Who said wheels have to be round? 

The triangle wheel is a welcome improvement over the old fashion square wheel. It eliminates one bump.

Imagine taking a nice quiet walk in the park and suddenly hearing what sounds like an infantry of men marching in medieval knight armors only to see this guy with his bicycle.

For anyone curios this shape is called a "shape of constant width". Since when the triangle sticks out more on one side, it sticks out less on the other side so they cancel out. The problem is that this is only true for the entire shape, not a radius from the center, so that's why he had to make those long rollers so the bike is effectively rolling the shapes between the rollers and the ground, thus using the full width, so it doesn't make him bob up and down

Engineering Masterpiece. The fsct that its not a bumpy bike, the rollers cancel out the bumpyness, makes this into an actual genius masterpiece, if not very usable, but something worthy of somebodys bike collection.

A bicycle ride can't get smoother than that. 😂

Alternative title: "This is why wheels are round".

I like how it's not about how he should, but the fact that he's able to.

"What were you smoking when you came up with this idea?" "Yes"

Reinvention of the wheels... just to make it more complicated. Mission accomplished 😂

I hadn't thought about the Reuleaux triangle in years. It's the design used for a "drill bit" to cut a square mortise hole. I remember a Scientific American discussion of it by Martin Gardner in the 1960s. Never thought of an other use for it. Very good!

We spent so long asking if it could be done, we never stopped to ask ourselves if it should be done

a ridiculous amount of effort goes into these builds. don't know how you come up with these ideas. absolutely love it.

It’s also interesting that you could replace with round wheels and have a crazy suspension system above each rack of bearings

I'd be too ashamed to show my face.

I wonder how long it takes to break all the laws of physics and make something that shouldn't be spinning spin?

"Always trying to reinvent the wheel" Him: And I took that personally

Finally a bike that can operate at less than walking speed!

Can you do long narrow rectangles? That would be impressive.

My dude really out here reinventing the wheel

"Who said wheels have to be round?" Just 6,000-plus years of human history, that's all.

Because of how a Reuleaux triangle works the wheels pivot point has to be able to move which ads complexity and friction. This solution also results in the bike having no suspension. A great example of an idea that works in theory but isn’t really practical due to its lack in efficiency.

O cara estuda , pra resolver um problema que antes não tinha. Kkkkk

I can't decide if it's the editing or the finished product that are the best in your videos, but as always, they are both great!

Na prática só serve pra mostrar que a roda redonda é melhor😂

This guy really hates normal bikes. Also how the bearings worked really surprised me. Great job.

I don't think it will last for long however I love the way you made the bicycle self adjust the height. Try to let someone 3d print you rims to fit tubes.

I imagine the people in the place you live just go "what weird bike has he made this time?" When they see you haha, nice job :D

Brap Brap! I guess spinning doritos makes noise in a bike as well.

Pessoas normais: Barato e Simples Engenheiros estranhos: Caro e complicado.

I have studied Industrial Design and now I study Art. I get very nostalgic when I watch your videos. You are doing a great job and it is very inspiring! Keep on building stuff! Im very exited where this channel and you are going and how you develop. Great to see. Greetings from germany!

"Who says wheels have to be round?" - - - The laws of physics. None of this dude's ideas consider rational stability and actual comfort.

I don't think you can expect a comfortable ride, but the ideas and actions are always great!

He gave thumbs up but you can sense that he just wanted to get off it as quickly as possible.

I had questions about how that would provide a smooth ride right until the end. Bravo!

That advertisement, right at the beginning, just PISSES me the H-E- Double Toothpicks off.

What's the purpose of the rollers at the top of each "wheel"?

If wheels were made triangles initially, the circular wheels would have been a revolution😂😂

Bro you should open a bicycle 🚲 showroom and that store name should be (The Unique cycle store) 😅

Is this a stupidity contest? We have a winner 🏆

The sound of the rotary engine keeps coming to mind😂😂😂

Love the sound effect, really convinces a skeptic that this could replace the round wheel.

タイヤの回転がちゃんと成立してるのがすごい

Wonder if there is a way to smooth out the ride or at least make the bumps more "wavy" like parabolas.

You should have explanied the math besides that wheel design that is a one special where the distance between up and down of the wheel or any diameter is always the same that's why you can use them in a bike with no problem in your seat

"Wheels must be round? Who decided that?" Well, Logic itself: less mecanical parts means fewer chances of failures, less engineering and lower parts' price. Add the fact that the suspension must be stiff as f cause you don't have air in your tyres, nor even a dedicated suspension. Speaking of tyres, you must wear them off quickly since they are in contact with the ground AND the rollers, causing useless friction, hence tiring you down in no time. Yet, this machine is cool to see as an application of mechanical principles.

Me: Mom can you buy me a bike Mom: We can make our bike at home Bike:

Für alle, die neugierig sind, wird diese Form als "Form mit konstanter Breite" bezeichnet. Denn wenn das Dreieck auf einer Seite mehr herausragt, steht es auf der anderen Seite weniger heraus, so dass sie sich aufheben. Das Problem ist, dass dies nur für die gesamte Form gilt, nicht für einen Radius von der Mitte, deshalb musste er diese langen Rollen herstellen, damit das Fahrrad die Formen effektiv zwischen den Rollen und dem Boden rollt und so die volle Breite nutzt, damit er nicht auf und ab wippt

That's an excellent build dude 👍, but also really funny to see riding along 😁. It almost looks like it's busted 😂. Love it! 😎

Only a circular wheel will give you a more smoother and faster ride, not any other wheel shapes!!! See closely, there's a jerk up and down, when he rides the bicycle!!!👍👍👍👍👍👍👍👍.

I'd like to see if this can be ridden around corners at speed.

Riding a bike with the triangular wheels sounds like eating crisps

The invention of the wheel is considered one of the most important achievements in human history. Wheels have revolutionized transportation and made it easier to move heavy loads. However, what if the wheel was not round? What if it was a different shape, like a triangle? Triangle wheels may seem like an odd idea, but they have been proposed as a potential solution to some transportation challenges. 1. What are triangle wheels? Triangle wheels are wheels that are shaped like a triangle instead of a circle. They have three sides and three points, which make them look like a triangle. The idea behind triangle wheels is that they could potentially provide better traction and stability than traditional circular wheels. 2. How do triangle wheels work? Triangle wheels work by using their three sides to provide more contact with the ground than a traditional circular wheel. The increased contact area could potentially provide better traction and stability in certain situations, such as on uneven terrain or in slippery conditions. 3. What are the benefits of triangle wheels? One potential benefit of triangle wheels is that they could provide better traction and stability in certain situations. For example, they may be useful for off-road vehicles that need to navigate rough terrain. Triangle wheels could also potentially provide better braking and acceleration performance. 4. What are the drawbacks of triangle wheels? One of the main drawbacks of triangle wheels is that they may not be as efficient as circular wheels. The triangular shape may cause more friction and resistance, which could result in increased energy consumption. Additionally, trianglewheels may be more difficult to manufacture and maintain compared to traditional circular wheels. 5. Are triangle wheels a new idea? Triangle wheels are not a new idea, and variations of triangular-shaped wheels have been proposed and experimented with in the past. For example, the Triskate is a type of rollerblade that uses three oval-shaped wheels instead of traditional circular wheels. 6. What are some potential applications for triangle wheels? Triangle wheels may have potential applications in a variety of fields, including off-road vehicles, military vehicles, and robotics. They may also be useful in situations where traditional circular wheels cannot provide sufficient traction or stability, such as in icy or slippery conditions. 7. What are some challenges to implementing triangle wheels? One of the main challenges to implementing triangle wheels is developing a manufacturing process that is efficient and cost-effective. Additionally, testing and evaluating the performance of triangle wheels may require specialized equipment and facilities. 8. Are there any examples of triangle wheels being used in practice? While triangle wheels are not currently widely used in practice, there have been some examples of triangular-shaped wheels being used in specific applications. For example, the Ripsaw EV2, a high-performance military vehicle, uses triangular-shaped track wheels for improved off-road performance. 9. What are some potential future developments for triangle wheels? As technology continues to advance, it is possible that triangle wheels could become more practical and cost-effective to manufacture. Additionally, further research and development may lead to improved designs that offer even better performanceand efficiency. 10. Conclusion: Triangle wheels may seem like an odd idea, but they have the potential to provide better traction and stability in certain situations. While they are not currently widely used in practice, there have been some examples of triangular-shaped wheels being used in specific applications. However, implementing triangle wheels poses several challenges, such as developing a manufacturing process that is efficient and cost-effective and testing and evaluating their performance. As technology continues to advance, it is possible that triangle wheels could become more practical and cost-effective to manufacture, and further research and development may lead to improved designs that offer even better performance and efficiency. Overall, while the idea of triangle wheels may seem unconventional, it is an interesting concept that could have potential applications in various fields.

I want one! I'm thinking a bit of padding under the tires would help with comfort. Maybe make the wheels a bit smaller and use an actual inner tube. After all, the tube is flexible so it can be shaped into a Reuleaux triangle. Maybe. It might put too much stress on the tube, so maybe use those non-inflating inner tubes instead. Maybe try "Reuleaux pentagons", then those roller assemblies don't have to be as long.

Bicycle be like : kaha fas gyi Mai 😅

The ad is at peak views. No greater sign of bots exists than people wanting to see the ad more than the content.

Still waiting for him making a tank-speed wheels bike. Not the square one, or maybe square but with faster velocity 😎😤👍

Dude, we wouldn't have a hungry child in the world if you spent time trying to figure that problem out instead of trying to reinvent the wheel

Smooth ride, just wondering how long the suspension bearings can hold.

The perfect way to make what is actually very easy difficult.

This video is so well done. I mean the editing is as inventive as the bike.

Everybody's so creative. Have you ever wanted a bicycle that sounds like a shopping cart with a broken wheel, well now you can. See how you think it might ride smooth but it doesn't. Don't worry its supposed to be that way its just differnetly different.

I can’t get enough of this channel. Look forward to each and every video.

Thank you for leaving in the sound

Que bom que esses engenheiros tem tempo sobrando!!! Poderiam ter uma idéia genial pra salvar vidas, ajudar ao próximo e por aí vai...

Answer for the question: I said it before I watched this video and realized that there is an alternative for round wheels; the reuleaux triangle wheels which also gives a smooth movement. But my question is Why these wheels aren't introduced to be used in public officially?🤔🤔 Hmm..... Whatever.

5:55 wasted life time

The world has been waiting for a 100 pound bike with square wheels, thanks!

this guy is cool, feel pity for people who don't like his work where they're not the one who feeding him...good or not, as long there's an idea is good enough...

How to make a bike sound like a locomotive from the 1800's 101

E quando penso que o ser humano não pode piorar mais as coisas... Ele consegue!! Kkkk

This is like a fashion show. No one uses those clothes in day to day life.

mom: editor dad: mechanical engineer son: the Q

When I was a kid, I read a science fiction short story in which triangular tires were used to skirt an alien culture's religious prohibitions against using standard wheels, because circles were considered a sacred shape. After some creative Googling (it's hard when you remember the premise but not the author or title), I determined it was 'The Three-Cornered Wheel' by Poul Anderson. It's part of his Technic History series. You're welcome. 😉

Amazing build my friend! Such exquisite building. My jaw dropped the whole video :0

You just proved beyond a reasonable doubt that wheels DO NEED TO BE ROUND! Try cycling any distance with that and you might believe it too!

Sir you are a legend ❤

Que agonia, parece que a qualquer momento ela vai desmontar kkkkkk😂

These Engineers have to be interned, they are crazy 😂😂😂

You're so creative 😍

Honestly, good experiment and creation, But if that is put into a market at some point it will be a dumb waste, why buy a busted one over something normal. (Realistically said, no hate to the bike and the creator itself)

WHY ??? I repeat WHY ??? Some people have waaaayyyy too much free time !

That rattle sound kills the entire experience for me. It sounds like a 5 year old practicing the damn shakers for his first Christmas concert!!!

My back. My back says wheels can’t be round when it tells my brain how much it hurts because the wheels were not round 😁

People on the verge of rediscovering the circular wheel. Keep going. This is how cave man came up with a optimized shape for wheels.

It's a very smart Invention ! In this way, you can achieve continuous momentum.

Maybe a spring loaded chain tensioner could help prevent the chain jumping

There is a reason wheels are round. Mythbusters made square rims for a truck. Destroyed the truck. You have doubled the weight of the bike, added rolling friction in so many ways, and no way this can take any kind of a curve without crashing. There are so many failure prone pivot joints. I know it is just an idea but I don't think it will catch on. Engineer for simplicity whenever possible. I'm guessing RU-vid pays pretty well.

*Always making wheel invention more complicated😊*

How to make something more difficult to manufacture. Not something I would buy, but I admit it's an eye catcher.

Watch in slow motion the position of the front wheel is different from the rear wheel, thanks to the flexible switches and the upper mats, that is, the front wheel at a certain moment turns faster and so one wheel compensates the other! 🇧🇷

Reuleaux's triangle! The basement of rotary engine of Mazda's automobile.

Oscar for the film! It perfectly shows your excellent skills in design, mechanics, but ... lost time (unless...you wanted to attract someone's attention). Uneffective, danger to move over any slippery surface - just imagine yourself turning with not constant contact to the ground - the horror. Of course I understand it was your plan, as the main goal was to make something good for commercials, not for everyday use. OK, you may streamline the design a bit - making corners of the triang-wheels a bit rounded, smoothed.

Yea... How about we make a bike that uses more energy than it gives. This guy: hold my beer

I think you should find some way of putting air into these tires, that'll make for a smoother ride.

There was a reason why wheels were made circular.

It would be best to collect all your crazy bikes and make ride of 20-30 people. It would be insane to see them altogether.

My 12 yr old granddaughter told me not long ago that all wheels are round. I will forward this video to her.

I had to look a second time before I saw how this works. The bike suspension is NOT suspending the bike. The racks of rollers are suspending the bike on top of the wheels.

An experiment in lunacy. Looks bloody hard work to me. Maybe that's why he's going so slow. Not to mention the extra stresses on the frame, the wheels & the bearings. Madness. Very noisy! Remember - noise means lost energy!
