- This video explores some of the challenges in designing early bicycles and how concepts such as wheel circumferences, gear ratios, and torque were used to solve problems.
I feel that the engineering of bicycles is a great way to connect some basic mathematical ideas into mechanical problem solving. Playing with properties of circles and ratios as a way to make a bike move faster builds a context to bring these geometric ideas into something physical and creative.
The story also shows how creativity and engineering don't follow a linear path. Seeing novel solutions, failed experiments, and missed opportunities give us a great framework to inspire us and guide us through new problems.
it’s insane this doesn’t have at least a million views, extremelyyyy well done !!!
i once read, the bicycle is amazing, in that the engine, the passenger and the driver as one person all contribute to its motion.
Yep
Really good video! Needs more views for sure
3:14 you could use a middle gear so it can turn the last gear in the right direction. No chain drive needed.
Underrated video! Should’ve gotten a million more views
thanks!
Internal hub gears pre date the derailer as a viable multi gear system by a good 20 years if i think correctly
It's making a comeback with belt drives.
This video is fantastic and easily deserves millions of views.
One of the best videos I've ever seen
Thank you - really appreciate that.
Beautiful illustrations..really great work
Cool educational video with cool animations, loving it.
Thank you!
This video is criminally underrated
Thank you. My work doesn't seem to get much traction on TH-cam.
@@reasonformath Dude, why though
Good vibes video and nice animation. Perhaps Gentulio Campagnolo should have had a credital mention when speaking about the history of bicycling inventions related to gears.
This video is a great breakdown of the engineering concepts behind bikes! Great work!
Thanks so much!
Amazing video, I will certainly show this to my students, thank you
Thanks! Please tell them I say hi.
This is very well made.... I loved the video, keep making more I want to see many more such knowledgable videos!!
Thank you! More animations are on the way...
@@reasonformath I am waiting to see those ! Again awesome work ! Could you make videos about cars as well ?
I watched this video randomly years ago.
It finally happened.
I was asked "Why did they make those bicycles with that large wheel?"
I CAN PUT MY RANDOM LATE NIGHT SCROLLING KNOWLEDGE TO USE!
Glad it came in handy! And glad the explanation stuck with you.
Great video !

1:26 the original mullet!
This visualizes various concepts way better than most cycling channels ever did. Maybe a video on engineering lost/ignored could be nice. Bikeracing never accepted recumbents or aerodynamic fairings. Whether the geometry, especially Highspeed downhill, is ideal is also questionable given the rules squeezing racebikes into certain dimensions. Motorcycle racing once featured dustbin fairings for great aero. I assume thats more related to less power making topspeed a more important component, but if they were in fashion in racing they might be for normal motorcycles making them more efficient. When i look at cars I don't think the 4 seat arrangement comes from a place of logic either but rather as evolution from horse drawn carriages. I know a certain width is necessary to not fall over but outside of racing context seating people behind one another seems better. Just that at the point aerodynamics started to really matter, speeds got high, the layout we know was too established. Or so i assume.
Bikers of the world: Unite! You have nothing to lose but your chains! I see the bicycle as being a stride amplifier.
Wow, awesome video of bicycle history!
Cool animations! A couple small nits though - the ancient greek weapon 'polybolos' had an endless chain drive as far back as 250BC. Also, I think bicycle makers in the day of the penny-farthing had definitely conceived of using a chain drive. Many of the women's tricycle designs in that same era had chain drives for example. If you look at old photos the chains look pretty big and heavy though. I'm guessing that it just wasn't as practical back then with the chain technology of the time - and combined with the lack of pneumatic tires a large wheel was just a practical, simple, and affordable option.
He was actually on to something with the butt cone. There’s wind tunnel data that show significant aero improvement when there’s a large saddle bag on the bike. More than making up the weight.
It would be really interesting to ride with one of those and see if you can feel the aerodynamic difference. I would just worry that a cross wind would come in and turn the butt cone into a sail, blowing you off of your bike. 😧
Great video i enjoyed it. Very much but was very short and missing needed informations
Thanks! The main purpose of this was to go over some main geometric/mechanical mechanisms such as wheel circumference and gear ratios, not really cover a complete history of the bicycle.
the video is great, 1 point though. you start each new chapter with a summery of the last, while just finishing the last. it feels as though the videos were made separately, then connected together. no need to repeat information 10 seconds later. for example, chapter 2 is about the sprocket and chain, chapter 3 explains that again at the start.
Thanks. And I did make this originally for my TikTok account and it was in three pieces. I assembled these together and didn't want to have to recut new audio and generate updated animation.
I still think this is the greatest invention of all time.
i don't think , i believe is the best invention.
Cool animations! Great explanations! Amazing video!
You skipped the multi-speed rear wheel hub entirely..... Your history cannot be right.
You skipped the word “brief” in the title.
Beautiful animation.
Thank you!
Jean Loubeyre of Paris. He indisputably patented a 2 speed derailleur device called 'La Polyceler' in 1895 (French Patent and shimano took over being 100 years old now derailleur was invented well before 1937
Is the electronic groupset/shifter the new standard for Tour De France road bikes?
Very interesting, thank you
Incredible production here
Thank you!
Great stuff, thanks
Fascinating!
Excellent video.!
Thank you!
Thank you for this excellent video!
You're very welcome!
Amazing production
Thanks teach!
Because I have limited knowledge of bikes I can't do this project maybe you can
Gears were meant to be put on a wheel for you to exercise your arms same as a leg arm Exerciser
So when you move the wheel with your arms you start at a light weight and after a certain number of turns you increase the gears strength so your arms moves a heavier weight
This is how people get muscles
They lift small weights and then heavy weights
The advantage of wheel with gears is you don't need the weights and can put on muscles anywhere
Let me know if you understand
Thanks for the video
learned so much! thanks
Great work
What? I can't believe that aerodynamic butt cones are not a thing today.
I know, Someone should start a GoFundMe to bring back the butt cone.
This was awesome. Thank you
Thanks so much!
thank you for this amazing video
Thanks so much!
I think butt cones need to make a comeback, if only for the photo ops.
Interesting and informative - but surprised no mention was made of hub gears, developed in the early 1900s.
hub gears?
Rather surprising that you showed Leonardo's chain sketch without even mentioning the bicycle drawing attributed to Salai...
Bike radar has the storey and a 2 gear rear wheel system amd rear derailleur like an old front mech was used in 1869
What about the bearings? I heard ballbearings were invented for bicycles. True?
Incredible
Oh this is excellent
Great video thank you
Perfect!
Amazing video
Thank you!
Fantastic
This is amazing
Thanks so much!
3:14 why not just use an idle gear in-between?
And now I want a but cone riding my bike after watching this vid.
1817 the Swiftwalker created by Karl Von Drais is the very first bike. 🤔
Why is the resolution 1x1?
The aspect ratio is square because I first posed this to my TikTok account, and a 1:1 aspect was a good compromise between the default horizontal aspect of TH-cam and the vertical of TikTok.
Didnt campy invent the derailleur?
Good animations
Back then, derailleurs were considered cheating.
1970: front suspension was considered cheating.
1980: having rear suspension was considered cheating
2018: having a electric motor was considered cheating.
I'm thinking the pinion gearbox is definitely gonna be considered cheating
how about tire?
My favorite "toy" .
Very impressive, now the future for bicycles are the gearboxes
Three cheers for the butt cone!!!
whoa
Wait, so the bike chain was invented by da vinci? Damn.
The butt cone should be reintroduced.
The ending 😂😂😂
❤❤❤❤
There's a 900yr old temple in India with a bicycle carved in granite, on it. I dont think your time line is correct somehow.
Yes, there certainly was an even earlier version of the bicycle that didn't have pedals, you had to walk on the ground like the Flintstones while riding it. It was invented by the same person who invented the meat grinder.
@bikee1394 just not sanitation 😄
Inventor Karl von Drais , thanks to him i no longer have to waste money in gas on a gas engine vehicle.
Can I suggest you really need to give thanks to John Kemp Starley...from my home town in Coventry, UK.
So... what about that butt cone?
Now you are just talking dirty.
(Do it again)
💪
It's 3:38am for me right now why am I watching this??
I refuse to believe people though first in doubling the wheel size than to do a chain, gear or belt drive.
When presented with the problem of "it's hard to steer the wheel you're pedaling" the immediate solution is to move the pedaling to the other wheel.
I hear you. The most obvious solution is easy to see with the benefit of hindsight.
And yet we have hi-tech derailleur systems that occasionally drop our chains \o/
😊😊😊😊
I got drunk one day and tried to ride a penny farthing.
I fell down and broke my coccyx, cocxyx? Coxyxc?
Ha ha! I always wanted to write the word coccyx, coxyx, cocoyxx? In a comment! Am I the first person to write the word coccyx? In a comment? Let me know in the comments!!!!
Did you have to wear the butt cone? 😂
The biggest problem is theft, 1/2 due to cyclists themselves underestimating the risk by not using a Ulock & registering.
Engineering 101 for preschoolers
4:10 early masher
Just so you know people are stealing your video putting it on tiktok and recieve million of views
I do have a TikTok account as well. If it's @reason4math on TikTok, then it's me.
I have seen my work stolen all over (especially on Instagram), and I appreciate you alerting me.
HALLO
Probably should study a little bit more. There’s proof of bicycles for hundreds of years before the pf . Solid European perspective
lot of nonsense about higher CogG being "harder to balance"
actually the reverse is the case - the higher the CofG the easier it is to balance
I know it not only from the theory, but also from practice 😜
With a higher center of gravity, smaller shifts in weight have a bigger impact. I ride a unicycle, and the short ones are easier to balance than the tall ones since a small movement in the arms is less apt to throw you off balance.
@@reasonformath I have no personal experience of unicycling, but I am sure the same applies. As you say "...With a higher centre of gravity, smaller shifts in weight have a bigger impact..." i.e. it requires less effort to keep bike balanced - th-cam.com/users/shorts5C6cid5RBk8?si=v3IB2rtnwmVISp0L 🤪 I know how much more difficult it is to do the same on lowracer recumbent... 👍
A bit too much repeating the same facts but cool video.
