The other i was on my usual route. About half way the wheel started to jerk like crazy. I turned it off and on again but still after a couple feet wheeling it it jerks again. I opened up the wheel, checking the mother board, connections and axle. It seems that everything is tight and good. I accidentally reset the wheel my unplgging the battery connectors and pushing the button again to discharge. I put back all the screws and casing of the wheel and tried it last night and it was fine now. Do you guys think it was a software issue? I’m on the latest firmware. I didn’t see any debris stuck on the wheel while opening. Hopefully it stays good that way.

My s plus I just received moves forward by itself unless I change the balance calibration to almost the lowest it can go which I’m not sure if that’s normal as my friends s plus balances at it’s normal setting of -.8. Also I attempted to recalibrate and the wheels spun in the same direction as opposed to opposite directions so I’m not sure if that’s normal either. Please let me know if anyone has any insight on how to further resolve this as I can’t find anything online. Thanks so much everyone!

The currently on fire 16x thread is hard to dig through to find actual issues with the newly released KingSong 16x between all the comradery between us. I am creating this in hopes that we can have a thread listing and tracking the issues that are currently being reported with the first batch of 16x. I am waiting on the second batch and curious about what they will fix before or during production is the largest driver of this thread. NOTE: I will try to keep this post updated with any issues folks list below. ChangeLog at bottom Latest Firmware = 1.06 (click here for post with release notes) —— Issue: high speed/stress oscillation problem and will be out in a few days.Recommended everyone update to this firmware as soon as possible as a safety precaution. Source Fix: Firmware 1.03 fixes Issue: There is another problem where the pedals will not stay level and regularly show a very slow oscillation in some cases which makes the wheel unridable. This might be a hardware problem. Kingsong may or may not have stopped 16X production temporarily to fix this (board modification I guess). Not entirely clear what is going on, here's the source: click I would expect any good dealer to be informed about this and only ship out wheels with the fix from now on. That is conjecture. Fix: Issue: The 16X has a notable "gyro effect" where it becomes hard to turn the wheel above a certain speed, it will try to keep going straight. Like the Z10. This is due to the standard tire that comes with it (the one with a colored stripe on one side). Replacing the tire with a different one, like the CST tire the Nikola has or the Chao Yang tire the 16X prototype had, removes the gyro effect almost entirely. This is only due to the standard tire that comes with the 16X, nothing is wrong with the 16X itself. Fix: Not sure if this is really an issue vs personal preference, 16x tire thread going on HERE. Issue: Battery level not showing up correctly in KS app android ver. 3.1.3 & iOS version 1.3 (or Darknessbot not sure about WheelLog) Fix: n/a Issue: Bluetooth module might cause interference as reported by others, I don't have the wheel yet so I have not tested it. by @Unventor Fix: Process below in this post. Shared with permission from Jason @ ewheels | @Jon Stern states this is still an issue and Jason @ ewheels has looped in KS rep via email. Issue: Handlebar screws rattle loose while riding. Fix: Process below in this post. Shared with permission from Jason @ ewheels Issue: Firmware 1.06 introduces throttling at 76V (50%ish) with new firmware. Fix: not upgrading to 1.06 Issue: Firmware 1.06 for some has introduced noises that are bothering dogs around where it was not on 1.05. Fix: not upgrading to 1.07 ------------- Process for Updating the Bluetooth Music Module Applies ONLY to the KS16X Download the pdata.bfu“ file (link at end) AND a MP3 music file to a FAT32 Formatted USB stick—place on the the parent folder, without folders King Song 16X Firmware File Switch on the KS16X Go into the App & verify the Music function is enabled from the settings. Insert the USB stick into the left USB socket The Music module makes the announcement: "Enter Music Mode", then the installation process starts After installing the firmware, six long beeps will sound Disconnect the USB stick & switch off the Wheel Delete the .bfu file from the USB stick Applying Threadlocker to the handlebar screws: Some feedback received from some of the first Customers, was that during use, vibration from riding can cause handlebar screw to fall-out. In the package with the charger, you should have received a small bullet tube of threadlocker, this is to apply to the screw that secures the handle to the retractable telescopic rails. Please allow it 20 minutes to dry before using. Change Log Updated 2019-09-07 @ 0930am PDT - Added issue with noise bothering dogs after 1.06 firmware update.

My KS18L died today, here is how and what happened: - Firmware version 1.0.7, Battery 90%, Mode Beginner, Speed Max 25Km/H - Battery was 100% and I drive for about 8km, temperature outside was around 33°C. - After driving, I took the wheel in trolley mode, as I was shopping, and walk with it for about 15 minutes inside a shop with aircon. - After 15 minutes walk, the wheel suddenly tremble once and then switch off. At last that was what I was thinking because there was no lights, on/off button has no effect etc... - I noticed that the wheel was becoming more and more warm, despite give no sign of life... Also the wheel was very hard to turn... I think it's a motherboard issue... Probably Mosfets died and made a short circuit... I decided to open the wheel and disconnect the battery cable as it was becoming more and more warm and I was worrying that it can take fire... I've noticed that motor cable was very hot too, so it just confirms to me that there mosfets died in a "short circuit" mode... Also the fan was running and there was a green light switched on on the motherboard... No other signs of life... No bluetooth... etc... Hope this kind of details can help King Song to make a fix for it. If there are any questions, please feel free to ask.
