- I'll show you how to transform a super-fast bike with multiple chainrings, and it's got really big gear ratios, so it's super fast!
My channel has just started, there will be more interesting DIY productions in the follow-up

50-60 km without brakes! Great idea!
It's a fixie, a fixed gear bike, to brake you have to stop pedaling
@@eljigui9131 if you think about it though the gear ratio works in reverse too i think i haven't ridden a fixie before but if the gear ratio works in reverse then you get the same amount of torque back and it has very little torque so you're better off stopping by just letting air drag slow you down.
@@eljigui9131 Check back to where he puts the chains on...
@@eljigui9131 If you stop pedaling at like > 30km/h it will break your shin before slowing down a bit
@@eljigui9131 no it isn't.
The most impressive thing is that it has no brakes!
Good project!
Edit:
Thank you so much for the likes, I would never expect this!
Also another thing that amazed me through this time, is how many people don't know how bicycle brakes work!
probably coaster brakes
@@ethan944
I thought it also, but I didn't observe any bracket protruding from the rear hub
He made a bike built for.. *speeeeeeeeedddddd*
CAUTION: brakes sold separately. Lol
That is weight reduction
Just said for speed, never implied for safety lol
The ultimate bike, which can lead to you to hospital faster than the ambulance. He is going 50 kmph on a bike without brakes.
This gear chain is ingenious yet simple, got me amazed.
I'm pretty sure it is super hard to pedal this bike or even impossible on uphill.
honestly just starting to pedal on this thing on flat ground seems painfully hard
@@giancahe8202 running start bro
that's why you get a hub motor on the front for electric assist
@@kingmasterlord Might as well get a road bike at that point, and they're faster.
Infact he was on descent
I’d say this is comparable to launching your car in 3rd gear (assuming you didn’t stall). You’re gunna turtle for several seconds before any speed happens. Probably takes quite a bit of leg strength to initially get going. Awesome!
I mean, get it up to 45MPH and it'll go up that hill, so long as the hill don't last too long. XD
So what direction would you go with the ratio? or, does anyone even know what the ratio he has now is lol. 😆
@@kennethferguson9828 presumably you’d do what actual bikes do, which is have a derailleur so you can start in a low gear and adjust the gear ratio as you need to.
pair it with a wheel hub gear box and you should be good to go.
That's the thing you WILL 100% stall if you launch your car at 3rd
Before welding, the paint should have been removed. Also, rather than cut into the frame of the bike to add the hubs for the two new sets of sprockets, new pipe should have been welded onto the frame to add the hubs. Cutting the frame to weld in the hubs creates the possibility of the frame not being aligned perfectly straight afterwards, which adds structural weakness.
Also, gear ratio is way too high unless you do serious biking. I used to bike 24 miles every morning (took me two hours), my legs were huge, and I doubt I would have been able to get that bike going without struggling, or starting from the top of a hill
This thing is just meant to have the highest gear ratio he could think of without making a front gear the size of the wheel itself. It's a proof of concept, not a product.
this is a chinese channel did you really expect them to do anything right
@@logandunlap9156 : It is often when you underestimate your opponent that you are best crushed by him.
Probably 10 to 11 gear ratio. Seen higher....

Best idea was to leave the bearings inside the bottom brackets for welding. Next best idea was the spray paint job. Everyone knows, orange chain makes you faster. But hey, it's a fun project, so good job 👍

It's true, ask lightning mcqueen
Its a tough call for me between the 2 you mentioned, and sloppily hole saw-ing chunks out of the frame members.
how to get speeding ticket using bike:
Thank you! Its like you did the experiment for me. I'm currently putting a similar arrangement, with shifters on a stretched frame.
This concept was my mini project with my team in college and we did it back @2013.
It's still inside the college workshop since then...
Can I have it?
Do you ever ride the bike?
Because it didn't work- nobody can go faster just because of higher gearing. In fact it would slow you down until you drop down a bunch of gears.
How did if feel?
So it is really difficult to start the bike with such a high gear ratio?
Can't even imagine how hard it would be to pedal this thing on slopes.
Nicely done though
And poor knees...
Did you calculate the drive ratio? Must be silly
3:04 love the music!
Since there is no gear shifter belts rather than chains would be much better 🙂
Cool build was fun to watch.
On such a bike, you would be more limited by aerodynamics and slopes. On a hard flat surface it would be very fast, any slope would cause you to slow down and eventually stall out.
Take a while to get up to speed though.
@@BlooCollaGal Only normal to think that tbh
Can’t imagine the torque that’s lost from that ratio
I bet there's a market for this bike in The Netherlands then :D.
@@Mike-739 Just imagine the leg gains...
Others are appreciating his hardwork but I'm shocked to see no brake on the bicycle with such great speed 😶
I am more shocked to see the original built quality of this bike. Ouch.
Pfft mean while Street kids and teens in my country has rusted chains and no breaks while wears flip flops and challenges each other to a drag race.
@@JomokFelasco
R u from Brazil or Phillipines or Indonesia or any other ?
If you want to build a higher speed bike, i cant think how adding breaks will increase speed of the bike... 😀😀😊
@@mmeettwwoo It increases the possibility of being able to ride it again and again
I tu dopiero mogę się spodnie w łańcuch wkręcić 😁😁😁😁😁
Now I want to make this bicycle too so I can ride to school on time
imagine a chain falls out and he's going downhill with no brakes at a really fast speed
⚰️
And they look a lil loose too, not so sure about this one
@@Raging-Lion yeah don't try and go up a curb, you'd lose all the chains haha
He spins the peddle backward to test it. I don't think it has breaks even with the chain.
Well, let's hope there's enough room to maneuver at the bottom of the slope
Now let's see it go uphill😁
Awesome! Let me buy a hole saw, some gears, some extra chains, welding equipment, oh and a bike ... Wait I have a car...why am I thinking about this?
Nice idea for speed lovers
unless your legs are extremely powerful one gear reduction is enough - it makes for a more simple design with only 2 chains instead of three
I was thinking 2 sets of pedals. One set like normal bike, the other for high speed. Then you could switch between conditions (uphill-downhill etc.). Upper pedals might have smaller cranks. But then simpler to have e-bike..! :)
@@RJSoftware2000 that is actually a good ideas, a separate gear ratio for different speeds and possibly different riding positions based on the speed
@@then00brathalos or you could use a bike with a rear durrailer and even use the third and second gear on the reduction stages with front durrailers. That last idea would unfortionally make for a very complicated gear change setup with up to four shift levers.
@@then00brathalos Yeah but having that many moving stuff would reduce efficiency due to more frcition, would make the bike harder and more expensive to maintain, and would have more failure points, better to just have rear and front durrailers
you can actually use the weight of legs to pedal it is not as hard as it looks
Got to love the spray paint lube on the chains!
The whole point of this project was to make a cool video, so of course some of the painting choices aren't the most practical.
People that skips arm day: *Climbing a hill with this will be my goal*
That huge front sprocket @ 2seconds is insane. I've seen REAR sprockets dang near that big on the back wheel of dirt bikes which must top out at about 7 mph. Lol
Yeah, but with that much torque, they can probably climb walls!
Quite a long number of years ago, Hot Rod Magazine had a article about a guy setting the bicycle paced land speed record. They built a shed on the back of a car, seems like it was a supercharged '58 Chevy. The cyclist pedaled inside the shed while the car and shed pushed the air out of the way. That bike had a front sprocket bigger than a pizza pan, as I recall.
Lmao at those load bearing freewheels, this is wild
for a speedy bike, and low torque, its perfect for the Netherlands
I can feel my legs getting bigger watching this
52 kmh is still acheivable on a stock 3:1 gear. However you need about 500 watts of pure power to maintain such speed, which is much greater problem, than not so convenient ratio

so many nerds in the comments who can't seem to appreciate a lighthearted engineering project
A speed bike with no brakes. Great XD
Cool build all those chains and no need for a single chain tensioner cool
Because it is single speed. But somebody has to pull/push him to start.
Ride any standard race bike and you'll find it already has gear ratios higher than what you can usefully pedal. With these enormous ratios the amount of torque needed is beyond what your legs can supply so you'll actually go slower than with a lower ratio. Air resistance limits speed on a bike as it goes up exponentially with speed.
with this i feel like i can outrun the dog that always chase me next street
Finally I saw your cute face in serious mode. 😂
I’ve always wanted to do this! It’s so cool to see it in reality! I also wanted to apply these principles to a generator.
These principles in generator, really?🙄🙄
Generator requires huge torque to rotate the shaft. This setup didn't work for genarator.
@raydubBALTANseijin It does apply, but in the opposite way of what you want in a generator generally
@@sandeepvardhan7583 Generators are powered through induction, which makes little to no resistance. So if you have a high torque, you want to convert that to speed before you get a good current off it.
What effect would that have? it would still generate the same amount of power
@@ashrude1071 More friction, more parts that can wear out
Fast bike! I'm sure that fitting one of the gear wheels in lieu and place of the saddle would have made it even faster!
As a kid we would also ride bikes with no brakes. To stop all you need to do is put your wedge your back foot between the tire and the frame. It'll wear your shoe faster but works just fine.

I love how he’s going 50mph on a bike and has no brakes
I think that's 50kph, so 30mph.
50kph =/= 50mph
Easy to do when you're hyper-focused
This is my end semester project 😊😊
You'll only be disappointed when you try going over 15kmh or so.
Legends closing their eyes during welding
Ever heard of a cassette with different gears? Great invention...
Then finally I realised that when Im going that speed,I forgot to make brake system.
Regardless of the efficiency, you've made a rideable art piece!
Not so "rideable" without brakes
What do you mean by efficiency? A pulley system reduces the force that needs to be applied to get momentum. You get more speed with less force applied. I don't get it what's the problem with this ?
@@MybeautifulandamazingPrincess probably efficiency in general, for example the human effort that takes to start up the bike to a reasonable speed
Brave and ingenious man!!! Also smart for that helmet :)
this is the bike for the person who forgot leg day xD
I was actually thinking of doing something like this, thanks allot buddy for the ideas on position of where I can put the bottom bracket 😺👍 subscribed I bet that was a good workout getting that up to speed, I know it would of been for me lol
Frankly, gearing has never stopped me from reaching maximum speeds, it's always been aerodynamics and pulmonary / cardiovascular capacity...
@@rey_nemaattori Agreed. If anything gearing helps because it's possible to squat 400lbs compared to 20x20lbs in a second... Also agreed, it's always my cardio endurance that fails first; it'd have failed at lighter ratios just for the aerobics vs intensity. My cardio has always been terrible, hate it, hate it, hate it.
@@GRAYgauss Gearing absolutely helps, but it always is a trade off in power required per stroke. Eventually you're going to need so much power it simply becomes impossible. Especially since you're not just pressing 400 lbs in a second, but _every second_, thats when either fatigue kick in, the muscles can't move the load or the body can't supply enougj oxygen.
For most people it's easier to press 20 lbs for 20 seconds that to press 400 even once .
@@rey_nemaattori Eh, bad numbers on my part. I was imagining squatting and that force that goes into pedalling when I go up hill. My point is that the human body can't move fast enough to pedal 20lbx20 in 1 second, but we COULD pedal 400lbs once in one second. For me, it's easier to pump more per cycle than many cycles, because I have terrible cardio but good mass/strength ratio.
Bad numbers again, but that's the idea...The balance in my mind is most efficient when biased towards 20% speed and 80% max force rather than 80% speed at 20% force. Agreed with what you said on power, but for me I'm biased to feel that high speeds are more impossible than high torques. The fastest I can go isn't when I'm peddling like a demon, but when I'm taking about 5-6 seconds per foot to torque through and the entire follow-through feels like a rocket acceleration.
the Gen 2 for this should be set to let you shift into a low range for the initial start and going uphill
You never see him actually start up so he's likely getting a push from a friend to get started. Fun idea though!
4x the chance of ur chain slipping off lol
Надо на верхнюю цепь защиту приколхозить, а то даже шлем потом не поможет. А так вполне годно.
да нифига это не работает. По прямой на фиксе и без этой ерунды можно разогранить, не говоря о простых велосипедах. Там потери энергии просто фантастические, не говоря о том что в горку эта конструкция вообще не заедет, да и толкать эту шарагу даже по прямой долго не сможет человек без подготовки.
Самоделка полная хуйня, и я объясню почему. Вваривание в раму, в нагруженный элемент тонкостенных алюминиевых картриджей кареток - это настолько тупо, что просто разрезать раму пополам и так оставить. Люди выкидывают рамы дорогих велосипедов, когда на них появляются меленькие трещинки и боятся их варить, посколько сварной шов или пайка будет тянуть металл на себя, создавая избыточные напряжения, которые могут привести к новым трещинам. А тут он алюминиевую фольгу в раму захреначил! Так еще и нагрузку на это дал! Я вот такую тенденцию замечаю только у азиатов, чаще всего у индусов. Они берут велосипед и всеми правдами и неправдами повышают передаточное число, прибегая к таким методам, от которых сопромат впадает в ступор, и пока он из него не выйдет, конструкция работает.
А, забыл спросить. У вас там вообще подъемов нет?
Есть более простые и надежные способы увеличить диапазон скоростей. 1) замена переднего чеинвилла на побольше, но не как на Мелиде автора.
2) все.
Если МТБ чеинвилла не хватает, ставишь шоссейный или циклокроссовый.
Если и этого не хватает, продаешь мтб и покупаешь шоссер. В кармане опустеет на несколько месяцев вперед, зато не сдохнешь от проникновения переебаной рамой в брюхо.
Ни какого КПД я в этом не вижу, можно сказать только минусы .

not that fast
47kph, which is about 30mph, not bad at all
@twin7s
Well it's been geared up loads so I would have thought anyone could get it up to that kind of speed
@twin7s i agree, i hit a top of 30mph on my bike on flat land (i am locked out of the two hardest gears ‘cause racing regulations)
@@BillSikes. it would be a pain in the ass to get started though.
That is not a speed bike. That is a power cyclist you got right there.
The secret to going faster on a bicycle is to pedal faster.
there is, however an inversely proportional correlation between torque and gear speed... since it can go faster, that also means it takes a ton more effort.
I was honestly thinking how much force you have to put into actually getting it moving, since at such a speed he was peddaling pretty slowly
@@stefan-viorelnagy5181 he wasn't actually going as fast as the speedo showed- he altered the speedo settings to look faster.

The real question is how many watts is he outputting to get that speed. He's fighting a lot of wind as well
due to his riding position.
Hes descending,maybe around 300-500 watts
Es muy impresionante, pero al tener mayor velocidad es necesario tener mejores frenos verdad ?

More speed = more energy
Bikes work that way. You'll see that once you get a gear bike, the higher the gear, the more speed, but the more energy is needed. The lower the gear, the less speed, but less energy is needed
Would be interesting to see it with an electric assist
Imagine if there was a motor and you can change the gear to make it slower or faster. Since it's a bike with a motor, I would probably call it a motorcycle.
Probably not a very good idea, putting that much load on a motor for that long will overheat it and reduce its lifetime and also reduce efficiency , kind of like you don't start your car at 4th gear, assuming you could even get it started at that gear. You can try out something similar at home if you just buy a simple 3V motor and power it up and then hold the shaft of the motor tight for like 2 minutes, you should notice it getting at least a bit hotter
Imagine if they could do that with selectable gears. They could make them in 18 or 21 speed configurations. And maybe put all the gears along the hub of the rear wheel for a more ergonomic design. That would really be something if someone could design that.
just add a CVT at this point it could be the first CVT on a bike maybe
It's a cool little project, but this shit is slower than a cheap road bike lol
Imagine someone stealing this, You'll never see it again lmao.
Us Aliens Have Hoverboards
What would happen if someone did that, but he/she also put a big gear next to the small gear on the back axle with another chain attaching the big gear to the chain drive? Will there be both speed & torque or would one cancel the other out in the process.
it would cancel out
Thats a crank
