This is just physics that comes with a self balancing device. You just made a positive feedback loop instead of negative - result is instability. You can possibly get the same issue in any other wheel by swapping the 2 phases. Explanation of what happens is that wheel frame sees tilt and wants to correct but the motor rotates in opposite direction so the correction has basically wrong sign and adds to the tilt. The problem with V12 is that you can easily mount the motor reversed. Other thing is that never ever turn on the wheel while motor is not fully assembled to the frame. Always take out the battery connection first to be "safe". If you accidentally turn on the wheel with motor only partially screwed your wheel will rattle and self-destruct in a matter of seconds. Dont ask me how i know.
Thanks for the content, Chooch. You're such a real person - nothing fake, just you. We appreciate the hard lessons being taught via someone else's experience. I hope everything is ultimately alright. I'd be naming that wheel "Taz"; like, it's the Tasmanian Devil. lol
Glad I watched this video so I don’t make the same mistake lol but I plan on getting a V12 after they fix the cut out issues
Any word if the HT and HS models going to have the cutouts fixed?
is it fixed ?
Is the tire tread not directional, such that when you flip the motor you also have to reverse install the tire? Good info on the orientation, thank you,
This is the nature of brushless motors, swap any two of the three phase wires and the motor will run in the opposite direction.
An easy fix for this is color coded heat shrink.
That's literally a FW bug. If it is aware of which side is which, then it should be DAMN aware of when it's installed incorrectly.
This is why open source. Then someone could simply fix the bug and people wouldn't get hurt no mo - and they should also key it so there's no way you can put it in wrong.
EDIT: You aren't wrong bro, it's a really really really DUMB bug. You should attempt to file *mechanical* bugs too, so definitely file a CAN INSTALL MOTOR WRONG DIRECTION SUCCESSFULLY bug if you can file the first bug. If there's no option, put it in the description of the firmware bug because firmware is just programmable hardware so you can play dumb and dump a bunch of additional info in there they have to read if they open the bug report. Things like "you wouldn't have to fix a bug that wouldn't exist if the motor couldn't be installed backwards". FW engineers love seeing that stuff :-) it makes it not their problem and more people get engaged because nobody wants to do it. :-)
(used to be part of my job, back when)
Transport Mode. From now on, I must be positively sure I put my wheel in transport mode every time I put it in the car. Seeing what can happen when it suddenly turns on opened my eyes. 😳
That was pretty intense Chooch there should be a keyway opening on one side so it can only go together one way & not the other, as much as I like Inmotion, that's an engineering oversight! That should be addressed immediately! one other way is before ripping everything down, mark everything on one side with a simple L or R Depending on which side you start on, I realize you've worked on your own wheels for years & that knowledge can also be a false/positive, especially with the new technology in these Euc's leaves me to believe there's a different technique to work on them as well, and to stand along side you on the issue, the manufacturer should also put markings on their parts so the orientation cant be confused from one side or the other. One other thing I do when ripping anything apart is taking pictures of everything and reference these pictures when reassembling. Good luck Chooch in protecting your home & your 🐱
Well, that was funny actually. Good to know though. I think I would have taken it outside the second time. This really could have hurt someone. Thanks for sharing.
Just took my v12 apart yesterday 😳 thanks for the heads up
FROM TIMES SQUARE NEW YORK CITY. !!!!! YOU GO BABY BOY 1 LOVE & PEACE
Glad i skipped the V12, just put my deposit on an S20, i trust kingsong to make it right with any problems with 1st batch. Yea, i would make sure you put the wheel back in the way you took it out. Not that difficult 🤣
I find it hard to believe that the permutation of the phase wires does not matter on any other wheel. I find it more likely you have plugged it in in a way that happens to work right every single time previous to this.
The order the phase wires are plugged in determine the motor direction. The controller has no way of knowing if you've plugged it in correctly, this is true for all brushless motors with or without hall sensor. If you plug the cables in a different order than what the controller was configured with this will happen. I really don't think Begode would have developed some technology that would allow the wheel to automatically sense the new configuration, you've probably just been really lucky.
he is saying he physically had the motor turned 180 degrees not the phase wires. so technically you can install the motor backwards as long as you swap the phases around
@Blox117 sensorless is used by all wheels beyond a certain speed. The hall sensor is only useful when going really slow since the back emf isn't strong enough for the controller to detect the motor position at such low speeds. Regardless of this, the motor is configured to have the phases connected in a certain way, it has no way of knowing if you connect it incorrectly and will try to spin the motor as usual, which will then end catastrophically, as shown.
@@lukasbremberg4365 he connected it correctly he just had the motor turned around.
also, i was referring to it being purely sensorless mode. or at least that is what an article claimed about the s20
@@Blox117 ok, i stopped watching after that part lol. Turning the motor the wrong way would have the same effect att plugging the cables in the wrong order.
Also, I can 100% guarantee you that no self balancing wheel existing today or in the coming years will be purely sensorless. Sensorless simply does not work below a few mph, it would not be able to balance you at low speeds. Maybe it's using something else than a hall sensor, but the regardless, with the brushless motor technology available today, some sort of extra sensor is necessary to detect motor position at low speed.
Consider most e-scooters, you have to kick and get some speed before the motor can start, this is because they have a sensorless motor which is unable to detect motor position at standstill or low speed.
@@lukasbremberg4365 i know, i have a programmable vesc and in pure sensorless at zero RPM the motor cogs up badly. i need to be above around 5 mph before i can take off smoothly
WTF moment 4:45 😯. Launched like a cannonball. TY for the tip an example
Love ya man, thanks for taking the licks of this new tech so we don't have to 💪
Damn that's a down side of a touch screen I never thought of. If you can power up your wheel while your working on it can make a bad day a nightmare. Thanks for the PSA! A trick I use on the motor is. I put a peace of tape on the right or left side of the motor when you pull the motor and mark the side with a R or L. Then remove the tape as you put it back in. Works like a charm 👍 ride on!
Good to know and your right a beginner like me would take pics and label but the tape idea is great. Coming from a Onewheel we expect Future Motion to be a pain and specific. Haha. Thanks man.
what is your problem you couldn't remember where and how to connect the cables! of course you would not only break the wheelbarrow! at least in the direction of the tread on the tire could think !!!
Glad you uploaded this. Not buying a inmotion v12 anymore!
I hate when touch buttons are on things that make no sense. Esp outdoor stuff.
Love your videos man, the fact that you are real and not try to pretend that you know it all.
I believe that you are becoming number one in the EUC world on more than one level.
Keep up the excellent work !!
Appreciate that Carlos!
damn...good lord..
This must be Wroooong Way's influence.
Inmotion needs to a repair video, tear down and re-esemble
@@bepriceless it doesn't have a re-esemble.
Good of you too share this. Probably saved a lot of people the mental anguish of having to deal with something like that. Not to mention needless court costs from any variety of situations related to it.
Glad your cat didn't witness that.
Me too man, she’s so innocent too would have been terrible. Her name is dirtbike lol! I have had her for 13 years found her as a kitten in my old chest I used as a tool box and she has hung out ever since. She’s probly honestly smart enough to avoid the area when I start doin euc stuff XD. Parts always flying and chaos, they know what’s up.
Did you already go through 2 tires on your V12?
Chooch what an amazing info! This will be a big precaution in helping someone disassemble and assembling back any EUC. What happens if it run you over? That can be a huge injury.
Screwed, glued and tattooed 😁 thanks for the heads up.
Who does mechanics with a coat on.... 🤣
What's the deal with wires on both sides of the motor??? On every other wheel, Sherman included, the wires are only on one side. That makes it hard to reinstall the motor backwards.
Thanks for real Video💪🏻
Hold on if you reverse the wheel the rotation will be the wrong way. That means when you lean it back it will go forward, the forward motion will make it tilt back even more and off it will go. I mark an arrow on the hub motor for rotation going forward. The reason I put the arrow is the frustration you get when you fit a new tyre with the rotation the wrong way. Sorry about your problems here chooch, at least it still works.
Such an awesome video bro
Why did you take it off to begin with?
Wild horses! Crazy inmotion
Impossible to put the motor in backwards on a Gotway with the motor wires only on one side.
Helpful video! It is quite sobering and a reminder of how much in its infancy the manufacturing on these things still are. Hopefully your video helps OEMs consider these sorts of things, as maintenance still feels quite daunting. What's that gorgeous bumper on your v12, man?
Hey chooch! Started watching your channel a lot. Have a deposit on the s20. What’s your opinion on me learning on that wheel as a first wheel coming from one wheel board experience electric bicycle experience and athletic background. Especially if I take it really slow
That's what I'm gona do. Just take it easy. Go to a school where they have football field so you can ride on the short grass and hold onto the fence if you are unstable..
Your gonna drop it a lot I recommend something cheaper to learn
You are going to fall. It's a viscous learning curve. Learn to go walking speed. Twist back and forth if you feel you are going to fall. At slow speeds. Wear full protection. Great sport but the falls can be very hard.
It's going ng to be way too heavy to start. Please cover in foam for the first month. You probably want to start on something that's about half of the weight
Wrecked my 16X twice hard when learning. Others are right you should start small, I couldn't imagine having a s20 or a veteran Sherman as my first wheel, it took me around 40 hours to get fairly start to get used to it. I just put my deposit down for an S20, screw it, ill take a 1st batch, i want it and you only live once. My 16X has been almost flawless, i trust kingsong to make any problems right with it.
How could someone still hate Gotway after seeing this.
DO YOUR THING 1
Good to know👍
I wish I would have found this before crashing my V12HT into a wall and breaking the top piece.
I am sorry buddy, but that spinning was hilarious😁
Keep ridding them dude🤘
hey! question about the rgb lights in the v12, mine play animations in reverse, is there is any connector for the side ones that could be flipped? thanks
whenever you take something apart, it's good to mark the way things were matched up and oriented, take photos vids make notes etc. use zip lock bags to organize the nuts and bolts
shouldn't use red locktite on aluminum stuff, the blue is good enough, I use the purple on aluminum too.
I am a very caring atheist that considers safety paramount, and have had to be very careful in dangerous situations even involving saving even complete strangers from harm's ways.
Please be safe and be tomorrow.
I can calibrate V8F in the app also so I quess it is the same problem :). But the controller is on the side so it is probably impossible to do it wrong because the cables will be on the wrong side :).
yea its a common mistake when people replace their motor. You only won't learn this until you make the mistake yourself. I burnt up my floor from my sherman spinning out. it took me a whole day through emails and facebook. Its funny watching someone else make the same mistake.
Sorry that happened but think how much you have helped others. Your always on point brother. And you keep it real. You are appreciated.
You should actually do a full tire swap how to.
How to waterproof an EUC.
How to maintain an EUC.
Videos like these would be greatly appreciated.
Do what others haven't. And even if they have? I don't where they are. But I do know where you are because I am a member.
Food for thought.
Nuff Said.
Dude that was exciting. Made me jump like a scarry movie. Boom!! Sucks but thank you for letting us see that stuff. Someone had to. And yes I like the ability to work on my RS. Pretty easy. Although I still can't get my RGB's or taillight to work. Headlight no problem, RS logo even lights up. But no tail or pretty colors. Whatcha think?
I wish I found this video first. I just sliced up my leg and nearly broke my hand because of this. With my v12ht
@chooch tech are you worried about the mosfets in the v12 being rated for 100v? You ride the bejesus out of all your wheels and I'd selfishly hate to see a gap in content from an injury caused be potentially out of spec mosfets. Our gotways have higher voltage mosfets on them to give some buffer.
The shell was put on backwards! Always mark your rim and tire with arrows or something to indicate both rim and shell side matches up.
Odd question - are you able to clamp the wheel housing to the bench upside down so it isn't rolling all over the place when installing?
I didn't see anything that completely precluded it, but in any case with a couple 2x4's I could just clamp the wheel itself so it doesn't roll around while I'm dicking with it lol I thought you were gonna lose a finger for a second there. That shit HURTS...
EDIT: Again, most people don't know how powerful these things are. I almost put a hole in my wall getting the V10F out of the box when I accidentally hit the on button (it's right on top and blends right in)...lol
In the RC world you always mark the wires before disconnecting them for the same reason.
REALLY confused as to why if you took it off the stand if KNEW or even anticipated it would startup like that. Seems pretty foolish to me. Also, good practice to take pictures and put things back together EXACTLY how they came apart no matter the brand. Doing so practically eliminates the possibility of this and most incidents from happening in the first place.
What's wild is that I watched this video before disassembling to change my tube. (Flat in less than 3km of use thanks to gnarly burr where valve stem hole was drilled) Yet I STILL installed the motor backwards. Thankfully I was sitting behind the wheel when it launched into my wall/and a few other items. I had totally forgot this video when putting on the front cover. Caught my finger in there and broke the tip. Lesson learned twice.
Thank you for the unheeded warning Chooch!
is the correct orientation like, the tire valve should be on the left side if you have the EUC facing the same way as you? (like riding position)
is this correct? that's what I remember but now I have it disassembled and seeing this just want to make sure I'm right lol
This literally happened to me. My problem was I put the tube in backwards so I aligned the valve stem with the case when it was initially wrong to begin with. The wheel got pretty messed up and I literally couldn’t turn it off. Once I put it in transport mode I was able to turn it off. I wish I had started with it in transport mode, none of this would have happened.
Hi! What tire on your v12? Looks great 👍 where I can take same?)
Chao yang 16x3.0
Ewheels or if they don’t have it revrides should
It's the CY H-666 in 16x3.0. Not difficult to find in Europe or order from china.
The 18” is another story tho.
You could probably put blue tape on the inside on the right wires and then put some on the right side in the inside housing on top. It would signify the orientation every time since the blue tape is on the right motorwires matching on the blue tape in the top. Probably would be easier to do for frequent maintenances. (Blue tape was just an example as you can use any tape.) Im probably gonna do this when I buy one very soon.
Thanks for sharing this. Very important and super helpful. Stay Above the Wheel.
Im bleeding from the same part from my hand for the same reason.Stupid me.
I'm making paraglider winch with hub motor wheel, I had mine suddenly go to full speed when I was trying to program it, the thing took off across the room, kept spinning into the wall like a buzz saw, it was like something out of a james bond movie. These things have the potential to unleash a lot of energy quickly.
That was hilarious when you say if you like screwing inmotion got on that lol..thanks for being so real Bro my respect 🙏
Excellent video mate, thank the Lord your lovely cat wasn't "helping" you with the filming that day.
Sorry dude but you're one of the funniest videos. I've ever seen on the electric unicycles love you brother but this s*** is too funny 😂 It's Catastrophic 😂 .
hello chooch... Isnt the one, Ive loose my s18 like that, same thing, but I didnt realize at time that the motor was inverted, but the wheel flies on the room, if this video come out before may I didnt loose my s18, my batteries was fries on the process so sad
Did you remove the motor to fix the rim? I and trying to remove the motor but the screw for the axle is soooo tight it won't budge. I already stripped a screw on one side and I did exactly what the instructional video said to do.
u r the best ! waiting on my v12 , glad i watched it before i received the wheel!
Maybe when you first get the tire out maybe use a sharpie to mark a forward arrow on the part of the tire that's not visible.
question, so if you put it on backwards.. but can it happen if you put the wires in wrong?
I’m sorry chooch you make it look funny 😂 I have the v12ht thanks for the info
that with the wheel write will try to tell the English language no aonia but I can translate
me ha pasado y ahora tengo miedo de encenderla, llevo 10 minutos mirandola
Seeing this after i did the same thing. Someone on facebook brought this video to my attention and its how i knew it was backwards lol
looks like it needs some snow tracks - Darpa got a nice track that turns into tire - still having problems with that tire - just don't bite the wires and see taught us something without biting the wires
Im putting back on the case today. Pray I don't pinch the cables.
Send it back let them fix for u.dont trust aw forget it I thought of getting it.now forget it thanks for showing us this
What type of new tire did you install chooch?
Were you able to find an off-road tire that would fit?
Thanks for sharing. Big satefy issue for sure.
13:15 is literally me. Took all pictures of every piece I took off
And you have a Swedish Fjallraven jacket…I had one in 1979 when I was living in Norway. Chooch…you are clearly a man of good taste 👍
Good taste as well lad! Yes this is the Greenland jacket with the hood that zips into the collar and you wax it for waterproofing. It’s the same as the old ones. Should have it a lifetime. Fjallraven clothes are the best, worth the price.
Oh my, thank god you didn't get hurt! Or burn anything!
Awesome warning and safety info Chooch man! Thanks!!
Just got mine and the torque melted my carpet!
Why don’t you lay it on its side and slide the wheel in that way.
I used to fix laptops, they never ran into the wall
OH HELL YEAH. This wheel is great . True STORY
How do u use this sound? Its not the standard sound wave
gosh, inmotion should have fail safes against that.
Happened to a friend’s v11 too.
Why you wearing gloves?
Thanks for the lesson
Thx man
4:47 is the money shot. Holy cow. Thanks for making this video man!
3 phase motors would always do that unless the board calibrated on startup(uncommon) what is normal in manufacturing is having the connectors color coded or even better keyed connector so that they can only be installed one way. Great job I’m about to pull the trigger on this wheel thanks to you. 👊🏽
Id really love to get into EUCs and had my heart set on getting a v12, but the prospect of doing any teardown maintenance on the wheel just puts me right off.... Tearing down my onewheel for my first tire change was stressful enough last week
Its not bad on begodes, I have one begode with all the bolts removed and I can undo a ratchet strap and change tires. Begode is easy to work on
I just installed a new motor and new controller board for my Begode RS HT. plugged everything in and when i turn it on it takes off just like in this video, lunges backwards. any thoughts on what is causing it?
Motor wires reversed the blue is where the green should be
@@choochtech i had thought that earlier but was afraid to try it lol. tired of it running away on me
@@jeffreyscissorhandz hold it up in the air firmly outside and keep the family jewels safe. I almost had one burn out on my dinga ling sitting down trying to exactly what you doing. Be safe, I’m serious!🤣🤣🤣🤣
@@choochtech lolllll
FYI i have them from left to right yellow, blue, green, which ive seen as the correct way in various videos. could my cables be colored incorrectly
@@jeffreyscissorhandz nah, very unlikely. Turn the motor around and plug everything back in the same way it is now just with the whole motor turned around
