Anyways, the motherboard for my V12 has just been handed over to FedEx. 

Will be replacing both the boards together with my dealer once it arrives. Fingers crossed. 

Hope it's gonna be ready for next week's track day.

That’s very cool 😎. Hope we get to see some video’s of the event on YouTube.

Super sad as I just spent hours installing my new board to my v12 and it failed, I worked meticulously installing it too.  I did notice after screwing in the mosfets I was getting conductivity on several screws, so I used the new screws provided, and reapplied the thermal ribbon and that solved that issue.  I turned the wheel on and heard a very light pop and the wheel balanced with no lcd screen for a minute… that was it.  When I turned it on again there is nothing. I will take it apart next week and diagnose the problem when I’m back in the studio. Super disappointed.

Its probably time to put this out.

Do not ride your V12 with a new board. There seems to be an issue with the new boards. There will be more information soon and your distributors will get to you too.

If a screw has conductivity with a mosfet, then you would remove the screw and check for continuity between tab of the mosfet and the heatsink. If there is no continuity then either an insulating washer wasn't used or the washer cracked. The video below gave the warning of over tightening the screws.

Timed stamped.

Wow, that is nuts. I hope you are wrong. Somehow, I have a feeling you are not.

I like this.  A lot !   (not)

No, absolutely no protection against static electricity. 
Handling sensitive electronic components on something similar 
to a kitchen table, walking around on a vinyl floor or similar 
with a plastic coating, this is really good for building static 
electricity that can fry any component or add damage that first 
appears when you lie with your head on the asphalt. 
This is DIY at its best.

Yes confirming what @rolis says right here.

As observed by multiple distributors worldwide, some of the replacement boards fail either by burning MOSFET or temporarily which leads to cutout. So far, each instance happened at low, walking speeds.

Inmotion is aware of the issue and working on a lead they identified but it is too early to confirm.

If you have such wheel and want to do something instead of simply waiting, a valid test so far has been to walk the wheel. Like @rolis documented, the failure doesn't necessarily happen quickly, therefore although it permits to recreate the issues sometimes it is not conclusive. Walking x km successfully with the wheel doesn't mean it passed and is safe to ride.

Please inform your distributor in case they are not aware. They should get in touch with Inmotion for further instructions. Inmotion hasn't been keeping distributors in the loop yet.

Message to distributors: I would recommend you wait before shipping wheels to customers after a board swap. If you really don't want to then walk the wheel for some time as the absolute bare minimum test, and inform customers of the ongoing issue and risk. Just like earlier, shipping wheels to customers puts them at risk of cutout, and the reseller to further shipping costs.

A very rough failure rate estimate averaging from the distributors I talked to is 10%:
Edit: talked to more distributors: should be less than 10%. Can't tell if widespread yet (possibly not)

Yes well aware, I adjusted this and checked three times each screw with a multimeter. I made sure there was complete isolation before installing. I know what I was doing as I used to build battery packs and ebikes, I was confident on my work…  I’ll find out what happened, and install my old board if everything checks out. Let’s see

The inmotion v12 are such pieces of shit amber turd left one on Johnny’s bed 🤣🤣

Yes, it's sad. The V12 should be such a slam dunk hit wheel. Who would need a Nikola or 16X when the V12 exists! But this issue, and they can't even get it fixed right

Amber is going to appeal.

Thanks for pinning the notice in the V12 warning thread BTW.

I'm sure everybody hates reading the call to not ride the wheels, it's dreadful for sure.
In this case however we don't have enough data yet do confirm that there's an upwards trend with cases. The upcoming 2 weeks will be critical to monitor, people receiving their wheel back from service and riding / trolleying them.

So far, it's entirely possible that only a few boards were defective and that was all, and we should be able to tell soon.
Between forums, connection with distributors, facebook, Telegram.. We have a fairly good monitoring system so stay tuned.

Does anyone know how the board/software issues will affect the HT? and/or does anyone have a HT that can give any insight on their experience?

Ht is that the v12 (heard’s turd ) edition 🤣

[Rawnei]

Just got the V12 back, gonna go out for a ride see if I can reach top speed! JK will walk it and maybe ride slow in the basement corridor for now.

All this mess is mainly about the new V12 HS boards. But there were some V12 HT issues, too.

How many % of riders are affected by each... too early to tell? I'm getting confused.

Double trouble: bitter, not just sour.

I am f5ing this thread with alarming regularity right now. Thank god its not a very popular topic in the grander scheme of things, or clickbait writers could make a mint off of me.

Meanwhile, now that the weather is nice I am riding this damn thing more than ever. 

[Bruce_dubby]

You and me both my friend. Just that I have the HT on pre-order and I just don't know if I should cancel.

First EUC? Absolutely cancel. Only get a V12 if you have the money to buy another wheel that is actually proven reliable, or if you feel like riding EUC is not dangerous enough/too boring and want random cutouts to make your experience more interesting.

I have been riding my v12 heavily for the past few weeks. Waiting to hear from ewheels about replacements is nearly maddening. They do answer when i bug them, but then never follow up. At this point like i have mentioned in other posts, i am just going to ride my wheel. Everyone got their damn money from me for this wheel, but none of the parties that cashed in even communicate out the bare min of what is going on. Thank god we have an active community or many of us would not even know what is happening. Anyway.. I spent the cash.. I am going to just try to enjoy the wheel and gear up as much as possible when riding in hopes to avoid any cutout or injury

@Bruce_dubby This is, sadly, the right answer. Nothing worse than not trusting the thing you ride. If you are a new rider and paid a lot of money, that makes it even worse. You don't want to sour yourself on the fantastic joy that EUCs are.

Maybe an RS HT?

It's depressing because the V12 ticks so many of the right boxes and is pretty much the ideal first wheel for so many people. I guess we have to wait a few more months for that? (Same for the V11 which seems to have quality troubles in the latest few production runs. Otherwise such a good entry if you don't want a mega performance wheel.)
