jimjam.nyc Posted May 10, 2022 Share Posted May 10, 2022 Nice to see some communication on this! I am looking forward to going through the process of finally trusting my v12. I do ride mine often right now, but never fully trust it. So my fingers are crossed by July will have new board in hand! I will say even with all of this, i am not itching to get another wheel from the v12.. Usually about a year in i am already looking.. So far even with the current situation i feel i will be on this wheel for quite some time in the future. Quote Link to comment Share on other sites More sharing options...

Mine is from the "1st batch." so the first small order.. All though i feel like that is the same as the "2nd batch" as far as internal components go. I think the changes made between the two batches are minimal. Some people will say the 1st batch may be more reliable.. but i am not sure if that is just people making themselves feel more comfortable. either way i have had no issues so far. Fingers crossed 2 Quote Link to comment Share on other sites More sharing options...

There's lots of info in this thread, but problem is not batch related, the mosfets was under-spec hence the new drive board for all V12 owners regardless of batch. The nature of the problem is such that there is a high risk that the mosfets will die, this means you can still ride around on them until it happens if you want to take that risk, some people rode 2km before it happened and some rode 2000km and it didn't happen yet, generally the more you ride the more probable it is that it will happen, so people riding their V12 saying they have no problem is just them being lucky but taking that as a sign that they don't have the problem in their unit. 3 1 Quote Link to comment Share on other sites More sharing options...

Fingers crossed Thanks for the recap guys, I'll have to read through this thread more. Good to see some V12's are still going at least (at higher risk obv), had assumed they'd all be affected after a low(ish) amount of kms. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post mrelwood Posted May 10, 2022 Popular Post Share Posted May 10, 2022 It appears that the first customer has gotten their new upgraded V12 (og) board. They asked for a confirmation on IM Telegram chat for this Aliexpress bought board, which shipped on the first of May. The photos clearly show mosfets with a marking GP039N15M, which points to a 150V mosfet by Hunteck in the TO-220 package size: http://www.hunteck.com/Datasheets/HGP(B)039N15M_V1.0_090320.pdf 8 1 Quote Link to comment Share on other sites More sharing options...

I wonder if it should read June instead of July, since that would better match with the mentioned 4-6 weeks. Probably better to leave it as July. Better expectation management. Its going to be very hard not to ride it, and crash reports don't really have a pattern. And the weather is finally nice, and I am only just now getting really comfortable riding it. I think I am doomed. 1 Quote Link to comment Share on other sites More sharing options...

I think I am doomed. I think we are all sure to be doomed riding EUC's in general. I always feel like sooner or later something will fail while i am riding.. Weather that be a tire, a battery, or a mosfet, etc. I understand this is not a justification to volunteer for cutout testing, but a cutout/crash is always on the very back of my mind no matter what wheel i am riding. All of these parts and crap are consumable at some rate. None of them will last forever, and many of them can fail unpredictably. For this reason i feel like a cutout or crash is inevitable at some point. 1 Quote Link to comment Share on other sites More sharing options...

From what I understand, while any EUC could fail, its a result of a random malfunction which may or may not happen. Possible but rare. Once in a blue moon type thing. Whereas with v12 its going to happen sooner or later. And then there are one wheels, where you can expect it to happen with some frequency if you aren't careful. 6 Quote Link to comment Share on other sites More sharing options...

Daiko Posted May 21, 2022 Share Posted May 21, 2022 As bunch of local friends are locked in Shanghai for 2 mos already, I think July is more appropriate for out of factory and we will get it around end of August or beginning of September. I've no idea wtf china is doing since no one fxxking die from this covid wave. (Bunch 85+ people die because they are in God's hand but unfortunately they have covid so being classified as covid death, total BS) On 5/10/2022 at 1:14 AM, mrelwood said: Thank you for the announcement!

Bc everything can eventually break down, but with serious quality parts that are backed with robust safeguards in software and hardware, backup parts with alerts on failures and so on you can make the risk so low it's not worth caring about. I think we could get to a state where you are as worried of a cut out as you are that your car breaks stop working going 60mph+ on the highway. Where obviously the risk can vary somewhat over years of hard riding and service or lack there of. Quote Link to comment Share on other sites More sharing options...
