Como Desmontar el Patinete de Xiaomi Mijia M365 [Desmontaje / Disassembly]

Xiaomi Mijia M365 - Resultados Dyno

To evaluate all the advantages of the product, it is best to simply disassemble. Especially if we are talking about the vehicle, which in any case sooner or later will require maintenance.
Let's start with the power button and a flashlight. There are doubts that there all is well protected from moisture. Remove the cover over the flashlight. On the way a couple of screws on the top and bottom.


Flashlight draws on the wire.


Turn it to 90° and get access to three bolts. These screws fix the steerer tube to the removal of the steering wheel. From a pipe in the wheel goes a bunch of wires. Place their connection hidden in silicone pouch to avoid contact with water.


Inside the stem all connections thoroughly coated with varnish. Electronics is located under the plastic cover attached with a button. Gently remove.


Inside, everything is perfect. Button also sealed in plastic and fully waterproof. Water will not have a chance.

Let's see what we have with lever brake.

Under the lid hides the Hall sensor and the magnet on which he responds. The sensor itself is thoroughly coated with varnish.

The case from the Hall sensor:

Further we'll deck. Inside closed soft plastic overlay.


She visibly sags under the screws that fasten it to the bottom of the scooter. At the screws stick out of a hat. The decision is clearly not thought out. The CAP is easy to cut when hitting the curb.


However, all coated with thread lock screws and lid fine gidroizolirovana on the perimeter with a soft material.


Inside all very skillfully. The controller and the battery are positioned in their transparent housing.

To remove the battery disconnect all wires from the controller and one under the rear wing to the tail lights.

The battery carefully promazan with sealant to prevent moisture. It is worth BMS voltage control of each cell, two of the thermode, removed the wire interface through which the controller receives the complete information about the State of the battery.

For better cooling controller is fastened to the deck through the thermal grease, which the manufacturer explicitly does not regret.

The fee covered with transparent casing, but no additional waterproofing. But it is not necessary. Bay itself is perfectly protected from water and, in the case of flood, the important thing is to not exactly got the battery.

Wires from the controller go into the pipe in the direction of the steering wheel and there zapeneny. Touch won't them.


Now, on to the engine. To get to him, we have decided to withdraw the plug entirely.


To do this, loosen the two screws under the folding mechanism and unscrew the one central screw, leading to a fork.

Inside you will need to unscrew one screw yet. And fork falls down.


The plastic lining glued red reflective strips. To get to the screws, they should be removed.


Under plastic plates are still screws from the plastic casing of the plug.

In principle, to remove the wheel, the plug entirely shoot is not necessary, because access to the axial nuts we already have. But we decided to disassemble everything.

Plug checked magnet-magnetized any fine. Steel fork, and therefore does not break the axis.

Unscrew the motor have the cover, then on the opposite side of the axle and push the stator is falling out of the mobile parts.

Considering the rotor, make sure that no additional waterproofing motor have not. There is only a small cavity under the cover that act as buffers for water penetration, so she did not ran on. Engine not worth submerged in water, otherwise the water will flood the bearings and gets inside the axis. So if you are drowned in a deep puddle engine even for a few seconds, then in any case would have to be then (return home) to disassemble the engine and thoroughly dried.

Wheelie easy revolves on two bearings, but here there is a mechanical disc brake. Parses. Begin in the same way with linings: remove red stickers, unscrew screws, remove the cover plates.

On the inner side of the already thick frame reinforced with steel inserts under the zadnju axis.

Scooter reliability at a very high level. The brake mechanism disassembled quite easily, and we can see the pads and the brake disc on a wheel with a diameter of 110 mm.

    2. Eso es lo mas fácil. Solo pliega el patinete y luego con una allen quitas el tornillo que se ve en la foto de antes de "Inside you will need to unscrew one screw yet. And fork falls down.". Por cierto, cuando lo hagas vas a ver caer una pieza de plástico, una especie de círculo abierto por un lado. Podrias decirme a donde va?

  9. Hola! Alguien sabe cómo sacar la cazoleta superior de la dirección? Es la pieza circular sobre la que montan los rodamientos y que lleva una pestaña para limitar el giro del manillar a ambos lados... He probado de mil maneras (incluso golpeándola desde la parte inferior del chasis -como se sacan las de las bicis- y no hay manera chico...) Muchas gracias!

  10. porque el motor tiene un sonido extraño a que se debe???????????

  11. Can you post the diagram at the beginning of the article but with Torque vs Speed (or torque vs rpm) please? Thank you.

  12. Patinetes eléctricos pueden haber varias marcas y opciones pero lo más importante es la autonomía que brinde la batería. Ese detalle puede hacer más caro el patinete pero vale la pena invertir en él
