Popular Post fbhb Posted July 31, 2018 Popular Post Share Posted July 31, 2018 (edited) Earlier in this thread comments were made about us all having to wait and see if there would be any visual difference between the pre-production Z10 mainboard and the New performance upgraded mainboards fitted to the production wheels. Well here are a couple of photos I've rotated to give reasonably similar angles of the Two different boards for comparison. The first photo being courtesy of @houseofjob from his Teardown of the E-wheels Z10 and the second photo is of the New mainboard, courtesy of @Chronic. The most obvious change with the New board is that it has been moved over to one side of the enclosure, allowing all the cables to come in from just from one side. I cannot tell if there has been any change to the 14 Mosfets (the numbers are too hard to read but look to possibly be the same, I'm not too sure) The capacitors appear to be the same but there are, however, Two additional small components on the New board labelled C61 and C62. The more well educated Electronics wizards among you may be able to pick up on much more than my un-trained eye!

Popular Post Hunka Hunka Burning Love Posted July 31, 2018 Popular Post Share Posted July 31, 2018 (edited) Looks the same to me? V1.0? I still wonder how they cool the MOSFETs if they are surface mounted like that. I understand there is a large heatsink underneath? Maybe the heat goes through the PCB onto heat conduits to the heatsink? Or maybe the new MOSFETs and firmware don’t need that much cooling? I dunno. Edit: Sharp eye! I think R components are for SMD resistors and C for capacitors. T test point? It’s probably good that they moved the MOSFETs off the mainboard so if it fries one can just replace it without swapping out the whole controller.

Here is another photo with the upper board still in place, as previously configured (using Two separate boards) on the pre-production wheel. Hard to tell from this whether any small changes have been made to this board as well though! I would imagine that it's been a combination of minor tweaks with the additional components and firmware, but that is only really guesswork on my part!

fbhb Posted July 31, 2018 Share Posted July 31, 2018 (edited) Managed to get Two comparison photos now of the old and new upper boards, which do show there have been a considerable number of additions/changes to components! You can also see more clearly how the whole assembly has been moved over to allow all the main cables to exit on one side only.

RoberAce Posted July 31, 2018 Share Posted July 31, 2018 Can someone help me? the wheel is making this strange noise like ruminating that makes when you ride it transmits vibrations to the pedals that even feel under feet causing a small tingling. allthough, the wheel is still at full capacity but feel those vibrations that even intensify during braking. what is happening? Please give me a help, tell me what can I do 1 Quote Link to comment Share on other sites More sharing options...

I'm pleased to see that Ninebot used an ample supply of thermal transfer paste beneath the heat sink. Quote Link to comment Share on other sites More sharing options...

Please give me a help, tell me what can I do No idea. I don't know if it's necessarily bad. My Z10 has almost 800-miles on it and no problems. All wheels sound a bit different after they get broken in. You should hear all the sounds that start coming out of Gotway wheels 1 Quote Link to comment Share on other sites More sharing options...
Marty Backe Posted July 31, 2018 Author Share Posted July 31, 2018 After performing some short speed runs with a full battery, I took the Z10 for an extended run at maximum speed. I was riding the tilt-back near continuously (which is pretty comfortable to do). So at ~80-percent battery you can push the wheel to ~27-mph, but it's really a 25-mph wheel if you don't want to deal with tilt-back. 2 1 Quote Link to comment Share on other sites More sharing options...

Thx Dude Sounds normal to me. Tried doing the same to a new S1 motor and it makes the same noise. Have you tried disconnecting the motor wires to the control board and check if the noise is still there when you turn the wheel? Make note of which wire came from what terminal. You don’t want the wheel to turn backwards when you want it to go forward. Quote Link to comment Share on other sites More sharing options...

That would be perfectly normal. My wheels resonate a lot louder than that. 1 Quote Link to comment Share on other sites More sharing options...

Thank you for your courage to film it all the way! You are the hero! It seems that Z10 getting stronger the faster you go, like motorcycles do? While other brands treat you as a child or do shut outs at high speed, Z10 keeps you racing by adapting pedals angle to the speed? Like a Porsche rear spoiler that wings up the faster you go? Gotway Way: audio warnings, tilt back at speed of your choice, high speed shutout. KingSong Way: audio warnings, heavy tilt back that causing speed reduction. Ninebot Way: audio warnings, gentle tilt back, letting you push back. Invitation to racing fight? Feels very exiting if it so. Correct me if I am wrong! 1 Quote Link to comment Share on other sites More sharing options...

Yes, the tilt-back on the Z10 is pretty mellow compared to KingSong. But I'm sure if I continued to be aggressive push against the tilt-back, the tilt-back would have gotten worse. 1 Quote Link to comment Share on other sites More sharing options...
