Yes, you'll see it in my Z10 teardown video I still have to edit.

Even though I work in music & have an audio engineering (record/mix) background, I'm not well-versed in speaker construction. Maybe you can tell below? (sorry, image is a little overexposed)

Great demonstration videos!  Looking forward to the teardown video.  The way you NYC people ride (fast) makes the Z10 look like a good quality performance wheel.  But not at the level of Gotway or Kingsong.

That video with @Tishawn Fahie was insane, not only that he was riding so fast, but that you and @Citi Wheel were able to keep up and film at the same time.

It reminded me of that movie Premium Rush, with the bicycle couriers that knew the landscape so well that they could anticipate every situation.

That mk3 audio board above the piezioelectric speaker is interesting, looks high quality, but I know nothing about this technology.  I just like the neat wire twisting and routing.

See Z10 heatsink speaker / buzzer holes, and the flip side in relation:

 

Unfortunately, I'm not like @Tishawn Fahie and have much more fear! As soon as the tiltback initiated, I was slowing down!

Also, FWIW, towards the end, was riding on the latest 0.4.4 Firmware, which really neutered all system sounds across the board, as reported by @Turbocharged (power on sound, lift motor disengage sound, etc.)

 

LOL ??

It's you're call, but @Jason McNeil can attest to this: I am a very anal-retentive person in terms of organization, have toredown my fair share of wheels, and made sure to test ride the demo Z10 a bit, post-teardown and putting back together, to make sure everything was in order. (plus, we'd all be sad not getting a proper MB SoCal Mountain stress test! ?)

 

Wow, looks professionally designed and put together, not like the inside of a gotway which looks like some kids put it together.  Lol

@eddiemoy and I get along just fine BTW, we just take shots at each other for fun

Do you have to take that cover off to put air in the tire?

i guess they had their reasons but i think i would have preferred higher, bigger pedals.

are these magnetic like the e+?

Looking forward to the tear down video. I’m impressed at the superb engineering that went into the Z10 ...right down to the shell’s molded bridges that form a built in harness that perfectly routes the wires. You’ve got to love all of these little Intricate  engineering techniques that went into this machine!

This kind of looks like a Gotway wheel, circa 2025

No, if you see rubber nub triangularly between the Ninebot logo, trolley/stand, and pedal, you open that to access the valve with a valve extender (a flexible one was included with the beta, but I found my usual straight valve extension much more suitable).

I actually don't mind the 5" pedal height, but yes, bigger (specifically longer) pedals would be nice.

Yup!

Nice!  Anyone notice the two sets of rubber gasket sealing the electronics compartment?  Also there are no large capacitors.  Are those surface mount 100v electrolytic capacitors?  Plus those dual battery connectors attached directly to the control board look awesome and solid.  They look screwed onto physical locking mounts.  I wonder what the motor wiring connectors are like.  Can't really see where they terminate.  

Where are the MOSFETs?  I wonder if they are hidden from view and sandwiched between the board and a wheel facing heatsink.  Oooh I see it is a dual layer board configuration.  You can see the smaller board on top and the caps are on the lower layer where the MOSFETs and motor wiring connectors must be located.

You can also see the extra hall sensor cables following the other set.  Looks like someone put some serious money into engineering a well laid out control board here.

ya, the guts look nice, like somebody was trying.

these bank alarm guys i use to work with at diebold back in the seventies did very beautiful wiring. much easier to troubleshoot. the electronics wiring on my boat makes me vomit.

The rubbers gaskets are another awesome engineering attribute of the Z models. Being today is the one year anniversary of my truck rolling into the lake with my wife’s new KS14C   (she never did miss it) I wonder if the engineered  Z10 seals would hold up to this level of water infiltration?

Right at the bottom of the photo you can see the access port for inflating the tire.  You can barely see the valve stem.  Thanks to @houseofjob for answering a good question from @novazeus

Let's not test it, m'kay?    Happy Gladyouarestillalive Anniversary!

Have anybody measured wheel dimensions? Would it be possible to use a motorbikes or so on? ..

It's reassuring to see those thicker motor wires which were a major concern from the February prototype—I must have sent my  Beijing contact ten messages with those photos with the GW ACM melted wires that @meepmeepmayer posted way back, driving home the message of the need for thicker gauge, who knows, maybe it had an effect   

@houseofjob forwarded over some other pictures of the Wheel denuded of the motor & battery, says it's going to be a nightmare challenge to gain access to that motor for changing the tire. It's interesting to see from that picture the 1kWh battery is installed on the almost entirely on the right side, where you then might expect the uneven weight distribution to affect the center of gravity/balance. That's very likely why there's that massively great 1kg heat-sink on the opposite side, to even it out with a bit of ballast.

idk what the composition of that tire is, but if it’s anything like a motorcycle tire, it will be years(me decades)for most people to ever have to change the tire. plus it being tubeless and on a wheel, plugs would be perfectly fine for a fix.

Yup, exactly as you said I believe. 

This view without the top board might help~ The Top board plugs in via those 12 & 20 -pin connectors

Sorry, I forgot to snap a pic with the motor wire connectors actually connected, but you can see on my teardown vid when I post. 

They screw in like the power cables in to the empty silver hole-fixtures on the board.

Is screwing the power wires better than soldering? I want to know what you guys have seen that makes this better

I guess screwing in is akin to crimping(?) Not sure.

I know my old KS-18A used a similar screw-in method for the motor wires, until they moved to MT60 connectors I believe (don't quote me on that).

So the Z10 uses 14-MOSFETs   Let's hear from all the people that keep saying Gotway should use better engineering and get away from using 12-MOSFETs. Or maybe all of the MOSFETs aren't for the drive electronics?
