After patching my first KingSong wheel (this wheel), it's really a piece of cake. You will hear some people say that it's easier to remove the wheel than a Gotway, but I contend that they both take about the same amount of work, just different work. A lot more screws with the KingSong. I think I prefer Gotway, but the difference isn't night-and-day.

Well, that is a bit disconcerting, because it indicates something has changed. Of course it's a judgement call as to whether it's important. If it were my Z10, I would continue riding but if I ever noticed any strange handling behavior, then I would stop.

Nice collection of wheels that you have there (in your signature)

Great report @gotmotion2016. And the inside looks nice and clean I have always said that the ACM is my favorite general purpose wheel. It's a little tank , and I was disappointed when Gotway stopped making it. I have two ACM2's, and although I will probably never accumulate the distance you have (because I split my riding between lots of wheels), I'm hoping that I can still be riding them years from now.

Loose axle nuts give the symptom of extra 'play' in the pedals. Vibration is usually from the control board. Guess you'll find out when you open the wheel.

Try playing some music through the speaker and see if this sound changes. Also, does the sound change as you move the wheel back and forth? I hear essentially nothing from my wheel. The Z10 is one of the quietest wheels available.

I get even more stares when I'm riding with this gear on, that's for sure. A couple of months ago I heard one little kid ask his mother if I was a robot

Yeah, it's particularly special right now, with the snow capped mountains and clear air. There's a fairly narrow window where I can take this kind of picture in Southern California.

OK, I've never heard anything like that from my wheel. Is there any chance that it was coming from the speaker and not the motor?

Still plenty of snow in the mountains above Southern California, even though it was about 80-degrees where I was.

My Z10 has had the pedals go wonky (technical term) 3 or 4 times. While at a stop, such as waiting for a light, the pedals have tilted back to a degree that I had to get off the wheel. This hasn't happened now in a long time. But I still have issues where when I turn it on the pedals are leaning back and I have to do a calibration. So in general, I think Ninebot did a crappy job of designing the hardware/software that maintains the pedal calibration. This is the only issue I've had. Fortunately the symptoms do not appear to be getting worse.

If it's a vibration there's a possibility that the control boards is slightly loose in the shell. Check each screw that holds the control board down and make sure they are tight.

This Wheel is a Kick-butt Distance Wheel Beautiful mid-80's day in Southern California so I took the KS18XL for a distance ride. 51-miles with 31% battery remaining at the end. This wheel is amazingly efficient compared to any other wheel I've ridden. And I did a lot ~20-mph riding on this ride, with lots of wind too. I continue to be very impressed with the KS18XL. I also used this ride to test my flat repair. I had to remove the tube from the tire to discover two punctures. I patched both and re-installed the wheel. It occurs to me; why do many people go the route of replacing a $20+ inner tube when they can be easily patched? Hmmmm.

@Duf has been selling those for the last year. He stocks them at his website. You can see the EUC Army logo on the side.
