Ho to turn it?
Et ça tourne comment? Avec la force des jedi? Pfff quelle indignité
What printer was used to print this shoe? SLA ?
@@indkartallc9900 It was printed on our Sintratec S2 SLS printer (Selective Laser Sintering) with PA12 Nylon.
Designer: "I never found any killer argument to prevent it from going further"
Literally everyone: you can't steer it.
Ha, exactly. Not without losing a ton of energy and momentum to friction…
Looks like it just flexes the belt sideways.
This was exactly my first thought. You can’t turn.
That was the first thing I noticed looking at this design, is how in the heck does it turn?
And without steering, you won't be able to keep balance, so you'll fall after a few seconds
Lack of steering totally limits this to wide curves on proper paving. It's conceptually beautiful, but very niche. That said, I'd love to try it! ❤️
That was my first observation, how in the heck does this thing turn?
It looks like it'd steer the same as a motorcycle. Those turn just fine.
Countersteering required to stay upright! Also dirt in th belt would destroy it.
What if you have 2 infinity wheels?
YES! Thank you- the person that designed this has never ridden a bike.
Bicycles are super efficient designs that are hard to improve on. There are not many products you can use today that have been refined over 200 years of consumer use. Biking on surfaces where you don't have enough grip for 1 wheel drive is usually not a good idea.
Adding a lot of friction, loss of steering, weight, manufacturing complexity, and cost just to increase grip is probably not going to see commercial success. There have been many attempts at 2WD bikes before, some actually making it to the market, but the problem is there's no acutal need for it.
Oh yeah? Then how do you explain square wheels!??
@@jacksonchan6822 drunk carpenter?
A 2wd bicycle is very easy to do in this day and age. Take a rear wheel drive electric bike, add a front wheel electric rim hub, get a big ole battery and watch a how-to video on the You Tubes to figure out how to wire it all up. About 1500 for a decent drive train and 800 to a 1,000 for a good battery... And as far as having a need for it would depend on the terrain and environment you are in.
@@jacksonchan6822 Canadians. That's how. LoL
@@kajunklown Exactly. We can already upgrade a basic bicycle to 2WD AND get the added benefit of electric assist using off-the-shelf parts.
I think it might technically work, but the friction will likely be too much to be a practical design. Looks cool.
Excited to run on a single tire until I get a puncture.
Would love to see this come to fruition. I don't really care about the efficiency issues or the flex steering, or the apparent need for some kind of differential 🤷🏿♂️...Just Do It!
The basic problem of this "all wheel drive" bicycle is the "all wheel drive".
When cornering a normal bicycle's front wheel spins more than the rear wheel because of its larger turning radius.
If you could steer this bike then how would the front wheel turn more than the rear wheel? The "all wheel drive" wouldn't allow it.
That's...actually really smart
Not without losing a lot of energy on friction and rubber deformation.
The guy who designed this really needs to look at why every fuel driven vehicle for the past 200 years has had a differential :P
Good point, he'll need crab steering to flex it in the middle instead of ahead of center, but that might make balance hard. As is it has no rake angle, but it's not a wheel so maybe it doesn't need it.
Exactly. This is basically a unicycle, stretched out to the shape of a figure eight
What would be turning radius??
How does the infinite tyre handle turning ??
This might work in some dystopia future where we have long tracks of perfectly straight bike lanes and you just get off the bike at your stop and someone else who needs to keep going forward will take it over and so on. Just no turning.
This is absurdly complex for that straight bike lane scenario
I have a design that's far less efficient and far more costly than existing technology.
I've been working on it for years.
to turn:
****LIFT FRONT WHEEL FROM DRIVE SURFACE BY WEIGHT SHIFTING TO THE REAR AND ABRUPT PULLING UP OF HANDLE BARS WHILST LEANING TOWARD YOUR TURN DIRECTION****
Y'ALL MISSED A BASIC SUMTHIN'!
bUt I LoOk cOol
IT'S LIKE A MANUAL ON A SKATEBOARD BRO, EZ
@@longebane easy
You wouldn't be able to steer it effectively at lower speeds, and steering it at higher speeds would be much more difficult. Also, the gyroscopic precession that normal bikes rely on to remain stable during wouldn't happen with that design.
I'm actually blown away by how negative and eager people are in the comments to shut this idea down. Innovation is often met with resistance and criticism. So in that thinking this could be an incredible idea. Lol Even if it's flawed, some times having non practical ideas can inspire the practical ones. I love the design I hope to see it in full size or even print it myself one day. Stay inspred and keep working on this project! No matter the outcome it's inspirational and may drive other ideas that improve our world in many different ways. Cheers!
Thanks for your insightful comment Jonathan!
any dirt will destroy the belt. Now I understand why it's called "city cruiser" -- bcause you guys have clean cities there, ha-ha :)
Yea but the country its from the city's are actually clean unlike us city's im more concerned about turning to make a corner even the animation does not show that
I'll get straight to the point: The Romans would have loved this. And it would be great in Holland too, in particular on their long straight dikes. Really innovative though. Looking forward to version 2.0, with a twisty centre section with some form of differential to allow for riding on non Roman roads...
So what is the benefit over a normal bike?
Super Benefit: if you ever find yourself in a situation where you need to make a sudden stop, a sick flip is pretty much guaranteed
Pretty sure that the wipeout when you eventually throw your mono track off the rim will require a hospital visit for sure.
It's like a tank chain on a bike. Not exactly sure what is revolutionary here, but it looks cool.
So the design is super cool, I won't deny that. Would look great in a Sci-fi movie, but there's too many reasons they won't work in reality.
It could work, either way it would good for science..
@@yashnanda3427 science.. Of what?
@@longebane science of not being able to steer lol
This bike should go to Mars inside the Vulvaspaceship! Great achievements of mankind!
First up, it looks super, super cool and I do want to try riding one... but there are a few immediate issues that I can see. Yes there is the issue of steering that everyone has pointed out, but there is also the issue of bicycle and motorbike wheels moving at different speeds when cornering / turning / going over bumpy surfaces (or jumps). The 1 continuous "wheel" means that you've got a locked system. I can't see a good use case for this... but I still want one to try :)
Thanks for your constructive comment Paul - the concept definitely needs further improvement.
if you look closely between the drive pedals and the front suspension youll see and upper and lower steering pivots. i hove no idea about the intended degree of steering angle. but it appears there is some. Im much more curious about the gyro properties that keep a normal bicycle upright.
Incredibly interesting design! I think the steering “opportunity” could be solved. The question is weight/rider strength and cost.
If you don’t like my comment, don’t bother me with your “yeah but…, yeah but,….” Your criticisms of another’s creative design are an important.
Thank you for the kind words Andrew
Cool design, but when you said I haven't found any killer arguement that would disprove the design. I have one,, how to you turn? Haha
I love Stephen Henrich design. You should check his latest work: The squared wheels, perfect for climbing stairs
What about friction?
Without Bearing how to solve that problem?
When i asked for a light cycle from Tron, I did not expected that !
How does it turn?
A flat tyre would mean taking the entire thing to pieces over a period of weeks.
this requires the "wheel" to be under constantly changing directions of stress and friction, so this would practically be extremely inefficient and not very durable, since stress-hardening will very quickly change the elastic properties of whatever you use for the wheel.
What’s the turning radius 🦴???
it's a cool concept and would be doable IMHO, but there are many downsides.
- a lot of friction
- a lot of bending of the flexible tire which needs energy
- flexible tire needs to be solid, otherwise it won't bend "inwards"
- dirt gets into the mechanism as the rollers touch the driving surface of the wheel
- steering can be hard to archive as it introduces a "side bend" axis to the flexible tire
- tire needs to be flexible in all "bend" axis but should be absolutely resistant to stretching or compression -> need some sort of ball Ingerlinks between the teeth
- energy I applied at the worst possible position on the flexible tire.
Many have already mentioned the issue about the steering. How do you steer in this bike?
Y como giras? Me gusta la idea y el diseño q tiene. Pero como haces para girar hacia los costados en una esq cerrada?
Whats about cornering? Meaning both whelpasses on ground.
As cool as it looks I got to ask. How do you turn with that thing?
Instructions:
-Warning: Only ride on dry pavement.
-Use your toothbrush to clean between each belt "tooth" after each ride.
- If applicable, use provided jockstrap to keep a necessary items out of belt teeth.
-Enjoy.
If I had money I totally support it and also do you know any way I can get my hands on the concept art and research on it and try to make a working to scale prototype somehow
How to turn?
Yes... Thats what I too thought...!
You don't turn. It is only for going in a dead straight line!
How does steering worl
Was ist mit Physik? die Reibung und der Wiederstand aufgrund der der Verengung im Umlauf sollte um einiges höher sein als bei einem ( oder sogar zwei ) Rädern die parallel verbunden sind. Aber vom optischen ein tolles Konzept, zugegeben
Why do designers keep trying to literally reinvent the wheel?
Funny how they all fail too 🤔 Haha!
How do you turn?
Y como se realizan las maniobras con ese diseño????
Круто, я бы на таком прокатнулся.
How do you steer this bike?
how do you turn?
This is an interesting concept bike but far from a peek into the future. Think of the torque would it to push all that forward. How would you stop going down hill at high speeds the singlar gear would blow your knees out 😆. Keep pushing, you'll get there.
You don't need engineering background to know this is a failure. Any kind of spare part is not going to be easy to find.
So that's one continuous tire how do you turn
The faster the wheel moves, the greater the force on concave center -- the single wheel wants to be circular.
How do you steer it?🤔
Seriously? You haven't come across any killer arguments why this concept bicycle will not get past the novelty model you have in your hand. That's so funny. Here's three... Steering friction and cost. That being said it's a wonderful piece of conceptual art.
كيف سيتم الدوران الى اليمين او اليسار دون ان تفقد عزم الحركة المطلوب !؟
It looks super cool, but what can it do that any existing bicycle design doesn't do already, and almost positively better. After all, that's the point of engineering and design, not to make things more complex, but rather the opposite: to make things simpler, more reliable, easier to maintain, easier to manufacture, easier to repair, and lower cost in materials, etc. This design doesn't appear to meet ANY of those criteria.
Again, it looks cool, would be awesome, and I would love to see actually built, just to see it in action alone. It's a piece of art, really.
yeah its a fun design exercise but agree, show me the use case.
"Making the complex simple, that's creativity" Charles Mingus
Interesting concept... What about rain? 🤔
Looks tight though. Like Tron-esque.
Thanks Paul
One issue with that design, how would we steer the bike?
Beautiful design, but I have my doubts. Especially about steering, I'd love to see an actually functional build to prove the concept.
How do you turn. And I don’t mean leaning
How do you change a flat 🤔
Whats the inertia like on an infinity wheel? Circles are awesome for inertia and helps keep the rider upright
Très jolie très bonne conception mais avec un seul et même pneu j'aimerais savoir comment c'est vous pour bloquer seulement le frein avant ou le frein arriere
C'est un projet purement esthétique
Ummm how do you steer it?
No flywheel or gearing system?
Warhammer fans: "The Chaos Bike"
My cousin Ruben has one of those
Turning?
How the heck you turn the thing.
Só queria saber como faz pra virar
Круто!
Might be great... in a straight line. The limited steering could present an issue.
Why have 2 brake leavers on it
That bike was invented by chicanos long time ago !!!! Looks like a Low rider bike to me!!! Con on now!!!
Changing the tire could be cost a lot of time!
Como giras?
What about making turns?
Could you imagine changing the tire?
"I never found any killer argument to prevent it from going further"
👍🏆👍
Muy ingeniosa; sin embargo deberá ser muy complicado girar el manubrio...
Is there free STL file?
unfortunately no, Stephan Henrich has not made the file publicly available.
... But how does it turn?
Howard Moon?
This has to be joke or the designer is doing this just to raise a bit of money or publicity. Next he will be redesigning spoons.
My first thought seeing this was what a shitfest it must be when you happen to drive through some dog shit. It would be everywhere
y como carajo doblo esa cosa? creo q se olvido de eso
Say hello to the bike-tank concept. Looks simple to manufacture and steer... /Sarcasm I imagine this handles as well as a tank too. Looks interesting but not practical.
What principle or concept already in the bike industry is this design improving on? I don't see it.
The bike where you can only go forward.
F*CKING ROASTED 👌
if there is no killer argument against it....
where is the working prototype video to shut up all critics?
I think it's mostly a matter of time & cost - someone would have to fund that project as Stephan says in the video
The epitome of over-engineered
Seeing a lot of comments shooting this thing down, instead of trying to find a solution for the steering issue. Shame on you
Why does anybody here have to "find a solution for the steering issue"? Steering has never been an issue on bikes before. This guy took the working concept of a bicycle and ruined it. Not just the steering either, he ruined practically everything else you can on a bike too: friction, suspension, ease of maintenance, safety (cost probably). This is more art piece than transportation.
Actually no, scratch that. This is artwork, nothing more. You can't even compare it to a real bicycle, it fails so badly on every level.
Oh, and BTW: the guy literally invites criticisms in this 1 min video himself. He said, "I haven't heard any killer arguments that invalidate the concept yet." Everyone here is providing those for him. He may actually be a narcissist who completely tunes out valid criticisms, because it's so hard to believe "nobody told him any killer arguments yet".
怎么转弯?
Did this guy had heard about dry friction ?
I hope it works
Consulta: dobla???
No parece que pueda doblar...
Uh ... hmmm ... how do you turn?
Uh-oh. I fell into a yanko design rabbit hole again.
Problem 1 you cant steer it
Problem 2 for normal bicycle you have larger sprocket at pedal and smaller sprocket at rear. Here one sprocket need to push bike so more effort to drive
I love it every time I see cool startup wannabees who set off to "reinvent the bicycle" only to reveal that they have absolutely no idea how a bicycle works
I hate to change a flat on that thing.
Steering? Perhaps...
