A Brief History of Bicycle Engineering

[@xopurp]

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

[@BHALT0S]

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

[@Coastal_Cruzer]

Yep

[@SuperFinGuy]

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

[@jun-yuncharliegreen8743]

Really good video! Needs more views for sure

Very impressive visuals for a homade KZbin video, I wonder if you would be keen to show me your software, this is great for my cartoons

[@reasonformath]

Thanks! I've worked in the visual effects industry for over thirty years now, so I've built up a pretty big bag of tricks for working in CG. For this animation, I used Autodesk Maya with Adobe AfterEffects for assembly and color grading.

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.

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!

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

[@reasonformath]

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.

[@Frankienoname0]

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.

[@reasonformath]

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. 😧

[@danielreitermusic]

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.

[@joefields719]

1:26 the original mullet!

[@gur262]

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.

[@adrian_zombturtle148]

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

[@asadabdulqaabir4006]

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

[@reasonformath]

I know, Someone should start a GoFundMe to bring back the butt cone.

[@Emtbtoday]

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

[@simonlevy00]

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.

[@reasonformath]

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.

[@cheesechomp3r554]

Why is the resolution 1x1?

[@reasonformath]

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 KZbin and the vertical of TikTok.

[@vinniepeterss]

[@macsnafu]

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

[@fuerLutzi]

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

[@frankhooper7871]

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

[@Cheesicle_]

hub gears?

[@Lucius1958]

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

[@srilankanlk8652]

you forgot the breaks. by the way nice video

[@jamesmatheson9624]

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

[@chillchilli2671]

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

[@danielchesley9802]

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

[@lese39]

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.

[@reasonformath]

I hear you. The most obvious solution is easy to see with the benefit of hindsight.

[@maxmarrero-sb5ej]

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.

[@jaykay3407]

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.

[@Diwasho]

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.

[@jaykay3407]

@bikee1394 just not sanitation 😄

[@GbpsGbps-vn3jy]

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

[@DavidGS66]

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

[@bambukouk]

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 😜

[@reasonformath]

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.

[@bambukouk]

@@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 - kzbin.info5C6cid5RBk8?si=v3IB2rtnwmVISp0L 🤪 I know how much more difficult it is to do the same on lowracer recumbent... 👍
