I've seen this idea before. Problems are 1) gear ratio, you're confined to one, 2) the actual contact point and transmission of power is confined to a single tooth at a time thereby putting extreme force onto a small point, 3) the drive shaft roller bearings are pretty small and likely to fail quickly, 4) the drive shaft is thin and subject to distortion.

Wow look now we’re pedaling twice as hard for what a chain can do in one pedal 😱 10/10
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.

Lovely design, and it's quite therapeutic seeing the stages of the build. It's no doubt less efficient than a chain though. I think having a one drive set up like that would suit an E bike more connected to a tidy throttle.

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.

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...?
One thing i would've added is a banding that went over the sprocket's retaining pin, with a single, light tack to keep it in place. I've used the 1800's variant of this bike and that's one of the biggest issues with this design, the pin coming out after a while. Could also be fixed with making a longer pin, that has a hole, for safety wire, which was the way they did it (on the restored bike i used) but the problem with that is, it can catch clothes, so a sleeve would be more "permanent" and clean.
Too much criticism from people who couldn't pump up a tire without botching it. Great craftsmanship!
Just what I was thinking!
I love how this “prototype” has been around since the late 1800’s
And was soon abandoned.

This's cool DIY video, but shaft-driven bicycles are already there for more than 100 years, since 1890. Actually, chain-driven are considered a vast improvement over shaft-driven bicycles with better performance, efficiency, and ease of maintenance.
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.
I think this is slick! Probably an issue if you get dirt/pebbles in the gears though.
Awesome! And to make it even more useful, install a 3 or 5 speed internal rear hub, then you have gearing options without derailleur gears and chain to worry about.
The sleek look is definitely top notch. The major disadvantage is friction loss which will be much higher than a conventional chain.
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.
Nothing like re-inventing the wheel. A pal of mine has an 1898 Belgian FN, which I've ridden. Nothing new here, but I admire your hack it and weld outlook.

This reminds me of those ideas I had when I was a kid and how genius it was. Only to discover someone already made it years ago. This gives me same vibe.
The major issue with his sprocket build is that he was to pedal extremely fast for minimal energy transfer. In other words his system is far less effective than a traditional chain gear system

I think you mean "wheel-less"
Back around 1899 to 1910 a luxurious expensive bicycle was made with a drive shaft that surrounded the right chain stay and had bevel gears on either end. This was an alternative to a chain.
Cool concept. In the early days they could not manufacture bicycle chains, so all biles were chainless, some with shaft and bevel gears. Question is if it can handle the torque that is as great as in a car engine, around 100-180Nm dependimg on how strong the biker is.

Very cool. I like the thought. One difference I’d probably make is to find a larger diameter bevel gear for the pedal shaft. Seems like it requires a lot of pedal work for a little amount of output at the moment.
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
I have a new bicycle from 1983 that has front wheel drive with this setup and also has a cost gear where it lets it go fast down hills and not eat the gears out while peddling with chain on back, 10 speed I think. Bought it from the man who put it together in 1983 and still has tips on the tires. Bought it because it was different, No one ever ask to ride it so it just hangs around
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

Не ну это конечно вообще законно?! Как я раньше жил без этого?!!)))
The power loss from the pedals to the rear wheel is insane.
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.

Nice job! It is a work of art. The reason they don't make bikes like this is that steel is stronger in the pulling direction that the twisting direction. The shaft will always be at least as heavy as the chain. Also bevel gears are less efficient than roller chain, and tend to slip more.
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. 🤣👍
I never experience chain breaks . Chains are by far more efficient in power transfer than shafts
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 🤣

Bud Shaft drives have been around for a long time, I've seen Bike Share bikes in Hamilton, ON with them before you even made this video, they're popular on Motorcycles too
Smart, as idea... but it has mainly two defects: - the hub of the pedals is blocked, it always turns. - only one transmission ratio is possible (and, in this case, too short). Anyway, again... nice idea, nicely performed; mostly for the cheap (using parts of old drills) and quick (entirely handmade) kind of solution.
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.

Looks like the gearing ratios may not have been taken into account. However this is still a great foundation to build from. Good idea.
That would be tough in a bicycle form factor. Motorcycles have a fairly wide transmission that wouldn't easily fit into a bicycle. You could probably do something along the lines of a continuously variable transmission though as that doesn't require much space to work with.
That'd be great if you could engage/disengage it. Then it could b used in case your chain breaks as a back up. It might be useful for motorized bicycles too.
The part I like the most is going downhill free wheel with that bike. That pleasant vibration of 3000rpm spinning pedals feels like you're riding a thresher.

I have not seen it on a bicycle before, so that was fun 👏 It would be okay around flat, Flemish countries, since there are no gears. I noticed there is no retaining part, to hold in the modified - 'cotter pin', so it's just relying on compression, but that is an easy fix. Sometimes we have to go back, to go forwards... ie. A Hybrid engine originates over 100 years ago - from a submarine and the electric car was first developed in 1890, before the combustion engine, yet its become the 'new' thing... Good video, thanks for sharing, Atb Gus 👍
Back in these days there were only shaft bikes, no chain it wasn't invented yet
@@MainInternetUser No. Just no.
Shafts suck for this application. They're acceptable for motorcycles because you can build an engine that can provide enough power to make up for it, but they just suck. If you're concerned with maintenance the best compromise would be a modern belt driven bike. They're slightly less efficient than a standard chain bike, but they're much lower in maintenance. But, really, chain maintenance isn't that big of a deal.
@@SmallSpoonBrigade you make a valid point. There is another way... The future is 'frictionless', so no 'gears' - no 'real' maintenance needed 😉
Yup. It was billed as "ideal for the ladies" because there was no chain to catch/dirty your clothing on.
Amazing.... the first patent for one of these was granted in 1891.
Very cool!
You should be very proud of yourself....it has problems such as wear, gearing etc, but you got it running! Well done.
Improvements: Use ballbearings to reduce friction Make a more sturdy connection Make a gearbox Use screws with loctite to secure gears
Actually, with this design, you shouldn't use ball bearings, but rather the same kind of bearings you find in automotive differentials, as they're cylindrical, rather than spherical. While they have a wider cross-section, they offer more stability to a linear rotating system.
@@isaiahwelch8066 true
Loctite
Wow! Creating a prototype of exactly what is available in a production bike. That's insane!
The gear shaft bicycle concept has been around since the turn of the 19th century into the 20th. The gear shaft eliminated the 'dead space' of the chain bicycle of the pedals at the 12 o clock and 6 o clock position. That said, the gear shaft was reputedly harder to pedal, took more effort, and presented its own set of mechanical issues. The gear shaft bicycle concept refuses to die and lingers around but it will never supersede the chain bicycle.
Congratulations! Now You can ride the cycle back and forth. 😍
Идея интересная, но на мой взгляд, надо на валу храповый механизм установить для свободного хода колеса.
Не надо так сзади есть барабан который и так эту функцию выполняет
@@rompure2795 Зря Вы разрушаете этим людям иллюзии. Они достойны друг друга, один думает, что сделал прорыв в велостроении, другой даёт советы как говорили в фильме Собачье сердце "космического масштаба и космической же глупости".
Так то не плохо, но потерь вагон, два редуктора ведь, придётся быстро педали крутить и тихо ехать
The gear nearest the pedal needs a guard over it to prevent things from getting between the mesh of the pedal gear and the drive gear. Dirt, debris, loose clothing and other things could get caught between the 2 damaging the gears.
Во первых такой велосипед уже создавала какаято маститая фирма, во вторых было бы неплохо к этому делу притаранить гидромеханическое автоматическое сцепление рекуператор.
but it will be alot better if you make bigger circle at front for speed and a little cover for safety
Nice craftsmanship, but an open bevel gear is a short lived beast.
Ya know, there's a reason that bicycles evolved with a chain drive.
Sou fã dos trabalhos desse gênio The Q! 🤣👍👏👏👏
Not a bad idea, but the gears ought to be greased to protect them from wear. Also, having an enclosure around the gears to prevent sand, rocks, etc from getting into them would be smart
Lol. The minus of this mechanisms is that if you let it go , the pedal will continue spinning bc it directly connected to the wheel. lmao. Fun trying to catch up with them
Shaft driven bikes are immensely troublesome. Chain drives are far superior and vastly more rugged. The shaft drives are outdated and always tend to fail due to the prying nature of the gears. Even with shaft bearings they are no comparison to the chain drive
Yep. There’s a good reason for chain drive being the universal mechanism for pushbikes. This is a bit like making a piston engined airliner.
100%
shaft are also not that efficient when deliverinv power to the wheels compared to chains
@@tjfSIM or eating instant coffee without a spoon.
Not to mention that you are stuck with one gear.
Нужно постоянно смазывать шестерни, чтобы не износились. А педали нужно крутить в 5 раз больше чтобы скорость была как с цепью. Интересная концепция, но утопичная, на мой взгляд
Да я бы сказал вообще хрень полная
А кто не даёт планетарную втулку поставить вот тебе и скоростя, также сделай кожух чтобы шестерни не торчали
Но мне цепь больше нравится))
@@mikhailsabaleta7902 так этот хрен не поставил. Видать ему и так удобно
Ещё постоянно нужно педали крутить, особенно при спуске , а то ноги могут пострадать.
Yeah,. Keep grinding don't stop
I really love this. If you sell it, I wanna to buy this so much.
