Electric scooter kugoo m4 pro DIY waterproofing

Major breakdowns

The main problems will be with the wheels. Pneumatic showed themselves clearly worse. They are pierced often, which requires additional time for repairs, and the transport does not work during such a downtime.

How to choose an electric scooter for sharing

Today we will consider the best electric scooters for rent. In our top of scooters for sharing, we will consider the important characteristics necessary for long-term use. At the same time, with minimal maintenance costs. Let’s find out the 4 best models of Kugoo s3, Kugoo m4, Kugoo es2 and Xiaomi m365. and briefly describe their condition after 1 year of operation.


Further, in our review of electric scooters for sharing, we highlight the top 10 characteristics of a commercial scooter.

  • Battery. The most expensive part of a scooter. Two important metrics are capacity and power. Balanced capacity 10.5 Ah. such a battery is enough for a journey without recharging for 30 km.
  • Tires. Tubeless options are good for the owner. No pumping required, care.
  • GPS tracker. External or internal hinged. When buying good electric scooters for sharing. Ninebot ES 2 or Xiami 365, a GPS tracker is attached to the steering rack. Tracker boxes will need anti-vandal.
  • Wheel motor power. Optimum power 300. 350 watts. powerful motors are not required, for beginners it is traumatic.
  • Speed. The maximum speed limit is set at 25 km / h from the factory on most scooters. Check yours, if there is no limit, install by the on-board computer.
  • Anti-vandal bolts. For the realities of electric scooter sharing in Russia, models with anti-vandal bolts are required. So as not to unscrew the wheels and take out the batteries.
  • QR code protection. An important part in such a business. Stickers and other films do not fully protect the QR code. Choose plastic glass so that customers always know where and when they took the scooter for the trip.
  • Water resistant. Waterproofing of the deck, power controller and battery pack is rarely done well. There are exceptions, these are high-quality models for Europe and the USA: Inokim OX Hero. In other cases, you need to walk through the weak points with the sealant yourself.
  • Signaling. Required for installation, plays the role of “protection from the fool”, providing protection against theft.
  • Own workshop or by contract. Scooters will often be sent for repairs, due to defects, falls, failure of electronics. Immediately think over the repair options. your own master or work under a contract with the nearest bicycle workshop.

Electric scooter Kugoo C1. detailed and honest review

What I didn’t really like was the way the steering column and steering wheel were made. Firstly, when folding, it touches the front of the saddle, if the head of the rudder is directed towards the saddle, you just need to turn the rudder to the side and it passes freely. The steering wheel itself is not folding and this was a small problem, because I had to catch both the front wheel and the position of the steering wheel to put this scooter diagonally in the trunk of the car. Well, in general, the problem is solvable and you can adapt, but as they say the test was a test, I did not adapt, but simply was not a very advanced user. Also note that when the steering wheel is folded, it rests on the skin of which the deck is covered, well, it is scratched accordingly.

On the move, the scooter behaved quite well. I did not like the creaking saddle, it would also be nice if the scooter was a little longer, with my height of about seventy-five meters. I was not very comfortable to sit, all the time I wanted to move somewhere back.

The rest, let’s go in order. First of all, let’s check the weight of the scooter, the scales are ordinary, floor scales, on which people are weighed. Roughly speaking. 21 kilograms, it turns out that the declared weight coincides with reality.

There is no fender behind the trunk and the wheel is open, respectively, all the dirt and splashes fly upward directly onto the back. Attention is drawn to how the cable is laid, going to the rear wheel, it is very bent and because of this, when the rear brake is working, the pawl or lever does not fully move away, it does not always fully move away, and if you smoothly lower the handle, then it still has a stroke. In general, the cable should be regularly lubricated and positioned so that it is curved as little as possible, there should be smooth transitions.

Regarding the brake itself, I want to note that the brake pads touch the brake rotor completely. But while we’re on the subject of brakes, let’s look at the front brake as well. The situation is similar with the front brake, the pads completely cover the brake rotor. Pay attention to the location and length of the brake lever, you can press it with two or three fingers, while it is located closer to the center, which is correct.

The total mileage of the scooter that came to me for a test drive is about a hundred kilometers and already at these hundred kilometers the front fork from excessive load, apparently when it jumped on the curbs or braked very sharply, it bent, so you still need to be with the fork be careful.

For the folding mechanism, see how it is made here. We raise the small trigger, after that we move the lever, the column is released. You need to be careful, because it immediately folds or literally falls.

The fender of the front wheel is very short and the dirt that flies from under it falls on the front of the deck, where the wires are laid. From the outside, everything seems to be great, but in winter, snow, dirt will adhere to the stiffeners through which the wiring passes, and then all this will melt very wet. It is advisable that there was some kind of mudguard here, just covering the front part with the wiring.

The deck lid was initially sharpened to be quickly opening, there is a lock with a key and if you look from below, you can see the tongue, but the lid is also screwed on with self-tapping screws, so the purpose of this lock is not very clear.

When you remove the cover, you can see the battery inside, which, by the way, is sealed around the perimeter with some kind of soft material. On the battery it says that 13S5P, the wires are located as if in bulk, but at the same time they lie quite neatly. In principle, not bad. We have a sensory motor, in fact, it was clear from the test drive, because it worked quite quietly.

Controller. The controller is declared 17 amperes, visually it is not small, but at the same time lightweight. The scooter is equipped with an alarm from the factory, as in general on the younger Kugoo electric scooters, almost all of them have it. Functions of the electric scooter signaling by buttons. this is to arm, disarm, force signal and start blocking.

The lower part of the deck is rather laconic; it is a plastic box that hangs on two guide corners. If somewhere the scooter sits on its belly, so to speak, this plastic is easy enough to break through. One thing is good that the clearance of the Kugoo C1 electric scooter is quite high, the ground clearance of the Kugoo C1 is quite automobile and is 14 and a half centimeters.

I want to draw your attention to the location of the charging port, it is at the bottom, in fact, under the deck and it is not very convenient to get to it. The controller covers are installed through silicone gaskets, and the wire outlet is well sealed. Vinyl wires, I would not say that the braid is thin, it is quite normal. Silicone power lead wire, standard. Phase wires also look like silicone.

I decided to open the controller and see what’s inside. The board is inserted into the box on a skid, which is good. The controller seems to be 6 fetovy, 63 volt. It is noteworthy that the controller board is clean, there are no oxides, no flux, nothing of the kind washed off, it is made quite neatly.

The battery itself is rather lightweight, with very sharp corners. I like the shrinkage, it is so rubbery-plastic, the ends are well closed on both sides, so greasy and greasy are smeared with sealant. We weigh. the battery weighs two kilograms eight hundred twenty grams. Battery dimensions. length 24 centimeters, width 14 centimeters and thickness 54 millimeters. I decided to dig deeper and look inside the battery box, throwing back the side cover and we can say a sandwich and elements.

Upon closer examination, I am considering a separate cell from which the battery is assembled, the declared capacity is 2,500 milliamperes hour per cell and the battery has a 13S4P configuration, and not 5P as it is written on the label! Well, in general, the configuration does not bother me much, the main thing is that it gives its 11 ampere hours. In terms of assembly, the battery was assembled quite neatly, the nickel strip is wide here, they didn’t bother too much, four points for each element, in principle, normal, not burnt anywhere. Quite neatly done, although a little clumsy in my opinion, but everything is well and neatly soldered.

The battery is fully charged, I check what is on the cells. The battery is well balanced, the run-up per cell is only one hundredth of a volt. I connected the battery to the discharge stand. At the beginning of the test, it is 25 degrees, I think on such a scooter-scooter, hardly anyone will ride with an average power of less than 350 watts, so we will carry out the discharge test with a current of 7 amperes, this is about 350 watts.

I run the discharge test and when the discharge test is over, the battery actually gave 9.7Ah or 453Wh hours. Roughly speaking, she did not give an hour and a half, from the declared 11 ampere hours. But it was difficult to expect anything else from the cells with a capacity of 2500 milliampere hours.

The battery warmed up to 42 degrees, this is not enough for such a battery.

About charging. The Kugoo C1 electric scooter comes with a charger with a built-in fan. His charge current is 2 amperes and, accordingly, he charges the battery completely for about five hours, it does not make much noise, but if left somewhere in a very quiet place, it certainly annoys, and in general it is quite normal.

While the battery is removed, you can see how the wires are laid, and they are laid in the back without sealant, and in the front without sealant, the cables are also without sealant. To assess how difficult and deplorable the situation with waterproofing in the front of the deck is conveniently from the side of the front wheel, with the battery removed, you can see the gaps that actually go into the battery box. From the factory, sealing is minimal here. In general, this scooter needs waterproofing in full.

A few words about the construction and materials of the temple. The head tube is steel, the pipes from which the frame is welded are steel, the trunk is steel, the support is steel, the front fork is also steel, the steering column and steering wheel are aluminum, well, that is, in fact, it turns out that it is all steel. a lot of weight is added.

Even at the first acquaintance from the photographs, I noticed that the Kugoo C1 electric scooter has a very small motor, although it is declared as a 500 watt one. The engine marking is as follows. 48 volts, 35P and then some kind of number. Cap-type motor nuts, protects the threads well from moisture, but at the same time they are screwed on both sides without a thread lock.

I decided to disassemble the motor and examine it in more detail. There were some minor problems with disassembling the motor, the covers were screwed on with hexagon bolts for 3mm slots, the bolts are made of soft metal and the slots break off easily, as a result I had to drill one of them in order to unscrew it. Bearings in both motor covers are protected by oil seals.

At first, the motor winding seemed to me to be quite neat, but when I looked closer, I saw a wire sticking out somewhere, somewhere a braid was punctured, but the worst thing is that the plastic substrate under the windings melted. The motor turns out to be working with overload. On the opposite side, the substrate has completely melted and we can say that it has flowed and this indicates that the engine is overheating very much. A motor with hall sensors mounted on a board, the wire lead is insulated, the width of the stator magnetic circuit is 35 millimeters, that is, the same as that of the Kugoo M4 Pro. The width of the rotor magnets is also 35 millimeters, the weight of the stator is 1 kg 600g, that is, the same as that of the Kugoo M4 Pro. The weight of the rotor with the tire is roughly 2kg 600g. The motor cover is installed on a sealant, but in general, taking into account the fact that the motor is overloaded. it is unlikely that this will help him live for a long time.

The front wheel rotates on sealed bearings. There is a persistent tube between the bearings, well, that is, everything is in order here.

Summing up the results after a short test drive and sharing my impressions of the Kugoo C1 electric scooter. Well, honestly, I want to say my impression is ambiguous, it has both many advantages and many disadvantages.

Well, let’s start with the good. The good thing is, of course, the smoothness of the ride, if not to talk about some big irregularities, potholes and potholes, and there are roots in the forest and so on, everything is fine here, large wheels can handle it. Relatively comfortable to ride, since you can ride while sitting, but the saddle creaks.

I didn’t like the throttle delay, I didn’t like the softness of the fork. who will buy, pay attention to this that you need to treat the plug carefully, do not storm the curbs straight ahead. Wings upset, really upset. During the test drive, I drove on a wet surface and my backpack and back were splattered with mud. Frustrating weight, 21 kilograms. this is not small for this class of electrical equipment, for this class of scooter. It upsets the motor, because at such powers it certainly does not withstand increased loads, although the scooter rides interestingly, I really liked how it behaves at speed. I felt comfortable and relaxed. The mechanical brakes work great, but the regenerative brake levers are odd. But of course, the quality of the battery upset me most of all, especially the fact that a battery of such a small volume or of such a small capacity was inserted into such a relatively large battery box.

Put this scooter on a motor from ES3 while making it a little bit faster, slightly stretch the deck, change the saddle to one that does not creak and is softer. and it will be very interesting, generally ideal, I would say a country scooter.
