Inmotion V12 HS Creaking Noise

[TehTEh]

Hey guys, recently my V12 has been making this weird “plasticy” creaking noise. It’s coming from the right side of the euc. The noise occurs whenever my weight is being adjusted on the right pedal or whenever I’m accelerating hard. I know that the sound isn’t caused by the pedal because I’ve swapped them and it still occurs. I’ve also taken them off completely and used the trolley to accelerate the wheel quickly and the sound still occurs. Does anyone have any suggestions? Thank you.

Is the noise happening when you don't touch wheel sides while ridding also? (Stand only on pedals themselves - don't touch euc plastic..) You said trolleying it around it makes same sound also - so i don't have an idea.. Only valve stem could be hitting inner shell.. (Doh clicks happen way to often/fast to be a valve stem..)

Cable tie inside motor?  Crazy idea.. But they use them to tie down wiring... (Doh again clicks are way to loud to be that.)

Cracked shell..

If it's a plastic noise on one side, check if the valve touches several places on the internal shell. The noise is absent when the valve passes outside the hull.

+1.

I would say this is most likely the cause, if the valve stem is on the right side of the wheel. If the valve stem is indeed located on the right side, can you post a picture of the valve stem sticking out from the rim?

However, on my V12 (HS), the valve stem is located on the left side of the wheel.

The valve stem is located on the left side of the wheel and is clear from hitting anything inside the wheel. At this point I believe its most likely a cracked shell, although I couldn't find any cracks when dissembling it.

Yes, the noise still occurs without touching the wheels sides. It's so strange, I would also like to note that prior to the noise occurring, when disassembling the wheel for the first time, a lot of pieces of plastic from inside the wheel have broken off  and fallen out during disassembly.

Also if sound started to happen suddenly out of nowhere - it can't be valve then.. Ofc if user didn't change tire/tube before it started to happen.

Looking from that viewpoint - one day riding = everything fine. Next day somehow valve stem has shifted??? Not logical at all.

Better bet is having a tree branch stuck in wheel well..

Well, you would be probably right, if the original inner tube was never changed before, or a zero degree bent valve inner tube was used as a replacement.

However, I had an exact scenario happened to me. And it sounded just like that on my V12 (HS).

I changed my inner tube to a 45 degrees bent valve inner tube. At first, there weren't any noise. Then after a period of time, the valve stem started to rubbed.

My inner tube no longer rubbed now. My adhoc solution was to rotate the inner tube circumferentially to the direction that would not allow the valve stem to stick out so much. It worked like like a charm.

All the owner has to do is to shine a flashlight in the wheel well, and he will have his answer.

True - but user didn't mention about changing, or doing any of that.  

I also had 45 degree valve, which i exchanged to 90 degree (In my case it still clears wheel well, also easier to pump up tire.) 

I also had a clicking noise that happened once per wheel circle. In my case it wasn't valve cover, but stem itself. Somehow when tire touched ground it would bend under pressure of weight and when left ground it would "spring" back into position hitting rim hole where the stem comes out of rim. Yes 1-2mm gap around valve stem was enough space to make clicking noise. And also coming from one side - which side i had valve stem installed.. As i would lean that way it would make clicking noise as clock work.. But riding backwards/forwards - no noise. Only while turning one way and ridding forwards..

My fix was adding heat shrink around valve stem... To fill the gap of rim hole.

I think you answered your own questions Captain, cheers.

Broken shell, stuff needs to be fixed/replaced.. Do some DIY fixing or buy new shell.

But still, that sound and being so aggressive.. It really happens exactly the same while trolleying it around? Only thing moving is motor. So something to do with it.

Isn't there any chance of shell being so broken that it scrapes tire? Or any plastic in wheel well?

 

Turn the EUC upside down and shine light in there..

 The sound only occurs when using the trolley aggressively (and instead of multiple clicks its just one) , like pushing the wheel forward very quickly. I'll soon disassemble the wheel again and check for any cracks in the plastic.

 I don't think there could be any plastic scrapping the tire, Ill check for plastic in the wheel well. What I think it could be is the motor blocks shifting in the chase due to a cracked plastic shell.

 Thank you for your help guys!

Motor blocks??

Maybe pedal "L" brackets are loose? (Only thing that holds everything onto motor itself.) EUC Shell are connected to them.. Same for pedals.. As weight shifts all the time - it makes noise. (Makes sense also - if only one bracket being lose it makes that plasticky noise as whole wheel case "twists".)

My one pedal often cracks, when i step on it. But only that one moment as i step on.

My guess it's a bent pedal rod. When that happens pedals tend to creak when you shift your weight. 

Try one foot only and do the same movement. Which side creaks? Check that side.

 ISSUE RESOLVED.

 Turns out that the "L blocks" connected to the axle weren't aligned perfectly, I resolved this by removing both bolts, setting the motor on two even blocks, and putting both bolts back in making sure that they're even.

 Thank you all for your help and feedback!

  So i was almost right.. Going down the rabbit hole sometimes pays off. 

FYI: Don't forget to recalibrate your wheel (In app where you put wheel in level position, etc..) - as you messed with pedal "L" hangers. Meaning if you had pedals set at 0 degree, now they may be messed up.. By logic one should recalibrate their wheel each time they have messed with pedal hangers.

Good to hear that the problem is resolved.

Just curious, what was hitting the shell?

Also, I don't understand how the pedal hangers were not aligned. The pedal hangers slides onto the axle and is positioned circumferentially by a keyway and key. If the bolt was properly tightened, the pedal hangers would have been locked in place correctly.
