What happen with the traffic behind you when you go 31 mph and then come to hard stop without notice?

it wouldn't tell you to 'get' get off in that situation... the get off warning only triggers for a overload/overlean not for a over speed situation  so your little senario won't happen in a normal traffic situation unless your driving like a moron!

im 6.4 and 15 stone and iv NEVER  over powered my v10 so can we stop making out like this is a common occurrence when the truth is it's really not for the majority of riders..

Does "Please get off" really force you to get off, or is it a request? There's a big difference.

What matters is the actual behavior of the wheel, not the wording of a translated warning message.

Big tilt and only shutting down the wheel will fix

knowing your wheel is the biggest safety feature and riding accordingly so you don’t overpower it is the key

The main reason I like Inmotion is their attention to making the device safer than the other manufacturers.  For hardware, they've typically shown more attention to waterproofing and the new V11 presentation highlights the increased number of mosfets and a more sophisticated battery system which can operate even if one pack has failed.  They also seem to have taken lighting more seriously, for both forward and rear directions.   On the software side, they've typically had a more conservative performance curve while the batteries are being drained, which I appreciate.  On the human side, they've treated max wattage overpower situations AS THE BIG DEAL THEY ARE by purposely inconveniencing the rider to slow down and stop.  (This might also serve the dual purpose of allowing the electronics time to cool.)

We already have other manufacturers emphasizing other things.  Let's acknowledge that safety is one of Inmotion's strengths, and we need at least one company prioritizing that. We don't need another Gotway. 

If only I could have put it this elegant as you done here. 

It all boils down to don't make Inmotion into GW. If GW is what you want the buy what they supply. If you want a different design philosophy Inmotion is there to supply it. Now they are building a stronger version of the V10f but it still have put tide comfort and safety over speed. 

I am very happy to put my vote in where I think is the right approach. I am so looking forward to get my V11. And yes GW is never going to be in my persuasion as I do not think the GW approach is the right way to go about. Unless they stop the race of top speed and start to look into safer and comfortable rides.I am perfectly fine not to own a GW wheel.

But let discuss the video, agreed that Kuji did accelerate hard, but the wheel force stop at 28.7 mph.

  1. So, if this is the physical limit of the wheel:
    • Someone said if accelerating gradually, we can reach higher speed, assumed 31 mph (or possible higher as Inmotion said they will increase top speed), so are we riding on the wheel physical limit now? No buffer? Is it dangerous?
  2. If this is not the physical limit of the wheel:
    • Why not just slow down instead of force stop.

No wheel (other than GW) will ever let you ride anywhere near the physical top speed of the wheel. There is always a decent speed buffer available.

 Accelerating like that will plummet the battery voltage way down immediately. EUCW logs on the Euco’s MSX vs MSP uphill acceleration comparison shows a full battery getting down to something like 15% in a second. My guess is that in Kuji’s acceleration the busy battery of the V11 engages the speed limit much earlier than 28mph, but it takes a while for the tilt-back to overcome his supernatural lean.

 

But what raised this discussion is the wheel’s overpower warning behavior. Comparing stepping off to replacing a fuse or faceplanting is something I don’t really get. KS has no problem telling the rider about “Overpower” and letting the ride continue. If Inmotion would first warn about the overpower, and if continued for two seconds or more, then I would accept stepping off as a reasonable course of action. And it damn sure wouldn’t make the V11 a GW, like some people seem to suggest. But having the first warning already a “get off“ isn’t right in my mind, no matter how far the threshold is.

 It’s not about rider weight either. If a 70kg rider can reach the limit when accelerating on flat ground, a 100kg rider doesn’t have to be out-of-this-world stupid to reach the limit when accelerating uphill. Or a 120kg rider when off-roading. It’s been made clear since day one that the V11 has not been designed as a peaceful cruising wheel for sub 100kg riders. IM has said word to word that they are making an off-road capable high-powered wheel for professional riders. In order to fill those shoes the wheel must behave as expected, especially when nearing the limits. Expecting no-one to ever reach the power warning threshold of the wheel is absurd. And they are not necessarily “holding the phone wrong” if they do.

This would be the ideal way to do it. I would like to wheel to shout "RELAX!" at me if I'm about to overpower it so that I could tone it down a bit and avoid stopping. However, by nature the power demand usually doesn't come slowly. Very difficult to ask 3000+W of power doing it slowly. Maybe on a steep hill. Like in the Kuji's video the "pre-warning" wouldn't have had much reaction time. Hopefully they can extend the limits a bit to allow 2-3 seconds before asking to step off and maybe trigger the pre-warning a bit earlier to let the rider know they're approaching the limits.

Lets bring up this classic acceleration test from Kuji (I marked the timestamp).
18XL vs MSX.

Nobody ask V11 to behave like a Gotway.
But is expecting similar performance to 18XL too much? 18XL is a 2 years old wheel, with very similar specs to V11.
I didn't see it ask Kuji to get off the wheel, the wheel slow down but still ride peacefully after over power.

But again, we're arguing over a very short clip, nobody know for sure if V11 will behave like V10F when over power.
 

I think KingSong also has an overpower alarm separate from speed and battery alarms. But I don't know what the triggers are. 

But this video shows something about the acceleration tests. If you pause the side-by-side footage at any point you can see the difference in lean angle. The acceleration tests are more game of chicken than about what the wheel can do. Which brings me to another point. On that video Kuji got times of 5.33 and 5.60 seconds (speeds 50 km/h and 48 km/h). On the latest V11 video I timed 4 seconds until the warning and the speed of 46 km/h. Looks like Kuji has gotten better and braver at leaning, which might explain the alarm also. The earlier video doesn't show power usage on the app overlays, which is a shame. Would be interesting to compare and see how the alarms are triggered.

KS do have overpower alarms. 

You can see it here in this video of KS16X going up steep inclines. But in this case it is trigger not combined with speed. 

Now I see some compare to MSX here. The MSX is not fast of the start nor super at braking. 

I do hope @Kuji Nakano soon share some insight to how the wheel over all is and how it performs. On the other hand we do know he is using a test firmware that Inmotion is trying to look into possibility of raising top speed limit. A speed they didn't aim for in their base design. I just hope they don't ruin the V11 in trying to please GW buyers.

I also hope we soon see some other reviews as I like to see a more like my daily ride style would look like. I am not riding like Kuji. But I would hope it is good at braking as it is important to me. I would rather be able to brake hard then navigate than trying to accelerate out of a situation.

How do you know that? From the early rumours on it was supposed to be faster than 50 km/h wheel. It was actually a surprise they announced it at only 50 km/h. You have know idea what type of motor they used and where the limits are. 16X is a totally different story with a motor focused on torque and smaller diameter. 18x3" tire and their new in-house motor and new control board could easily be capable of same speeds as Gotways with similar specs. They all use just standard parts, I've never seen any real reason for a Gotway with 84V, 2000W nominal motor, 20s6p battery and 12 MOSFETs would be more powerful than another brand with 84V, 2000W nominal motor, 20s6p battery and 12 MOSFETs. V11 has only difference at the battery with 21700 cells. 

It's all a question of how much reserves there should be and I believe that is what they are testing now. I don't see any reason it will be ruined if they allow it to go faster. We get your position as it's been stated quite frequently. You can always set the limits lower. Personally I'm probably not going to go any faster but there are some people who like more speed. Why deny them the opportunity? This hobby has become too big to control. We are not going to stop people from doing stupid things. They already have the wheels to do it with if they are going to.

Not true. When they announced that they are working on an 18" wheel with suspension last fall, they said that the top speed will be "more than 50km/h, probably 55km/h".

When they introduced the wheel with 50km/h top speed, people naturally asked for the top speed they had been expecting to see for months.

I have been in contact with Inmotion discussing inputs and feedback. So I can only say that from those they didn't aim for more than 50kmh. You can see that also from their launch presentation.

Don't you mean "RELAX ... DON'T DO IT ... WHEN YOU WANT TO SUCK A CHEW-IT ... RELAX ... DON'T DO IT ... WHEN YOU WANT TO ... OOPS, TOO LATE!!!".:roflmao:

For riders who "never" have overload with V10/V10F please read this.

 Riders mix two words

overheat = just too many heat ( we not talk about this V10F fan if work make relatively good job)

overload = thats we talk about its just stop push lift sensor or on/off jump back to V10F and continue ride. (overload is trigered "high" current drain in 3 secons)

I've been using v10f for past 6 months nearly every day and never had a warning you are writing about. Maybe because I weight 71kg. 

I am like you enjoy you V10F.

My girlfriend ride my V10F and never experience it too but she ride like lady and she weight is XX Kg (censored).

(joke/irony/satire start)

Dont worry once you be lucky and you v10F force you to stop. This day come maybee when you overtake cyclist or you try run away from dangerous situation (tornado ,car, cyclist) or when you try ride out 3 angry dogs what want eat you face. You panic push hard and hear it ,overload please get off.I hold my thumbs for you.

(joke/irony/satire end)

The more we discuss in the pre-production phase and we find controversial places before the release.

The better the V11 product will be and I hope we will agree that we all want the best V11.
Because once V11 is made, the only thing that can be changed is the Firmware, and it is not omnipotent, it will still be limited by the capabilities of the hardware. That is why I thank everyone for a positive and quality discussion and I am glad that some of you share this opinion with me on this controversial feature.

I have a question. What is the definition of a “professional rider”? I didn’t know our hobby had those. I know we have people that are really good and talented but I didn’t know we had professionals. How do you become a professional? Who determines that you are in fact a professional? Do people considered professionals get paid for it? I’m learning something new about EUC’s every day.  LMK. Thanks.

i can assure you there's no mixup here, I live in england so overheating a wheel here is near enough impossible lol... theres a clear difference between overheating a wheel or overloading a wheel and i stand by my statement of never ever having overloaded my V10
