A Brief History of Bicycle Engineering 

i once read, the bicycle is amazing, in that the engine, the passenger and the driver as one person all contribute to its motion.

Really good video! Needs more views for sure

Greatest transportation machine ever invented

Cool educational video with cool animations, loving it.

Underrated video! Should’ve gotten a million more views

Beautiful illustrations..really great work

3:14 you could use a middle gear so it can turn the last gear in the right direction. No chain drive needed.

Great video ! Recumbent bicycles Were considered Cheating and were Outlawed by the Tour de France After a recumbent Rider beat all others On upright bicycles

This video is a great breakdown of the engineering concepts behind bikes! Great work!

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.

Bikers of the world: Unite! You have nothing to lose but your chains! I see the bicycle as being a stride amplifier.

You skipped the multi-speed rear wheel hub entirely..... Your history cannot be right.

This video is criminally underrated

This is very well made.... I loved the video, keep making more I want to see many more such knowledgable videos!!

Dude forgot include internal hub gears.. famous 30 years prior derailleurs

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.

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.

Wow, awesome video of bicycle history!

1:26 the original mullet!

Very interesting, thank you

Incredible production here

I still think this is the greatest invention of all time.

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 teach!

Is the electronic groupset/shifter the new standard for Tour De France road bikes?

learned so much! thanks

Cool animations! Great explanations! Amazing video!

Great stuff, thanks

Fascinating!

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

Excellent video.!

Thank you for this excellent video!

Great work

This was awesome. Thank you

Oh this is excellent

3:14 why not just use an idle gear in-between?

Why is the resolution 1x1?

Bike radar has the storey and a 2 gear rear wheel system amd rear derailleur like an old front mech was used in 1869

Rather surprising that you showed Leonardo's chain sketch without even mentioning the bicycle drawing attributed to Salai...

whoa

Good animations

Great video thank you

Interesting and informative - but surprised no mention was made of hub gears, developed in the early 1900s.

how about tire?

Three cheers for the butt cone!!!

Very impressive, now the future for bicycles are the gearboxes

The ending 😂😂😂

1817 the Swiftwalker created by Karl Von Drais is the very first bike. 🤔

❤❤❤❤

Didnt campy invent the derailleur?

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

😊😊😊😊

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.

It's 3:38am for me right now why am I watching this??

💪

Inventor Karl von Drais , thanks to him i no longer have to waste money in gas on a gas engine vehicle.

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!!!!

The biggest problem is theft, 1/2 due to cyclists themselves underestimating the risk by not using a Ulock & registering.

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 😜

Probably should study a little bit more. There’s proof of bicycles for hundreds of years before the pf . Solid European perspective

it’s insane this doesn’t have at least a million views, extremelyyyy well done !!!

Internal hub gears pre date the derailer as a viable multi gear system by a good 20 years if i think correctly

What? I can't believe that aerodynamic butt cones are not a thing today.

The butt cone should be reintroduced.

So... what about that butt cone?

Amazing video, I will certainly show this to my students, thank you

I think butt cones need to make a comeback, if only for the photo ops.

Wait, so the bike chain was invented by da vinci? Damn.

Beautiful animation.

Great video i enjoyed it. Very much but was very short and missing needed informations

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.

One of the best videos I've ever seen

What about the bearings? I heard ballbearings were invented for bicycles. True?

And yet we have hi-tech derailleur systems that occasionally drop our chains \o/

This video is fantastic and easily deserves millions of views.

A bit too much repeating the same facts but cool video.

Engineering 101 for preschoolers

My favorite "toy" .

Incredible

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

Fantastic

Perfect!

Amazing video

Amazing production

4:10 early masher

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.
