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.

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.

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.

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)

If you stopped pedalling once up to speed would the pedals still keep going round? Also if you pedaled backwards would you go backwards if you could balance?

Obviously with a bicycle gearing is a substantial consideration that favours chains. 👍

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.

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.

You just need a higher gear.

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.

@@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.

@bottomline99

@ 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.

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.

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.

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.

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

I was just thinking how I needed a bike that was harder to peddle and slower. KZread saves the day again.

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

It seems like you have to pedal 10 times more than you would do with a chain, just to gain a mere fraction of the momentum

Nicely done ✅ A good take on an old idea 💡 It's amazing to think they made this concept, back to 1898 with the Chainless Columbia Model 51, which was also shaft driven... 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...

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.

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!

They used to have an amazing bicycle museum in Chicago. It was so interesting to seen exotic old bikes, their design elements. So many of them had things that the modern bikes had, but sometimes different materials. So, the latest and greatest “advancement” were just rehashing or reinventing an idea that was tried in the past. The major technology that has made a big difference is carbon fiber, those early makers had nothing like it. However, some of the styling of carbon frames and components harkens back to bikes made of wood, bamboo ect. The shaft drive idea has not gone away and it may one day find a place, like the e-motorcycle industry. Major Taylor was a champion track rider that used shaft drive bikes with success. I own an antique Crescent shaft drive, very nicely made, but noisy.

how does freewheeling work and, also, how would you account for gearing? You could look at hooking up a nexus hub somewhere within all that I guess.

Orange clockwork with no gears. Now you have to reinvent 150 years of history to get gears!!

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.

There’s no way to change gear ratios so hills might be a challenge. Another potential problem would be contamination and grit sticking to the exposed gears, grinding away and making it harder to operate over time. You would be oiling it down every day. These are some reasons motorcycles use sealed shafts.

The wheel to pedals rotation ratio seems to be different in separate scenes which should not be possible and there's not a single scene showing actual start of movement by pedaling (he clearly pushes with left leg in that one scene) so I don't think the rear cog is even attached to hub (he just drops it in place and actually attaching rear cog to hub is never shown). I think this is not a working prototype but the bike is simply pushed to movement and he is just acting to pedal it forward. The scene with turning from left to right shows the bike to be very unstable which also suggests that he is not putting force to rear wheel but free rolling while acting to pedal.
