You deliver the maximum torque to the wheels when your crank arm is at an angle of 90° wrt to applied downward force (i.e. when it's horizontal to the ground), and 0 torque when crank arm makes 0° angle (when pedal is at it's lowest and highest positions), hence the relationship between crank arm angle and Force is "T = F*Sin(θ)" where T is Torque, F is applied downward force, θ is Crank Arm angle.. now the wider the diameter of the crank set, the more Force you need to apply, since T = F*sin(θ) increasing F, increases the amplitude of the sin wave very sharply, hence when θ= 90°, you'd need to put A TON of force in order to even move forward.. hence this thing can only be used on horizontal ground, if there's any slope, you're dead. Thanks for reading have a nice day.
Oh got the more the diameter of the crank set the more force needs to be applied..and it would be not be quite possible to go up slope with This type of bicycle but what about going downhill it would catch momentum quickly and at its top speed ig..(im not a genius, just an idiot tryin to learn basic science 🙂✌️)
That gear ratio will take you to much higher speeds than in the video, if you have the legs to push such a large gear. Wind resistance will quickly be a limiting factor. 53*11, which is a pretty common gear to have, yields over 70kph at 120rpm with a road bike wheel size (700c).
@@despairangel7209 That's easy. pedals_rpm*front_teeth/rear_teeth*tire_outer_diameter[in meter]*pi In this case 120*53/11*0.7*3.14=1270[meters/minute] Now just divide by 1000 and multiply by 60. Voila, 76 km per hour.
Ooo blast I didn't even saw that the brakes were missing. I am becoming suspicious of the whole video, just a question : could you even start up with such a gearing ? The tires creates a natural rolling resistance when they flattens because of the driver's weight
I used to cycle everywhere and had extremely strong legs. I was on the lookout for a bike like this, because the gear ratio on my bikes didn’t challenge me even in the fastest gears. Unlike my friends who were into high reps to maintain speed, I liked to use the fastest gear and pedal less revolutions, taking advantage of my strength. I never was able to find anything like this back then. Wish I had, though maybe not quite as extreme.
Once, when I was young and in shape, I was on a remote highway, on a slight downhill grade, with about a 15-20 mph tailwind, and I managed to hit a top speed of 55 mph, pedaling just as fast as my legs could go. That was a cadence of 120. 😂 (2 revolutions of the pedals every second, if you do the math.) I do know that for sure, since my bike computer I had at the time also read cadence, with an extra sensor… Sure would have been fun to have had a higher gear ratio. Like you said, I didn’t have much torque available at that speed. If I remember correctly, I had a 50t chainring, but my smallest sprocket in back was only 13, I think, since I was running an old school freewheel. I since upgraded to a cassette hub, but I’m not in great shape, partly since I hardly get out and ride anymore. 😖
you could've gained the same effect by going to a small sprocket connect to a larger sprocket on an independent axle in the middle of swingarm before going to the rear axle. That would've saved weight, be stronger, and far easier to produce. However, the bike wouldn't be as eye catching at first glance.
I remember riding about 55 mph(88 kph) down a hill on my 1985 12 speed Fuji, and, with it’s super thin tires, I felt every revolution of the wheels with the slight imbalance created by the tiny presta air valves. Scary, cuz’ it was on a 2 lane highway and I had to keep looking back to see whether there were any cars coming behind me. Though, it would have been awhile before they caught up to me.
Reminds me of how I used to do speed training throughout the entire summer during its holidays. Almost every day, from morning until evening, I would try to ride as fast as I could. My bicycle wasn't really expensive and cool; it was just quite light and had 3*7 speed modes (I don't know how it's called in English). So, by the end of the summer, I was riding on a straight road and gradually began to catch up with a scooter. A little time after I overtook it and realized that I was faster than the scooter. I was in total shock. Well, the guy who was riding the scooter also looked at me like, 'What on earth is this?!' Of course, it was a low-power engine scooter, but it's still one of my highlights.
I've always liked the idea of a faster bike for use as an alternative commuter vehicle. It would be nice to see it used with something like a Shimano nexus 7 speed hub to ease the run up to pushing such a large gear.
although this seema like a good idea i expect it would lead to either too big a weight increase (geared hubs tend to weigh a lot) or lead to people sitting in the lower gears, however if they were still willing to push that hard then it shouldn't be too much of a speed decrease. thing with this bike is that you're forced to go pretty fast!
It doesn't matter how big your equipment is and what its gear ratio is. What matters is your power, wind resistance, your slope and the tire profile and air pressure. If you are very strong and ride downhill and into the wind, on racing tires with very high air pressure, you can reach over 100 km. In flat conditions you will not exceed 60-70 km.
Shalmi Sandlar, Correct. And for those speeds you mention it requires huge legs, like a bodybuilder or track cyclist. This video is just one of several misleading videos in the topic. The gear ratio on the bike in this video is way too high for even the strongest human unless in downhill or tailwind.
Next up is to replace the crank hub with a planetary gear. Go even bigger on the possible overdrive ratio, and you don't have to screw up the frame geometry for ground clearance. And since the chain ring itself can be more normal sized, you'd still an easier time with chain tension and alignment to keep a standard rear gearset as well. (I think it's been done at least once already, but not something I've seen visited as the subject of a video.)
Truvativ did exactly that for mountain bikes about ten years ago. It was called the Hammerschmidt, and it was a crankset with a planetary transmission. It gave the same ratios as a 24-36 t with a single 24t chainring.
I have driven 80km/h on flat with normal road bike, and I didn't even use highest gear. One don't need extreme gear ratio to get into such speeds but some training to get pedaling ratio up while maintaining decent torque. It needs power to get into high speeds and power is torque times RPM.
@@hugoyoung4890 I don't have any and no longer be fit to drive that fast. As a reference, I'm more muscular than typical cyclist and I liked to train by driving uphills as fast as possible. There was lots of them along my regular routes.

As a manually pedaled bike this would be torture to ride but I could see and e-bike that has a gear like this being a thing, although that raises the question of where the line between e-bike and motorcycle falls.
Here it is a motorcycle if it has more then 500w continuous power, allow the electric engine to help you at higher speed then 25km/h and if the electric engine pushes you without pedaling... Other then that it is considered an electric bicycle according to the European rules.
The stress on the chain must be insane. Building up speed with this is also near impossible unless gravity helps (downslope). That said, looks incredibly fun
You can do the same thing by adding an extra free hub cassette on top of the main crank and have it run through that. Have your crank run through the seventh gear and then have your rear wheel run through the first gear. It's just a simple gear reduction and you don't have to have that silly huge chain ring. Just add an extra cassette free hub on top of the crank and weld it to the frame. Looks a lot better too. Probably just as hard to peddle.
This is surprisingly good as an instructional video on bike maintenance/bike moddimg/power tool use. Great camera angles that show the details on everything you do, even stuff like oiling the grove for the metal sheet hole cutter
have hit around 70 MPH not sure exactly what that is in KPH but it is sketcky as hell. was a straight downhill no turns and road was very smooth or would not have dared try to go that fast.
Damn, I know I'm a year late to this party, but I started this video out super excited, it was a fun concept, you opened it on a bike with a gorgeous frame with some real hipster commuter potential and then you announced an NFT project. It's too bad I didn't get past the first forty seconds, I bet the rest was cool.
The rest of the video was just a montage of using various power tools with a very short clip at the end riding it, all with no commentary. He doesn't say a single word after the nft ad, you didn't miss very much.
Если уменьшить лобовое сопротивление, то можно добавить ещё 5-10 км/ч, и при столкновении поймать ещё больше переломов. Снимите видео как на таком велосипеде ехать хоть в небольшой подъём.
I've cooked wheel bearings on a large downhill with no traffic. Did about 50MPH, before the slowdown and a slight squealing noise. To bad it was in the 1990's before getting that kind of mischief on video was a lot easier to do. Just a plain ol' hybrid style bike too, nothing all that special about it. Kind of dumb luck I never got into speed wobbles or anything more unexpected like that.
I've gone 80 kph with a 54 x11 on a modern time trial bike. It was on a short down hill segment on Strava. I set a kom that still stands nine years later. It was too big a gear for most purposes and I ended up going to a 53 x 11.
80-85kmh is normal speed for steep downhill (5%+), but you need to produce enough power to rotate pedals at that speed with cadence about 120-140 rpm (about 500-1000Watts). I think more efficient is to lie down to top tube and handlebars at 75 kmhs and relaxing with cool wind around of your body/)
I like my 56t. I don't really feel the need for something bigger, and in flat terrain or slight uphills I'm always on the 11t. Wind resistance is really what limits the power you can turn into speed. A rider with beastly legs could power something bigger, but he could also use that power to get a higher cadence with the 56t, as many do. As for your 80 kph, at that speed pedal input plays no part. Only up to maybe 60 kph at most. With my 56t, at 40/50kph I'm struggling to increase the speed in flat terrain, and it's not because of a too high cadence. It's just my power limit I guess.
although I love this channel and the fun builds that you do here, I unfortunately am unsubscribing due to the association with NFTs I wish this channel all the best!
Amazing engineering minds..!! What a compilation of the flawless work.. hats off genious..!! This reminds me I have clean my cycle. Pending since last friday
The lack of aero wheels makes me sad, but still a cool bike! The fastest I have ever reached was 102 km/h going down a mountain. 64 on the flat is impressive!
Love it. I saw a bike in a museum many years ago that had a smaller sprocket on front and it achieved some sort of speed record, but they drafted behind a vehicle/structure. For your own humor, you might want to try drafting behind something just to see what you can do. Really nice construction and video shots. I'm subscribing now.
Man went thorugh all this work, but forgot to put lube on the fork and quill stem when putting the bars back on. And he spray painted the bottom bracket, but no lube when applying the pedals.
@@UserT5959 Normal bike and hard to pedal bike build the same muscle. Is you spin this slowly is the same as if you spin a normal bike at normal pace. Even going uphill and downhill is the same if you put the same Watts of power in both ocasions.
Bro acted on an idea we all had since the day we figured how bike gear works ! I always wondered how far could you go in term of disc size difference but never expect such a HUGE difference. I expected air barrier to block you way sooner. We don't see the actual footage so 64kph is still hard to believe but glad to see is gear ratio does work ! I feel like a long-time itch has finally been scratched.
5:40 pause and you can see the front and back wheel in completely different orientations. The frame is wickedly twisted. This guy's got a lot of courage to ride at those speeds
Sketchier things have been done. My favourite is the saw bike. That's a real health hazard. Falling off a bike and burning skin on pavement is nothing compared to falling on that saw.
The trick to putting the wheels in is with the bike the right way up and weight on the bars, otherwise, when you tighten the nuts it goes off at an angle. I think this is basic bike shop, junior mechanic stuff learned from working on 'bicycle shaped objects' (cr4p bikes).
@@pdsnpsnldlqnop3330 your just use your left hand holding the tire and frame while your right hand tightens the nuts, been doing this since early 70's. It's called common sense, but common sense is not so common these days.
That is an insane bike! His welding destroyed the strength of the original tubing. The enormous chain ring makes it extremely hard to start and stop and with no brakes, anything getting in his path will result in a catastrophic crash! I have ridden a good quality racing road bike at 80 km/h and it had normal racing gears and brakes so it is much easier to ride and not nearly as dangerous!
Increasing the potential power output is one aspect, but bicycles heavily depend on the weight factor too, Power to weight ratio. That front chainring looks like it potentially doubled the weight of the bike. Having no brakes saves weight but it may not save your life!
Some pedals with longer arms, perhaps they will help you to exert a little less force to turn the plate. The leverage effect by moving the distance away from the axis of the toothed chainring would certainly help. Good job.
I had an idea to do something similar, except it was not as refined as the large wheel model you have. It was inspired by a larger size front sprocket that an old friend had placed on a Schwinn he sold me. I believe in the future there will be a mechanism which can be placed on mechanical objects which will increase the fluidity and finess of it's operation, possibly electromagnetic. We're about to bust through old paradigms in many ways. Already have in some instances.
I once have a similar idea to increase the bicycle speed. But what I come up with is using multiple gears. From what I've learned, it will probably be heavier to pedal the bike with that one big gear, and it would also happen by having multiple gears. From there I'm thinking about using hydraulics to help pedal the bike. I don't know if that method will work or not, I don't even have designed the mechanism, I just have been thinking about it 😁. I do not have enough knowledge yet and also resources 🙃. My initial idea is to make eco-friendly land transportation that runs only by pedaling and I hope it won't emit emissions, just pure human energy (as our effort for making the environment healthier). I was trying and hoping to design it to be as fast as the average speed of a car but this time without any engine 😅
Problem with that is the human body does not produce enough torque to pedal at such a high gear ratio. Same with this bike, the moment he were to encounter even a slight uphill and he'd stall out. Hell, if you're going for "as fast as the average car" which in the modern era is at least 100mph you're going to hit the lack of power problem from air resistence alone, without even thinking about an uphill.
Well that's stupid plan. No matter what you do and how many gear ratios you add, our body has a limited power output and you cannot go fast simply by adding bigger gear or using hydraulics. I can do 60kmph on my bike without that big gear wheel.

That gear ratio will take you to much higher speeds than in the video, if you have the legs to push such a large gear. Wind resistance will quickly be a limiting factor. 53*11, which is a pretty common gear to have, yields over 70kph at 120rpm with a road bike wheel size (700c).

The stress on the chain is only about half the body weight if you drive standing. On a normal bike the stress is roughly double the body weight.
you just need bigger legs i think
The stress on the chain is insane.....ly low. Compared to a normal bike it's almost nothing. The larger the drive wheel, the less torque.

This is an idea that I was thinking for a long time. I need this king of build on my bike.
You can do the same thing by adding an extra free hub cassette on top of the main crank and have it run through that. Have your crank run through the seventh gear and then have your rear wheel run through the first gear. It's just a simple gear reduction and you don't have to have that silly huge chain ring. Just add an extra cassette free hub on top of the crank and weld it to the frame. Looks a lot better too. Probably just as hard to peddle.

Ok I’m sorry, but why is there a turn at all in a hill that lets you go 70?

have hit around 70 MPH not sure exactly what that is in KPH but it is sketcky as hell. was a straight downhill no turns and road was very smooth or would not have dared try to go that fast.
Damn, I know I'm a year late to this party, but I started this video out super excited, it was a fun concept, you opened it on a bike with a gorgeous frame with some real hipster commuter potential and then you announced an NFT project. It's too bad I didn't get past the first forty seconds, I bet the rest was cool.
I did the same, opened it excited and saw NFT and immediately thought "I cant support this".
The rest of the video was just a montage of using various power tools with a very short clip at the end riding it, all with no commentary. He doesn't say a single word after the nft ad, you didn't miss very much.
Same bro, I thought it was a joke at first, but alas it wasn't. Oh well

@@Apple_Beshy scared of going downhill at just 20mph ? I use to ride on my mtb on plain roads everyday at 28mph , afterthat gears sucks 😅
I've cooked wheel bearings on a large downhill with no traffic. Did about 50MPH, before the slowdown and a slight squealing noise. To bad it was in the 1990's before getting that kind of mischief on video was a lot easier to do. Just a plain ol' hybrid style bike too, nothing all that special about it. Kind of dumb luck I never got into speed wobbles or anything more unexpected like that.

I've gone 80 kph with a 54 x11 on a modern time trial bike. It was on a short down hill segment on Strava. I set a kom that still stands nine years later. It was too big a gear for most purposes and I ended up going to a 53 x 11.
I've done 85.3 kph down slack hill in Derbyshire
On a 14-inch wheel bike 🤣
I got speed wobble and cars were driving behind me 😱
80-85kmh is normal speed for steep downhill (5%+), but you need to produce enough power to rotate pedals at that speed with cadence about 120-140 rpm (about 500-1000Watts). I think more efficient is to lie down to top tube and handlebars at 75 kmhs and relaxing with cool wind around of your body/)
I like my 56t. I don't really feel the need for something bigger, and in flat terrain or slight uphills I'm always on the 11t. Wind resistance is really what limits the power you can turn into speed. A rider with beastly legs could power something bigger, but he could also use that power to get a higher cadence with the 56t, as many do. As for your 80 kph, at that speed pedal input plays no part. Only up to maybe 60 kph at most. With my 56t, at 40/50kph I'm struggling to increase the speed in flat terrain, and it's not because of a too high cadence. It's just my power limit I guess.
Remco just used a 60T chainring in his Vuelta time trial. Get him on this bike.
doesn't strava auto hide dh after that fella tboned a car at like 50 mph?

Amazing execution. With an electric motor to help with starts, this bike would be unbeatable in the city.
which app was used for measuring speed
That's the bike I will build for my own! Now I know this is a masterpiece.
The lack of aero wheels makes me sad, but still a cool bike! The fastest I have ever reached was 102 km/h going down a mountain. 64 on the flat is impressive!
I was disappointed with the knobbies they put on it too. A bike like this should have something like 700c x 22 road tires, not knobby tires.
the whole drive train has too much drag anyway
And the sprocket is a little heavy adding unnecessary weight
Какой Вы умница 👍Уважаю таких👍Взял и сделал 👍🤗
Polina, do you like Putin?
Love it. I saw a bike in a museum many years ago that had a smaller sprocket on front and it achieved some sort of speed record, but they drafted behind a vehicle/structure. For your own humor, you might want to try drafting behind something just to see what you can do. Really nice construction and video shots. I'm subscribing now.
Man went thorugh all this work, but forgot to put lube on the fork and quill stem when putting the bars back on. And he spray painted the bottom bracket, but no lube when applying the pedals.
I didn't realize there was a brake in the rear hub and I was impressed how he could skid that ratio.
I/m wondering how the wheel still rotating while skidding...?
Amazing idea. Good work bro!
Absolutely loved it, this bike is perfect for me to train 💪 wish it was affordable

Bro acted on an idea we all had since the day we figured how bike gear works ! I always wondered how far could you go in term of disc size difference but never expect such a HUGE difference. I expected air barrier to block you way sooner.
We don't see the actual footage so 64kph is still hard to believe but glad to see is gear ratio does work !

Getting in on that NFT scam money, way to go.
It's an interesting idea, I used to think something like this might work before I tried pushing top gear on a standard road.
5:40 pause and you can see the front and back wheel in completely different orientations. The frame is wickedly twisted. This guy's got a lot of courage to ride at those speeds
holy crap you're right.
Sketchier things have been done. My favourite is the saw bike. That's a real health hazard. Falling off a bike and burning skin on pavement is nothing compared to falling on that saw.
the haphazard alignment taking the frame together shows at 5:40
The trick to putting the wheels in is with the bike the right way up and weight on the bars, otherwise, when you tighten the nuts it goes off at an angle. I think this is basic bike shop, junior mechanic stuff learned from working on 'bicycle shaped objects' (cr4p bikes).
@@pdsnpsnldlqnop3330 your just use your left hand holding the tire and frame while your right hand tightens the nuts, been doing this since early 70's. It's called common sense, but common sense is not so common these days.

That is an insane bike! His welding destroyed the strength of the original tubing. The enormous chain ring makes it extremely hard to start and stop and with no brakes, anything getting in his path will result in a catastrophic crash! I have ridden a good quality racing road bike at 80 km/h and it had normal racing gears and brakes so it is much easier to ride and not nearly as dangerous!

The larger the front crank, the more power required to move the bike forward.
That's what I waited for ❤️🚲⚡
Thanks for watching 👏...Contact 📥⬆️ something special for you
Increasing the potential power output is one aspect, but bicycles heavily depend on the weight factor too, Power to weight ratio.
That front chainring looks like it potentially doubled the weight of the bike.
Having no brakes saves weight but it may not save your life!
@@mms5789 I was more concerned with the safety aspect than the weight saving!
These video editing skills were eye soothing to watch, oh and nice bike :D
Rah, imagine the power one will need to pedal this monstrosity.
It'll probably take like 5 mins just to get to half speed😂
Bom trabalho, agora sobe uma ladeira 😂👏👏
Some pedals with longer arms, perhaps they will help you to exert a little less force to turn the plate. The leverage effect by moving the distance away from the axis of the toothed chainring would certainly help.
Good job.
he would get slower
The problem with extending the pedal is that the cyclist legs would start going too much back and would probably be very uncomfortable at some point
the NFT ad definitely dates this video
I had an idea to do something similar, except it was not as refined as the large wheel model you have. It was inspired by a larger size front sprocket that an old friend had placed on a Schwinn he sold me. I believe in the future there will be a mechanism which can be placed on mechanical objects which will increase the fluidity and finess of it's operation, possibly electromagnetic. We're about to bust through old paradigms in many ways. Already have in some instances.
I once have a similar idea to increase the bicycle speed. But what I come up with is using multiple gears. From what I've learned, it will probably be heavier to pedal the bike with that one big gear, and it would also happen by having multiple gears. From there I'm thinking about using hydraulics to help pedal the bike. I don't know if that method will work or not, I don't even have designed the mechanism, I just have been thinking about it 😁. I do not have enough knowledge yet and also resources 🙃. My initial idea is to make eco-friendly land transportation that runs only by pedaling and I hope it won't emit emissions, just pure human energy (as our effort for making the environment healthier). I was trying and hoping to design it to be as fast as the average speed of a car but this time without any engine 😅
Problem with that is the human body does not produce enough torque to pedal at such a high gear ratio. Same with this bike, the moment he were to encounter even a slight uphill and he'd stall out.
Hell, if you're going for "as fast as the average car" which in the modern era is at least 100mph you're going to hit the lack of power problem from air resistence alone, without even thinking about an uphill.
Well that's stupid plan. No matter what you do and how many gear ratios you add, our body has a limited power output and you cannot go fast simply by adding bigger gear or using hydraulics. I can do 60kmph on my bike without that big gear wheel.
Is it just me whos surprised that he made a hybrid bike out of thin air?
Hybrid literally means 2 engine. This isn't a hybrid under any definition. It is still a road bike as well.
@@skylerstevens88871. A hybrid bike is a mix of 2 or 3 bicycles such as a mountainbike using road components and bmx tires

Brilliant bit of fabricatioin! Bravo. How are the brakes -- I think you have a hub rear brake that's getting a lot less torque than its used to! Also, set your seat a little higher for more comfort. It was a pleasure to watch your fabricatioin & I enjoyed the photography. I liked the interior view of the pipe while its being cut and full of sparks. Your video also has a wonderful pace and suspense: It doesn't get bogged down with too much detail and the whole time something new is always happening. Thanks.
