Your comments really helped regarding the ACM whine and they show it's a great EUC overall. I'm still not fully decided (the V8 is just so nice too) but it's probably going to be the ACM V2 @Marty Backe edit How long to load the ACM? Off to looking at more youtube vdeos of the ACM and V8... How long to 'load'? Do you mean charge it? If that's the question I'm not sure because I usually stick it on the charger and forget about it until I next wonder by the wheel. Good luck with your decision. I just posted another MSuper & ACM ride video in the Video thread. Link to comment Share on other sites More sharing options...

For a EUC-newbie: You have to know that you mostly will never drive your EUC to 0% Batterie...(for security reasons!) i for myself never go under 20%..and if you want a real, real Long Batterie life, you dont load it to 100%...the best is just to go to 80-90% for Batterie lifetime...so Keep that also in mind when making a decision! Aaah: And more Watthour does not just mean more range! It also means more safety, as more watthours normally means more parallel Batterie Systems in the wheel, so less amperage for each System, so less stress for the batteries...... I would go for the ACM V2 and that as 820wh(Minimum) or better the 1300wh Version... (1300wh especially when you are very heavy!) Forget about this wine Problem....you even dont hear it anymore after a time ....and it is not so loud as in some video's where the microphone is near the wheel!

I don't know if I personally would trust an ebay seller, but maybe they are ok.

You and @Marty Backe calmed me down a lot about the issue. -- Now I'm confused: the difference between Gotway ACM and ACM V2 is the number of mosfets (6 vs 12)??? (more better against overheating) Never seen an ACM V2 with 1300 Wh. I believe an ACM 1600 Wh is coming but it's not a V2? Or is 1600 Wh some msuper variant?

What is this, for example: http://airwheel-eu.com/gotway-acm-3-16-1300wh-12-mosfets-35km-h-130km/p-207379c999 All these Gotway/ACM models are confusing, what's the deal with that?

Once you've been around all of these wheels for awhile, the naming conventions and numbers start to make sense. For the ACM, V2 designates the change to 12 mosfets. For the MSuper V1, V2, and V3 refer to the versions, each one being physically different from the previous. There is always going to be a better wheel just around the corner. EUCs are no different than other product categories. It's best not to always chase the latest, but buy what you want now and let the future work itself out.

Marty Backe Posted January 19, 2017 Share Posted January 19, 2017 I just rode my ACM V2 (820wh) for 23 miles along the beach fighting some pretty strong winds. Battery was at ~25% no load (<15% under load). Temperature was in the low 50's and my riding weight is 170 pounds. Most of my riding is in 70+ degree weather and I've been getting a reliable 30+ miles from the ACM. Colder temperatures and strong winds will reduce it.

US69 Posted January 19, 2017 Share Posted January 19, 2017 look here for the existing versions: https://www.speedyfeet.co.uk/collections/electric-unicycle Unfortunatly the german shops dont have the 84Volt versions(1300,1600wh)...and i read somewhere they dont get them in the forseeable future... speedyfeet is higly reputated... but btw: buying on aliexpress is one of the safest options... the seller gets the money only after you confirmed the good/product to be received! called buyer protection...i for my part have been happy with my two wheels from there. but i regret: for a first time Euc with less to none technical knowledge it is always better to have a good warranty partner.... so if you you want a stronger ACM....i would definitely vote for speedyfeet!

So the higher versions are even more powerful. Do I even want that? Is there anything to know about the difference between 2900mAh and 3500 mAh batteries (loading time, longetivity, whatnot) or is that merely technical specification and you wouldn't know the difference from the outside? @Marty Backe Thank you for the continuing information. So anything that explicitly says 12 mosfets means ACM V2. This confused me, I wondered why there were no higher capacity ACM V2s when there were ACMs. The speedyfeet.co.uk website does not mention 12 mfets tough so I hope you're lucky (and me too, would order from them if I take the 1300) and it's 12. The 1300 looks different in the pictures too (metallic sideplates instead of all black-ish) I wonder why. Must be a secret of the Chinese factories and whatever goes on there. I actually like that (the color). And the price is only 100 more which seems like a no brainer. Also very good to hear your performance data. I can't say I know what I'm going to do with the EUC because I never even tried one. But if I'm using it that would most likely be for hours instead of something like 30 min rides, that's for sure. And my guess is, if I'm going battery-eating mountains (not sure if that will turn out to be the most fun thing to do with an EUC) then higher capacity battery will make a difference between "can I do this?" and not even thinking about it. You went higher too in the end and I take that as a good sign, your long tour videos are inspiring. I will do some weight tests to get a feel for how much the different versions weigh, I don't want this thing to get too heavy. edit: danke! @KingSong69 yea for so much money a good return/warranty/repair partner is quite important. And their yt videos are very good. Link to comment Share on other sites More sharing options...

I find the ACM to be too wide already (680wh version). It's my favorite wheel, but not as comfortable to ride as the Ninebot and I think that's due to the width. I definitely wouldn't want it any wider. Link to comment Share on other sites More sharing options...

It is just about a bit more than 1cm wider at each side.....if you want you can better this Situation like i have done on my "wider" MSuper with not using the original rubber sidepads, and just using Standard foam....look here: If You use the Standard foam instead of the the thick original rubber i would guess it is just a Little tiny bit wider.....

I instinctively liked the Inmotion V8 because it was relatively narrow, so this is good to know (will most likely go ACM though for battery capacity considerations). Why is the ACM your favorite? Can you describe what it is you like more about narrow wheels? Are you standing more naturally? How tall are you (if I may ask)? @KingSong69 Are you a distributor or something? You know so many details + you do modding Good to know they are slightly different shells. Link to comment Share on other sites More sharing options...

I would maybe wait for your opinion if it's not too long. <snip> 2 day shipping turned out to be a bit of false advertising :-( But I have a tracking number so I'll have the wheel on the 26th for some testing on that weekend. Since the motor is the same across the different ACMs I can't believe that it'll be louder. I have the MSuper V3 and last weekend I rode along @swvision who has the V3s+ (84 volt model). I didn't do a test but nothing jumped out at me. Two MSuper's and an ACM were cruising all over the place and not once did I even think about noise from the motors. You can hear the whine from the Gotway & Kingsong (and others?) motors if you are listening for it. But if you're just riding the wheel whatever noise is there fades to the background and you just don't think about it. A car has an engine noise, but you don't think about that as you're driving about. You should try and meet up with @KingSong69 so you can hear it for yourself.

swvision Posted January 20, 2017 Share Posted January 20, 2017 The V3S+ does have a high pitched jet like sound to it but even that gets negated by the surrounding environment. Honestly, I didn't even notice the sound difference between my V3S+ and the V3 that @noisycarlos was on. Link to comment Share on other sites More sharing options...

If the motor is the same and the noise is the motor tuning, then bigger battery won't change anything. Going to ask the speedyfeet guys if theirs is definitely the V2 version and then I'm going to order the 1300. Thanks so much for all your info!

Ian can confirm for you, but except for the first version of the ACM, all Gotway 1500+ watt motors now use 12 mosfets so that they run cooler.

I feel bad for the speedyfeet guys, didn't want to interrupt their weekend... didn't expect them to do anything before monday. They even gave me a heads up to consider the power outlet situation and what connector cable is needed for that (charger cable has UK connector - I assume any run of the mill figure 8 connector works with the charger?) This kind of customer service (and that insidious rewards program) is going to give them a lot of customer retention. Deservedly. Link to comment Share on other sites More sharing options...
