Kingsong KS-16X. Disassembling. English version.

This time we are quite late with the dismantling of the wheel. I apologize in advance for the huge amount of dirt and dust inside – we’ve rode a lot on this wheel. Let’s remove the pedals first.

The pedals are equipped with only one setscrew. The axis can be knocked out through a hole on the other side of the pedal.

We twist off 8 screws around the perimeter under the lining:

A pair of screws is located at the very bottom next to the pillar:

Side panel can be easily removed:

Magnet to hold the pedals:

Side panel pillar with the left screw:

Kingsong KS-16X without it’s cover:

Unit with rear lights:

In order to remove the battery we should unscrew it:

There is a pair of speakers at the bottom:

And one more on the top of the wheel:

All in all, there are 3 speakers per side, that means 6 speakers in total and one big speaker on the rear panel. Interestingly the sound is much better without the side panels. High frequencies are not cut off that much. LED line goes all the way around the wheel:

To replace the chamber in the motor we need to remove this line:

Kingsong have wittily foresaw this moment. The bottom of the line is not glued and comes off easily:

So taking out of the motor to replace the chamber will not be a problem at all. The only small drawback in comparison with the previous models is that now you need to remove the pedals for this procedure. Telescopic handle guide with the wheel lifting sensor (microswitch):

One of the side panels bindings:

All pillars for screws are additionally reinforced with the stiffener. Wire connections:

Everything is just like in 18L: MT90 connectors are used both for power wires of the motor and for batteries connection. There is enough space for the wires, they are slightly recessed so that they do not hang out:

Now we are taking out the battery:

Battery connection is quite standard: two power wires, a charging wire and a thin red wire to synchronize overcharge protection. Alas, there is no SmartBMS.

We’ve contacted Kingsong on this point. They’ve replied that, in their opinion, SmartBMS consumes additional energy when the wheel is off, complicates the design and generally reduces reliability of the wheel. I disagree with the Kingsong’s engineers. In my opinion, this is just a desire to save some money. Although, I must admit that SmartBMS is a very frequent problem with Ninebot Z-series wheels. KS-16X without the battery:

On this side of the motor we can see the outlet of power wires of phases.

View of the body from the other side:

Like the other 18″ Kingsong models this one has the cable on the other side of the motor for Hall and temperature sensors connections. So now we are unscrewing the upper panel:

Here we can see 4 screws on each side:

The panel lifts easily:

The controller is slightly recessed:

Let’s have a closer look:

Now we are removing the edge panels. Front one first:

This cover has the headlight and USB ports:

Under the huge flashlight board there is the power button and photosensor board:

Here is how the front part of the body looks like without the cover:

The rubber bumper is located below. Let’s remove it:

The front of the body without the bumper:

And here is the rubber part by itself:

The splasher on the other side can be also removed in the same way:

The splasher separately:

Under the rear panel there is the largest speaker which acts as a subwoofer in this wheel:

Look of the body above the speaker:

Now let’s unscrew the pedals:

Pay attention to the extra finning of this part of the body. This should increase the reliability and prevent cracking of the body on this side. Now we are removing the cover from the motor:

Motor with pedal pillars:

Kingsong very abundantly filled the wires with sealant:

And on the upper sponge pillar there is a hole added for the body. Let’s look into the wheel arch:

The radiator is in its own little in-depth niche. This will somewhat worsen the cooling but, on the other hand, it made the wheel arch more round so that dirt and especially snow could not collect above the wheel. There are no metal parts inside the arch. These are the slightly raised pillars that hold the rare lights:

Now we are removing the controller. Here is the radiator:

The niche of the radiator is provided with a foam gasket:

Marking of he KS16X v1.1 controller:

The size of the controller is exactly the same as in KS-18L:

The location of the details is slightly different and the battery synchronization wires are soldered directly to the controller. Motor weight with pillars and tire:

It’s almost 11kg. The motor is very heavy. Now here are the pillars separately:

Notice how far is located the axis of the pedals. Also pillars but from the different angle:

The motor was very hard to disassemble. The covers were located very tightly, the sealant also did not allow us to manage all the work quickly. When we removed the covers I noticed two welding spots on the engine axis:

This method protects the axis from backlash but the axis can no longer be replaced. Here is the rim with magnets:

Each magnet is 3cm wide:

Gotway uses motors with the same magnet width. The magnetic core is of course 3cm:

Diameter of motor axis:

Bearings are standard – 6203RS:

The magnet cover is smeared with something blue:

Most likely, it is some kind of waterproofing. Motor windings:

The winding is dense, voluminous, uneven, crumpled on top. On the other hand, everything here is fixed with twine:

Although one segment of the wire remained without fixation:

Kingsong has changed engine manufacturer. And in terms of the quality of execution I personally don’t really like the new factory. It all could’ve been assembled much neater. In addition, I know that this batch of motors turned out very problematic which resulted in some questions from the riders. Some people say that the wheel is quite wobbly, in our case, it had a very noticeable vibration while driving. We are waiting for the serial version of the wheel where all minor problems will be eliminated. Stay tuned and follow our blog.
