You better squeeze them legs really hard on touch down or you and/or the wheel will take off.

I for one would like that. -That way you would know that wheel is somewhat robust. It won't fail you after 1-2 weeks.. Every wheel should be tested like that in my mind.

Mishkin Posted September 27, 2022 Share Posted September 27, 2022 I'm not a Facebook or YouTube expert but I think they have pulled the video from being public and the Facebook post has also gone? Being revised? Quote Link to comment Share on other sites More sharing options...
Popular Post supercurio Posted September 27, 2022 Author Popular Post Share Posted September 27, 2022 (edited) @Mishkin the YouTube video is still here, but the Facebook post is gone. There is no doubt that they were taking a beating in comments as customers spoke loudly about their expectation: getting replacement for potentially faulty safety-critical parts. The landing test being difficult to execute certainly doesn't help. I hope they won't give up on the whole thing and still hope for a resolution. The reality check can be brutal, but there's no way around it. Edited September 27, 2022 by supercurio 3 2 Quote Link to comment Share on other sites More sharing options...
Elliott Reitz Posted September 28, 2022 Share Posted September 28, 2022 (edited) Well as I reported here this morning, my wheel bricked itself today. Showed Er 17 (hall effect sensor). So I opened the motor expecting the worst. The good news was that the wiring is fine and the stator has not slipped. One of the bearings is not smooth and should be replaced when I re-assemble (after adding the pins). The seal for that same bearing wasn't fitted properly either - maybe that had something to do with its intermittent knocking/pop sound. The bad news is I think I need a new controller (again).

mrjuggles Posted September 28, 2022 Share Posted September 28, 2022 I would have rather they properly tested the motors to begin with. I for one, would like that even more. Quote Link to comment Share on other sites More sharing options...

I for one would like that. -That way you would know that wheel is somewhat robust. It won't fail you after 1-2 weeks.. Every wheel should be tested like that in my mind. Of course I would want to have a tested wheel, but not destructively tested. In this case motors from known time period are very likely failing. The suggested test is hard to accomplish. If it is such a good test, why it needs to be done 15 times? How can I be sure doing it right? Can it fail at the 16th time? The only way to know is to repeat tests until something breaks. It can be the motor or something else. It would have been better to make a recall for wheels manufactured before KS started fixing motors. They could have also offered an option for the owner to install motor pins with provided parts and instructions. The suggested test should be done after the motor is fixed. 4 Quote Link to comment Share on other sites More sharing options...
UniVehje Posted September 28, 2022 Share Posted September 28, 2022 Looks like there's a real risk of KS going bust because of this. They cannot afford to recall and replace thousands of motors. And if the failure rate becomes too big and we start seeing too many face plants because of a known fault, their reputation will take a devastating hit. It will be interesting to see how this affects dealers. Is this kind of known risk a warranty case or not? Do we have to wait for the motor to break before we get a new one under warranty? If you release a car that has a known <1 % failure rate in brakes there's no question all units will be recalled and fixed. The potential for a serious injury is too high. We have now a failure rate for the motor in the 15 % range so far. And we know that stress test doesn't always reveal the fault. And the test suggested by KS is extremely difficult for an average consumer to perform. 2 Quote Link to comment Share on other sites More sharing options...

I've now had my wheel out of my use for five weeks already because of a battery failure. I would hate to send the motor also to service for many weeks. I'd accept this option during the winter when I cannot ride. 1 Quote Link to comment Share on other sites More sharing options...

And the test suggested by KS is extremely difficult for an average consumer to perform. They had plenty of time to prepare motor replacements all this time when they were stalling. Since July (or before) they already knew about the problem and fixed it in factory, at this point they could start shipping out as many replacement motors as they could produce to resellers before announcing anything so that people can easily get a new motor from their reseller at time of announcement (which is now 2 months later). They know about the drill+pin fix, why not have a dialogue with resellers first and see which resellers would be able and willing to perform this type of retrofitting (for compensation of course), that might have saved a bunch of motors from failure. As it is now the whole thing is handled very re-actively instead of pro-actively and it also brought them backlash from the community for understandable reasons. 1 4 Quote Link to comment Share on other sites More sharing options...

As far as I can see, most engines on the market are made in approx. the same way, with the same pieces and even serial number marking, and even if it is China, there are probably rules there that make it possible for Kingsong to pass on the responsibility to those who produced the crap, someone will have to pay for the party...

I don't think any of the EUC companies manufacture the motors themselves, S22 motors are manufactured by a company called ZX I believe, same motor manufacturer also supplied motors for the Begode T4 (which seems to have the same problem). Regarding supplier or subcontractor, responsibilities or fines or whatnot from what I understand it doesn't really work like that in China, there is no liability, this is what I heard could be wrong.

meepmeepmayer Posted September 28, 2022 Share Posted September 28, 2022 220306 is very likely going to be March 6th. Nobody uses year-day-month, not even the usual suspects that use month-day-year. Chinese use year-month-day anyways. So in my opinion it's a very early motor. Whether that is good (before the slippage issue) or bad (affected by the slippage issue) I don't know. 1 1 Quote Link to comment Share on other sites More sharing options...

I bought it last February via AlienRides auction. Guessing it decodes to 2021, December 21st. My S20 passed all stress tests and is now open because it bricked and reported a hall sense error (17). There is no visible slippage - so I think it got lucky (while needing another controller). I will install the pins while its open assuming I can get a working controller.

Popular Post 5Cauac Posted September 29, 2022 Popular Post Share Posted September 29, 2022 Look at what came in the mail today!! A shiny new "S22" stamped motor manufactured on the 2nd day of July, 2022. In comparison, here is a photo of the original motor stamped "S20" manufactured on "Cinco de Mayo" 2022. (Wait, What!?) I still need to confirm I did in fact experience a stator slip by opening up the motor so stay tuned for that. Does anyone know if they started stamping S22 starting in July or are there any motors stamped prior to July with S22 but known to have the stator issue? 5 3 Quote Link to comment Share on other sites More sharing options...

Want to sell it? I want a few of them since they fail so often. Anyone got a $ource for motherboards (besides my "warrentee" via dealer, they can't get parts very well either).

From what I've heard, the "fix" didn't go in until sometime in July, and yes, motors that have slipped were made before July 1 1 Quote Link to comment Share on other sites More sharing options...
