Looking Extreme - Solowheel Xtreme

[EUC Extreme]

Gotway 18 goes 40kmh. It is too slow. Off-road either speed up almost constantly 30-35kmh. I leave a small resource that turn off accidentally. In this latest video which time it rains. It was very slippery, but I did not let it bother me.

Different applications and needs...

I don't need or search off road specification features. .. 

With Xtreme I wear it and travel like aboard of a Rolls Royce  or a Bentley sensation 

[sunny]

"zugu" you are incredibly pro-Solowheel! 

@vee73 - that last video was awesome, especially the beginning on those wooden planks!

[EUC Extreme]

Thanks. Those planks were really slippery, and I do not dare to run any faster. Even in this speed ring tried to retrieve their own schedules planks at the seams.

[zugu]

"zugu" you are incredibly pro-Solowheel! 

 

​Well .. Solowheel borns with a side aim concept of SAFETY in mind!!! 

Chen told me last week: " First I invented it to solve primarily some mobility transportation ! Now , with Xtreme and forthcoming models we are concentrate on COMFORT !" 

I married this philosophy !

Bear in mind that Xtreme, but either a lot of high power EU, can easily match higher speeds like 50kmh and more if someone program it without limitations. . BUT IS NOT SAFE !!

Imho, obviously exist sports and rally cars ! But they are used for sport activities and it's very rare to see them everyday in a normal traffic city road...

How many cells does the SoloWheel Extreme have? 18? 20? I suspect many who buy an 18" Wheel, recognize a 155Wh battery is laughably insufficient for an 18" wheel. By way of contrast, the Gotway 18" 850Wh, has >80 cells in it, which can provide at least 4x more sustained power.  

[EUC Extreme]

Gotway 18 batteries of 16 cells.
And why not 50kmh not safe?
A motorcycle is driven much harder. Both downfall is as safe, or dangerous.
And I at least urge to get even more speed.
I'll post a short video in which the forestry path to almost maximum speed. 30-35kmh.
The harder I would have liked to run

Most of us do not ride with this much protection, like you! 

 

[EUC Extreme]

Motorbikes can be used for many purposes. Why not, therefore, then these can be?
Now, manufacturers have to wake up that these must be done for different purposes.
Not only is the street for commuting to work.
I think that it is only the beginning.

Vee73,

I like speed as much as you do (tat's why I have a sportscar ) ). BUT, safety is a very big concern for a mode of transport that still needs to get recognized and accepted. The first cars certainly were not ver fast. If the first cars had be capable of doing 200 km/h, who knows what lawmakers would have decided then.

You listed a list of your injuries in another post, most people would not be willing to accept those kinds of injuries just for going to the supermarket.
And you got those injuries even though you are well protected.
And yes, motorbikes can be dangerous too, but I think everyone would agree that it is much easier to become unbalanced on an EU than on a motorbike.
In many of your videos, we can see you falling down. 
I am sure you would not like to falling down that much if you would be driving in the streets of a big city and everyone would see you fall all the time.

I agree that for your kind of driving, the Gotway is a lot better than probably any other EU out there. But you are simply a thrill seeker, most EU riders are not

But vee73 is testing the extremes of the eucs capabilities which is a good thing for someone to do, even if you and I choose not to.

The majority of motorcyclists don't take part in moto GP, motoX or motorcycle trials but loads do and there are huge numbers of specialised machines made for those sports. However originally all those sports took off using mildly adapted road machines.

​COMPLETELY Agree with you!! 

Vee73 is my offroad "idol" , me too love speed ! But street road injuries by a fall could be a dissuading element 

Asphalt is hard..... 

[MarkoMarjamaa]

I've broken my collarbone winterkiting(kitesufing kite and snowboard)  even with "motocross-like" armor. The surface was a centimeter snow and then hard ice like concrete. I didn't jump, just lost my balance when making a turn. Then I made a decision to avoid that kind of surface situations. It was not worth it. I prefer to fall on soft snow or water.

I don't intend to wear any armor while unicycling and I don't intend to hurt myself.

​I just wish I had the space and room and most of all the EMPTINESS and lack of people that Vee has in his area.

Living in the centre of a big town does have it disadvantages. If I would drive like Vee on the public road, I would be arrested for endangerement of others within the hour      
(Or end up in hospital after my first fall on solid concrete at 35 km/h).

 The first 7 Xtreme pieces will arrive to my Dealer in the beginning of next week

Next 40 pieces will be here after 40 days....

Hope to get my 2 pieces next week 

Can't resist to wait 40 days more....

@Zugu: are there any videos & Photos of the new units? All I can find is old and at least a few months old.

​in the previous page I posted a picture of the 2 last demo units I tried last May 9th in Naples Italy.

Exactly. Products made of "normal" use benefit from a very much extreme sports, precisely because the devices are proven in extreme conditions.

But I understand that there are people who want to drive safely in the street max 15kmh. So do I.

But there are always people who want to make transport more than it is as safe to use.

Is it safe to ski? Is motocross safe?
Is the rally in safe? The list could go on forever..

But all of these have in common very much. Ordinary people benefit from these species, even if they do not use themselves on the street exactly the same tools.
Different tools for different purposes. It is clear. I do not want that all the unicycle's run 60-80kmh. But there should also be available for such. Although I do not want them on the street.

No one wants that the F1 car is being driven in the street
And no one will want to run Motocross guards wearing the dairy trade.

The matter need to look more widely. And in the long run.
Certainly, there will be a unicycle, and more with a top speed of 100kmh and more. But how soon, it depends on the manufacturers. But be sure to always find buyers for them.
If not, then the world is no longer anyone ever fondest other than philately.

Just now people are not yet woken up to what all the possibilities unicycle can offer. But it will not take long.

Zugu, would you be able to weight your SoloWheel Xtreme? The 'official' Solowheel website gives the product weight as 12kg, but according to a source who owns one it's more like 13.5kg. Can you clarify this point please?

​No .. not own mine yet !!

Last 9th May we weight the 2 Demo units and they were 12 Kg and the surprise was that even if Xtreme is almost 800g heavier than Classic, it's better balanced and seems more light than the Classic. ...

This is the Italian Dealer in a short ride:

 

[Sam Clegg]

The extreme is real!    Can't wait to get mine.   Will contact inventist today to make sure that people like me who have pre-ordered get theirs ASAP.   I reall hope the firmware is 'stiffer' than the original solowheel.    Any news on the solowheel bluetooth app that is supported to come with the extreme?

[zugu]

Not yet. . Anyway Mr. Chen told us that will be an app almost complete ! Plus, as rumors, told us that will have the function to set the speed limit point .

I asked him to implement either the ability to set and to choice the 2 modes Hard or Soft inside the app :-)

[Jason McNeil]

It will be interesting to hear how it compares to one of the other 18" Wheels. I'm very skeptical of the claim that the power output is 1,800W. At the battery level, the maths don't add up, even using the standard Chinese formula of peak-out. According to the data on the Xteme's product page, the Wheel uses Sony US18650V3 cells, which is well documented to produce sustained output of 10A. http://www.dampfakkus.de/akkutest.php?id=106

We know the capacity of the pack is 155Wh & the capacity of the cell is about 8.25Wh, depending on the way SoloWheel are calculating capacity, they're using between 16-20 cells. So 3.7v x 10A x 20 cells = 740W sustained, a far way off from the advertised 1,800W!  As an aside, vendors like Airwheel/IPS frequently use a standard power formula of 43.75W power per cell.

VC3 battery

Solowheel uses the highest-quality battery available, providing reliable high performance and safety. The VC3 battery is non-flammable and non-explosive. Each battery cell has independent dual protection.

The top speed is limited mainly by the air drag(?resistance?)​. So with 1000W of motor power you could reach a theoretical top speed of about 54 km/h (without taking the losses by friction/"rubber workout"/traction/etc into account). And the wheel itself needs some margin to the topspeed for balancing.

To reach a top speed of 100km/h you would need a motor power of about 6500W. This would mean 117A of a 55,5V battery back...

(P=F*v, F=1/2*cw*roh*A*v² -> v=(P/(2*cw*roh*A))^(1/3) with cw=0.9, A=0,5m², rho=1,29 kg/m³ <-> I hope this is about right )

Edit: I'm not really sure, if the equations with P=F*v makes any sense or if one has to use the torque and the angular speed. But since i do not have the torque from the motor i just hope, that the result is the same...
