![⚡ KINGSONG S20 EAGLE | QUALITY REVIEW [4K]](http://i.ytimg.com/vi/vQ2HHxVkaEM/mqdefault.jpg)
The German’s need to start making these things. EUC AMG.
10K starting price
@@NahBra_EUC going 25kph max
No joke, we already had that with the BMW scooter, total laugh show
Let's be real, with all of our regulations this would be one hell of a slow, but safe wheel to drive. I got a cheap acm2 (ooold wheel) which I drive around fields because I could get in a lot of trouble if I get caught riding a euc... big bummer around here.
@@robinferchert oh hey a German rider? I already got caught 3 years ago on my inmotion V8, the police officers even excused them selves while taking my id and stuff. Said that they actually like these devices and like how respectful I drive around other people. But they could be held accountable for me when they don't stop me. Now, after 3 years of my most boring time ever, I'll buy an S20 and just avoid roads all together. Sad, because that's where EUCs shine. In roughly what part of Germany are you?
@@robinferchert also they wouldn't make it ,,save,, , because that requires a lot of motor power, and the limit in Germany is set to 250w. Exn has like 3500w, and is still overtorqueable
One of the reasons you have a coil shock, over an air shock, is for the lack of stiction in the coil shock. Of course that advantage is gone if the stiction is back in the sliders. The sliders themselves appear to be the wrong material and there even appears to be plenty of room for ball bearing between them if the balls could be contained.
Thanks for supporting Ukraine and your thoughs Adam! Hello from Odessa!
The slider setup looks like it will wear really quickly. Should really be hardened surfaces on contact points not just some plastic/rubber blocks running on aluminium. Luckily most of the screws n bolts are made of soft cheese so should be easy to drill out when they all round off. I can see a healthy modding community for the s20 if kingsong don't address issues in later batches.
Slider mechanisms and dirt work really well together. V11 suffers from a similar design flaw.
goods news there is plenty of room for improvement from other manufactures with suspension designs.
Or maybe , One component is designed to wear and the other doesn't. Replacement of the slider pads will be a routine thing. Similar to "plastic" bushings which are used in many things built these days.
@Lemony Snicket
Gotta love planned obsolescence. Especially if manufacturers can easily charge the consumer of these nichè products absurd amounts for some bumpers and seals..
Them( sliders) are not good (gliders )...
✌️ Keeping it WHEEL ✌️
Yea, as soon as those soft aluminum channels, aka the whole battery boxes get scored a little with dirt and grit youll have a hard tail again no matter how many sliders you throw at it. Having the weight hung off center of the wheel from the back like that will make it constantly in a bind to one side. Tons of disposible parts that won't even be availible for a year. Lots of good innovations on this wheel but most are pretty poorly designed short cuts to save weight and money.
Excellent work, Adam! ... and that outro was truly amazing! Such a lovely voice!
Thank you Adam
Thanks Adam. Everything detailed and captured perfectly. Heaps of clear info, cheers mate! Good to see inside the beast.
Thanks a lot Adam for showing us all that 🙏
I have the S20 on pre-order, but unless I find any convincing reason not to I will cancel it.
The whole suspension slider mechanism is atrocious, with the channels opened next to the tire which will bring all sort of dirt/grit/sand/gravel/salt in there.
I can't imagine how this suspension not require insane amount of maintenance to run smoothly.
A really expensive time-sink 😬 no thanks.
EUCs are not made to last. Use them, abuse them, get rid of them and buy into the latest hype - at least that's what these projects seem to be designed for.
Imagine a car or motorbike breaking down after a mere 2000 miles. Consumers would see to it that the world burns.
After watching this video of that horrendous suspension I switched my deposit to the v12 high torque. For $1,000 less it's a lot better wheel for the money
Those unused tunnels look great for mods, including for mounting things on the front or back of the wheel with a screw and a nut inside the tunnel.
Or enough battery capacity to make it worth the $3,200 price tag
En tous cas grand Merci Adam pour ces vidéos toujours aussi pertinentes et sans parti pris !
Dzięki za to wideo. Uratowałeś mnie przed kupnem. :-) Jeszcze trochę poczekam, aż wypuszczą poprawione wersję.
Amazing review! Thank you very much!
Good work! ThAnk you for taking the time to make this video!!! I look forward to the Master comparison teardown - brutally honest also please.
@9:51 Please stop speculating and making assumptions about things that you cannot possibly know. Only KingSong's engineers know exactly why that is a 60 amp fuse. Given King Song's reputation for safety, we have no reason to believe that they put the wrong fuse in there.
Really appreciate the detailed tear down though 👍👍
Thank you very much for the disassembly, this review is the most correct, unlike the beautiful Kingsong rollers. The sliders are made very ill-conceived, the plastic crawls along the open aluminum profile, sand gets in there and eats up aluminum very quickly. For 2900 dollars it looks like a mockery. S18 sliders made more thoughtfully. After installing normal oil seals, they work perfectly.
That was super! Thanks. Always nice to know more - and I, like you, hope KS takes your criticisms to heart, they do seem to listen, from all reports to that positive.
FROM TIMES SQUARE NEW YORK CITY YOU GO ADAM 1 LOVE & PEACE
Take the V11 off-road and dirt sand abrasives destroys the aluminum slider rails and plastic guide tracks.
Turns out from this video he S20 is built the same... Rubber guides inside elliptical aluminum guide rail. seen (13:28 -14:14)
When a EUC is built with MX dirt bike designs (no sliders) Will be a great day for everyone
@15:30 Good points about the suspension... but the less than great sliding characteristics shouldn't matter as much when you have a heavy person on the wheel. However I have yet to try it out so I'm curious what its like. I trust you that its not great... which sucks :(
Awesome review! Thbak you!
Man, THANK YOU SOOOO MUCH for doing this things !! I wanted to do a "how too change a tire on every wheel but... pouh.... thank you !!
Now that makes sense you'd find the suspension "hard" no matter the adjustments. With this amount of friction (after so little use! Imagine after a year) no suspension can be smooth.
Cool video bruh! Very thorough.
I really dont get it anymore….
From serious fact videos back to “opinions/assumption” videos (on a test-sample/predproduction unit)
Those 3/6 bolts that you change “that make the suspension better” are mostly for setting the body(and pedal height) for the rider and are another chance to higher/lower the pedals for the rider AND adjust body shell height.
Demanding shrink wraps when the battery is in a sealed aluminium compartment is also some kind of questionable, like demanding shrink wrap in a IM plastik sealed case.
The battery btw even has a “water intrusion” detection, to see if the wheel was dumped for warranty cases, chnaging color on one of the stickers.
And btw the 60Amp fuses protect the BMS and MB from oversurges of Amps. And as THESE kind of fuses are directly reacting (instead of normal fuses used for example in GW/Veteran) they are Not to high. they react on peak surge, not constant surge.
Its pretty understandable that you have suspensions problems in general when such a light weight guy as you screws the feather down nearly to the end. It should be on the top of the screw ring, as a 750lbs spring is more for 90/100kg riders….
And just a word for the battery differencies in voltage. As it wasnt worth for you to adjust the charger, probably no balancing is happening at all in the moment.
But even then…..having them a difference of 0,013 (dont remember exact number) is totally fine…even for a unbalanced pack.
And hammering on the “shitanium” screws…..when allready KS promised to change them in mass production….remembers me of mexican loughing on the Block on the S18 “review”.
will be interesting if we get a new video when its not a Sample/preproduction unit anymore….
Sorry, just disappointed…..

This is really complex machine. My expectations quality wise was much lower. S18 still not perfect, but perfectly usable, i hope this is the same case with s20. And yeah, we need to wait at least a year for better quality. V11 still have issues btw, so i'd better stick with KingKong
You don't dare oil or grease those sliders, dry lube only. Grease will have those jammed solid with dirt. The scraping noise is the slider channels already scored up, won't matter how many times you change slider plastics.
This review is absolutely top I must say ! All our answer of the S20 is here , thanks Wrong Way ! I think king song need to work on the tiny details like seals and some screws might come out in long term , otherwise a very very good design ! I do like this wheel 👍
oh no, the shaved Adam
It would be cool if you get to inspect a later production model to see if the design/build is still as bad as this one. I'm still looking forward to my S20 but I doubt I'll get rid of the Hero 🙂
I have the Sherman AND love it
Jakość wykonania masakra 🤦♂️ Adam dzięki za video, chyba jednak trzeba poczekać na kolejną wersję tego koła. 😐
Awesome video as ever Adam, thanks for that teardown. Just as an aside, turning the spring on the suspension doesn't adjust the stiffness of the spring, it just changes the preload so basically it makes the EUC sag less when you get on it. If you bottom out on the spring, no matter how much preload you add, you will still bottom out on it unless you change the coil for one with more resistance. Most shocks manufacturers recommend to keep the preload to a minimum. Cheers!
I heard somewhere that sag should initially be set to 15% of spring travel when static loaded with rider’s weight. This is adjusted by preloading the spring.
I mention this because it appears that most riders I’ve seen on YT aren’t properly setting up the suspension and are not experiencing the optimal performance.
Also, those slide-blocks should be Delron (sturdy plastic) and the slider-channels should not be aluminum. 😣
@@grb1969
Delrin or polyoxymethylene
The spring comes in 500#, 750# and 1000# . It's shipped with the 750.

No 2000lb springs? Asking for an American friend.
Of 1000lbs I can't find to buy! Does it exist for this damper? 1000lbs/3.00??

Hello to Serhii, whom I gave an advice to contact Adam! 😜
And thanks to Adam again. 🤘
BTW, Adam, ask Serhii to show you the screenshot I sent him specially for you. ☝️
Definitely popcorn worthy!
The suspension will always bind and wear like that being supported just from the back slider rails like it is.
Well, I have to comment, it is not the first wheel with smartBMS and cell monitoring, as well as temperature sensor.
Ninebot s2 and z10 have smartBMS with the same features.
Inmotion BMS have temp sensor inside, but for internal use (you as user can't see data from sensor in App).
Big thanks to you and Sergey for this video, sound of sliders moving.. it is the best :)
I know nothing about the internal components of an EUC, and because of that, I really appreciate your detailed analysis of what's going on in the inside of these things. I think you're doing a great service for everyone in the community. Thank you for your honest opinion and detailed analysis! And keep up the great content!
Dry lubricant like graphite might be a good choice for the sliders.
Would like to hear more about that. How resistant do you think the suspension can be to particles, salt and other elements by using the right lubricant?
@@supercurioTube I think it depends on how well they can keep sand, dirt, dust and water out of those slide tracks. If they cannot be perfectly sealed a dry lubricant like powdered graphite seems like it would be the best choice in almost any scenario.
Those channels are right next to the tire so they're going to be full of dirt instantly
Nice video!
Honestly I don’t see them improving the screws in the production version… why would they put in shitty screws in the first place?
They said they would.. they probably were just trying to get the preproduction out.
@@V1ncentVanBro its still not witchcraft to know that basic hex might not be the best idea wenn you need to tighten them down hard. If you pay that much for a wheel and don’t even get Torx screws that’s pretty sad.
you think an 80/80-14 or 80/90-14 scooter tire would fit? That's allegedly the tire dimension that fits the OG Sherman & EXN and they seem super grippy!
Tubeless and stiffer, so people are running them at lower PSI. Just thinking out loud.
-you are looking at this entirely the wrong way,,,,
-excellent.
-like the reverse poedal mod.
Интересно . Спасибо ! Сергею Привет ! )
The more complex you make a mechanical system the more points of failure you introduced.
I was kind of anticipating this level of 'engineering' when I saw the first renders.
I was worried they would squeeze the wheel together to fit the concept art (like that car Homer Simpson designed) and it appears they did just that.
Oh well, let's see what the Master delivers 😊
Great video btw ❤️ Truth 💪
Infinitely better built than your typical Gotway (Begode)
What's the new tyre?
Measurements on the side of the body, so that's it easier line up the pads
Oh man sliders really need to be like delrin or teflon slippery stuff. Also any dirt that gets in there will grind the aluminium away. I like the bearing idea, would survive dirt much better.
Same! I assumed that would be big teflon blocks. I can't understand why these would be rubber, aside from helping reducing the risk to bend metallic parts during crashes.
@@supercurioTube rubber helps absorbing sounds. Doesn't matter if the rest of suspension is rattling with all the slop in al moving parts. But I kind of expect sloppy china design with hard plastic sliders. Building your own linear actuators you put 3d printed sliding parts in an aluminium extrusion, works pretty good but these don't see dirt like outside vehicles open to the elements. Grease loves to gather sand and will hold it really good. Sandpaper effect on your sliding tube.
I am not able to remove the 8 screws that hold the pedals, my tools twist and the screws do not move. Were they glued with glue on the production models?
Any tips on how to remove them without breaking anything? I wish I could reverse the pedals.
Please PLEASE do a comparison between the 16X and 18XL, I'm having such a difficult time choosing between these two even regarding my usage needs, and you're the one whose recommendations and experiences I trust most!
Based on what I've seen elsewhere, the 16X is more nimble, has slightly more torque, and is probably better off-road, while the 18XL is better for road cruising, and has a marginally longer range due to the wider tire diameter (more distance covered per tire rotation). My first wheel was an 18XL, and I now have plans to get a 16X as well. The addiction is real!
@@ClokworkGremlin What qualities have you enjoyed with your 18XL, and what are you looking forward to in the 16X? Is your getting a new wheel just because you have such various needs as in cruising vs off-roading that can't really be met with just one wheel, is there something the 18XL hasn't amounted to in your off-roading style for example?
16x
@@slidersgliders5516 your 2 cents on the why? I already know the basic differences, looking for experience-based evaluations now
@@onnen-tipu if you already know the basics, my two cents isn't going to make your mind. Get a 🦅
so much for that smart BMS
How's Inmotion S1 review coming along?
Getting close!
I am just curious about Gotway's new Litech batteries, lets hope for a much safer battery pack than previous models.
Let's goooooo!
So what’s the best wheel in your opinion. I’m researching for one.
I was sold on this one. I still think I am.
But the battery should be rapped and I wish I could lube my suspension.
And also they need to get better bumper and kick Stan. I’m just saying it’s a lot of money to just break apart.
How many miles are on this wheel at the time of disassembly?
I think the stiffness is from an over-weight spring. I doubt its rating should be much more than 2x your rider weight. Seems KS sized it to the biggest possible rider. The fact that it compresses with its own weight is far better than the S18 was.
Great video Adam. We probably shouldn't be buying this Gotway clone 😉
👍👍👍👍👍
Very good disassembly Adam. I 100% agree with the screws going through controlboard. Its not veyr useful to have sealed box when you drill it and screw through that (especially from top) thats not really engineered. Your fuse comment aged well seeing that the fuse is not really the weakest point unfortunately.
Anyway that screwing of Shock spring changes the preload of spring. That mainly affects the ride height or the stiffness when fully rebound. You really dont change the suspension stiffness by this setting (or you do a little bit) but thats not really meant to do it this way. Changing for different spring is the correct method.
The suspension really looks bad. I am really disappointed
Is there a way of putting oil in those slider without disassembling the wheel?
Any lubricant here would just accumulate dirt and worsen the wear characteristics. Sad.
@@grb1969 exactly, maybe some dry graphite Lube but that's about it. Not a good design
There is no grease because there are plastic guides on suspension!!! And none of it is hidden from dirt or mud. Which can cause premature wearing...
I dont know... This is a pre-prod model, so how representative is this QC vs to what they will be releasing?I was really hoping that this wheel would be better, I was dead set on getting it but the poor range and the questionable overall quality makes me want to stay with the sure thing I have. LeaperKim should just build a suspension version of the Sherman, with the same range and quality.
I switched my deposit to the V12 high torque. The s20 just isn't there yet
Any hopes on Kingsong taking the feedback from you and other testers and implementing some fixes for the production build? Has that ever happened before? I love the design of this wheel so much, would instabuy if it was at least decent..
Hello my friend!! 🤙🏻
Good video!! 👍🏻
The tire that you have compared and put is that of an RS? a Sherman? Is it 20"?
You can see a lot of difference in diameter! Is it better? The same? Worse?
Thank you!👏🏻🤙🏻👍🏻🤗
One burned down on Hsiang channel. There is video of it exploded.
The first in the world!
Hey Adam and Community, I have a dilemma, I sold my Sherman last year (I regret it) now I want to buy new wheel, but I dont know what to get... Sherman Max looks good on paper, but cant find much info about on internet. S20 looks cool as hell, but the range that people have gotten is to low for my liking ( I weight 114kg with gear on) Inmotion v12 HT is on my mind as well.
I just want a wheel for commuting and weekend rides, I dont do jumps or any trail runs.
With given info what wheel would you get?
Same here. Sherman max would be a good choice
The V12 high-torque looks awesome, wider stronger rim, nice rounded knobby Tire, as well as the better motherboard.
The quality of ks s20 is horrific! Btw when I leave my euc when its turned for ~2 hrs is it bad for the wheel?
Sry iam shocked and i thought Kingsong = save and so on but now they are getting cheaper and cheaper to earn more money thats crazy, they are destroying his own reputation.
Hahah everyone on here is structural,mechanical, & electrical engineer... obviously 99% haven't ever heard of UHMW plastics and their applications...
Please tell me more, I actually found a few things in this video questionable
💯
@@CZcams_Zukz anything you put in those channels it's just going to collect dirt, once them aluminum channels are scored it won't matter what the plastic sliders are made of
It won't matter if you use uhmw on them sliders, once the aluminum channels are scored with dirt and sand it's all over
Mud is stickey stuckeys.. today
Ninebot has also smart BMS in 2018 🤣. Anyway sorry bro but ekolka made much better quality check video, YT competition is raising :-).
I was wondering if Ninebot did - yeah you’re right. It’s good if they make solid content then I won’t have to :p
@@mr_wrongway That sounds like gotway strategy
What's up with conflicting info on this wheel?
Kiedy sherman max? Waham się pomiędzy bull commander a veteran max, głównie, jeśli chodzi o jazdę pod górę długo.
Kinda disappointed with what I saw beneath the plastic on this machine. Kinda disappointed with the building process they did. Hopefully they improve it and I might buy one then.
You're trying so hard to hate on the S20 but it's just not working. :-)
Payola, alive and well in 2022 - except we're supposed to disclose it these days.
He's just being honest, I understand though how you feel as I was all about the s20 at first and no one could tell me otherwise. Now that I have seen how cheaply made the suspension is there's no way I'm forking out 3200 bucks for that. It's just not there yet
Me? :p
Not the greatest quality.
They making a lot of money on every unit but quality is so low. Shame and waste of money.
Maybe I'll start with an engineering class, before getting this wheel.. a tire change alone shouldn't be this complicated. I don't know why simple designs like the Regio wheel's case are not adopted.. step up your game, china.
HELL NO
After s20 fire now that 60a fuse is not so funny :(
Проскурка к ВронгВею поехал?

Quelle honte ! même les coulisses des tiroirs de ma commode sont mieux réalisés. Comment peut-on simplement imaginer un système aussi sommaire sur lequel repose toute la suspension qui est l'Argument de vente de cette roue. Et inutile de tenter de mettre de la graisse car les rails sont ouverts à la poussière et autres joyeusetés, du coup cela ne ferait que faire adhérer d'autant plus les particules qui provoqueraient un abrasion encore plus importante et quand on connait la dureté de l'aluminium et du plastique (plastique je n'ose même pas dire ce mot lol) on imagine le durée de vie d'un tel système.
La S 18 était mieux conçue... Pour oser faire du off road avec ça franchement faut être grand philosophe. Si c'est ça la roue du futur, avec en plus un déséquilibre d'au moins 5 ou 6 kg sur l'arrière pire que l'EX.N et ça pour 3300 € bon courage. Chooch dit qu'il en voudrait 15 comme elle ?! c'est sûr il doit en falloir autant pour rouler longtemps sans problème.
Quelle déception en effet. Ce design est pas seulement inadéquat, mais clairement absurde.
