A few words about who I am: I have been dealing with high-performance electric scooters for a few years now. I have been playing with lithium batteries (and building battery packs) for many years. I have also been building electric bikes for a few years... I really like electric vehicles and have done a lot of research and hands-on work in the whole technology.

The 3 stars only concern someone knowledgeable about the subject. A regular buyer might give it 4 stars.
Now regarding the tiger after 3000km:
I knew what I was buying. A Chinese electric scooter with somewhat decent Chinese battery. I wasn't expecting miracles. However:

Positives:
• Decent, easy handling while driving, it's not terrible.
• It pulls okay, has no issues on inclines, etc... Up to 100-110 km/h on most roads it will take you. On a long and somewhat tough incline where most vehicles struggle, I guess it might go 60-70km.
• Relatively nice and low-key. It doesn't really look electric.
• It doesn't creak much... the windscreen might resonate a bit in some potholes, but generally, it doesn't creak. Very important for an electric vehicle.

Medium Points:
• Brakes. They are not amazing... Decent. There is electronic brake assistance which helps a bit... The new model I got has ABS. Personally, in emergency situations I found myself in, the scooter stopped, but with significant uncertainty... The electronic braking should have levels; when you pull the lever hard, it gives it all. However, there is a slight delay. Additionally, its own brakes are not particularly strong. If it didn't have electronic braking, the vehicle probably wouldn't stop (and don't listen to the shopkeeper that it doesn't have... it does...). So it relies heavily on that, and this thing has a slight delay. It causes some uncertainty in sudden braking. As for the ABS, mixed feelings... If you brake and there are little potholes, goodnight... it does more harm than good there. On smooth roads, it works nicely though.
• Battery. Forget about the 200 and 260km range... Forget about the 8-year warranty...
Some facts: The scooter gives 130km in an outside temperature of 6-7°C. Slightly higher temperatures will give slightly more range. This at level 3 and if you are lightly chasing it. For me, this matters. If I put it on level 1, yes, it will give me 200+ km, but I will be going like an electric bike. On level 2 it might give 170km, but you will feel like you are on a 80cc scooter.
8 YEAR WARRANTY. HA! Marketing nonsense...
or 80,000km.
If you do what I do, which is 100km a day, in about 3 years you will hit 80,000km. However, not everyone is like that. If you ask the store, they will tell you that the battery will be at 50% health after those 8 years. If you drop below 50% before the 8 years, it covers you, let's say. How they will measure that is another story xD Below 80%, lithium batteries are practically considered useless. They lose tremendous range from that point onward. So roughly at 6-7 years the battery will have dropped below 80% and in the next 1-2 years it will be nearing 50%.
I leave the continuation for you to think about on your own, but don't expect the battery to work for more than 1-2 years after that point, regardless of range. Cells will start dying. All of this, based on the funny 50% they told me. If they had told me 80% like all serious manufacturers, I would have been much more positive.
Oh! And one more thing... To achieve this for 8 years, they do not allow the battery to discharge below ~40%. This means that the scooter practically has monstrous autonomy, but it is not allowed to let the battery drop low. This has other implications... At the fictitious 20%, you start losing a lot of power and some speed, at 18% you lose a lot of power and quite a bit of speed, at 17% you go at 50 km/h, at 16% at 40, at 15% it starts to sputter and you go at 20-25 on flat ground. Yes, I was stuck xD There was a gas station there and I begged to charge. I looked at the cell voltage when I was stuck and it was at 3.5V. Seriously, are you kidding us? Even down to 3V is totally safe for Li-Ion batteries... At 2.5V it's absolute 0%...
• Warranty. They don’t shout it out, but besides the battery, the rest only have a 2-year warranty.

Negatives:
• According to a friend who rides motorcycles, he got on to ride it and the vehicle had terrible instability, something strange he says is going on. Personally, I’ve been riding weird vehicles for years, I didn’t notice anything... But you definitely can't call it well-built. It has steering wobble if you let go of the handlebars.
• Tires Of course, you change them upon purchase.
• LIGHTS. The lights are ridiculous. One LED on each side. It barely illuminates on the "middle setting." I have the impression that sometimes they don’t see me coming and jump out in the alleys... This is the impression I’ve gotten from the surprised faces of drivers who made the mistake. The high beams, a bit meh again, but in the city, you will blind people... I asked a seller and he told me they don’t change if I want to put something better. I see other scooters next to me and their middle beams light up the whole road. I look at mine and I have some poorly diffused lines of light showing on the road without any particular illumination. In my opinion, unsuitable.
• No accuracy in battery percentage. From 100% to 90% you do 30 km. From 90-80% about 15 km. From 80-15% about 80 km. And in reality, 15% is 0% since the scooter practically stops moving. You turn it off at 15%, you turn it back on after a while at 8%. Dumb-calibrated BMS...
• Locked BMS and intimidating sellers. Both the calibration for the percentage and the fact that the battery does not discharge below 40% change if you have the code for the BMS. Do I have the code? Maybe :) Will I mess with it? Maybe :) But the sellers after the purchase practically told me "don’t you dare mess with it because you automatically lose the warranty." Um... There is a European court ruling that refers to the right to repair. Practically, you can do whatever you want to the vehicle, as long as you don’t cause damage. Now if the company promises 8 years warranty on a battery that is for 5 because they locked it, but practically gives you the ability to unlock it, legally it is not considered damage... They shouldn’t even give the option like every serious company does...
• Power. The vehicle sellers promised 18kW of power. Because the BMS is 250A. xD Okay, but it’s locked, brother... Theoretically, when fully charged, the vehicle goes up to 21kW, but it won’t give more than 150A... And that’s not at 84V, 81.6V is fully charged. So ~12kW of power. Nothing to do with the dreamy 21kW.
For me, this was and is a messed-up situation that they threw at me as soon as the purchase was completed "You can’t mess with settings, no! While before "Yes, yes, 18kW, 21kW"...
All good...
You might ask what do you want with 28 horses... Exactly because I’ve been playing with electric vehicles for so many years, I knew more or less what performance the vehicle would have at 21kW with this weight... And I didn't get these performances... And because I'm used to rapid speed increases and this doesn't give them to me, I get a bit annoyed... Practically, I can tweak it and instead of the battery lasting "8 years," it could last "6 years." Anyway, in 3 years I'll have hit 80,000 km. Practically, it will come out to 73,000 km unlocked... 10% loss for almost double the power... But I can't. Because anything that breaks will be told to me "ah, you messed with it, you don't have a warranty." Which legally doesn't hold up, but I'm not going to take it to court... So I don't feel like figuring it out, so I won't mess with it... When we hit 80,000 km and go for a battery change, either I'll make my own package and know exactly the specifications and unlock everything, or I'll buy from them, I'll see how I feel then...
• Generally, they'll tell you it's a beast, very fast, 18 kW xD It's not... It's around 12 kW and programmed to gradually increase. If you've ridden an unlocked wild electric motorcycle, it's nothing like that xD 0-100 about 7-8 seconds. Nothing crazy. Can it do it in 4-5? Maybe :) But it's locked. So adjust your expectations.

All in all, it's decent. It does its job. But it's not what the seller promises you. They'll promise you the moon, you should adjust your expectations beforehand.
There are other things I could write, but they are technically silly little issues that concern me, not most people.
This review was from the perspective of a burnt-out electric enthusiast, not a motorcycle rider. Motorcycle riders will definitely find more to say.

The first 1,000 kilometers have been completed. I have been the owner of the economical model with an 80Ah battery for about a month.

I will analyze my experience so far and will provide an update at 5,000 kilometers.

- Speed. This vehicle is FAST, and when I say fast, I mean that even 250cc scooters are left behind at the traffic light until 80 km/h. However, it is classified as a 125cc, but my insurance classified it as a 150cc. Its torque is constant from 0 to 80 km/h. Above 80 km/h, it gradually decreases until it reaches 110 km/h. The throttle response is very sharp and requires getting used to because it is instantaneous. It easily climbs steep hills where other scooters struggle and the motor heats up.

- Range. I haven't tried to fully deplete the battery, but I can confidently say it can go 100 km without any economy and with full throttle (always with safety precautions). With a calm hand and low city speeds, I believe it can reach 150 km. Charging takes about 5 hours from empty. However, there is also a fast charger that I have installed, which takes about 1.5 hours to charge from 50% to full.

- Excellent handling. It is perfectly balanced with a low center of gravity. It is a bit slow in maneuvering at low speeds, but performs exceptionally well on larger roads at 40 km/h and above.

- Brakes. Let me provide a brief analysis for this. The right lever activates the regenerative electronic brake as soon as you lightly press it, which slows down the scooter like releasing the throttle in 3rd gear. This also slightly charges the battery (barely noticeable). When you press the lever a bit more, both pistons of the front brake engage, which stops the vehicle comfortably, but it doesn't provide the best feel. The left lever activates the electronic brake with a light press. With a slightly stronger press, both rear pistons and one front piston from the triple-piston caliper engage. This brake is called CBS (combined brake system), which is compliant with EU regulations and can be found in many electric vehicles. Its effectiveness is very good, and when you press it, the scooter stops with a smaller chance of wheel lock and skid. When both levers are pressed together, all the brakes (5 pistons and the electronic brake) stop the scooter in a very short time. It does not have ABS.

- Suspension. This is its weak point, and I would recommend an upgrade, which I am planning to do once I am sure they won't improve within the next 1000-1500 kilometers. It is compatible with other brands, but I am still researching to find the YSS model that fits.

- Material quality. It is moderate, but overall okay. I would easily compare it to DAYTONA.

- Appearance. Objectively, it looks nice, but it has a slightly outdated design from 4-5 years ago. It is basically a copy of the old Yamaha Nmax with minor differences. To give you an idea, the Tucano Urbano cover for the Yamaha Nmax 2016 (r180 model number) fits perfectly on this scooter, tested and confirmed. The LED lights are very nice and effective at night.

- There are no electronic gadgets like applications with settings, GPS tracking, keyless entry, etc. The instrument panel is simple with an automatic day/night mode and good visibility in sunlight. It shows speed, battery percentage, battery voltage indication, motor power (something like RPM), total odometer, and partial odometer (reset by pressing the turn signal lights PASS button five times). The vehicle also has a reverse gear, which is very useful in the city for parking and maneuvering as it is relatively heavy. With the alarm installed by the dealer, there is a button that activates it without using a key (costs 60€). It does not have a connection for upgrades or an OBD connection for controller diagnostics.

- Storage spaces, there are two or three, but without a trunk, a helmet (not even a jet helmet) does not fit. One is under the seat, it can fit a full supermarket bag. Without measuring it, I estimate it to be around 25 liters with low height. The second one is under the handlebars, about 2 liters with a small opening, so it's not easy to fit a bottle. It also has a USB charging port. Finally, there is a third one on the floor between the legs and it looks like a fuel tank. This one opens with the scooter key. I use it to put my coffee or water, but it has depth inside and small items can fit.

- The battery used by this manufacturer is the best on the market. The company CATL supplies batteries to Tesla, Toyota, Volvo, and many others. It is a pioneer in its field, which is why it offers an 8-year warranty or 80,000 km, the longest in the market (that's why I chose this scooter). Its main competitors are Samsung, LG, and Super Socco, which only offer a 2-year warranty. I would recommend avoiding any other brand apart from these four. As for replacing the battery, it will definitely be expensive, but prices will change in the next 8 years. In any case, it can be replaced with another brand, and the depreciation will already have occurred. In the first 1000 km, I have already saved 100 euros on gasoline compared to my diesel car, which is a Euro 7 1300cc with an average consumption of 4.5L/100km and a fuel price of around 2.00€. The battery CANNOT BE REMOVED, so you will need parking or a charging space, and a simple household power outlet is enough.
As for electricity consumption, I didn't see a big difference, I estimate around 4 euros per 1000 km. I will install a meter on the power outlet and come back with statistics.
UPDATE: One detail I didn't mention is that the manufacturer recommends, for the battery's health, not to let it drop below 30% unless necessary (I imagine it doesn't affect the warranty as there is no way to check).

So far, I haven't had any issues with the electronics except for two times when it had a glitch and I had to reset the main fuse under the seat. Specifically, one time it wouldn't switch from reverse to normal speed, and another time it wouldn't reset the partial odometer. I don't find it unreasonable for a controller to have minor glitches, but it's not pleasant when it happens.
I have driven it in the rain and on wet roads, and I haven't encountered any problems, but I avoided deep puddles.

Upgrades for motors and controllers have started to be done by some workshops slowly. I believe that in a few years, there will be a lot of space and options for upgrades, with the excellent battery and well-built scooter as a solid foundation.

I will follow the discussion for any questions I can answer.
