Operating the popular Xiaomi M365 or its more powerful Pro versions inevitably confronts owners with the need for maintenance. Most often, the question of how to remove the wheel from the Xiaomi electric scooter arises when the camera is punctured, tire wear or the need to replace bearings.
The dismantling process differs depending on whether the wheel is to be removed, the front or rear. The design of the motor-wheel requires more attention to electrical connections, while the front axle is primarily a mechanical task. Understanding these differences is critical to maintaining the warranty and performance of the device.
In this article, we will discuss in detail the algorithm of actions, the necessary tools and specific nuances for different models of Mijia scooters. The correct sequence of steps will save you from damaging the frame or rupturing the plumes of speed sensors.
Required tools and workplace preparation
Before you start dismantling, you need to prepare the workspace, the ideal bench or a wide table, covered with clean fabric, so that small parts do not get lost and scratched, to perform the work, you need a specific set of tools, the presence of which guarantees the safety of the process.
The main tool will be a set of hexagonal keys, most often sizes 4 mm, 5 mm and 6 mm. To unscrew the axle nuts, you may need a carob key of 14 mm or 15 mm, as well as a powerful screwdriver used as a lever.
- 🛠️ Allen Keys (Set of Hexagons) of the Metric Standard
- 🔧 Carrot or captive keys on 14-15 mm
- 🔋 Powerbank or charged battery to check the motor
- 🧤 Gloves to protect hands from lubrication and sharp edges
It is also recommended to have a multimeter on hand to check the integrity of the engine windings if the replacement of the wheel is due to a malfunction.Make sure in advance that you have spare cameras or tires if this is the purpose of the repair.
💡
Use a magnetic tray or a regular lid from the can to put all the screws there during the disassembly process - this will prevent the loss of small fasteners.
Preparation of the electric scooter for disassembly
The initial phase requires the power cut off, turning the scooter upwards with the wheels, placing it on a soft surface so as not to damage the display and control handle, which provides easy access to the bottom of the frame and wheels.
The first step is to disconnect the battery. In the Xiaomi M365 models, the terminals are accessed through the bottom hole in the deck or by removing the bottom cover. Disabling the battery is a critical step to prevent short circuits when working with the motor-wheel wires.
⚠️ Warning: Never start working with the electric components of the scooter without turning off the main power source.Sparking can cause the controller to fail or fire.
If you plan to remove the rear wheel, it is advisable to immediately relax the tension of the brake cable. To do this, use the adjustment nut on the caliper or disconnect the cable completely so that the pads do not interfere with the removal of the disc.
☑️ Preparation for the removal of the wheel
Dismantling of the front wheel
Removing the front wheel is a less time-consuming task than the rear, because there is no electrical connection, and the process begins with unscrewing the screws that hold the hub lid on one side, usually four, and they are located around the perimeter.
Once the lid is removed, the axis nut will be accessed. In some versions of Xiaomi scooters, the nut can be hidden under a decorative plug. Use a key of the appropriate size to unscrew the axial bolt.
It's important to pay attention to the condition of the bearings and bushings. When you remove the wheel, you often find that the bushings need to be replaced or lubricated. Carefully remove the axle and remove the wheel from the fork. If it's stuck, sway it slightly from side to side.
- 🔩 Unscrew 4 screws on the hub cover
- 🔓 Unscrew the central axial bolt with a key
- 🛞 Remove the wheel by holding the fork
- 🧐 Check the condition of the sleeves and bearings
When reassembling, make sure the bushings fall into place smoothly. Misfitting can cause the rubber to wear quickly and the wheel to beat when moving.
Removal of the rear motor-wheel
Replacing the rear wheel with the Xiaomi M365 Pro or the base version requires special care due to the presence of electrical wires. After disconnecting the battery and removing the brake caliper, you need to access the exit of the cable from the hub.
This often requires removing the engine cover, which is held on several screws, and underneath it is a connection of the Hall sensor plume and the engine phase wires, and in some models, the wires are output directly through the axle, and access to them is possible only through a special hole in the frame.
| Model scooter | Type of connection | The key required | Feature |
|---|---|---|---|
| Xiaomi M365 | Across the axis | 5 mm hexagon | We need to take off the lid. |
| Xiaomi Pro 2 | The connector inside the frame | 6 mm hexagon | Difficult access to the connector |
| Xiaomi Essential | Direct connection | Hexagonal set | Simplified construction |
| Ninebot Segway | Variatively. | Depends on the version. | Manual check |
Carefully disconnect the connectors. They can be fixed by plastic latches or screws. Don't pull the wires, hold on to the connector body. After the electrician turns off, unscrew the axle and remove the wheel.

Nuances of work with the tire and camera
Often, the wheel removal is required to replace the camera. Xiaomi scooters are inflated to high pressure, and it is extremely difficult to remove them from the rim by hand. Using only your hands can lead to finger injuries.
To facilitate the task, it is recommended to use special blades for mounting tires or, in extreme cases, carefully use two screwdrivers with a wide sting, wrapped in tape. First, completely flush the air from the chamber, twisting the spool.
Vulcanization or replacement of the camera should be done on the removed wheel. Make sure that the new camera is not twisted inside the tire during assembly, otherwise you may re-puncture. Before placing the wheel in place, check that the tire sat on the rim evenly throughout the diameter.
- 🎈 Reduce the pressure completely before removal
- 🔧 Use the shoulder blades for boarding
- 👀 Check for no camera torsion
- 💨 Pump the wheel to working pressure
After installing the new camera and assembling the wheel, pump it to the recommended pressure, usually 50 psi (about 3.5 atmospheres).
Assembly and final system inspection
Once a wheel or camera has been successfully replaced, you need to reverse assemble it in a strict sequence: Put the wheel in place, insert the axle and tighten the nut. Don't tighten it to the point at once, make sure the wheel rotates freely and doesn't touch the brake pads first.
Connect the motor-wheel connectors. Make sure the colors of the tags on the connectors match, if any, and that the connector snaps to a characteristic click. Lay the wires so that they don't fall into the rotation zone of the disk.
⚠️ Warning: Before turning on the scooter, double check the battery and motor connection. An error in polarity or phase order can burn the controller.
Turn on the scooter and check the engine's weight. Turn the wheel lightly and add the gas, it should start rotating smoothly, without jerking or any extraneous sounds. Check the brakes and no wheel beating.
💡
High-quality assembly and inspection of all connections before the first start is the key to safe operation of the scooter after repair.
