How to remove the rear wheel from the Xiaomi scooter: instructions for the M365, Pro 2 and Essential

Removing the rear wheel on a Xiaomi electric scooter is a task that every owner faces sooner or later. Whether you plan to replace a punctured camera, update brake pads or just do a preventive inspection, properly dismantling the wheel will avoid damage to the wiring, bearings and other critical components. In this article, we will analyze the process by steps, taking into account the nuances of popular models (M365, Pro 2, 1S, Essential), and also warn against typical errors that can lead to expensive repairs.

The back wheel of Xiaomi scooters is an integration with the electric motor and the braking system, which means that in addition to mechanical attachments, you have to work with power wires and sensors. Without preparation, it is easy to damage the connectors or squeeze the cables, which can lead to loss of traction or failure of the controller, we will describe in detail what tools you will need, how to safely disconnect the electrical components and in what sequence to disassemble the assembly in order not to disrupt the factory assembly.

Important: if your scooter is warranty, self-repair can cancel it, in which case you should contact the Xiaomi service center. For the rest, go to the step-by-step instructions!

What tools will be needed to remove the wheel

Before you start, prepare the right toolkit, and without it, you risk breaking the thread, damaging the plastic parts, or not being able to unplug the connectors.

• 🔧 Hexagonal key 5 mm - to unscrew the main bolts of the wheel mounting (in some models, a size of 4 or 6 mm may be required).
• 🔧 End key or head 14 mm - for the axle nut (complete with a collar or rattle handle).
• 🔧 Flat screwdriver - for tweaking plastic covers and fixers of connectors.
• 🔧 Flatheads or round-killers - can be useful for removing stop rings or holding nuts.
• 🧴 WD-40 or similar lubrication - if the bolts are sour or rusted (especially important after driving in the rain).
• 📦 Plastic tray or box - for sorting small parts (nuts, washers, bolts).
• 🔌 Multimeter (optional) - to check the integrity of the wiring after disconnecting the connectors.

Xiaomi Pro 2 and 1S models may additionally require a special stop rings receiver if the wheel is fixed not by a standard nut, but by a groove ring. Also prepare a clean cloth to wipe the dirt and oil parts that inevitably accumulate in the rear wheel area.

⚠️ Attention: Do not use percussion tools (hammer, chisel) to unscrew the nuts that have become stuck! This can deform the axis or damage the thread. If the nut fails, treat it. WD-40 And wait 10-15 minutes.

Preparation of the scooter for the dismantling of the wheel

Before you can get your tools, you need to prepare the scooter properly, and this will save you from injury and damage to the equipment.

1. Turn off the scooter — press and hold the power button for 3-5 seconds until the indicator goes out. This will prevent the engine from accidentally turning on while running.
2. Remove the battery (if possible). In the M365 and Pro 2, the battery is removable — press the lock at the bottom of the deck and pull the battery up. The Essential battery is built-in, so skip this step.
3. Turn the scooter over so that it is on the steering wheel and the front wheel. Put a soft stand under the deck (for example, a folded towel) so that the plastic does not scratch.
4. Clean the back wheel of dirt with a brush or a wet cloth, which will help avoid sand getting into bearings or threads.

If you remove the wheel to replace the camera or tire, flush the air out of the tire beforehand. To do this, press the nipple (it can be hidden under a plastic stub) and let the air out completely. In models with tubeless tires (for example, Xiaomi Pro 2 with a tire 8.5), this step is mandatory — otherwise the tire will interfere with the dismantling.

Step-by-step: how to remove the rear wheel

Now, to the main process, follow the instructions in strict order to avoid missing important details:

Step 1: Removal of plastic cover and brake pads

On most Xiaomi models, the rear wheel is covered with a plastic cover that is mounted on latches or screws. Carefully tuck it in with a flat screwdriver starting at the edge and remove it. Under the lid, you will see:

• Brake disc (if the scooter is equipped with a disc brake system).
• Brake pads (in models with drum brake).
• Power connectors of the engine and speed sensor.

If your scooter has drum brakes (as on the M365), the pads are attached to the wheel with two bolts. Unscrew them with a 5 mm hexagon and carefully remove the pads without losing the springs and locks. In models with disc brakes (for example, Pro 2), the pads do not need to be removed, but they need to be diluted so that the disc does not interfere with the dismantling.

Step 2: Disconnecting the electrical connectors

This is the most critical step. If you turn off the connectors incorrectly, you can short-circuit or damage the controller.

1. Find two main connectors: a white or black connector with 3-5 wires - power the engine. A small connector with 2-3 wires - a speed sensor (hall sensor).

If the connector fails, do not apply force - drop a little WD-40 at the connection point and wait 1-2 minutes.

Once the connectors are disconnected, insulate them with tape or place them in separate bags to avoid moisture or dirt on the contacts. If you notice oxidation on the connectors, clean them with alcohol or a special contact fluid.

Step 3: Unscrewing the nuts and removing the wheel

Now that the electrical part is disconnected, you can proceed to mechanical dismantling:

1. On one side of the axis, you'll see a 14mm nut (sometimes 15mm depending on the model), fasten the scooter so it doesn't spin, and unscrew the nut with a counterclockwise end key.
2. On the other side of the axis, there can be either a second nut or a locking ring (in Pro 2). If the ring is used, use a receiver or gently tuck it in with two screwdrivers.
3. After removing the nuts, gently pull the wheel on yourself, holding the axle. If the wheel does not come down, slightly wobble it from side to side to free the bearings.

Another common problem is that the speed sensor (hall sensor) is damaged, and it's located next to the wheel axis, and it's responsible for transmitting rotation data to the controller, and if the scooter twitches or doesn't pick up speed after assembly, check if the sensor is connected correctly and if its wires are damaged.

⚠️ Note: If the scooter does not turn on after assembly or gives an error E014 (engine malfunction, you're probably incorrectly plugged in the connectors or damaged the wires.

How to install the wheel back: key points

Rear wheel assembly is a reverse-disassembly process, but with a few critical nuances.

1. Installation order: Put all the washers and spacer bushings on the axle in the same order they were removed. Set the wheel on the axle, combining the bolt holes for the brakes (if any). Twisted the nuts first by hand, then tighten the key.
2. Connect the connectors -- connect them until the lock clicks, and make sure that the wires are not stretched or twisted.
3. Checking brakes - after installing the pads, press the brake lever several times so that they stick to the disc or drum.
4. Test start - before the first trip, turn on the scooter and check: The wheel rotates freely, without jamming. The engine runs smoothly (no jerks or extraneous sounds).

If the scooter makes a creak or hum after assembly, you probably pulled the nuts or installed the bearings incorrectly. Relax the mounting and check the backlash of the wheel - it should be minimal (no more than 1-2 mm).

💡

After installing the wheel, be sure to check the engine at minimum speed. If the scooter is twitching or not going, immediately turn it off and recheck the connection of the connectors.

When is the best time to contact the service

Although removing the rear wheel on a Xiaomi scooter is a task feasible for most users, there are situations when it is better to trust the professionals:

• 🔌 Wiring damage – if you notice melted wires, short circuit or break, self-repair can be dangerous.
• 🛠️ Engine malfunction – if after assembly the engine does not work or warms up, the problem may be in the winding or controller.
• 🔄 Controller errors - codes E014, E015 or E022 Often require diagnosis with specialized software.
• 🔧 Complex mechanical damage - cracks in the axle, deformation of the brake disc or wear of bearings is better to eliminate in the service.

The cost of replacing the rear wheel in official service centers Xiaomi ranges from 1,500 to 3,500 rubles (depending on the model and type of work).If you are not sure about your skills, compare this amount with the cost of possible errors - sometimes self-repair is more expensive.

Also contact the service if your scooter is warranty. Self-intervention can cause a denial of warranty service, even if the breakdown is not related to your actions.
