КПД не ахти ещё.Пункт 2. Можно подобрать материал и грамотно его обработать.но и цена этому есть(если это будет сделано специалистами)." Улучшенные зубчатые колеса изготовляют обычно из качественных углеродистых сталей 35, 40, 45, 50, 50Г и легированных сталей 35Х, 40Х, 40ХН и др. Нормализованные зубчатые колеса небольших размеров выполняют из углеродистой стали обыкновенного качества Ст5, Ст6 и качественных углеродистых сталей 35, 40, 45 и 50, а больших размеров - из углеродистого стального литья 35Л, 40Л, 45Л, 50Л, а также из марганцовистого н низколегированного стального литья различных марок. Для повышения контактной прочности зубьев и соответственно нагрузочной способности зубчатых передач применяют стальные зубчатые колеса твердостью НВ>350. С увеличением твердости рабочей поверхности зубьев возрастают также износостойкость и сопротивление заеданию зубьев. Однако зубья с большой твердостью рабочей поверхности плохо прирабатываются и нуждаются в высокой точности изготовления. Кроме того, их механическая обработка затруднена, для облегчения ее эти зубья нарезают до термической обработки. Так как некоторые виды термообработки вызывают коробление зубьев, то для исправления формы зубьев применяют отделочные операции: шлифовку, притирку, обкатку и т. п"(с)

This man solved the problem of dirty chain very simple way.

@@mareksykora779 Shaft driven is old technology, chain came later. Shaft driven cycles were ruled out due to high loss of energy during transmission.

@@unclsam6798 Again for you: It solves the problem of always dirty, lubricated chain. Can you understand the sentence?

​@Sky NinjaHave you ever ridden a bike, dude? Your pants will get dirty from the lubricated chain in the middle of the chain. Here, the middle part of the shaft is hidden inside the frame.

@Sky Ninja Its about city bike, not mountain bike. Find yourself Brikbikes channel. They produce bikes with shaft instead of chain.

And was soon abandoned.

Hahaha we going backwards!!

Can't make up something new do a reboot. Lol

if I recall it was also patented by Iver Johnson a typewriter machine company

The great great grandma of the prototype 😁

No it's a braindead design.

I don't think it has better efficiency as chain has efficiency of up to 98% if I remember correctly. The other 2 I'm not so sure, can't remember the details. I believe what you are thinking of is belt driven bicycle, not shaft driven bicycle. Cool tech is still cool though, so I'm not gonna judge

There are public bike rental schemes in Portland OR using shaft drive bikes using 3 speed shimano hubs

@@SuperSohaizai That's the same as what he said. Reread his comment. The chain is more efficient.

@@firesurfer oh kay.... I actually misread it until you pointed it out... Thanks, and my bad!

@@SuperSohaizai I figured that when he wrote: " shaft-driven bicycles with better performance, efficiency". Without the context of the entire sentence, it can easily be misread.

👍👍❤️

We can have foot rest for this purpose

Yea u are right man

But you can stop by paddle without brake like Fixed Gear Bike.

Rear axle has ratchet system...he can stop pedal even when it is moving...am I wrong...?

Just what I was thinking!

It is trash, he just made a good mechanism 1000 times worse and turned it completely useless.

To do this, you need to lubricate the mechanism, I had an electric saw where the same mechanism was used, I forgot to lubricate it and as a result, after a week, the links were erased.

Yeah, no bearings or grease in that tube, so good luck.

I cant speak for bicycles but in motorcycles a new chain is more efficient than bevel gears but actually research shows that chains lose efficiency rapidly as they wear. On a bicycle I guess that's less of a consideration. That's one reason you've seen more motorcycles move toward using belts and gears in recent years, along with lower maintenance. Obviously with a bicycle gearing is a substantial consideration that favours chains. 👍

And another is that he can't rest his foot as the wheel rotates with the rotation of the pedal,unlike the chain system

There are many more disadvantages to this. When you put a lot of force on the pedals, the smaller gear will be pushed out, away from the other gear with great force. In the way he currently welded the tube, the connecting plate will just bend open, losing any contact between the teeth. It's also much more difficult to do gear shifts, more likely to get something like a long dress or a coat being pulled into the gears, and probably a lot more.

And some way to keep your shins when going downhill.

I think this mechanism is more suitable for ev

@@ompatel5226 how?

@@srinivassiddarth he could use different transmission ratio and then use another gear at rear with motor

Maybe he can improve it in the future

this is actually is like truck on 1st gear. So you need to pedal more for to go faster but now you have more torque. So if he can do a double or triple gear system that is changeable it will be better than chain system I believe :D

That's why when they used to make bikes like these, back in the 1800's they quickly ditched them when derailleurs started appearing. Chain reigns supreme.

Not a power loss.more like a efficiency loss due to way to low of a gear ratio. But he could climb any hill slow.

@@kevind3185 Slow indeed, pushing the bike i.e. walking it.

No even in cars they use shaft to maximize the power in bike they use chain becoz bike is more efficient in fule economy to reduce the cost of shaft and it is also less maintenance I know your indian science student becoz iam also indian 🤣🤣 mai ne bahut Indians ko deka he har video ke niche uska science dalte baite he 🤣

@@wicked9299 car mein shaft use hota hai because it needs more torque as it is carrying lot more weight compared to bikes. Also the inner and outer wheel needs to rotate at different speeds while turning this is difficult to achieve with chain drive.

​@@jckdnls9292Crafted a video with 40 mil views and counting.

👍👍👍

i think it is possible to integrate the same mechanism present in the rear gear set into the current one if he did not do it yet, that way you can just let it glide, but true you have to pedal more than in a normal bicycle, and I would like to see if it is possible to add something transmission like to this mechanism, and I guess it is not impossible, but will definitely be time and money consuming, but I thing the end product will just be worth it

Any video,we want to see.

Do a video on it. Even if its like 1 minute

Yes, man had a bicycle shop and in 1982 they made these and the gear would eat out going down hills, 1983 they put a inline slip to fix that, Shop owner took this one out of box and hung it up in store till I bought it 10 years ago. Has the old new tires on it, looks like any bicycle 10 20 speeds, has a cable from center pedal up along the frame to curve down to front wheel and chain drive on back, I bought it because it was different, dark green paint with plastic gear where this one is steel

BWA 2 wheel bicycle, on RU-vid, not mine but would work the same way, made for ridding in sand

Can I ride it?

I had one, it also had 6 different gears! This is not an original idea as you said!

exactly

Well, he still built it himself. There are also bikes with no inside. So what? Still pretty damn cool imho

Very cool recreation of the original shaft driven bicycles. It's crazy to think that about 120 years ago, bicycle manufacturers successfully produced and sold bikes with these features.

Okay, where's the one you built? THAT is the point of his videos. He built it himself - pretty cool

It's like mocking chains because you saw someone who's running a 22/52t spinning out once

You're assuming the chain is what creates the power ratio's, where it's actually the gears. You could have an equally powerful push with an appropriate sized gear. Hence why geared bikes have different sized cogs, not chains.

Chains are messy, relatively short-lived, and wallow in road grunge. Driveshafts (as motorcyclists well know) are neater and require almost no maintenance. The drawbacks of shafts for both motorbike and bike are initial cost, more weight, and less efficiency than a chain. I think the trade-off is often worth it.

@@rcnelson the friction loss must be crazy but true tbh, chain suck sometimes especially when they come off and you have to stop and put them back in, but ill keep my chains your opinion is valid though

@@joel7227 that actually makes alot more sense ngl

Shaft driven bicycles are over 150 years old. They were abandoned for the chain as the chain is vastly superior.

I heard some company's trying to make an automatic transmission for it tho

What’s the point of backpedaling tho I rather use it for a hard brake like in a 1 speed city bike

@@bobmorane2082 different speed acceleration and efficiency

@@bobmorane2082 for those who aren't used to it it can be a detriment, also breaking isn't very easy on fixed gear bikes, I'd say their for experienced riders only

I don't think it is mechanically efficient as a chain and sprocket.

But if he combine both shaft driven and hubless bike together, the bike would be very2 slow

True

Yeah you'd need alot more gears

@@stavid7870 that's just a chain but worse and more delicate

Different size gears would fix that, this was a first run so he had to have some baseline. Wouldn't be hard to correct.

In the motorcycle world bigger sprocket= more torque smaller=more top end

Yes

Well there's a reason why shaft driven bike didn't took off

But as same as belt drive you don't have to worry about grease or dirty oil on you're leg. Mamachari or japanese bikes has all three of them in the past don't if they still have em today

So shaft driven is ideal for exercise?

@@brijlal973 if you don't like wind in your face

Gear box - could be 50% loss

Actually, he has a coaster brake, so I'm presuming he put the drive gear for the rear hub attached to that, meaning if he stops pedaling, the wheel is able to stay turning.

That and maybe a housing for the gears so things can't get damaged and I don't know if you would have to lube it often

This was for demonstration purposes only. The rest is obvious 😎

Same question but i think its for demo only

At least a lot of torque for uphill driving

I wanna see it going uphill

you just made that up, stop talking shit. try a more factual approach next time. for example, this can not change gears... the pedals can not freewheel... etc

@@bottomline99 you could easily add a freewheel to a shaft drive set up ..

@@bottomline99 Actually, bevel gears (or any gears) are less efficient because there's a change of direction - twice in this case. Any force vector reqiures energy that ultimately is not delivered to the wheel. Where that's also true of a chain, the angular deviation is minimal by comparison, and is mediated by the difference in sprocket size (proportional to the gear ratio). So "made up" or not, the assertion is correct. Also, tensile strength may be greater than yield strength, it depends on the material. However, this is unlikely to matter as the forces required to either twist or pull a 5/8" steel shaft to the point of damage are unlikely to be achieved in this application. That said, I agree that the two major omissions are disengaging the pedal (freewheeling), and providing multiple gear ratios. All-in-all, a chain drive using a modern derailleur to achieve a nearly linear transfer of force while providing a wide range of input-to-output ratios is hard to beat.

@ Patricia Lorentzen In my opinion the lower efficiency of bevel gears a simple matter of friction, which increases at 90 degrees with the inherent increased surface slipping that results (Agree with JMC on that). Respectfully disagree about the vector statement, eg a long belt drive that twists 90 degrees is virtually as efficient as if it didn’t. It was ‘The reason they don't make bikes like this is that steel is stronger in the pulling direction that the twisting direction’ that inspired my comment. That is not the reason, it urkes me when people just make shit up and preach it like fact! My thoughts and guess would be, for the same torque transmission, the chain style spreads load over a larger diameter cog and many teeth, the bevel gears are a smaller radius with only one or two teeth in contact, which undoubtedly results in much higher stresses, requiring higher quality materials, hardened surfaces, shimmed exactly to avoid wear, enclosed with oil (and seals) to achieve low friction, a variable gear ratio wheel hub drive. imagine its actually pretty good system performance wise however simply more heavier, complex, costly to make and maintain compared to the ole cheap and effective chain drive that won.

Nerd. 🤣👍

Not his idea, this is already an existing idea from 1900s

Yeh, it needs to have a clutch and a gearbox.

Those are the same two issues any fixed gear bike would have and they're still hugely popular. The biggest issue here is just ease of maintenance. Too easy to switch out a chain or cog or chainring compared to this. Shaft drives have been around longer than chain drives, bmw motorcycles and some others still use them. Shafts on a bicycle are only about 75% efficient where as chains are closer to 95% which is another issue.

Let's call a bug as a feature, you can reverse a bicycle now

@@JohnNy-ni9np Then add a motor too otherwise u die trying to make this shit move...

I'm not an engineer (flunked out), but I can see a few flaws. It needs a freewheel mechanism, the gears are unprotected from the elements, the driveshaft bearings are just tapped into the tube with nothing to keep them from getting pushed in too far, the crank gear is offset and unstable, and a kid on a Razor scooter could outrun that gear ratio. The sad thing is, this is a great concept! It just needs to be properly built. :3

No way can matter actually it's working thats will more efficient

@@intelligenceroboticworld2987 Ummm... what?

There are geared transmissions for bikes but definitely not a build at home sort of thing and the ones sold are designed to work with chain or belt

Just genious! Depends on the outcome is better than bikes of nowadays. For instance I have been using inner tubeless tires for over 7 years now and just had to change them now. They don’t get punctured and are just a bit less confortable in terms of absorving impact when wheels get out of the ground. Obviously competition cyclists will have a problem with it. Since my purpose is having a cheap and exercising transportation, my chinese brandless bike does the job perfectly! I get to work and return everyday about 14km daily, not much but the bike holds itself steady and robust with 1 maintenance yearly. Would also change the system for this one if it was readily available. But I wouldn’t be doing the handyman’s work because I have no talent so just pay a specialist and done!
