I have found something not mentioned here that has finally solved my wobble. The shiny silver head bolt which the stem sits on has a small hex bolt on the front of it. You can just see it when your stem is folded down. This nut is the key to fixing the wobble. Just screw it out a bit and then put the stem and clamps back. It will improve once you turn it out sufficiently. Just trial and error until you get it right. I found that after a few rides the bolt would creep back in and the wobble would come again. I didn't think loctite would last so I found a small washer and put that inbetween. It can't move now and I am finally free of the dreaded wobble!
Locite 648. That's what it's for, any engineer will tell you this, you can remove the bearing at a later date when it fails and scrape it away then reapply with a new bearing.
They definitely didn’t fix the wobble. The stem is upgraded but the wobble is still there. I have the new 2021 mantis pro se. my stem is tight but the wobble is definitely there and it’s gotten a little worse. Thanks for the tips I will definitely be taking it apart right now and trying that thanks 💯
Go to an engineering shop and ask for shim steel, it's available in different sizes and will last a lot longer than plastic film, I would say that this could be classed as a warranty claim because clearly the bearing housing has been machined to the wrong size, the bearing should be a press fit.
I dont want to be too bold with my claims but this is already a fix for the bolt breaking. As soon as the bottom of the folding piece cannot move anymore inside the tube (what I achived with wrapping in cling foil to fill the gap) there will be no more Stress on the bolt and it will not break. There is an aftermarket folding piece that is thicker and longer but it essentially achives the same thing.
@@ralfhalbknapp1104 Definitely, you are absolutely right, I will do the same. Yet a lot of say main bolt requires a sleeve so that main bolt dont have any movement inside. Wonder if newer models updated to stronger bolts or improved the design of it a big. Also have you waterproofed your Mantis?
@@TheChazas my Model (that Was still Version 1) already has the stronger bolt. However a tighter sitting folding piece is in the newest Versions of Mantis I think and this will help.

The reinforced stem clamp 3 holes made by Kaabo have 2 parts one bigger and more long but the another one is 0.5mm more loose I don’t know how to fit it
This is a problem on many of these scooters after time just with the power these things have the rider puts alot of force on those handlebars. All that force is focused on that stem and bearing area. It's quite possible over time the bearing seat can become ovalised thus creating slop in that area. That whole area needs to be engineered alot stranger
Would a different larger outside diameter bearing help and is it from the bracket diameter has widened from stretching? And, how many kilometers have you done on your Mantis?
Honestly it still runs on the thick plastic bag foil centered Version and still works. I dont exactly know however what you mean that i should do with the nickel strips (given that i had them and a spot welder).
Hallo, bei 5:45 wie viele schrauben hast du da drinnen? Ich sehe gerade das ich beim Zero 10X nur 2 verbaut habe. Kannst du mir die Maße evtl. durchgeben von dem Modul wo die stange montiert wird? Also der höcker bei 5:45 ich möchte gerne wissen ob das der selbe ist wie beim Zero 10X. Weil die Stange beim Mantis dicker ist, und dadurch stabiler ist und nur aus einem Teil besteht. Und ich gerne dann beim Zero 10X die Mantis Stange installieren wenn das der selbe ist. Vielen dank :) Ich habe mir beim Zero 10X eine Dicke Schelle gekauft, leider kann ich hier keine Bilder posten vielleicht passt die ja im Mantis auch. Evtl. tauschen wir uns in Whatsapp aus.
Hi, ich habe M3x6 Zylinderkopf Schrauben verwendet - Edelstahl. 2 Schrauben sollten aber auch ok sein. Ich bin mir nur nicht sicher ob die Mantis Teile beim Zero passen, ich vermute eher nicht leider. Das Modul auf dem die Stange montiert ist (weiß den deutschen Namen jetzt auch nicht) ist jedenfalls mal je nach Version 16 oder 16,5mm breit oben und unten etwa 19,5mm beim zylindrische Teil. Du kannst mich gerne kontaktieren, am Besten mal über Facebook Messenger - dann muss ich hier nicht meine Nummer posten ;-)
Since the problem on yours is being caused by parts that don’t fit, was it wobbly from day one? I would think this collar being too small would be be the cause for those who noticed wobbling at the beginning rather than after wear and tear?
It was less wobble from the beginning but there was a less wobble and got more. Actually i had many different wobbly parts adding up, this is why i made the video. There is the loose hinge and bolt, the loose bearings and loose loose screws connecting the steering part to the lower deck.
Michael Sha has a folding piece that extends longer to the bottom and is a little thicker, this will work to eliminate the play and prevent the bolt from wearing and breaking. I think new Stock Mantis have also a solution in play. An addon plastic bolt sleeve that is also sold will NOT work as the bolt would still break between the bottom of the folding piece and the sleeve, so there would be no improvement.
I can tell you but it would not help you as the correct number is dependent on the motor used. P2 is used by the controller to measure the speed and display it correctly on the throttle so if you measure with gps and set P2 to the best possible number where gps and display speed align best you are fine
@@ralfhalbknapp1104 Thank you for tour response. In my case I had set to 30, now i changed to 20 and it runs to 45 km/h I will meassure it with the gps
Ich bin aus AT/Wien. In der ersten Version kann man den Arm/Hals in dem die Lager sitzen noch tauschen, in späteren Versionen ist das fix mit dem Batterie Teil verbunden. Mittlerweile würde ich aber eben den Weg gehen die Lager einfach einzukleben und fertig.
Not much force needed on mine, it slipped out easily (which is actually bad, it should be hard to pull out). If it sticks there really bad i would question your intention why you want to remove it. If you have a new and fixed version the folding lower bracket has a tight fit and stays in place. If you really want to pull it out i recommend to re-attach the handlebar stem and use it as a lever (fold a bit, put something like a wooden block under the half folded stem and then fold the handlebar stem even more - therefore pulling the folding piece out. But again - only do that if you need to!
With one of your wobbling issues you said you fixed it with screws on the deck? I think I have a cleaner solution so you don't have to hack up your mantis... If interested anybody comment on my message here and I could guide you through stiffening up the mounting point from the deck and neck marriage!
thank you! _ I test rode the Kaboo Mantis and this is why I didn't buy it ...yet - far too much wobble on the stem - and the Wolf's too heavy for me -I emailed them directly info@kaaboph.com to see if they had addressed it and showed your video (i hope that's ok :)0 awaiting their reply...
I talked to Kreo Motors 1 of the USA Kaabo dealers, they said there is a new model coming out soon that should be under a Wolf Warrior and similar to the Mantis. I THINK they will have improved it and fixed this issue, but we will have to find out for sure when it comes out.
Menuda tontería. De verdad te crees que esa es la causa de que parta el tornillo? Y de verdad te crees que así arreglas la holgura. La holgura no está ahí. Esta en la cabeza del tornillo en la zona por donde entra que tiene juego. Y al ir vacío por dentro hace mucha tensión y puede partir.
I will make a better video on the causes of the bolt breaking, this one was more about why the stem wobbles. And i will tell why i think that your sleeve is not a good solution ;-)

Interesting, hopefully Kaabo will sort out these QC issues soon, one of reasons why I have held off buying one.
Thank you Arnold!!! Now get to da Choppa!!!!
He will be back.

I got the new one Mantis10 V2 a month ago and I will confirm that this is no longer an issue
@@mrnobody2589 I just got my V2 today very carefully assembled and still have a wobble. Have contacted them but no answer yet.
lol I kept thinking he was going to use aluminum foil and then I saw the plastic! Different terms here I suppose. Great video!
Go to an engineering shop and ask for shim steel, it's available in different sizes and will last a lot longer than plastic film, I would say that this could be classed as a warranty claim because clearly the bearing housing has been machined to the wrong size, the bearing should be a press fit.
How did you tighter the stem to the base? That’s where mine is very loose, but I can’t find the screws
Did you find a solution?
How to fix or prevent famous Mantis stem breaking off. A guide on that part would be amazing. Also a waterproofing video.

These sleeve pieces will NOT help. Please please dont use a sleeve. This will still cause the bolt to break between the folding Part and the sleeve.
@@ralfhalbknapp1104 Good to hear, thank you.
So far had any other issues with the scooter? And again have you done any waterproofing to it?
If you have a lose bearing use Loc-tite bearing loc.
My problem is the stem clamp wont tighten enough. That's where it's wobbling. It's not a lower end problem. Kaabo Mantis 10 V2. Any ideas?

I'm gonna try that bag trick. It seems safer than the screws option.

I've always been a little MacGyver and still am to this day... My Solutions make you think.... "why didn't I think of that, genius!"
how long is the main bolt for the stem?
Would a different larger outside diameter bearing help and is it from the bracket diameter has widened from stretching? And, how many kilometers have you done on your Mantis?
What you could do us use 0.5 tick nickle strips and spot weld 4x pieces in a cross like pattern and that should evenly make the bearing fit
Honestly it still runs on the thick plastic bag foil centered Version and still works. I dont exactly know however what you mean that i should do with the nickel strips (given that i had them and a spot welder).

Can u adjust the stem if its to tight when u turn left and right??
yes, you need to loose that wheel with "teeth"
Mate do you know the specs / dimension of the bearings? Thanks Ralf!
Sorry, I don't know them by hard. I recommend checking with a local reseller - they typically have them in store.
Micrometer handy?

ralf halbknapp I see, thank you.
All these thing fixed with the new mantis10 V2
As i konw most of that was fixed but all in all there are so many revisions now that i cant tell which version fixed what.
There is a replacement for bolt sleeve. Do you think it will work?

An addon plastic bolt sleeve that is also sold will NOT work as the bolt would still break between the bottom of the folding piece and the sleeve, so there would be no improvement.
I just bought this model and i would like to know wich number do you have on parameter P2 (motor magnetic pole setting).

How did you remove the folding lower bracket once you got the bolt out? Sheer force? I’m close to blowing my back out here

Lmfao. Thats crazy.
Zero10x is a better scooter 300 miles and going strong
You would not say that if your Zero had Wobble. Its really down to the individual Unit and time of purchase.
Buy bearing glue!!!!
Very good tip, I didnt even know there Was such a thing as that and I will buy and use it for next time!
Defective... design. 😪
