@@DatHondaBoi223 you don't even understand how gears work, for some reason I don't believe you. O wait "dathondaboi" didn't realise you was only 12 my bad
The gear ratio its all that matters not necessarily the gear size. The gear ratio for those who don't know is basically the amount of spin that the wheel will do, and you get that number by dividing the number of teeth of the sprocket by the cog. In this case its a 102T sprocket and a 16T cog, so the GR will be 6.3 so for every revolution of the pedals the rear wheel spins 6.3 times. Also you can achieve gear ratios like this by using different sizes of sprockets and cog, like for example you could use a bmx cassette with 9T and match it with a 53T sprocket and you would get around the 6 revolution mark like this bike does but without fabricating any parts.
Tire size increases the speed front gear size increase the speed also rear gear must be the smallest that only exist in some bicycles if you can made smaller one do it the smallest the gear on rear tire is the more speed you get combined with larger tire on rear is matter fronter tire keep it small to reduce the weight
Looks like a bit of fun especially on down hills :) , it might be a bit hard on the knee joints on the flat though , but as others have said electric assist would make it really cool. Very clever making the gear mate , 10 points for innovation .
I have always thought of this combined with a pedal assist 250volts bldc motor hub to give a start and then the cruising will be much easier. Hope you try to make a project with electric pedal assist and try. It would be a great combination
I thought there might be flywheel action. The important ratio is pedal speed to wheel speed for how fast you can go. Engineers who design bikes use a lot of data. This might be visually entertaining but there is a reason most bikes have many gears.
When sprocket ratio gets change, there is a change in torque and rpm but power remains same... In short, in this case rpm increased but same time required torque goes high... End result - You get speedy ride but for short time only. After few minits, you get tired by applying more and more power....
True but imagine the speed you get get bombing down hill. The issue going down is that eventually you max out the speed because you can't peddle fast enough to overcome the rear ratchet (wheels spinning at a higher rpm than you can get it to using the peddles). This would be the fastest down hill bike provided you have a long enough hill. I want to ride it down spruce knob. Bet I could get it to 80 mph 😆
@@hikermichael9443 Good point but i'm thinking how could anyone drive this bicycle uphil? Got to have very strong legs for that. This is for fun but not for everyday use.
The one problem I've always had with mountain bikes is that the highest gear ratio was always way too low when going down steep roads. This solves that and then some! If only there were a derailleur big enough to allow switching to a cog that big...

Your max speed is always going to be limited by aerodynamic drag vs. power input. When the drag equals the available power there will be no further acceleration and that's your top speed. I should say "your theoretical top speed" because if your gearing is too low or too high you may not be able to reach that top speed. This applies to all vehicles, not just human powered vehicles, including aircraft. When drag equals power, you don't go any faster. I once owned a car with 147 hp and a ridiculously high top gear which would give 180 mph at the 6000 rpm redline. Needless to say the car would never reach the redline in top gear or go anywhere near 180 mph, unless it were driven on the moon where there's no air resistance.
@@alihasanashrafi6058 I think you just have to train yourself to pedal at a faster speed (turn the cranks faster). You are going to blow out your knees pushing that insanely high gear. I've been bicycling all my life and I have friends who have destroyed their knees because they never learned to use their lower gears and spin the cranks faster. But it's your choice.
That's easy to solve though, just draft fast moving vehicles and that'll take care of the drag problem. If you are feeling particularly adventurous get a buddy to fly a plane near ground level and give you a solid draft, you'll never want to draft a platoon again once you've experienced drafting a plane

This is an awesome invention the fact that you can maintain your speed with less effort is amazing. Saying that when starting from a stand still it is not easy to move. And many people think that the bigger gear you have the faster you go yes that is true but it doesn't necessarily mean that you will hit your top speed that simply means a "bigger gear take a lot less effort to move the crank and makes you go a little faster" but it doesn't mean you will hit your top speed.

I've studied on bike gear ratios for a long time and i'll drop my 2 cents. First of all there is a point where depending on its ratio, a huge gear might be beneficial as the longer you pedal the more torque you can produce at lower RPM but NOT significantly more horsepower which determines top speed, but it depends on the rider and the conditions of the road, tire pressure, saddle height and ride's mood. Most times if you are used to it you can achieve the same speed with much lower crank RPM than your lowest gear ratio, but even a slight slope can take away the benefits of riding calmly. I've used to have a top speed of around 50-52kph on a 26" mountain bike with 42t front gear, changed to 48t but regardless if some gears can come close to what they where with 42t, the effort it takes to accelerate or going over a slope or hill took away my physical ability to maintain as high speeds as with 42t even with the stamina being unchanged, however if i ride at lower speeds the effort it takes it's like i'm walking compared to revving the crap out of my legs for no reason. The only good solution for bike gearing is a CVT alike system like Nuvinci, because there are many factors that make the same gears not perform the same for a second time on the same cyclist, but all these come with many downsides. The rule is: Big gears = need more torque = high saddle height = decreased ability of high RPM = Less top speed. Decreased saddle height = Ability for more revving with high gear ratio = most times better acceleration and top speed = knee pain that lead to problems. Choose your side, that's all with bikes.
@@armanrocks8778 not all speeds are the same, every gear has a sweet spot where being extremely high or low gear ratio offers benefits depending on the rider's torque, if this was on my bike i guess i would be riding like nothing at about 20-25kph, top speed might be decreased. There's no such thing as fast or slow gear.
@@armanrocks8778 i bet you can run even faster but you walk at 5kph with the same energy it takes to pedal a bike to 15kph, almost everyone can ride a bike to 30kph for miles and when you stop you're sitting and it still rolls for quite a while, you can't do that with your legs. I'm not by any means a cyclist in my mentality, but i've used to do speedrun races and occasionally use it as transportation regardless if i use a motorbike and cars, but let's admit it's the most energy efficient thing a person can use to move under its own power.
I really like your idea that’s really cool I saw humor in that awesome creativity and I think it really would be cool but would not get kind of Tiring after a while as long as it has a free will and you can coast
I had a single speed khs one as my daily commuter and would put anywhere from 5-20 miles a day. I got the gear ratio up to like 48/18 after a few years. It was awesome and I could easily keep up with traffic, but eventually the torque stressed the frame and ripped the down tube in half just behind the head tube
Pedaling forces of any sort from even the most elite athletes won't cause frames to fail. Defective manufacturing is why your frame failed. 48/18 is a very common single speed setup
You can't tear a frame apart by simply riding the bike. Won't happen if the frame is good enough. Take a steel frame, muffed + welded would be best, those things won't break. They can bend but they won't break.
Interesante para combinar con un motor electrico en la rueda delantera que funcione como asistencia de arranque y despues recargue las baterias con la velocidad ,yo con entrenamiento normal voy bien a 25kph casi 15km continuos con eso llego a los 50kph y soy mas que feliz ,mas rapido me parece arriesgado ya deberia tener otro sistema de frenos y una suspension reforzada,pero no la veo mal para el que hace trayectos largos y planos

If you make the gear ratio so large, the RPM generated would be very high but what about the force required to start the movement? The bike needs to be very light but again at high speeds maintaining balance would be difficult. It would be better to install multiple gears so as to balance the torque and RPM .

NEEEEEEEERRRRRRRRRRDDDDDDDDDD
@@armanrocks8778 ultimately yes... He said just that and ANY engineer will agree
I gained +4 braincells after reading this comment and watching the video, thank you so much.
Uphills and headwind: hold my beer.
Exactly =)
I really like your idea that’s really cool I saw humor in that awesome creativity and I think it really would be cool but would not get kind of Tiring after a while as long as it has a free will and you can coast
Wow!-
You must be smarter than all the bicycle manufacturers! 😉
I had a single speed khs one as my daily commuter and would put anywhere from 5-20 miles a day. I got the gear ratio up to like 48/18 after a few years. It was awesome and I could easily keep up with traffic, but eventually the torque stressed the frame and ripped the down tube in half just behind the head tube
Exactly! 53/13 is hard to turn on. Gear in this video seems to be about 100/20
Pedaling forces of any sort from even the most elite athletes won't cause frames to fail. Defective manufacturing is why your frame failed. 48/18 is a very common single speed setup
You can't tear a frame apart by simply riding the bike. Won't happen if the frame is good enough. Take a steel frame, muffed + welded would be best, those things won't break. They can bend but they won't break.
@@patricklee8789 u guys don't ride.
@@henrydanhategan5613 All I do. Since I am 5 and I am 28 now. So 23 years of riding a bike if I want to go somewhere.
Sempre imaginava como ficaria uma baique assim com engrenagem ⚙ grande bastante velocidade legal mesmo
Haja perninha 🚀🚀🚀😂😂
Was expecting to see you flying along as in the Street hawk programme
Please demonstrate an uphill climb. We will all be waiting 😁
Sim, funciona bem em terreno plano e descidas.
Mas para aclives, leves que sejam, precisa descer e empurrar a bicicleta.
Eu ia escrever "como é que os fabricantes de bikes nunca pensaram nisso ?" mas ... seu comentário inultilizou minha pergunta.
O cambiar de plato 😮
It's gonna be really hard to get going from a standstill with such high gearing.
Looks fantastic youd never know
You should try climbing on hill roads :)
Bike muito boa para descidas.
Interesante para combinar con un motor electrico en la rueda delantera que funcione como asistencia de arranque y despues recargue las baterias con la velocidad ,yo con entrenamiento normal voy bien a 25kph casi 15km continuos con eso llego a los 50kph y soy mas que feliz ,mas rapido me parece arriesgado ya deberia tener otro sistema de frenos y una suspension reforzada,pero no la veo mal para el que hace trayectos largos y planos
la paciencia de este men es chingona
Very nicely made.
when i was a kid i welded a crank sprocket to a rear sprocket and had one to one gearing, slow 🐌 but easy off road riding. before the days of mountain bikes with lots of gears.
TE QUIERO VER EN UNA SUBIDA JAJAJA,ESTA BUENO
Must be fun riding it uphill.
Great use of the tools available, sure emailing a file out to a water jet cutter would have been easier, this old school ingenuity.
Would u compare the speed increase before and after, applying the same force?
That should be zero. Physics.
@@juliusfucik4011 I was saying comparing the max speed of the bike before and after the modification, applying the same force in both cases.
Quero ver na subida kkk
No lugar plano funciona.
no plano ja ta morrendo
bro thank u so much for this info my friends have good gear bike and they go super fast and now with this upgrade i am 10x faster than them
Ughh all I can think about is how much of a nightmare riding up hill would be with that thing
You would have to double the length of the crank arms to take off easier. The speed you could achieve with multiple rear gears would be impressive.
I think you might need a license at that point.
@@eyeseayew189 you might be right.
ey bruv you got a loicense fo that boike m8?
Saludos un gran innovación

You had a really cool professor at school ? Awesome 👌
Fully agree and support this idea.
Только вот незадача- это всё равно что тронуться на 5 передаче🤣
congratulations, I always wanted to make a crank like that.
You’re definitely gonna build your leg muscles up.
Commendable job 👏👏👏👏👏👏
Wow... Just WOW! Unlike all of the fancy guys that have metal working, do-it-at-home machine shops, this video could be replicated by almost ANYONE with at least 6 tools, many of which a friend or friends PARENTS could have! Very very very very VERY well done! My hat is off to you! I'd love to absolutely see the maximum speed of this bike on a flat street cruising alongside cars without the restrictions of a parking lot! Great job!
En las pistas bajó techo sería exelente ver la velocidad que alcanzaría los grandes ciclistas👽🚴 💯⚡💥💨
Totalmente!
Al aire libre en llano levante 54.4kms/hs con una mtb 05 18velocidades y las subidas con 2da y 3era alcanzo los 20kms/hs. Las bajadas e podido alcanzar hasta 65kms/hs y no soy profesional. Mi mtb es standar con agregados y con el cuadro de hierro, no aluminio, ni menos limado.
please show some uphill testing please...
Cool. Crazy. Like. It.
If you make the gear ratio so large, the RPM generated would be very high but what about the force required to start the movement? The bike needs to be very light but again at high speeds maintaining balance would be difficult. It would be better to install multiple gears so as to balance the torque and RPM .
Exactly
Imagina a força que tem que fazer numa pequena inclinação
It only last for 5 minutes then you need a huge rest break😂
@@TheHerrMan 😂😂😂😂😂😂
Se aumentar o tamanho do pé de vela agente consegue
Можно брать с собой такой диск для ровных участков
Например надо проехаеть несколько Км ровной дороги. Встаёшь где нибудь, меняешь свой обычный диск на эту громадину и едешь дальше
Правда на разгоне будет очень сложно
Las respuestas en todos los idiomas xD.... supongo que antes de llegar a la inclincacion debes agaarrar mucho impulso antes.
It must be pretty exhausting riding that bike. & I'd say it'd be impossible going uphill. Good experiment though & well done on the modification work.
Eu tinha um Speedo Peugeot antiga, com coroa maior de 52 dentes, ela era uma bike muito veloz pneu traseiro tubular feito de um tipo de lona emborrachada, 110 libras de pressão, eu nunca consegui por o pedal leve, chegava a mais de 100 km por hora, está aí nem numa super descida vai ficar com pedal leve!
Pra linha reta descida e otimo velocidade imenca quero ver subida fica extremamente pesado.esse tipo de coroa lugar planos onde tem muita subida nao funciona
Wow I'm amazed it's not hard to pedal, and what about going hills I bet that is much harder, but still a clever build.

No its very hard to pedal , I already tried in my cycle..
It’s not a problem, jumping down off the bike & and walk.
Классная задумка. Супер, а теперь попробуй на нем в гору подняться))
i need this when i was kid to defeat all my friends in one bicycle race
