Offtopic stuff split off to

I can only offer my condolences. The first "S**t something's wrong, I don't want to repair this, nyah" experience is never a happy one, neither is having a non-working, semi-disassembled wheel lying around. And you have this really early. At least you'll be confident in your disassembly skills from now on, and future tire changes and disassembly are no longer daunting, just routine work

Those pedals look neat! Don't the Inmotion pedals also fit on Gotway wheels? New option for Gotway pedals?

You should be able to send PMs now

An MSX would certainly be a great first (and forever) wheel. Great wheel, and should be quite easy to learn on it. Range highly depends on your speed. 1300Wh should give you about 50-55km at between 30kph and 35kph. I'm wondering if the price is a bit too high, but I might be wrong. There were some used 84V MSX 1600Wh going for around $1100 and up (if I remember correctly), but maybe with shipping and Canada, the price is justified? You could check the Private Sales forum for how much 1600Wh MSXes went and judge from there.

Everyone should get that message. The certificate is now "bad" after all. We mods have contacted "The Boss" and are waiting for this to be fixed.

Definitely. It's a Gotway clone design that breaks down as they pump more power/current through it than ever before. - Could it be that capacitor suddenly discharged and burned that hole into the board? Is there a timeline of what failed first? The wheel cut-off, and then you could hear the popcorn crackling which were the mosfets. So what failed in which order?

You're completely right. But this has been like this forever with EUCs, and I don't think it will ever change You would think "Look at the maximum current/voltage/whatever this thing could produce, and let's use components that can take more" would be a no-brainer. But apparently it is not. I don't think they (all of them!) are cheap, they simply don't understand (on some level) that things should be done differently. Right now we have "Usually it just overheats and stops the rider before anything actually fails" level of design, and I don't think the Chinese manufacturers see this as anything but a successful design.

I am speaking for myself For quite a lot of my typical rides, the range wouldn't cut it (not by much, but notable). As a secondary commuting wheel I would definitely love an S18! It just wouldn't work as my only wheel. As it wouldn't for speed riders e.g. That's all I meant. Enjoy your commute, it seems perfect for that.

Slightly "useless" (both the slightly and quotes are important) as in: You buy it for the fun and looks and novelty of having the best suspension (for the foreseeable future). As your only wheel or as a wheel with a dedicated "serious" purpose, you would probably get another ("more reasonable") model with more speed, range, power. To me, the S18 is a "you don't need it, but you sure want it" wheel. Like buying a sports car or something like that. Don't get me wrong, it's only a question of money why I'm not buying an S18, it's sweet.

Awesome! And congratulations! If you need help hiding wheels from the wife, try this true and tested trick:

I hope you ordered both The S18 is a sexy wheel (if slightly "useless"), I do understand you. No regrets!

Oh! Thanks!

edit: That's not the EX, but a fan build of a suspension wheel. - Do you guys think the interior of this prototype thing hints at the interior design of the EX? You think it will be similar? It has quite nice separate compartments for the board and each battery, and also has an uneven weight distribution (2 packs on one side, one pack and the board on the other). Also if anybody can explain what we are seeing with the split shape of the suspension holder...

Finally some proper high pedals! At least wait how this actually feels to ride before you complain guys

Gotway EX added. The top three are now all brand new 2020 wheels!

I think a lot of people are in your position Hello @travsformation The MSP is as great as it ever was, but the Sherman blows it out of the water in so many ways. If only the bad 10% of the Sherman (its flaws) were not there... it would be no contest.

Dented where? The lower front corner?

It wouldn't balance relative to the riding surface (maybe in effect, but not by design). That's not what I meant. It would self-balance relative the the plane perpendicular to the direction of the strongest "downward" acceleration (not real downward, downward as in the rider is pushed into the wheel). Usually that direction would be gravity and it would balance relative to the true horizon, but in banking turns or loopings that plane could vastly vary. E.g. if you ride fast through a banking turn, the plane would temporarily be (almost) parallel to the surface you are riding on, and in a looping the plane would do a 360° rotation. You just need to be fast enough (enough momentum) so you are pressed onto the wheel for this to work. So if you used that (constantly varying) plane as reference, the wheel could behave like any other vehicle that is not dependent on how the true horizon. You can do loopings, you can ride banking curves without the wheel switching off due too much sideways tilt (because from it's perspective, there is almost no sideways tilt). It would behave like any EUC except when gravity is no longer the dominating force. That can be in banking turns/loopings. And I think it would have to tilt the pedals if you accelerate forwards (tiltback) or brake (tiltforward). Basically the pedals would try to "fight" you or indirectly follow the terrain contour. Which may actually be good, you could exert more power on the wheel this way? Does that make sense? TLDR: The net direction that pushes you against the wheel is used to define what (constantly varying) horizon the self-balancing uses. Usually that's gravity pointing into the ground, resulting in the true horizon, but not always. - It will probably indeed go crazy from bumps, though, so I'm not sure if this is practical. But I wonder if in theory this can work.

And the costs for the bigger battery. It has 3 battery packs instead of the usual two packs in 1800Wh wheels (Nikola, MSP, MSX). I think they may need to reduce their typical margin/planned price a bit to compete with the Sherman pricing. Good

Just a sensor good enough to precisely measure gravitational and yaw accelerations independently. If that is possible...

"Horizontal" compared to what? This is my idea about that: Plausible?

Is there a sensor that allows you to measure the acceleration force (normal force as far as pushing the wheel into the ground along its yaw axis is concerned) and ALSO the (always pointing down) gravitational force? Because if you have both, you could switch the wheel off only if a) the angle between gravity and wheel is too much (e.g. 45°) AND b) the normal force is too weak to push the wheel into the ground This would allow you to ride "banking" turns if you have enough momentum, right? The wheel would only switch off if it is tilted AND too slow to keep going. (Probably the cut-off angle would be dynamic, depending on the wheel tilt and yaw acceleration). That's what I have been thinking. Sideways wheel tilt (riding a banking turn) or forward/backward wheel tilt (riding a looping*) would only switch off the wheel if it does not have enough momentum that would allow it to keep going. If such a sensor exists, would that work or is there a conceptual problem somewhere? [* The self-balancing of such a wheel would have to be relative to the yaw acceleration direction instead of the gravity direction. but then you could ride a looping, right? I always wondered if that would work.]

8A is now slow charging... I like this new generation of EUCs
