He did:

Not my video. Very nice follow-up thoughts on the Westwheel 2 event in Las Vegas by @TMoats (he didn't post this video here, so I do).

Not my video. New learner.

@Flyboy10 Oh wow. Are you 100% sure it didn't get through the skin and you might need some shot? What about your pants? Ruined?

Not my video. Not sure if this has been posted yet (it's a month old and has few views, so maybe not). Nice long exploration ride, looks like a really fun long and interesting route.

No, just randomly watched a video and there you were.

Not my video. Second EUC video from this guy. Nice afternoon/evening group ride through NYC, with some nice lighting. @houseofjob is part of the group if I'm not mistaken, also they hav a cat girl.

Such a cool tour and road! The vegetation and rock scenery up there is (for lack of a better word) adorable. And the radio station at the top looks very Half-Life...

@Rama Douglas You made the best videos of the Vegas Meetup so far! And you even made your own music for them!

Wow the view from that road Dream riding location!

If you google "21700 vs 18650 density" it seems the 21700 have 20% more energy density. I hope they won't make wheels too expensive though.

Info about the 126V Nikola timeline. Originally posted here but I moved the rest of the stuff (a lot of new info not about the 126V Nikola) into its own thread.

@Afeez Kay I put this into its own thread. Too good to be hidden in the 126V Nikola thread. Feel free to edit the first post (title) as you wish, and keep the info coming Poland, China (multiple manufacturers!)... how did you come up with this idea? Isn't this travelling quite expensive? Anyways, awesome!

It's annoying that these Chinese Ali sellers (green and fashion especially from a few accounts here) are so stingy. New board and $300, really? Did he look at the photos? On the one hand, they can offer well-produced modded wheels. On the other hand, this strange behavior. I think it must be a cultural thing where he nominally does something (completely pointless) and then everyone pretends that is ok and he saved face, or something strange like this (or just trying to be cheap). Certainly not looking at it from the perspective of the buyer. Good you didn't give in to any of this BS!

@Afeez Kay Wow, and great work. How about starting a thread about your glorious EUC world tour and the new wheel rumors? This stuff shouldn't get lost in some random place!

Looking forwward to see more of this. Gloves (finger protection) + wrist guards in one is a thing many people will want!

@GyroRideRz I put this into its own thread instead of an unrelated Z10 thread. Also everyone please post in English.

@sc3000 You can edit your posts now.

@Blueblade By top speed I meant the no-load, freewheeling speed (just the zero torque speed). So only looking at the properties of the motor itself. Of course wind resistance will ruin everything in reality, but I still haven't given up on EUCs on the moon That's how that post was meant.

I guess you solved the conundrum A self-balancing vehicle can never work at its limits, or you'd faceplant. So (unless you overlean) it's never the battery, but the motor behavior that counts. And that just gets better with higher voltage.

There's a huge difference in drag between 45-50kph and 55kph. Gotways are faster so the drag quickly reduces the Wh/mile efficiency. In theory that's all right. But then why does the 100V Nikola have better acceleration and top speed, as found in @Marty Backe's blind test? So the firmware or something else has to play a role there for practical behavior. I'd be very interested to separate the cold hard motor facts as you described and whatever else leading to the practical results we have.

No, it mostly would not mitigate that. The problem at high speeds is wind resistance (drag). Drag is the main power draw in EUC riding, and it goes up like crazy with speed (double the speed, 4x the drag). Same reason why you get insane range when you go really slowly or with lighter riders (which are smaller and have much less wind resistance). So while high voltage wheels might (or might not) be a bit more efficient at high speeds, that still doesn't solve the main problem that high speeds simply means high drag losses. The Gotways are faster than others and that's where you really feel the drag killing your battery. That problem won't go away, no matter the internal electronics, high voltage, low voltage, whatever. You simply have a higher power draw when riding due to the drag, so your battery empties quicker. Try seated riding for reducing your wind resistance losses

84V: 1600Wh (two 800Wh battery packs), 800Wh, 1300Wh (2x 650Wh), 650Wh, 2100Wh (2x 800Wh + 500Wh extra battery) - all available now 100V: 1845Wh (three 615Wh battery packs), 1230Wh (2x 615Wh) - all available now 126V: unknown, probably 1600Wh, possibly others - some time in the future, Gotway is "testing" the 126V Many dealers skip the less popular/mass market sizes and only sell the 1600Wh 84V and 1845Wh 100V.

Nice math! Higher voltage means less parallel blocks which negates exactly the lower current requirement. So the cells are stressed exactly the same (for a given power requirement and battery size) regardless of the battery configuration.
