Z10 balancing sensor is getting wonky?


Recommended Posts

Hey all, I'm trying to determine if this is an issue with the latest firmware update, a problem with the control board, or another issue entirely.

Most recently I have noticed that my Z10's center of balance is making more drastic changes at low speeds. When I start the unit up and begin making small movements, I can feel the sensor reset slightly and at times have had the footplate tilt back and forward a significant amount before slowly resetting. This isn't as extreme as the issue linked in the post below, but is significantly different than when I got the unit. Again it hasn't affected me too much at higher speeds. Is it possible for the control board to slowly wear out?

Wheels  need re-calibrating from time to time, or weird stuff like this happens.  There's a recent post about how to do it on an InMotion wheel (not the one above).  I'll look for it.

EDIT.  Sorry, I can't find it.  It was current just a few days ago, but none of the recent titles ring any bells.

Basically start the wheel.  press the wheel disengage button and tip the wheel over on its nose so it balances there (on a perfectly level surface, don't assume check it with a level before you begin)  Open the app find the section about pedal angles the second option is for-calibration.  Follow the instructions.

Sorry, that's all I remember.  I've never even seen an InMotion wheel in the plastic.

The Z10 does have a slight wonky balancing algorithm on the current and past firmwares.

First, I would re-level your Z via manual, non-app calibration, per the below video. (as I've found the app-based calibration not reliable)

Then, me and a fellow local rider have a hunch that delving in softer pedal response settings can throw the pedal levelness off whack, so I would stick to the hardest setting, think it's 0 offhand(?)

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.

@houseofjob tried your calibration today and the wheel seems to be performing pretty well from my quick test. Thanks for that.
Will report if I experience anything strange later.

Thanks for the thoughts all. I was mainly concerned if it was a hardware issue and if I would need a new board. Does anyone know if it's just an accelerometer that's in the board that keeps these things upright, or what?

@dantaylr glad it worked so far!

Pretty convinced it's just the recent firmware. The preprod was not this bad, albeit we had it for a short span (plus I didn't experience this drifting balance on my Z this bad on earlier production Z firmwares)

I have not had to re-calibrate my Z since I purchased it so I am not the best person to advise, but I don't see how different tyre pressures would affect the front/back calibration?

That's right -> it is 0 😎

After reaching 3000km on my Z10 it started to require recalibration. Sometimes even after each ride. What could be wrong? 

Unfortunately, this is a control board issue that some, not All Z10 owners experience. For some it is a lot more random than in your case, so only happens occasionally. The only fix if it is of major concern, would be a New control board. My personal experience is that I have Not had any of the known issues at All with my Z10, which is now approaching 8000km!

I replaced the MOS board (the larger - buttom one) few days ago and unfortunatelly it didn't help much. Should it be the other board - the smaller one?

On my wheel I have the same observation. Turning it or tilting it sideways in a standing position makes the wheel a bit wonky. But it did not affect my ride lest in very slow curves.

Bonjour à tous,

Voilà je viens d'acquérir d'occasion une neufbot Z10 avec 120 km au compteur.

Seulement voilà tu n'as pas de soucis !

Après quelque tours de roue elle bip bip bip et bascule l'angle vers l'arrière.

J'ai effectué un calibrage avec l'application ca ne change rien.

J'ai aussi essayé de faire comme dans une vidéo youtube une réinitialisation du calibrage.

J'ai toujours le problème.

Que dois-je faire ?

Hello everyone,

Here I just bought a used neufbot Z10 with 120 km on the odometer.

Only here you have no worries!

After a few turns of the wheel it beep beep beep and tilt the angle backwards.

I performed a calibration with the application it does not change anything.

I also tried to do a calibration reset like in a youtube video.

I still have the problem.

What should I do ?

Hey,

in which colours do the RGB Lads flash? Is it only red or blue and red?

You can download the ninebattery app and look if there is any big voltage difference. If so, there is a defective cell. You would have to replace it --> pretty complicated.

Does the app show the right battery percentage (both bars for the battery) or just one big?

If there are two bars for the battery percentage, do they show the same state?
