It's been done a long time ago with just higher gearing ratios. A bike designed for a velodrome has extremely high gearing ratios, and it's not uncommon for racers to get over 50MPH with people even being killed during events. The high gearing ratio is very hard on your knees. I used to bike a lot when I was younger, when I got into my mid 20's, biking in the lowest gear all the time started to effect my knees. Trust me, you don't want to ride something like this once you start to loose your cartilage.

Подходит для ровных дорог, а вот уклоны тяжело будет преодолевать на таком. Потому и придумали системы переключения передач типа Shimano. Если нужно выжать весь скоростной потенциал, достаточно просто поставить 7- или 8-ступечатую кассету с минимальным числом зубьев на звезде 11, а ведущую звезду поставить 52. Тогда на 1 оборот педали будет приходится 4.72 оборота колеса, что вполне оптимально, в зависимости от диаметра обода.
Да не будет это работать и на ровных дорогах. Проблема разгона велосипеда далеко не в передаточных соотношениях. Ничто не помешало бы установить переднюю звезду хоть на 100 зубьев и разгоняться до сотки. Куда вы денете сопротивление воздуха и трение качения? А именно они и тормозят велосипедиста, причем их сопротивление растет тем быстрее, чем больше скорость. Так, например, при скорости 20-25 км/ч сопротивление воздуха не особо ощущается, едешь расслабленно. 30-35км/ уже тяжелее, 40 и выше- приходится "продавливать" воздух, это понятно уже по трепыхающейся одежде и жуткому ветру в ушах. Воздух на больших скоростях уже похож на жидкость в некоторой степени.
It would be interesting to do some calculations to see what would fail first on a stiff hill: 1) rider's legs, 2) gear teeth, 3) chain, 4) gear connection point, 5) pedal crankshaft, 6) pedals, 7) something else. I would also be interested to see a top speed without the modification using GPS and a top speed after.
He should refine it. Maybe add intermediate gears or a tiny electric motor in the wheel to ease the torque. A lighter bike would help too. Cool idea anyway ☺

It's been about 7yrs since I've worked around machinery as in machine repair department. At first didn't see the difference was then started to think once again. Thanks to you, no blaspheme intended, I see the light once more! Very ingenious!
If you knew anything about practical science and applied physics you would realize that the middle sprocket makes absolutely no difference to the final ratio between the front and rear sprockets.
@@MsMara287 I'm your first like. I'm just a simple machine repair guy, nothing more. Plain and simple, like a Amish or Minnonites simple.... Thanks for that invite of applied science, I love science, history and mathematic stuff.....
@@MsMara287 Actually, it does something: It adds friction, making this "very ingenious" design less efficient than having the same gear ratio between merely two gears. But yeah, anyone with a basic understanding of "applied physics" as you called it ("Technical Mechanics" would be the appopriate course in engineering studies) would see within 2 seconds, what is really going on here
The principle is good, but there are lots of problems here too. Firstly the rear freewheel he removes is probably a 16 tooth. It would be far easier to replace the rear wheel with a freehub design which would allow an 11 tooth sprocket. Similarly it's also easier to increase the chainring size at the same time. Secondly the stresses going through the chainstay will be enormous....far more than the tubing was designed for. However I like the concept though. To have a secondary gear would allow for incredibly high gear ratios (or low ratio too). Interesting for record attempts etc, or recumbent bike that achieve high cruising speeds.
You have to be strong as a beast to power that top speed. Higher gears have higher top end but it divides your torque to overcome the tendency to remain still.
У многоскоростного на высокой передаче крутить трудно и чувствуется сопротивление ветра. На более повышенной просто сил не хватит. Хуею с таких видео ради проммотров
Dos detalles. 1.-. El primer plato es de 48 dientes , el segundo de 39 y vos piñones de 16. Según el ensamblado por cada vuelta de pedal, se obtiene 7.3 vueltas de rueda. Eso se puede superar con un plato de 60 dientes para bicicleta plegable junto con un piñon de 8 dientes para BMX.

In essence you've constructed a heavier, odd-looking overdrive gearing, very much like what internal bike hubs have. Of course the overdrive ratio is 2.43 : 1 , unlike an internal 3 gear hub which gives you 1,33 : 1 on the "normal" chainring/sprocket ratio

This piece of mechanical engineering will ensure the rider doesn't skip leg day. Try going uphill with this. The rider is going to need to exert a hell of a lot of torque.
Great for increasing the speed your wheel turns when it's not pushing your bike (and you) along the road.... no free lunch, increased ratio equals increased torque to turn it.
I like it. You might be able to add a stack of shifting gears atop the orange gear that you could use to shift to a better ratio on hills. I don't see anywhere else conventional bike parts would work. (Edit nevermind look at the clearance, I think this one stays 1 speed)
You could just use a shifter with some sensible ratios. 3 gears in the rear is enough to drive up a hill and drive faster on flat ground than you will ever want to on a bike like that.
There is a Big problem, it's impossible to get more power, the power is constant so it doesn't matter how you mount the chains. According to the laws of physics, you can never get more power out than you produce. I was around 12 years old when I learned this in school. Another thing is What you gain in power you lose in length. This applies to blocks and hoists, where you can lift a car yourself, but then you need a very long rope 😊
As someone who's built dozens of e-bikes every hub motor e-bike could use this. Once a decent size motor is up to speed there's no chance you can input any power by pedaling with a normal setup.
@@Aslan-ed1gz it's not force it's speed Mr. Simple mechanics. And either way I'm telling you the average person can't apply it once a motor is fully engaged. What did you miss? How can I clarify this to you so you don't feel so ignorant? I'll break it down real simple. The average person can probably ride a bike around 20 mph at best. Once you exceed that speed limit with the motor you're no longer inputting human power. If you can't comprehend it after that I probably won't even give it another shot.
I'd have to try it to believe it.... The more you increase the speed the more torque you lose. There are reasons why bicycles are made the way they are.
That's great if you turn the pedals by hand and the wheel not in contact with the ground. But once you place the bike on the ground and try to pedal it, it would be very heavy to push. You might not be able to pedal it on even small inclines. Great for flat roads or the track, though.
most of the time I see this being done, the power source is changed from pedals to an old Briggs 5HP motor. Resulting in a bicycle that goes far faster than it's brakes are designed for.
I started life as a roof tiler. Every day humping 70 to 100 pounds of tiles up a ladder and across the roof. My legs muscles were huge after 5 years of this. I was clocked with a friend in his car at 55 mph .
Eso ya lo planee tiempo atrás. Pero tiene desventajas , es que requiere el triple de fuerza de lo que usamos con normalidad , las piernas se cansan rápido ,y no es conveniente para uso constante
What is your speed in 20 degrees uphill ? Could you get the same speed on level ground as shown in your video if you are going uphill? please answer, thank you......IF YOU WILL NOT ANSWER THE QUESTION THAT INDICATES THE ANSWER IS NO......i could imagine MAYBE you cannot even move.....PLEASE TELL ME I AM WRONG !......you are an inventor you supposed to know that !
You could increase the efficiency of this entire design by getting an even larger gear at the front and leaving out the second gear, while maintaining the same effective gear ratio
hope that there will be a part 2.. for you to continue working on the modyfi and additional gear..ofcoz for the hilly and uphill road.. . you are the one who works on it..I bet you can do it sir..👍🙂
The next part will be about modifying the legs, so they can manage to provide the torque through such a high ratio. Anyone who's ridden a multi-gear bike understands that.
Lo pense antes como un proyecto no sabia que alguien más lo tenia en mente me gusta ya que al llegar a una velocidad alta y ir relativamente a pocas vueltas la podes mantener durante un periodo mas largo
pues en realidad te cansas mucho mas cuando pedaleas mas lento, lo idoneo es tener una cadencia alta, con platos grandes y piñones chicos es poisble ir muy rapido y descansado pero a muy altas pedaleadas
La energía no se crea ni se destruye, solo se transforma, a mayor velocidad se requiere más desgaste de energía, sería bueno que lo pruebe en pendiente
speed is inversely proportional to torque so increasing amount of speed at the wheel you will generate lesser torque at the end in short, you need a very musculine powerful leg to drive it in a long road
Notice how we don't see any footage of him going from complete standstill to driving. Then you would see the major flaw of this "single speed, high speed" design: You sacrifice torque. The torque you need to even get going. You will need a lot of force to get moving. And don't even try going uphill with this configuration.
И попробуй в небольшой подъём закатить на таком велосипеде! Обороты огромные на колесе, а усилие на педали ещё больше надо прилагать! На таком только по ровным дорожкам, без подъёмов! Изучай физику, её на нашей планете, пока ещё ни кто не отменял! 😊
“Praise be Allah, Who created the heavens and the earth, and made the Darkness and the Light. Yet those who reject Faith hold (others) as equal, with their Guardian-Lord.” (The Cattle (Al-Anàam),1)
So just like what alot of bikes has gears except this one you can't change the gear. But I understand why you would want it but inclines and dirt is gonna be tough. It will be a lot harder to peddel but in return if you have the energy and the strength you can get some good speed with it. But really only recommend for flat roads. I used to bike ride 80miles a day for over a year. I haven't done that in a few years tho. But if you bike ride enough you will get the strength to keep going. I rode a 29" mountain bike up to 40mph for miles straight. So if you like it and want to go hella fast without the use of a engine or motor. Practice and push yourself
There is a fundamental misunderstanding here: the limiting factor for bicycles is not the gear ratio, it is wind resistance. This video is just showing off welding skills.
What a Great idea for future in all vehicles

@@joseluissolanohuayascachi1811 si, queda tan pesada que no podrás subir nada, te costará hasta arrancar en un lugar parejo, si es para jugar puede ser, pero no tiene utilidad en la realidad, además de que se puede lograr lo mismo en una bici con cambios
@@Lucho-o1f Dale genio, si sabias que existe algo llamado ''entrenamiento'' con el puedes aumentar tus capacidades y lograr mover ese cambio ''tan pesado'' facilmente, no hay que ser un genio para eso, si te sale muy pesado y dificil subir cuestas, solo hazlo muchas veces hasta que obtengas la fuerza necesaria y luego puedas hacerlo como si nada. Que llorones que son carajo.
Un progetto veramente geniale!complimenti !volevo solamente chiederti se nella partenza è dura scatta come una normale bicicletta.
Clever , would be great with a tail wind or downhill :) , a bit hard on the old knees though , if you could make the pedal crank arms variable length while on the go to suit the extra torque required , that might be interesting to try .
Projeto incrível, adoraria experimentar. Tem que ter muita perna pra explorar o máximo desse sistema. Deve ser incrível passar de 40km/h e ainda ter relação pra ir muito mais além. Parabéns.
Como curiosidade, vale. Se você mora em lugar plano, e se tem perna pra embalar, pode até ter algum uso (mas haja perna). Agora, se pegar vento contra, subida ou se tiver muito semáforo no caminho... 🤣
@@alessandropinto5204 kkkkkkkkk verdade, mas treino é treino, né? kkkkkkk simbora pedalar
@@jeffersonallan4903 olha, depois de muitos anos de encarar subidas brutas, meus joelhos já não querem mais saber disso não. A métrica agora não é watts, é sorrisos por km 😁
?Y cuantas veces se incrementan las probabilidades de matarte. ?
53/39 na frente e um cassete 11/25ou mais ,faz isso usava essa relação em bike com aro 26 com rodas leves e pneu 1.0 ainda vou repetir esse projeto novamente recomendo pois já tive
Yes, speed will be high but it's efficiency willnot increased by this because more power required for this system
This piece of mechanical engineering will ensure the rider doesn't skip leg day. Try going uphill with this. The rider is going to need to exert a hell of a lot of torque.
Excellent ! Thank you for showing us and sharing a very smart video 👍
Boka choda video ea you have to read Physics man 😅😅😅😅
I think the pedals are very heavy .It must be very difficult to start the bike..
Great for increasing the speed your wheel turns when it's not pushing your bike (and you) along the road.... no free lunch, increased ratio equals increased torque to turn it.
Well I think if this mechanism is combined with cassette gear system, will work wonderfully.
I like it.
You might be able to add a stack of shifting gears atop the orange gear that you could use to shift to a better ratio on hills. I don't see anywhere else conventional bike parts would work. (Edit nevermind look at the clearance, I think this one stays 1 speed)
You could just use a shifter with some sensible ratios. 3 gears in the rear is enough to drive up a hill and drive faster on flat ground than you will ever want to on a bike like that.
There is a Big problem, it's impossible to get more power, the power is constant so it doesn't matter how you mount the chains.
According to the laws of physics, you can never get more power out than you produce.
I was around 12 years old when I learned this in school.
Another thing is
What you gain in power you lose in length. This applies to blocks and hoists, where you can lift a car yourself, but then you need a very long rope 😊
I never could get how block n hoists work, hearing & levers yes but block (tackles)? , don't quite get em.
As someone who's built dozens of e-bikes every hub motor e-bike could use this. Once a decent size motor is up to speed there's no chance you can input any power by pedaling with a normal setup.
Yes but you need to add more force to the pedal.
Simple mechanics
@@Aslan-ed1gz it's not force it's speed Mr. Simple mechanics. And either way I'm telling you the average person can't apply it once a motor is fully engaged. What did you miss? How can I clarify this to you so you don't feel so ignorant?
I'll break it down real simple. The average person can probably ride a bike around 20 mph at best. Once you exceed that speed limit with the motor you're no longer inputting human power. If you can't comprehend it after that I probably won't even give it another shot.
Гениально! Теперь любой желающий сможет стать чемпионом мира по велоспорту! )))))))))))))))))))

Metode Ide yang bagus tapi harus lebih dikembangkan untuk hasil yang cemerlang
Depois, favor coloquem o tradutor: Como foi o teste na subida acentuada de uma rua? Parece que esta solução é viável em ruas planas.
É viável em qualquer lugar cara, é uma forma de ficar leve, é tipo polia ou alavanca
Isso é física na prática! 👏👏👏😉👍
O foda é subida né véi mmkkk
I'd have to try it to believe it.... The more you increase the speed the more torque you lose. There are reasons why bicycles are made the way they are.
Maravilhoso projeto .Parabéns.
That's great if you turn the pedals by hand and the wheel not in contact with the ground.
But once you place the bike on the ground and try to pedal it, it would be very heavy to push.
You might not be able to pedal it on even small inclines. Great for flat roads or the track, though.
most of the time I see this being done, the power source is changed from pedals to an old Briggs 5HP motor. Resulting in a bicycle that goes far faster than it's brakes are designed for.
we could add hamsters to help pedal up slopes
What a great existing Idea, you just reduce the size of the toothed wheel on the tire, and increase the size on the big toothed wheel...
I started life as a roof tiler. Every day humping 70 to 100 pounds of tiles up a ladder and across the roof. My legs muscles were huge after 5 years of this. I was clocked with a friend in his car at 55 mph .
What
Wow, you can escape from any wild animal except cheetah 🐆
Está dé lujo el invento amigo gracias por el vídeo ya tienes un suscriptor más saludos desde Cúcuta Colombia
This is exactly how bikes with gears work except it's the last gear on this video
Gostei parabéns pela produção do vídeo 👏🏼 👏🏾👏🏾👏🏾👏🏾👍🏽
Eso ya lo planee tiempo atrás. Pero tiene desventajas , es que requiere el triple de fuerza de lo que usamos con normalidad , las piernas se cansan rápido ,y no es conveniente para uso constante
👏👏👏👋 👍👍
Nothing says sketchy like welding over a painted surface. 😂😂😂
What is your speed in 20 degrees uphill ? Could you get the same speed on level ground as shown in your video if you are going uphill? please answer, thank you......IF YOU WILL NOT ANSWER THE QUESTION THAT INDICATES THE ANSWER IS NO......i could imagine MAYBE you cannot even move.....PLEASE TELL ME I AM WRONG !......you are an inventor you supposed to know that !
Ну конечно. Очень жёсткая и надёжная конструкция
I like how he chose a a busy road as his test ground.
and drove in reverse.
Excelente trabalho e idéia.👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
You could increase the efficiency of this entire design by getting an even larger gear at the front
and leaving out the second gear, while maintaining the same effective gear ratio
hope that there will be a part 2.. for you to continue working on the modyfi and additional gear..ofcoz for the hilly and uphill road.. . you are the one who works on it..I bet you can do it sir..👍🙂
The next part will be about modifying the legs, so they can manage to provide the torque through such a high ratio. Anyone who's ridden a multi-gear bike understands that.
@@James_Knott like adding the second legs for the middle primary ..then just change leg into high ratio ...
@@ZeyZard Or just invest in a derailleur gear shift. It does what this design does, but much better in any way and it also does more
Представьте нагрузку на ноги когда на горку едим 😂
Excelente vídeo. Estou tentando fazer o mesmo, mas usando o sistema de polias, para distribuição de força.
Posta aí seu projeto
No momento eu não posso, mas assim que tiver pronto, vou divulgar.
It's only good if we add hub motor in this . After that , we could achieve 40kmph + sprint on road
Gran invento, pero requiere también un aumento exponencial de la energía para poder mover la bici más la persona
De bajada funciona bien. De subida no. Además, las bicicletas de hoy en día ya traen hasta 24 cambios. No es necesario hacer esto.
Parabéns!!! Ficou ótimo 👏🇧🇷
Eu ser Brazil
And that's why gears are for.
Lo pense antes como un proyecto no sabia que alguien más lo tenia en mente me gusta ya que al llegar a una velocidad alta y ir relativamente a pocas vueltas la podes mantener durante un periodo mas largo
pues en realidad te cansas mucho mas cuando pedaleas mas lento, lo idoneo es tener una cadencia alta, con platos grandes y piñones chicos es poisble ir muy rapido y descansado pero a muy altas pedaleadas
No tiene caso ese invento para eso son los cambios de estrellas es perdida de tiempo esa adaptación Tonta
@@user-gj2wj6hm3j 👏👏👏👏👏👍 😊
probably the best single speed bike ever made.
Dios te a dado gracia te bendigo en el nombre de jesus amén

Bom demais este projeto, parabéns.
This technique should apply in all cycles...
Какой умник это придумал? На этом велосипеде только терминатор сможет ездить, особенно на подъем.
Ini lebih canggih lg dengan satu kali dayung lari nya, kencang banget👍👍👍
La energía no se crea ni se destruye, solo se transforma, a mayor velocidad se requiere más desgaste de energía, sería bueno que lo pruebe en pendiente
That would be a great setup for a time trial bike.
speed is inversely proportional to torque
so increasing amount of speed at the wheel you will generate lesser torque at the end
in short, you need a very musculine powerful leg to drive it in a long road
I knew it was possible. "They called me a mad man".
Notice how we don't see any footage of him going from complete standstill to driving.
Then you would see the major flaw of this "single speed, high speed" design:
You sacrifice torque. The torque you need to even get going.
You will need a lot of force to get moving.
And don't even try going uphill with this configuration.
That's awesome. Riding on the highway going against traffic 😂
И попробуй в небольшой подъём закатить на таком велосипеде! Обороты огромные на колесе, а усилие на педали ещё больше надо прилагать! На таком только по ровным дорожкам, без подъёмов! Изучай физику, её на нашей планете, пока ещё ни кто не отменял! 😊
Engineers: 200 years of bicycle history, what makes you think we havent thought of that? Try that on an inclined road and lets see.
Great great! Now enter a 5 kilometer climb, for us to see if it reaches the top.
The slight slope will grind you to a halt
बहोत बहोत ही खूब अच्छा लगा धन्यवाद जी 👍🙏🇮🇳🌷
“Praise be Allah, Who created the heavens and the earth, and made the Darkness and the Light. Yet those who reject Faith hold (others) as equal, with their Guardian-Lord.” (The Cattle (Al-Anàam),1)
So just like what alot of bikes has gears except this one you can't change the gear. But I understand why you would want it but inclines and dirt is gonna be tough. It will be a lot harder to peddel but in return if you have the energy and the strength you can get some good speed with it. But really only recommend for flat roads. I used to bike ride 80miles a day for over a year. I haven't done that in a few years tho. But if you bike ride enough you will get the strength to keep going. I rode a 29" mountain bike up to 40mph for miles straight. So if you like it and want to go hella fast without the use of a engine or motor. Practice and push yourself
There is a fundamental misunderstanding here: the limiting factor for bicycles is not the gear ratio, it is wind resistance. This video is just showing off welding skills.
