@US69 Thanks for the summary. One thing though, after my 2 lock-ups I was asked to upgrade to the "newer" 1.07 about 10 days ago (which I did). I contacted my seller yesterday to ask about upgrading further, as more FW releases have been made. No word back yet. I have not been asked to send it back/replace controller board.

For me, (lock ups at ~40km and 100km), I am now at 255km. It is a very comfortable wheel, so outlook good for me on the FW fix, but will be much more secure if I hit the 500km mark without issue.

 

Sorry, but  i cant speak for ewheels...

Seams he is very busy in the moment. Can you write him -again- and please ask about how to go on? I dont know about his specific arrangements with KS, Sorry again....

Noooo, my KS18L is affected too.

 

Damn I feel your pain. Sounds more and more like hardware issues. 

Perhaps first batch teething issues @US69

Hope it’s resolved asap

@Juick And have you tried to restart it?

You mean when it froze? It was unresponsive to the power button. I pressed it shortly and tried for longer too, but nothing. After I reconnected batteries it can be turned on again, but is almost dischared, it yells at me to charge it up.

Afaik...again...afaik Ian gets his wheels by boat, and not by air plane. Which would mean it was produced 4-6 weeks before 23.7.

So i would !suspect! this wheel to be one of the first produced wheels, first batch, also.....

  1. What I can tell you all is that since I've changed the controller, I never had this issue again... I trolley my wheel for kms and no issue at all... I pay a lot of attention to the sensor calibration. I use the sensor all the time, and since it is calibrated and with new firmware it works perfectly most of the time... To be honest, I was the first person here saying that it's a firmware crash because of the sensors being activated to many times but now I'm not sure anymore... I don't believe that it's the oscillator too... I'm still thinking that it's something about firmware crashing in a very very specific situation... That must be damn hard to reproduce for KS.

Yeah, while locking the wheel doesn’t respond at all, not by buttons, not by app!

After “reset” it should work again...but as said, please contact Ian, and if he isnt aware of the problem, ask him to contact KS, or even me if because of the “time barrier” he doesnt reach someone fast enough!

I meant after you disconnected the batteries (at least you knew what to do, I was just watching my wheel dying in my arms :( ).

I dont want to start to speculate...but seeing this fault only on very early wheels...call it “first batch” if you want...i am personnaly more and more convinced its a hardware fault! 

Reasons: Its a -new- 84 Volt board...if it would be still in the firmware, and it would not be the sensor, all other KS would have this fault also! But they dont, never heard of a fault like that!

So iam very convinced its a hardware fault...especially as those who got their board change, never ever had problems again....

But again: That is my -personal- speculation!!!

 

I will inform you all as soon as any new facts come over from china!!

Yes I know there is nothing sure about that, it's only speculations... So are my... The lock happens to me just about a 10 days after getting the wheel and the the board I got was not 100% new. It was already used (for a very short time) so probably the same as the orginal one on my wheel... I even compared both boards and there is no visible difference... Anyway, good look to KS with investigation...

You wrote that you managed to disconnect the batteries after about 20m. Since then have you tried to restart it?

 

Yeah, when I turned it on, it tilted back and yelled very loudly "Low battery, please charge". In those 20min it drained battery from 2-3 led lights to zero. I'm charging now, first 10 minutes app displayed 0%, now it is going up.

Thank you for your support, I did what you advised and I'm waiting for response from Ian.
