How to remove the rear wheel on the Xiaomi M365: the complete guide

The Xiaomi M365 series is well-deservedly popular for its reliability and availability, but like any appliance, it requires periodic maintenance. One of the most common challenges owners face is accessing the rear motor wheel, which may be required to replace a punctured camera, install a more wear-resistant tire or check the condition of the engine winding.

The dismantling process seems complicated only at first glance, but requires strict adherence to the sequence of actions and the presence of a specific tool. Incorrect execution of operations can lead to damage to power cables or failure of threads on the bolts, so it is important to carefully study the theoretical part before starting work. In this article, we will discuss in detail each step, from the preparation of tools to the final assembly of the site.

The rear wheel in the Xiaomi M365 is an integral part of the electric powertrain, not just an inert chassis element. Inside the disc is an electric motor that is sensitive to moisture and mechanical shocks, which is why accuracy when disconnecting wires and removing the wheel from the axle becomes critical for the further operation of the scooter.

Before disassembling, make sure the scooter is off and the battery is disconnected from the onboard network, if possible in your modification. Working with electrical components requires caution, although a voltage of 36 volts is considered conditionally safe for humans, short circuiting in the controller circuit can put expensive electronics out of order. Prepare a clean workspace with good lighting, so that small parts and fasteners do not get lost.

Tools and workplace preparation required

The quality and speed of the work depends on preparation. To dismantle the rear wheel, you need a set of tools that you want to assemble in advance, so as not to interrupt the process of finding the right screwdriver or key. The main element of the fastener is the axis nut, which requires the use of a powerful collar or a specialized head.

You will need the following tools:

• 🔧 Set of hexagonal keys (mandatory keys for 4, 5 and 8 mm).
• 🔩 End head 10 mm with a collar or rattle (for the wheel axis nut).
• ✂️ Plastic mounting blades (for careful snapping of covers).
• 🧤 Gloves to protect hands from dirt and sharp edges of metal disc.

Special attention should be paid to the condition of the faces on the bolts. If the scooter was in use for a long time, the fastener could acidify or corrosion, in which case it is recommended to pre-treat the threaded joints with penetrating lubricant, for example, WD-40, and leave for 10-15 minutes, this will greatly facilitate the unwinding process and reduce the risk of licking the faces.

⚠️ Warning: Do not use an impact screw to unscrew the axle nut unless you have experience with it.Excessive torque can damage the engine shaft or break the thread, which will lead to the need to replace the entire motor wheel.

The workplace should be stable. It is ideal to turn the scooter upside down, putting the steering wheel and seat (if any) against the soft surface, or use a special stand that locks the frame, which will provide free access to the bottom of the structure and allow the wheels to be twisted to check the course after assembly.

Dismantling of brake caliper and wing protection

The first step in the disassembly process is to free up space around the wheel. The rear wheel of the Xiaomi M365 is tightly surrounded by brake elements and a protective wing that prevents its removal. You should always start with the brake caliper, since it attaches directly to the frame and blocks access to the axle.

To remove the caliper, you need to twist two bolts located on the inside of the pendulum. Use a hexagon of the appropriate size (usually 4 or 5 mm). After unscrewing the bolts, the caliper does not need to be completely removed from the scooter - just take it aside and hang it on a wire or rubber band so that it does not hang on the brake hose.

Next, you have to do the protective wing, and it's mounted with a few screws to the frame and bracket of the stop light, and you have to carefully unscrew all the visible screws that hold the plastic lining, and often you have the tails of the wires that go to the headlight and the stop light under the wing, so you can't make any sudden movements.

💡

When removing the wing, check the status of the stop light immediately, and often the reason for its failure lies in a rubbed wire at the base of the mount, where moisture and dirt enter.

After removing the main part of the wing, it may be necessary to dismantle the metal extension plate if it interferes with the free movement of the wheel when removing. Make sure that all fasteners are folded in a separate container, as they tend to be lost at the most inopportune time.

Disconnection of motor connectors

The rear wheel in the Xiaomi M365 connects to the controller through phase wires and Hall sensors, which are inside the hollow axis of the wheel and sealed, and your task is to gently disconnect the connector that comes out of the axis from the response part on the frame or in the deck.

The connector is usually on the right side of the axle (when you look at the scooter from the back) and is closed with a rubber or plastic cap. You need to remove the plug and carefully pull the connector. It can sit tightly, so you can easily sway from side to side, but you need to pull the housing of the connector, not the wires.

• 🔌 Find the main connector exiting the hollow axis of the motor-wheel.
• 🛡️ Remove the protective rubber cuff that protects contact from moisture.
• 👐 Carefully uncouple the chip, avoiding jerks that can break thin veins.

In some versions of the scooters, the wires can be additionally fixed with plastic clamps or tape to the frame, they need to be cut or unbuttoned. After disconnecting, make sure that the contacts inside the connector are dry and not oxidized. If you plan to disassemble for a long time, it is better to isolate the connectors with scotch so that dust does not get there.

⚠️ Warning: It is strictly forbidden to disconnect the wires under voltage. Make sure that the scooter is turned off by the power button, and ideally - disconnect the battery connector from the controller before starting work with the electrician.

Once the electric is turned off, the wheel axis is completely free for mechanical dismantling. Now there's nothing to stop the wheel from being removed except for the nut that holds it on the pendulum. Make sure that the wiring is not stretched and is free so that it doesn't damage it during the wheel removal process.

Removal of the wheel from the pendulum axis

Now, to the most important mechanical step, the wheel is held on the pendulum axis by one nut on each side, but because of the design of the Xiaomi M365, access to the nut is often difficult. The nut has a turnkey thread of 10 mm and is twisted with great force.

Use the end head and the collar to unscrew. If the nut fails, you can carefully heat it with a building hair dryer (not open fire!) to expand the metal and break the corrosion layer. Sharp hammering on the handle of the collar can also help break the boiling thread, but act carefully so as not to damage the aluminum pendulum.

Once the nut is unscrewed, remove the puck and gently pull the wheel off the axle. It can sit tight due to a diameter landing. If the wheel is not removed by hand, you can slightly shake it or use a wooden kievah for light taps on the tire (not on the disc!).

When you remove, be careful of the wires coming out of the axle, they go inside the hollow axis and out the side, if you jerk the wheel sharply, you can damage the insulation or the wires themselves around the edge of the frame, and smoothly pull the wheel back and down, controlling the output of the wire tourniquet.

After successful dismantling, inspect the pendulum axis for production, rust or dirt, and it is recommended to wipe the axis with clean rags and lubricate it with a thin layer of graphite or lithium lubricant before re-installation, which will prevent the wheel from boiling in the future.

Disassembly of the wheel: replacement of the camera and tires

If your goal was to change the camera or install a new tire, then after removing the wheel from the frame, you need to disassemble the knot itself. The tire on the Xiaomi M365 sits very tightly, and it will require special blades and physical strength to remove it.

Procedure for replacing rubber:

• 🎈 Detox the air from the chamber completely by twisting a nipple.
• 🔨 Use the mounting blades to fit the side of the tire behind the rim of the disc.
• 🔄 Move around in a circle, gradually removing the tire from the engagement with the disk.

Removing the rear tire is often harder than the front tire because of the motor inside. Be careful not to damage the wires coming out of the axle when using the shoulder blades in this area. After removing the old tire and camera, thoroughly wipe the inner surface of the new tire with talc - this will prevent friction and heating during operation.

When you build it, it's important to position the camera correctly so that it doesn't get pinched between the disc and the tire. Pump the wheel to a slight pressure, check the uniformity of the landing, and only then bring the pressure to the working value (about 2.5-3 atmospheres).
