The times don’t mean anything else than how secure the wheel with it’s current setup feels to this one rider on that specific day. It says absolutely nothing about how fast you’ll want to or be able to accelerate, or how effortless it feels. 3 Link to comment Share on other sites More sharing options...
GPW Posted May 19, 2021 Share Posted May 19, 2021 Yeah, I wouldn't overanalyze that data I posted. Hoped my caveat that it was "not a scientific answer by any means" might preempt. It's just one guy attempting to max out acceleration on different wheels - many caveats apply, take it for what it's worth. I certainly won't be submitting the data to a peer reviewed academic journal for publication anytime soon ;). Link to comment Share on other sites More sharing options...

Which ever way you look at it, it's still a matter of centre of gravity. I'm not quite sure what you mean but it sounds like you are saying there is an alternative way to accelerate. But I think it's just an alternative way to cause the centre of gravity to move in front of the axle. You wouldn't stay on the wheel if there was a way to get the wheel to accelerate without you falling forward and the wheel catching you. 1 Link to comment Share on other sites More sharing options...

You wouldn't stay on the wheel if there was a way to get the wheel to accelerate without you falling forward and the wheel catching you. Man, you look experienced, you maybe have yet to go in soft sand to see that accelerating can be done by leaning or torquing. The outcome of those 2 way to call power are different (what is different than accelerating, accelerating is a consequence) : If you lean in sand, you'll "face plan" (well at 5 kph) before to you got enough power to overcome the increased resistance of soft sand. What you have to do instead is to keep centered your gravity and constant speed (slower, easier), but twist the wheel forward, to push a lot more of power against that resistance of soft sand. I guess is the same in full acceleration test, leaning a lot expecting the wheel to follow is risky - so you naturally end leaving some room. In the other hand, you can twist forward hardly your wheel, then lean to keep the balance, as a reaction. This way you might get Adam's wrongway acceleration numbers....

Firstly, do you want to achieve the absolutely fastest acceleration by any means necessary, or do you want the acceleration to be effortless so that a smaller lean would cause a faster acceleration? Because they come from different parameters of the wheel. So you may need to think it through more closely than just “maxing out the acceleration”. If you want to accelerate as fast as possible by any means necessary, you need pads that make you feel secure while leaning forward like crazy on an EUC that has huge amounts of absolute power, the kind that the MSP and EX.N are famous for. But accelerating like that takes a lot of effort. If you want the most effortless acceleration, you need a small tire diameter. Simple as that. The riding mode affects this as well, so be sure to stay away from the hardest riding modes. Inmotion has the best adjustability, but every manufacturer has a signature feel that you need to familiarize yourself with in order to choose the best match for you. The Mten3 might have the most effortless acceleration, but it comes with several great costs. So you need to pick the smallest tire size you can live with. But looking for a wheel that is best on one aspect only is a bit narrow minded, and may result in a crappy or short lived overall experience. All modern EUCs can accelerate like crazy, and choosing suitable pads and a soft enough riding mode will make any wheel accelerate with a reasonable amount of effort. But a lot of other aspects are simply not available on some wheels. 1 Link to comment Share on other sites More sharing options...

I’m not sure if the Center of Gravity is a familiar parameter to you, but it’s basically all the wheel sees. You can’t twist the wheel forward with your CoG on top of the axle, since as soon as you do that the wheel accelerates in front of you and you are no longer on top of the axle and the wheel will brake (or reverse). You can confirm this by stopping in front of stairs that go up. If you only twist the wheel with your CoG on top of the axle, you’ll fall backwards (the wheel will reverse) right away. The only way to keep the wheel accelerating is to have your CoG in front of the wheel’s axle. The reason the lean and the twist feel so different is only in the amount of support and control you have. Quote If you lean in sand, you'll "face plan" (well at 5 kph) before to you got enough power to overcome the increased resistance of soft sand. What you have to do instead is to keep centered your gravity and constant speed (slower, easier), but twist the wheel forward, to push a lot more of power against that resistance of soft sand. Since the only way for the wheel to sense your movements is the tilt of the pedals (and shell), how does the wheel know which method you are using at any given time? Quote you can twist forward hardly your wheel, then lean to keep the balance, as a reaction. You make it sound like you would order the wheel to accelerate by twisting the wheel, and then lean forward to stay on with the accelerating wheel. In reality it’s the other way around. The wheel is the one doing all balancing front to back. If your CoG doesn’t match the acceleration, the wheel will adjust the amount of acceleration based on that, not the other way around. If you want to test the amount of balancing you can do by yourself, step on a wheel that’s powered off. Everything else is done by the wheel.

In the other hand, this theoretically gave us a fast accelerating wheel, ~3.0s for this V12 "16X 100V"?? May InMotion give the High Torque/High Speed choice as Gotway? As seen with them, HT run cooler and have a better range. Bonus. I think Camenbert has a good point here. Doesn't it seem like an odd design choice for a 16" wheel to be pushed in the direction of speed instead of torque? A smaller wheel has inherent advantages for acceleration/torque along with the mentioned benefits of cooler running and better range. I was under the impression most people would only feel comfortable at 40+ mph on an 18" or bigger wheel because of the additional stability a bigger wheel provides. On the current small 14" wheel I have, the MCM5, there are plenty of comments on 28+ mph being MORE than fast enough. Wouldn't the V12 find it's niche better as a super snappy well built medium size wheel with solid range instead of going for outright speed where it really can't compete? 3 Link to comment Share on other sites More sharing options...

Actually, hadn't intended to express any personal view or wholistic appraisal at all. I hoped only to shed some light on a narrow question with a relevant albeit limited comparison from Adam's videos since I happen to have just sought the info out of curiosity. I had no intention to assert what wheel was "best" outside the scope of that narrow question, or even that those data points served as any definitive evidence within the narrow question. If you want to know what wheel I think is best? Well, I will most likely vote with my wallet. See the V12 as a huge upgrade over my 16x for a whole variety of reasons.

Speed sells. You can always force more torque out of a wheel, by going "YOLO just use more battery power lol". But you can't force more speed out of a wheel, the motor is wound for a top speed and that's it. So you can always change the firmware to give more torque at the expense of efficiency/range, but you can't increase the designed speed after the fact. I'm not saying I'm liking it, but these are two arguments why manufacturers might in doubt design for speed. I personally would love a super torquey wheel with a big enough tire (like the V12's 16x3) to be comfortable and stable offroad. 2 Link to comment Share on other sites More sharing options...

You act like 100v speeds + 16x3 tire is some weird new thing. It's just an iteration of the formula established with the 100v Nikola, one of the better-reviewed and better-selling, non-entry-level wheels from a few years ago. (Both Marty Got Backe and MickEVX Mouse claimed that it was "the best" to buy for a span of time.) Regarding the tuning, there are lots of riders who start to hit beeps on their wheels that max out around 30 mph and therefore want a little more from their next wheel--not because they're suddenly speed demons who want to go 40+ mph, but they want to be able to approach somewhere in the 30s mph with some headroom to spare for safety, so something rated at 40/42 mph sounds great. (I'd wager that the number of riders in this category are 99:1 against those who will actually ever cross the 40 mph threshold.) And a wheel wound for top speed of 40/42 mph makes more sense for them than one that's wound for torque that tops out somewhere in the 30s/only 5 or 8 mph higher than their previous wheel.

Popular Post Mike Sacristan Posted May 19, 2021 Popular Post Share Posted May 19, 2021 The Nikola Plus has a free spin of 85kmh and the 5 beeps come in at 64kmh and 100% battery. They will trigger at 63kmh though since you won't be at 100% battery and 64kmh at the same time unless you are blasting down a steep hill. Highest speed I have seen on a Nik+ is 72.3kmh by my 100kg friend riding seated. Or 75kmh by my friend crashing. Typically the Nik will run out of torque and over lean at around that speed. I normally hit the beeps on every ride despite having a 2664Wh Nik which is why I upgraded to the EXN. Sherman, Nikola Plus and Monster speeds seem inflated by around 6-8% compared to the EXN. 70kmh = 65-66kmh. My EXN has a free spin speed of 95.x kmh and the 5 beeps kick in at around 73kmh at full battery and 66kmh at half battery. 61kmh at 80V. The V12 free spin speed does indeed sound very fantastic. I wonder if the speed is as inflated as the V11 was where fancy mode 55kmh was 51kmh in reality. The Nik is notorious for skipping through magnets in the soft mode. Less so in medium and much more difficult in hard mode. An MSP HT with C38 magnets is a chore to get to skip and requires a heavy rider and a heavy drop... until you hit 30% battery or around 85V. Then you can start to pedal dip it with heavy accelerations at around 40kmh but it will only speed beep you at 51kmh and Amp warn you after you have fallen at 45kmh. An EXN is hard to skip magnets on unless you torque it at above 60kmh or slow speed torque it with aggressive pads on the hard mode... especially backwards (back heavy). Riding in sand or dirts is a matter of accelerating gently to succeed or like an idiot to burn out... and twisting only serves to correct the wheel. With pads it might seem like we can torque the wheel by twisting but that is because we can apply forward pressure to only one pad and it will translate to forward pressure for the entire wheel. You can twist left and right infinitely and maintain balance without going forward. But you can not lean forward without applying forward torque... or do an extreme forward lean and apply too much torque with so little friction that the wheel will simply do a burn out and you fall... like I did on wet artificial grass the other day... with locked in pedals and spikes... now I know what it fees like to get punched in the solar plexus and kicked in the balls at the same time. Usually it has been one or the other. 6 Link to comment Share on other sites More sharing options...

This describes my interest in V10F -> V12 perfectly. I appreciate the safety-conservative design and build quality of the V10F, can't see myself using a Sherman anywhere near its potential, am put off by GW/Begode's poor build quality and lack of safety features, but am just not happy that I'm frequently hitting beeps with V10F (especially when mixing up with traffic where my safety depends partly upon keeping up with the flow), and that I can easily run out the battery far from home. V12 seems to tick all my boxes. I am suspension-curious, but frankly I think the lack of suspension is what's keeping me from wanting to go stupid fast. Rough pavement, potholes, moments of inattention: I respect these threats, and suspension might push me firmly into the Darwin zone of risk homeostasis. I mean, already I don't always gear up completely, and that's another thing that keeps my speeds down. 12 Link to comment Share on other sites More sharing options...
