I almost hit a lady on the crossing because I could not brake in time. I managed to jump off it and some how catch it. I don’t know how I did it but it was so close. Second, I had to stop on a red signal, again could not stop in time. I had to again jump off it. The slow brake is a real danger. Be careful. I won’t ride mine on roads again. I came home shaking. Paul…. I really think you are asking for trouble riding on roads, in town before you have a good few hundred miles on the wheel, and you really feel that you are Honestly comfortable on it. Ride like everyone, and everything, every other vehicle you see…and those you don’t see, is trying to kill you. A really good skill to learn before you go …Full Public…is to learn to ride at pedestrian walking pace, it’s not easy, but teaches you so much. Never be over confident when riding…it applies to all of us….You’ll just end up looking a twat at best…and seriously hurting yourself at worst. So, take care buddy, and enjoy your riding…….And stop frightening old ladies! 😂 4 Quote Link to comment Share on other sites More sharing options...
Paul g Posted February 19, 2022 Share Posted February 19, 2022 I have no issue riding at walking speed on the sidewalk among other people. This was not the issue I had if you read more carefully. Quote Link to comment Share on other sites More sharing options...
Paul g Posted February 19, 2022 Share Posted February 19, 2022 (edited) Today my MOSFETs burned. I took the wheel out, I put it in split mode acceleration 100%, braking 30%. I liked the way it brake. Changing it to 30% made it much easy to brake faster. While I was doing some braking, it cut out on me. This was the first time I had a cut out. The second cut out it burned the MOSFETs. The wheel is dead. The screen was still on, but the wheel could not stay straight. Edited February 19, 2022 by Paul g 3 Quote Link to comment Share on other sites More sharing options...

Your V12 is a marvelous machine except for the motor controller. Each of hundreds of early V12 motor controllers has a short service life, exactly your experience. Find a YouTube video of a V12 going through the woods at 40 miles-an-hour - imagine what happens when a MOSFET fails at 40 miles-an-hour. The manufacturer didn't review the V12 before going to production and one bad component slipped into an excellent design. Until EUC manufacturers include pre-production reviews EUC buyers are post-production testers of everything that can fail. EUC manufacturers will improve; MOSFET failures, battery fires, foot-rests falling off will be rare. BUT . . . Until EUC manufacturers improve EUC users are post-production testers looking for problems - the hard way. Research private aircraft built pre-WW2. EUC manufacturing is destined to improve in a similar way except the crashes are less serious. Quote Link to comment Share on other sites More sharing options...

The conclusion I draw is they learn slow and make a lot of big good decisions, but also a lot of big wrong decisions. 1 Quote Link to comment Share on other sites More sharing options...
Steve Evans Posted February 20, 2022 Share Posted February 20, 2022 folks, do we have any idea of the percentage of batch 2 v12's that have burned their mosfets at this point? Quote Link to comment Share on other sites More sharing options...

Cress Posted February 20, 2022 Share Posted February 20, 2022 I look forward to 1) side-by-side comparison of old vs new boards and 2) visual comparison of mounting at heat sink for old vs new boards and 3) Identification of the MOSFET on new board and 4) any related information forwarded from Inmotion and/or any major Distributor. I'll send email today to Jason at eWheels.com asking if he has anything to add. 3 Quote Link to comment Share on other sites More sharing options...

Silverfish Posted February 20, 2022 Share Posted February 20, 2022 That facebook post says all owners, but the message they are quoting seems a lot more like its just the owners who have already had their cut outs. 2 hours ago, terlikaa said: New info from Alien Rides https://www.facebook.com/groups/inmotionv12/permalink/523488712416721/ Quote Link to comment Share on other sites More sharing options...
Richardo Posted February 21, 2022 Share Posted February 21, 2022 Odd that the boards have almost shipped but we have no info about what has been revised/changed. was it shared and i missed it? Or is inmo keeping it secret for some reason 2 Quote Link to comment Share on other sites More sharing options...
Popular Post terlikaa Posted February 22, 2022 Popular Post Share Posted February 22, 2022 It would be great if someone from IM could confirm if all V12 users will receive the new board. @Cecily Inmotion 7 Quote Link to comment Share on other sites More sharing options...
conecones Posted February 22, 2022 Share Posted February 22, 2022 Adding another item to the list of weird behaviours that my V12 has: - Screen turned off mid-ride. When I came to a stop, wheel immediately shuts off (no sound indicator). I swear I read about this happening to someone else before but can't find the post. Anyway here are the other glitches: - "Please Repair" alarms when accelerating/braking hard. Does not come on regularly. Sometimes occurs when not braking/accelerating hard at all. Hard to replicate consistently. - "Overload, please get off" alarms. Same condition as above. - Headlight randomly stopped working after motherboard swap. Had to open unit and re-plug connectors. - Headlight flickers in Auto mode when wheel is not 100% stationary (like when on a bus/train). Auto high beam is set to 10km/h+ so that shouldn't be the cause. - Split mode settings resetting (resolved by itself when using touchscreen only while wheel is on). Anyone else experience the first few? At this point I've decided that if I faceplant again as a result of board failure, I will return the wheel and never come back to Inmotion as a customer. Months later without an official recall notice or a "do not use device if SN begins with #" announcement, I am not letting this $3000 investment sit unused in the garage for months while waiting for another "improved board" which would likely still require months of actual customer testing before we can definitely say its fixed. I cannot in good faith sell this to anyone, so I will just ride it and leave it up to the cut out gods . 2 Quote Link to comment Share on other sites More sharing options...
supercurio Posted February 22, 2022 Share Posted February 22, 2022 (edited) @conecones absolutely understandable - everything. I believe that the replacements board will arrive sooner than later tho. Since it'll be on everybody's and their distributor's radar, failures with the new board will be identified without delay, and reduce the amount of time before as a community we could trust the fixed V12 or not. On the basis that you also have Nikola+ and RS19 HT listed on your profile, I'd like to make a new attempt at gently nudge you to ride these in the meantime 😊 Also because the mechanism you describe matches the sunk cost fallacy.

What do you think? replacement boards are coming for people who have already had catastrophic failure. There isn't one coming for the wheels that haven't died, and since I don't want to break myself I'm not going to ride mine until it does. The last official word I got was the Inmotion was confident in the spin test, and that was fairly recently. I'm not getting sold on internet rumors. Their public position is the position I am listening to. And the current message is "that's a YOU problem, we already have your money".

Cress Posted February 22, 2022 Share Posted February 22, 2022 For consideration and comment and not an authoritative recommendation for @conecones electrical issue: Duck-Oil (Europe) and ACF-50 (when you can't find Duck-Oil) is used as anti-corrosive on electrical connections and exposed metal in everything that flies, drives or floats, despite anti-corrosive products not being universally approved by electronics manufacturers (the open issue is circuit boards and associated components). I'm looking for suggestions and comments related to Duck-Oil-kinds of anti-corrosive for EUC maintenance particularly EUC electrical plugs after the plug is mechanically clean. Cost is more than $2.00 / ounce but the smell is wonderful. Quote Link to comment Share on other sites More sharing options...

When i spoke to ewheels recently, it was mentioned all v12 boards would be replaced. I had a different smaller issue I was troubleshooting with them, mentioned i would like to purchase a new board if and when they become available and they said that the board would be replaced even without a failure. No timeframe, but basically only because of supply chain issues. This was last week. Edit: I dont know if this is only ewheels, or certain distributors willing to kick in.. or if this is an inmotion thing.. I also expect that this situation is probably still fluid and can possibly change.. I also want to state my v12 is fully functional, and both ehweels and inmotion reps have responded to all of my questions regarding pretty much everything with the wheel so far.
