, Xiaomi design requires accuracy, but with the right tool and knowledge, the replacement process becomes quite feasible at home.
In this article, we will take a detailed look at each step of dismantling, explain how to disconnect the electrical contacts and remove the tire from the disk without special machines. You will learn about the nuances of working with lock rings and the correct assembly procedure, which will save you time and money on maintenance.
Tools and workplace preparation required
Before any repair work begins, the Xiaomi Mijia Electric Scooter needs to prepare the workspace, you need a flat surface, sufficient lighting and a set of specific tools that are not always in a standard home medicine cabinet.
The main tool for working with fasteners will be a set of hexagons (usually metric sizes). Also critical is the presence of a stop ring removable, since regular passages will not help here. To work with the tire, you will need two mounting blades, preferably made of durable plastic or metal with rubberized edges.
Here is a complete list of what to have on hand before the showdown begins:
- 🛠️ Set of hexagonal keys (including 8 mm for the axis)
- 🔧 Special Remover for Lock Rings (Internal Capture)
- 💨 compressor or pump for pumping tires after assembly
- 🧤 Protective gloves and rags to remove old lubricant
- 📏 Flat screwdriver for neat tweaking of elements
Pay special attention to the screwdriver: you'll need it to work with the contact group, make sure that its sting is the exact size so as not to damage the insulation of the wires inside the motor, and it takes less time to prepare the tool than to find the missing part in the middle of the process.
⚠️ Attention! Before starting work, be sure to completely disable the scooter. Press the power button 5 times in a row, then another 5 times to make sure there is no voltage in the system.
☑️ Preparations for dismantling
Dismantling the wheel from the frame of the electric scooter
The removal process starts with the wheel being separated from the pendulum, which requires you to flip the scooter or securely lock it upright, and the first step is always to remove the brake disc if it interferes with access, but in the M365 Pro, we first release the axle mounts.
Using an 8mm key, unscrew the nuts that hold the wheel axis. Notice the washers and the spacers: their order is important when you reverse assemble them. Once the mounts are loose, the wheel will not fall off itself, because it is fixed by electrical wires going into the frame.
Carefully pull the axle and remove the wheel from the seat. Now you have to unplug the engine cable. The connector is inside the frame, next to the controller. Be very careful: Xiaomi's plastic connector locks are quite fragile and easily break when handled carelessly.
To remove the wire, you often need to remove the side cover of the deck. Unscrew all the visible screws around the perimeter and gently click the clips. The motor wire has a specific connector that you need to unlock by moving the lock, and only then pull on yourself.
💡
When removing the wheel, put a soft cloth or cardboard under it so as not to scratch the rim and brake disc on the concrete floor or tile.
Disassembly of the motor-wheel and removal of the stop ring
The most difficult step is to disassemble the wheel itself to replace the camera or tire, and unlike conventional bicycle wheels, there are no spokes, and the tire is held on the rim by pressure and a special locking ring, which prevents the tire from turning against the disc when abruptly starting or braking.
First, you have to completely flush the air out of the chamber, and then you use two mounting blades to squeeze the tyre side into the disc to release the locking ring, and it takes physical effort, and you go around and move gradually until you have access to the ring groove.
It is important not to damage the motor winding, which is very close to the inside of the rim. Any scratch on the winding varnish may cause the turn-to-turn circuit in the future. Use the removable carefully, controlling the depth of the instrument's immersion.
When the ring is shown from under the tire, grab it with the removable and pull it out in a circle. Once the stopper is removed, the tire can be removed from the disc. Often it clings or sits tightly on the rim, so it may require the use of force, but without fanaticism, so as not to deform the disk.
⚠️ Never use sharp metal objects (knives, screwdrivers) to pick inside the wheel.You can easily cut through the insulation of the motor winding, making repairs economically inefficient.

Comparison of original and analog tires
When replacing consumables, owners often face a choice between buying expensive original rubber or a more affordable one. Understanding the difference will help make an informed decision. Xiaomi’s original tires have a specific rubber composition, but their resource does not always justify the high price.
Chinese rubber can be tougher or softer than the original. Hard rubber holds punctures better, but transmits more vibration to the frame. Soft rubber is more comfortable, but wears faster. Below is a table to help you decide on your choice.
| Characteristics | Original Xiaomi | Quality analogue | Budgetary option |
|---|---|---|---|
| Wear resistance | Tall. | Medium | Low. |
| Clutch to the road | Excellent. | Good. | Mediocre |
| Price. | Tall. | Medium | Low. |
| Risk of puncture | Medium. | Depends on the model. | High-pitched |
Some users are switching to tubeless kits or cast wheels to forget about punctures forever. However, cast wheels are significantly stiffer and can adversely affect the bearings and frame of the scooter when driving on bad roads. The choice is yours, but the classic camera remains the gold standard of comfort.
Wheel assembly and installation of new components
The assembly is done in reverse order, but it has its own technical nuances: the new camera needs to be slightly pumped before installation, so that it does not get pinched between the rim and the tire, which is a critical point that affects the life of the new camera.
Put the tire on the disc, making sure that the nipple is straight in its hole, without skewing. Then insert the locking ring into the groove. This is the most time-consuming part: the ring should be evenly distributed around the circle. Use the filmmaker or carefully poke it with a screwdriver, making sure that it does not pop out.
Once you have the ring, check if the tire is sitting exactly around the circle. There's often a marking line on the sidewall; it has to run parallel to the rim. If the line is walking, then the tire is crooked and needs to be corrected by flushing the air.
The final step is pumping. Bring the pressure to the recommended values (usually 3.5-4.5 atmosphere for the Xiaomi M365 Pro). Check the leakproofness with soap solution: there should be no bubbles. Only then can the wheel be installed back on the frame.
⚠️ Attention! When assembly, make sure that the motor wire is not twisted or clamped between parts of the wheel, and when rotating, it can be worn over, which will short-circuit and the controller will fail.
💡
Proper installation of the locking ring is a guarantee that the tire will not turn when braking sharply, which is especially important for powerful versions of the Pro.
Frequent errors and troubleshooting
Even experienced craftsmen can make the mistake of first learning about the design of an electric scooter, and one of the most common problems is the beat of the wheel after assembly, which occurs when the locking ring is not in its groove or the tire is uneven.
Another common mistake is the pulling of the axle nuts, which can cause the seats in the pendulum to deform or make it difficult for the bearings to rotate, use a dynamometer key or rely on a sense of proportion, tightening the mounts evenly on both sides.
If the scooter hums or twitches after assembly, check the connection of the motor connector. Oxidized contacts or poor connection give exactly such symptoms. Clean the contacts with alcohol and make sure that the fixation is reliable.
If the wheel is tightly spinning "from the hand" (with the scooter off), check the brake disc. It may touch the pads or the caliper is squeezed. Adjustment of the brakes is a mandatory procedure after any work with the wheel.
