Just learned about this. That's a bit lame. Did Inmotion go with the wrong battery supplier, where you aren't even supposed to charge the cells fully? Are they just more careful and this applies to all cells? What about cell balancing, is it guaranteed? Plus even a little extra range loss on a (fast!) wheel that needs all the battery it can get

Thanks! By the way, I can't say enough good things about your disassembly articles and the great photos! Very much appreciated! For example, the only wheel weight numbers I really trust are the ones where I see a photo you made of the wheel on your scale.

Semi offtopic: some really nice wheel comparison pictures in the EcoDrift teardown! Sherman-S (S22 Pro on the right, S22 in the middle): With Sherman-S, V13, and 14 (or 16?):

He is, but he very rarely visits nowadays. Try via his Youtube channel, or (best approach I think) on Facebook, he seems to regularly post in this group: https://www.facebook.com/groups/ElectricUnicycle/ There surely is a Marty-specific Telegram group or so, but you have to ask someone else about that, I know nothing here. A video about the Commander Pro is coming up, though, so you just need to wait a bit for his opinion.

Crazy, but why not! I like the thing! It seems to be very silent and not "whiny" like so many other small electric motors (well, they are not really small here) Does it say somewhere how many Wh the battery has?

Note it's the last (third) item on the first page, not the second item which concerns hoverboards, minipros and so on (2 wheel self-balancing vehicles). I don't have an insurance, and I don't think I could get one if I wanted to. I'm certainly not paying for insurance that may or may not pay out. The point of this is so you could say "This here says these are not covered by law" and use it to your advantage as you see fit.

Not sure that's true. Anyways, there is an (older) legal opinion that says EUCs are not covered by German law due to a legal loophole (politicians too dumb to cover vehicles that are self-balancing and have only one wheel). See this: Grosskopf_NVZ_2015_531.pdf (legal opinion, very hard to decipher) and this: informativ_76.pdf (this is good because it is literally from a police info brochure and compactly says that EUCs are ok). No idea if that works or is valid (supposedly someone used that argument repeatedly with success, but I don't know any details), but you can always use it as an excuse "I thought I'm ok", ""Well I guess I'll stop riding then" (lie, this is the thing to say to make a difference between being let off scot-free or not) etc. to get out of potential trouble. So this approach can only benefit you. Personally, I do ride bike paths and mountains and trails and through the countryside where there are no police anyways. Passed them a few times in the city. I believe the combination of not riding like a madman/slowing down near police (if it looks like you are going 20kph or less, they might not see it as a problem or may think you are like one of the e-scooters that are good) and surprise/not being right where they are (how do you stop a EUC rider who didn't hear you with the helmet and all that noise? Not that easy) will be enough unless you are very unlucky or they expect you coming (like some traffic stop thing). Your best defense is being gone before anybody even realizes what is going on. EUCs are quick and stealthy. It's up to you how much you want to stretch the unclear situation. Avoid places with guaranteed police presence, I guess. If stopped, be nice at first and see if you can convince them that you (thought you) are legal, and nudge them (EUCs are heavy and you need to constantly maintain the battery to prevent damage, bla bla) if they indeed try to confiscate your wheel (I don't think that will happen unless someone has a bad day, especially if you have the good excuse that you might very well be legal... ahem, are legal as far as this piece of paper says).

(This has been split from the original thread because it was not exactly relevant there.)

EUCsale https://eucsale.com/euc-transport/ should also be good. Denis Hagov (the guy behind it) has quite the Youtube presence https://www.youtube.com/@TheHagov/videos I'm sure there are other EU shops selling Veteran wheels, but I know none.

If you are looking for a seller, we have a forum for that. Feel free to ask and check there. https://forum.electricunicycle.org/forum/74-where-to-buy/

Owning a EUC is perfectly legal, and there is no basis for stopping anybody from getting one. People order from China (often sellers with EU warehouses, but often enough real imports) from a lot of European countries, and I haven't heard of a single case where it didn't work out because of customs or such things. So you can buy from anywhere that will ship to you (which is why you can't buy from the North America based sellers from here). Naturally, buying from a EU shipper makes sense because then the import has already happened and you don't have to worry about it. I don't believe there are any EU-internal custom checks. Single market and all that. Any EU distributor sends you your wheel and you'll get the package without anybody else checking it. Anyways, it's moot, no basis for stopping the package if someone were to check (and know what they are looking at, which isn't going to happen). There's like 3 levels of why you won't have a problem there In Germany, riding in public is either a grey area or not allowed, depending on how you want to see it. And whether that matters in practice is another question. It's unrelated to buying a EUC though. (The Bulgarian seller is https://myewheel.com/ with an "e".)

What does the "high speed mode" do? Reduce some safety margins?

Honestly, while usually the first option would be "Send back to seller, this is only two months old!", an "authorized third party" sounds very good to me. Both options are good.

Here's another quick disassembly video by EcoDrift. From this article: https://ecodrift-ru.translate.goog/2020/07/23/inmotion-v11-razbiraem-ch-1/?_x_tr_sl=ru&_x_tr_tl=en Part 2: https://ecodrift-ru.translate.goog/2020/07/25/inmotion-v11-ves-dvigatelya-i-prodolzhenie-razborki-ch-2/?_x_tr_sl=ru&_x_tr_tl=en Note you don't have to remove the board (on top) or disassemble the motor or any of the other parts (they literally put the wheel into its pieces), you just have to get far enough to remove the battery packs (behind the side covers) and put in the new ones and screw everything together again. Decide for yourself if that's something you would like someone else to do, or if you would do it yourself. You can also loo up "Inmotion V11 teardown" or "Inmotion V11 disassembly" etc., I'm sure there's more, until you are certain enough about the procedure to decide.

Please take this seriously - compromised batteries (apparently they are compromised) can catch fire. Is there a way for the seller to do this for you? For a 2 months old wheel it should be their job to fix any defects. But if you have to do it yourself, it's essentially disassemble - unplug old batteries and plug in the new ones - reassemble. It's not rocket science (but tbh still the sellers job to fix this), just a bit intimidating if you've never done it before. Feel free to keep asking questions here before and while you replace the batteries, should you do it yourself. Maybe a third party can do it for you as well.

Wide rim is wide! Does that need a special tire size? Or just the regular 2.75 - 14 like all the others? I still don't like the ground catchers on this wheel - the fact that there is so much stuff below pedal height. But I guess it might not be a problem in reality. A less obstructed tire would be great though. Like on the V13 or S22 in the comparison picture above.

They got a bling bling-ed S22 and an orange 16S, too.

Found on reddit. Someone got one of these golden 16X. Looks... shiny.

@Freestyler

Works now!

Yes. They always worked properly.

Range is going to be the same between the Commander Pro and the Sherman-S. 3600Wh is 3600Wh no matter how you configure the battery internally.

Yep they don't work for me either. @MrMonoWheel

I think $4000 instead of $4500 and up counts as cheap nowadays

4p seems to be the threshold where it is more or less impossible to overpower the wheel (except at speed, where that is always possible, just go faster until it is) for any sane rider. Master and S22 are 4p, as are so many other performance wheels. So whether the Commander is 6p and the Sherman-S 8p doesn't really matter in my book. It's enough either way. 134V gives more peak power from the same battery configuration than lower voltages, so if anything higher voltages would be an argument that you need less p's to feel good about them being enough. Not that it matters when you already have a 6p battery.
