Great and fun project, but reading the comments, I don't think people really realize how hard it would be to be cycling on that bike! 😂
You really don't want headwind on that bike!
Or bumpy roads to go to
Let's not forget there's no brakes
@@ShayanGivehchian I think there's a brake on the rear wheel, a common coaster brake. You can see the brake arm attached to the frame at 5:20
Not at all. Just have to be sure everywhere you ride has at least a 10% grade, all tail wind, and a freshly paved road and it works like a champ.

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).
how can I do math to know the relation between tooth numbers vs rpm ?
That’s when you get a assist motor or full on electric motor. 🤷🏼
@@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.

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.
That's called a 21 speed. 3*7 = 21.
@@shawnpitman876I know that it is 21, but speed regulators are located on the left and right sides. So, in my language, it's called differently.

Those are called "gear shifters." One changes (shifts) the front sprockets, the other changes the rear sprockets.

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.

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
@@VadimDober not the kind you want to use at that speed I think 🙂
Love your skill and effort to transform normal bike to a super fast one 😮😮😮
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 !

cool, I always wondered how big that crank set would have to be get crazy speeds like that. What angle was the hill??? I went 60 KPH ounce, the hill. It had to be about 25- 30 deg. Pedalling down hill was always my favourite!!! Nice video!!!
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
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.

If only I wish could’ve be even if I got time but there’s no care
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.
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 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.
WOW! I nearly filled my shorts going down a steep, curvy two-lane road at 37 mph! 800 ft drop on one side, trucks on the other.
@@vickanid1862 Whew, that sounds scary, too. Trucks and a 1/6 mile drop are nothing to trifle with.

Oddly, it's a semi-popular place to bike. It really gets the adrenaline pumping!!@@gusmartinez4518
Such a large gear ratio, it means that in the start, you would need a tremendous torque (force from your thighs) to start your cycling, otherwise, the only way to move the bike from rest, the only way is to roll down a inclined road. This would have been better, if you could switch to this gear, once you've built your pace with a smaller gear ratio...
If you think starting is a killer, imagine trying to stop it by counter pedaling on a fixed gear cog. It's gonna be considered a war crime.

This is a man of focus, dedication and sheer effon will
This is an idea that I was thinking for a long time. I need this king of build on my bike.
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.
I always wanted that setup on my electric bikes since over 35mph I can't spin my gears fast enough to contribute and just pedal for show lol.
well, you could use motorcycle or something.
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!
You could use a shimano 11 speed 48x11, and it would be much easier.
I don't think any derailer can compensate for the chain size difference
Where did you get the teeth for the front sprocket
These video editing skills were eye soothing to watch, oh and nice bike :D
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.
But just think how fast you could go with the wind !
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.
@@judelachance lmfao !!!!!!
@@patricj951 you need to prove it wrong with a video or people won't believe you.
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.
@@teropiispala2576 hey mate, what's your Strava in the (very) low case you aren't bullshitting?
@@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.

I can imagine you can use this to travel between 2 cities if you only used the highways.
And if you had a separate chain and gear for regular city travel for the shorter distance you needed
NOOO my fav TH-camr was sucked into the NFT realm
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.
God have mercy if you ever have to climb a hill with that setup! 🤣
when you go 0.1 degrees up hill on that its done lmao. but love the work you put into it

Just a bit under 40 MPH, not bad. I love watching the talented, off-the-wall people on YT.

He did that on a downhill though, no way you're getting 40mph on flat while it looks like he's not even putting in any effort

It's an interesting idea, I used to think something like this might work before I tried pushing top gear on a standard road.
That is what I called an upgrade, from level 1 to 100 already. Great job. 💯

Ok I’m sorry, but why is there a turn at all in a hill that lets you go 70?
@@aeeeea8169 I don't think the turn was on the hill, it was someplace else and they happened to be at 70km/hr because of the hill

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.
To boldly go where no man has gone before!
My knees started hurting just from the thumbnail
man! you got some muscles!! people must know how hard it is to pedal that thing and to reach such speed
He has not close to the muscle mass required to make gain of such a high gear.
40 mph downhill is easy.
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
and here we don't really see how was the road for the max speed: flat or slope? 😅
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.

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.

@@Blox117 you also have monkey pox
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.
Speed is the biggest dividing line but weight is also a consideration. The first motorcycles were simply motorized bicycles anyway.
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.
Bro just casually made the equivalent to a 1000hp car but in a bike
Glad to see we not the only ones who thought of this and understand why thisbl is good
What a great build, great concept, great result.
Cool! Would love to see this in cvt form so you could start in a lower gear ratio and ramp up to that
Yeah. Where I live, the hills would prove to be prohibitive.

this is crazy in a good way. always wanted one
Great editing and sound. The skills and the concept are fantastic. Thank you for sharing this with us.
I didn't realize there was a brake in the rear hub and I was impressed how he could skid that ratio.

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
Very good Brasil 🇧🇷🇧🇷🚴
Só faltou ativar a legenda português Brasil 🇧🇷😻.👍
So he made a single speed, super high gear bike that you can only ride downhill. Brilliant.
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.

You just need to paddle backwards or reverse
But these paddle brakes are not easy as handbrakes
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.

There was a bike rider called "Mile a Minute Murphy" who built a bike like this around 1900. He wanted to eliminate air resistance so he drafted the fastest land vehicle that existed back then: a train.
The railroad built a fairing on the back of a passenger coach to shield murphy and his bike from the wind and decked two miles of track between the rails.
He sustained 60 MPH like this (96 km/h), but other than all the bones he would have broken if something went wrong, it wasn't a lot different than doing 60 MPH on a treadmill!
Imagine crashing on a road with that bike then that giant disk would literally slice off ur leg
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!
