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.

@@vanshbhavsar9024 You probably don't bike a lot, but if you have a bike, try to bike in the top gear at all times. This WILL grind your knees. What is demoed here is 10 times worse. I used to bike a lot, and I was always in top gear unless I was climbing. This is an interesting example of gearing ratios, but there is a reason we don't have them at this level.

Scientifically, no matter how much u increase speed by gears, it will take the same amount of effort from you to reach point B from point A. That's because the more gears you increase the more difficult it would be for you to pedal and you will reach point B faster at the cost of getting exhausted sooner. On the other hand if u use lesser gear you will reach point B slower but this time u'll get exhausted slower as well. In both cases your exhaustion after reaching point B will be the *SAME* , that's my point...... Still if u have doubts here's some physics for you: Let's consider the total force that you have applied on the pedal throughout the whole path be "F". Now let "T" be the total time taken to reach point "B" from point "A". Suppose you are moving with a constant speed. Also let us suppose that your gear combo is able to make you go *"n"* times faster/slower. But time, now *"T"* is *inversely proportional* to "n" but "n" is directly proportional to the Force, *"F"* you are applying on the pedal, because you are *increasing speed at the cost of losing mechanical leverage of the pedal.* So, *n varies F ---(1)* & *n varies 1/T ---(2)* From (1) & (2) we get, n varies F/T Or, n = k × (F/T) Or, *k = (n × T)/F ---(3)* [Where, "k" is proportionality constant] Case 1: When your gear combo increases your speed. Therefore "n" increases to "n1", "T" decreases to "T1" so, *k = (n1 × T1)/F1 ---(4)* [Let us assume the force be F1] Case 2: When your gear combo decreases your speed. Therefore "n" decreases to "n2", "T" increases to "T2" so, *k = (n2 × T2)/F2 ---(5)* [Let us assume the force be F2] From (4) & (5) we get: *(n2 × T2)/F2 = (n1 × T1)/F1* But *n2 × T2* = *n1 × T1* = *a constant* _[since, from (2),_ _n varies 1/T_ _or, n = constant/T_ _so, _*_n × T = constant_*_ ]_ So, *constant/F2* = *constant/F1* Or, *F1 = F2* *↑ This proves that the total force that you applied on the pedal throughout the journey from point A to point B is same no matter what your gear combo is.* Additional fact (for those who still gonna point out biology stuff hoping that it can prove me wrong): it's true that our legs are designed in such a way that it cannot change the amount of effort taken linearly with change in rpm. But still I am saying that cycle, friction with the road, gears, and all other factors will make our leg muscles lose same amount of chemical energy at the end of the journey. Because at the end the work done by you is the same as the distance is same. The only thing you can increase or decrease is the force u apply on the pedal which can make u go faster by decreasing the time it will take or vice versa. Your cycle will take away same amount of energy from you after u reach point B. But well to make your point legit we have to consider the energy radiating out from our muscles in form of *heat* and getting wasted, to counter that heat our body produces "sweat" to keep ourselves from overheating, now yes that is something that I haven't considered because I was talking about cycling in daily life, not Olympic cycling races where they cycle for a long time at extreme speeds. So what I'm trynna say, is that to reach a destination with the help of anything be it a vehicle, be it your own body, or be it an another living being carrying you, the work done to do the displacement is always constant no matter how fast or slow u reach that point. The result never feels the same because we waste a lot of energy due to friction, and all other stuffs. Even in a car, the energy needed for the work to be done is always a constant, if the result is not a constant then that means energy got wasted in form of heat, sound or in some cases light. So at lower gears a lot of energy gets wasted in form of heat. But even so if u minus this wasted energy from the one which was needed to reach you to your destination it will be nearly the same ("nearly" because friction causes energy loss at higher gears). U can go and ask "Veritasium" himself if u doubt my brain. I'd love to get roasted by him if I'm wrong. I hope this ends the debate.

Actually scientifically it takes a different amount of effort because the human legs are not perfect theoretical energy sources. Human legs are most efficient in a narrow range of cadence, around 70-100 rpm. It uses less energy to do 50kph at 85rpm than it does to do 50kph at 40rpm or 140rpm. At 40rpm the force required is too high and it overloads the muscle, and at 140rpm the nerve channels become fatigued quickly and also the leg mass becomes increasingly a factor. Towards each side of the extremes of gearing, the nerves and muscles fatigue quicker, but for different reasons.

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.

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.

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 😊

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. Es decir no Hera necesario, por otra parte hay quienes han instalado platos descomunales para tener desarrollos mucho más largos. 2.- se requiere de mucha fuerza para mover esa trasmisión. Incluso los profesionales utilizan desarrollos mucho más cortos. Ejemplo Contrarreloj 58-11 (5.27 vueltas de rueda por cada vuelta de pedal) Ruta 53-11 (4.8 vueltas de rueda por cada vuelta de pedal) Xco 38-10. (3.8 vueltas de rueda por cada vuelta de pedal) Bmx (entre 2.4 y 3 vueltas de rueda por cada vuelta de pedal)

Two details. one.-. The first chainring has 48 teeth, the second has 39 and your sprockets have 16. According to the assembly, for each revolution of the pedal, 7.3 revolutions of the wheel are obtained. That can be overcome with a 60 tooth folding bike chainring paired with an 8 tooth BMX sprocket. That is to say, Hera is not necessary, on the other hand there are those who have installed huge turntables to have much longer developments. 2.- A lot of force is required to move that transmission. Even professionals use much shorter developments. Example Time trial 58-11 (5.27 wheel revolutions per pedal revolution) Route 53-11 (4.8 wheel revolutions per pedal revolution) Xco 38-10. (3.8 wheel revolutions per pedal revolution) Bmx (between 2.4 and 3 revolutions of the wheel for each revolution of the pedal

Con buen juego de engranes se puede incrementar las rpm de la rueda trasera. La limitante es que en realidad, mientras mas rpm se obtengan en la rueda trasera por vuelta de pedales, mas esfuerzo tendra que hacer el ciclista, asi que tendria que considerar este aspecto.

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
