Well, for all my aesthetic complaints about pinion styled gear boxes, this guy does this amazing thing- and it looks GREAT! Love this about bikes, the quick and dirty innovation.

[@EricPeelMusic]

Awesome! It definitely inspires me to get a mill and build one from scratch myself.

[@felipericketts]

That was awesome! Building things is so much fun. I have built a 17' skin on frame kayak. I experienced some setbacks through the process, but ultimately enjoyed it and had such a great feeling of having been able to bring the project to a successful conclusion. It turned out to be a beautiful object as well. Thanks for sharing this great story. Love the beautiful way your videos are put together!

[@relativityboy]

So fun! Thanks for sharing! FYI, your vids caused me to buy my 1st hub geared bicycle!

[@Cyclingabout]

That's awesome! 🤘🏼

[@iamiyo]

This would be amazing when paired with a Rohloff. Especially if it can broaden the range in the low end for extreme uphill terrain, and in the high end for those long smooth flats with a helpful tailwind.

[@seitenryu6844]

Internal gears generally have an input ratio limit, that if you exceed will invalidate your warranty and potentially damage it. You can always run larger gearing, and that's when the extra gears may have an advantage. If they were spaced similarly to the Speedhub gears, that would net you 2 more gears.

[@iamiyo]

@@seitenryu6844 indeed, we must take care not to overload the Speedhub, while maintaining the tandem/+100kilo rider transmission factor of 2.5. One more lower and one more higher gear would be a treat. 😀

[@White_Night_Demon]

oooh those look interesting, how much would they cost to make?

[@Dave5843-d9m]

Rholoff already has more than enough range between 1st and 14th gear - at least for a solo bike. Shimano has a gearbox with two derailleur blocks mounted opposite and a chain linking them. The selector shifts the chain across the sprocket blocks.

[@angelinof1804]

Shimano is going to do a similar concept gearbox, anyway you have done a great job!

[@Metal-Possum]

Shimano have only filed a patent as of yet. That doesn't mean a whole lot other than 1. they had an idea they wanted to protect or 2. they didn't want anybody else to have the same idea without them getting a cut of the profits. It's standard business practice to patent these things, especially if you're trying to protect your income streams.

[@angelinof1804]

@@Metal-Possum I do agree with you. Anyway this is more then an idea, this is a project, a big one, with more ideas inside . If they want protect themselves from the competitors, this means they know , or they cannot exclude, something can happen on bicycle transmissions..

[@naitsirhcalarap]

It is nice to the eyes . But the sprocket gear n plate ratio is still d same.

[@user-yv2cz8oj1k]

It is standard business practice, but if someone can prove prior art with something like this then the Shimano patent will then be worthless and then hopefully anyone can manufacture one. :D

[@markmoreno7295]

Actually, this helps me understand the Pinion gearbox better. While the Pinion does not use chains and is in an oil-bath it operates similarly. Strange that I always found the Sturmey-Archer complex, yet the one I have is just a three speed.

[@Shindinru]

Reminds me of the Phaser gear box (from ~2007-2009), it was also chain and sprocket based.

[@cristibaluta]

I like to build things that i'm actually going to use. Few years back i designed my own panniers for my racing bike, they are irregular in shape to cover as much space as possible, low gravity center, and i had a thin rear rack with a sliding mechanism, i slided some U shape parts with one channel on each side where a screw mounted on the pannier was sliding into. Today i changed the bike and rack and i'm trying to figure out a different mounting mechanism. Before this bags i was travelling with a backpack, it was horrible.

[@Rippthrough]

Bronze to stop it rusting? When everything else is steel? I would think that's for a much simpler reason, it stops cold welding when it's sliding between steel gears, same reason brass is used for synchros and dog rings in normal gearbox?

[@Cyclingabout]

You're likely right! That bit might have been lost in translation.

[@Sekir80]

Cold welding? I heard this term but it's space related, definitely not happening here. What do you mean then?

[@Rippthrough]

@@Sekir80 No, cold welding is not space related, cold welding is another name for galling - it's welding at a microscopic level between similar materials under pressure, which causes sticking, wear and erosion damage.

[@Dave5843-d9m]

Have you seen the Hossack bike that has full suspension and hub centre steering. Then there’s the Alan Millyard mountain bike with front mounted hub and drive chain fully enclosed in the single ride swing arm.

[@RubenKelevra]

Wondering if a regular full 21 gear chain gearbox could be fit inside a box. I think the only thing necessary to modify would be to allow the front sprockets to move right and left on the axle to avoid having too much side-pressure on the chain due to the small distance between the front and back sprockets. And then just having a cardan to the wheel would be so nice when doing muddy terrain 😀

[@dyzoly]

I've been thinking of building a gearbox since I first saw the Honda DH gearbox bike.

[@tristanyseult]

Frazer Nash cars used a chain driven gear box in the early 1900's for their sprint cars , very fast gear changes

[@lucatarabinisolmi686]

Amazing work

[@anotheryoutuber_]

this reminds me of when i took the motor and transmission out of my first car and made it pedal powered. had to gut it and weld and machine a few bits but mostly just ran a mtb drive train in reverse for a real low gear so hills weren't so bad. let me understand how nice it was to have the wind moving around my body while riding to keep cool. 9 speed is really strong just ran through chains quicker than normal, ill do it again hopefully someday but instead of a direct drive ill do an electric hybrid of sorts and pedal to charge a battery and do solar on the roof and hood.

[@cristibaluta]

Let's be serious, you can't move a car by pedalling, unless it was the german Trabant.

[@anotheryoutuber_]

@@cristibaluta if you can push a car in neutral you can definitely pedal it with the benefit of gearing with even less effort, doesn't mean its not alot of work and its not breaking any land speed records for sure but with a gutted car with no motor and transmission there is a long list of cars you can pedal. "cant move a car by pedaling" i have.

[@White_Night_Demon]

@@anotheryoutuber_ must have been a small car then. no way you can pedal like a say a huge 4x4 truck.

[@anotheryoutuber_]

@@White_Night_Demon it was an 88 Corolla wagon. Plus a bike drivetrain weighs less than a cars, it's a benefit of the swap.

[@White_Night_Demon]

@@anotheryoutuber_ so you took out the engine, the gearbox, differential, rear axle and drive train to replace with bike pedals (which you'd have to make a hole on the floorboard on the driver side), a long ass chain, some sprocket gears, derailer and solid rear axles? Was this because the engine died and it was too expensive to replace and cheaper to just take it all out and make your own pedal powered car or was it just an experiment and felt like doing it at the time?

[@pashakdescilly7517]

If there were two selectable chains on the second 'return' drive, this project would become a six-speed, much more useful. It would need to have a wide gap between ratios on the second stage, and the selector on the upper shaft. You might be interested in the race mountainbike built by Allen Millyard a few yeers ago and raced successfully by his son. It has a hub gear mounted above the bottom bracket, driven by an enclosed chain, and another chain inside the rear suspension arm (one arm, not a fork). It's all enclosed, and has very low unsprung weight, and allows easy removal of the wheel - not that this is going to be needed much, as tyre and tubes can be changed without removing the wheel. Also, Mike Burrows came up with a concept for an enclosed derailleur system for commuter bikes. It would have worked well, but no-one made the 3-pulley rear derailleur needed to make it functional

[@mavver]

would you make video about effigear?

[@heroziolkowskimendoza9800]

such a handyman, amazing

[@tobins6800]

The only difference between this and a Harley Davidson gearbox is the opposing gear engagement. Chain vs gear mesh. Acetone and shavings from excess material would make a seamless bond and also up the whole thing to a new level.

[@pashakdescilly7517]

The bicycle gearbox illustrated in the video lacks the ability to disengage the three internal reduction chains and lock the input shaft to the concentric output shaft. That would of course be direct drive. This is the classic gearbox layout used on most European and American classic bikes, and Harley Davidsons to the present day. The Zundapp K500 flat twin and K800 flat four motorcycles of the 1930s had a four speed chain drive gearbox and shaft final drive

[@madmadimadison7542]

Has anyone built a CVT for a bike yet? Would it be viable? I mean in a gearbox, not like the Enviolo nuvinci cvp hub.

[@user-yv2cz8oj1k]

You tend to have a lot of power loss on a PVT, so in cars they only used them on larger engines. There is the enviolo rear hub that is PVT in a rear gear hub, and though slightly better it still suffers from more power loss than a planetary gear hub like the more popular Sturmey Archer, Shimano Alfine/Nexus, or Rohloff.

[@madmadimadison7542]

@@user-yv2cz8oj1k Thanks L, I think you'll find that there are a few small cars that have CVT's though, Renault springs to mind. But Europe is often a different planet to many mechanics, lol

[@josh573a]

i wonder if something like this could allow a super high power middrive to have a long lasting gearbox...

[@geemy9675]

yeah several companies are working on it. nor necessarily "super high power'' but combining mid drive with a reliable gearbox would be great for MTB/touring. revonte one has interesting approach with eCVT design coming from the automotive world (hybrid eCVT like Toyota/ford...) and can make 2kW and 200Nm of torque. I don't think it's worth designing an engine with much more power than that. once you reach certain power, with the battery and controller to power it, a heavy duty chain, it becomes so heavy, hard to pedal and powerful that your own pedalling power is useless. if pedals are just a way to control the motor power, you might as well use a throttle, foot pegs, throw away the pedals, the gearing, and just use a much simpler and more reliable single speed mid motor like on the Sur Ron, and call it a motorcycle. a sur ron with pedals is stupid

[@White_Night_Demon]

looks neat, I want one too! Looks like I need over $10k for the parts, materials, tools and equipment to make one....

[@Metal-Possum]

A suggestion for improvement, single speed chains and sprockets. :)

[@pashakdescilly7517]

Being enclosed and running in clean oil, it's not going to wear out.

[@user-yv2cz8oj1k]

@@pashakdescilly7517 the idea is to not run it in an oil bath, as that's a significant amount of extra weight to drag around.

[@tomekvilmovskiy6547]

guess, the gearbox was built just for fun, as well as the whole bike. obviously, the cheapest shimano nexus-3 will last longer. )

[@snowflakemelter1172]

As an engineer every time is see an exposed chain drive and derailleurs I weep, a sealed gearbox should have been standard decades ago.

[@ParaBellum2024]

Derailleurs do work well, though, plus they offer advantages such wide gear ratios with light weight, and they last. I bought my bike in 2004 and commute a few miles most days. The derailleurs require occasional cleaning, lubrication and adjustment, but no more than other engineered solutions. To achieve the range with sealed gears would add a lot of weight.

[@JDrwal2]

Why didn’t you start with saying that it has a whole 3 gears!

[@evrac1]

As a fellow gearbox aficionado, you might enjoy watching a video made of me presenting a project I did at my university. It's specific for high-pivot downhill mountain bikes. Sorry the video quality is bad, but it gets a bit better a few minutes in. Keep up the good work. Cheers, Stephen kzbin.info/www/bejne/rmqWo4aumJ2emsk

[@Cyclingabout]

You're next level, Stephen! I watched your whole presentation with the slides open in a separate window and loved every moment. It was cool to hear everything laid out in a chronological format, with the historical examples, pros/cons of the different designs, and your proposed solutions. I hope your gearbox design has moved forward in the years since. It turns out I'm also a high-pivot aficionado! I've spent a fair chunk of time on a Canfield Jedi and was pretty close to getting a Zerode G2 at one stage. If your bike works out to be somewhat similar to the 2022 Norco Range, you'd have a customer! On paper at least, the Range has my ideal suspension kinematics and geometry for the kind of terrain I like riding - the only thing missing is a gearbox. 😉

[@evrac1]

@@Cyclingabout Thanks very much. No, I'm sorry to say that it has gone no further. Basically I'd have to quit my job and go all-in on it, but the return on that investment is unlikely. DH has actually become a dwindling market. I'd love to redesign it for Enduro, and going to 9 or 12 gears. But the width goes up with the number of gears and the diameter goes up with the range, so to give viable ratios the whole thing becomes too big and heavy. There's also likely quite a bit of friction because of the rotating ring gears. I'm disappointed too, but trying to be realistic. Cheers.

[@Cyclingabout]

@@evrac1 I guess it really cannot get much bigger, or it compromises frame design too. All the best with whatever projects you're currently working on!

[@evrac1]

@@Cyclingabout I'm on a Zerode Katipo with a 9 speed pinion and belt drive now, and it's pretty amazing. If a company wanted to combine a high pivot with the pinion it could be easily enough done like the Deviate Guide. Now we just need Gates to make a belt long enough for this application.

Chain wear can be an issue

[@simonm1447]

If the casing is oil tight you could run the chains at least partially in oil. Since there's no dirt inside (what causes most of the chain wear on a conventional chain) it would still last quite long, even if the chains itself are very short.

[@JanTrenson]

Come on, Shimano, get to it!

[@varez93]

I have recently discovered a Korean start-up which is developing another bike gearbox with the aim of being cheaper and lighter than Pinion: kzbin.info/www/bejne/g5_Eq3ujaa9-oc0 I really hope that at some point we see other hubs/gearboxes on the market apart from Rohloff and Pinion, which unfortunately are out of budget for most mortals. Sure, you have the Nexus and Alfine hubs from Shimano, but they lack the low gearing which is required for touring or even commuting in hilly terrain. Something under 500€, with at least 7-8 gears and the ability to have really low gears (which again is not possible with the Nexus/Alfine hubs) would really make IMHO derrailleurs obsolete except for ambitious MTB and road cycling.

[@Cyclingabout]

I saw that video a few months ago too! I might get in contact with them to find out a bit more info. It would be incredible to have some lower priced gearbox bikes on the market.

@@pcdispatch Yes, I forgot to mention Kindernay. Nevertheless, it has the same "issue" as Rohloff and Pinion: Price is too high to make an impact on the bike market, it will only be a niche product.

Stupid thing is that 1 planet, sun and ring gear can give you 7 speeds with whatever range up to 10000 percent between low and high as you want. At much better efficiency than anything else around. And the opportunity to split input with pedals and motor generator. Which actually gives an infinitely variable transmission. But no-ones bothered to do it. Why the f did this guy add the superfluous extra chain to take the final drive back to concentric with the BB. Stupid extra complexity, and waste of opportunity to raise it to where it can work properly with suspension.
