And what about owners that do not have any single issue?

how many ? What is the ratio ?

I don't think there's any way of knowing this because we don't know exactly what the issue is yet. We could theoretically all have the issue but it hasn't been triggered yet right?

For example I got my V12 yesterday and have ridden about 10 miles so far, hit a max speed of 30mph, the weather here is below freezing (20 degrees fahrenheit), and I weigh 225lbs. Didn't get a cutout but that doesn't mean it won't happen

Honestly I like this wheel too much to stop riding it lol so I'm gonna take the risk but will keep my eye on the forum and Inmotion social media to see if a recall or anything is initiated

Only Inmotion can get a sense of the ratio, we will not know that.

For a self-balancing vehicle, all cut-out leads to a crash.
20km/h is the speed at which @ThaBlackCobra destroyed his shoulder.

We need clarification from Inmotion.
Until then, I would suggest to each V12 owner who happen to own another proven wheel to ride the later.

Will keep riding my v10 which is 7500km without any single issue.

but can’t wait to receive the v12 😁

that sucks, guess i'll go back to the 16X for a few mos until we get more info on these. i had put about 150 mi on my V12 but its almost time to take a break for the winter anyway so i won't push my luck. thanks for the warning @conecones glad you're ok

I gotta say, recent postings of the V12 cutting out has made me flip my decision on purchasing the V12 back to an S20.

I think I’ll also send mine back and ask for refund, I don’t wanna end up in crutches.

For everyone's visibility, my V12 cut out after it was ridden 200km in total since I bought it two weeks before. My friend's V12 cut out after it was ridden 70km in total since he bought it to weeks before. And both of the wheels were totally dead since then.

@Clark Wong

Please note above comments and advise when possible, thank you.

Good to see the volumes.

I wonder if the ride test shown is the only one completed on the fully assembled vehicle or if each also runs some kind of programmatic stress test.

I imagine that running the motor forward/backwards in rapid sequence could simulate all sort of loads, by leveraging rotation inertia.

So, how do these things typically play out? Do I avoid using it? If so, can I be confident that there will be a point where I *can* be comfortable riding it again?

Might be recall, firmware update, only subset affected and identifiable by serial number, etc.... IM to respond with advice.

New models, first batches, first generation.... cars, S18, new products....early adopters, beta testers, guinea pigs....recurring pattern.

I believe this is happening to 2nd batch wheels... mine certainly was. but your point stands- not exactly time-tested!

[Namuhan]

Can anyone do a test on runningmat with v12? Drive it around 15-20kmh and have someone throw a log or something as a speed bump under it. Really scientific 

[Paul A]

A log thrown onto a treadmill at 20kph might come off at 20kph...

[lirva]

something with curbs. My BT and screen died also after hitting curb, dealer replaced the board but I haven't ridden much, since it's winter here.

For me myself, if @INMOTION SCV @Clark Wong have given us clarity on the root cause and the solution that makes sense to me, it is enough, and I will continue riding it.

Where did they give explanation please?

There is no explanation until now, so we are still waiting for it and hoping that they will announce on this group, since one of the Inmotion representation, which is @Clark Wong, has now joined this forum.

Since mine blew out walking it out of the garage and dropping off of a 2 inch lip, I’ll be walking it off of that same lip about 100 times before I ride it again  I had 90 miles on it when it blew.

Hello guys,

I used a V12 with over 800km on it, I encountered some speed bumps even at high speed (+50kph) it never failed. I'm not sure whats happening with some V12 but it is concerning, I'll be careful now until we know for sure what the issue is.

Control board firmware is 1.5.0.

In the past with Inmotion quality issue, @Jason McNeil posted here on the forum (V10f water issue on first batch) when it got investigated. Then a recall/rework went out once a fix had been put in place.

Depending on reseller action the customer either got a rework kit sent to them or the reseller did the rework. I got the impression most riders from the forum did the rework themselves. 

It was a extra/replacement silicon  off the seal between the 2 half's of the inner shell structure as first batch factory seal was too weak. 

Other brands has had different approaches. 

My suggestion is to Co tact your reseller. They have a kea account manager that assist the reseller and then the reseller communicate with their customers. The manufactory will not know who bought what to the same lever as the reseller. And I wouldn't relay on product registration for now. Now many manufactory has the infrastructure to handle end user commutation and service. That is why it is manufactor <=> reseller <=> customer and not direct link. There might be a news post here on forum at some point. This is how it works with all brands more or less.

Before my V12 dead, I also encountered speed bumps when I was at high speed, and no problems found. Somehow it died when it was ridden at 15-20kph, and of course it was not the only occasion I rode my V12 that slow.

I am curious, is your V12 from second or first batch?

[Djal]

seems that issues are mainly with second batch and 1.5.4 firmware no?

waiting for my 3rd batch next month

[supercurio]

I had a chat with my reseller and shared the state of things at the moment.

He said that Inmotion did not inform or alert him regarding V12 anything, and also gave valuable context:

Quote

Now more cases with all Inmotion models: many electronic components are not good quality including batteries BMS, with around 30 percents of last bach v10f models

Imagine a 30% rate of BMS failure on a model well established and in production since 2018, added well as unspecified but significant amount of electronics failure on all models.

Some might be linked to shortage and disruptions of the supply chain (poorly performing alternatives, grade B components or fake making it into the final product?). In all cases Inmotion has a lot of problems to solve.

I have to admit that my confidence in Inmotion for higher safety and reliability is down the drain.
For instance, I chose a Sherman because despite its popularity, this type of failure seems to simply not happen.
I still trust Inmotion design regarding battery safety however, since none of these 30% BMS failure ended in a fire.

I encourage everyone else with a pre-order to inquiry their dealer in order to increase awareness and require Inmotion to increase transparency on the issue.
