- The WaveTrans is a new kind of Bicycle Transmission that uses a revolutionary logic/design.
You can change gears with a press of a button. It has six speeds.
It's controlled by a microprocessor and a PLC which makes gear shifting really smooth and easy.
The prototype presented here is a proof of concept.

I'm so happy to find this vid because I thought I was the only person who had this idea
I had the same situation too 😅
@@gustavgnoettgen So does about a billion people in China!
@@bq1000bq?
Same for me
No you're not the only one, I find here too with same idea!
This is truly an ingenious invention, that could change the way we achieve gear ratios on a bicycle! I love it. That's a very impressive design you've come up with!
Овчинка выделки не стоит. Русская поговорка.
I had this in my thoughts too. One chain ring does it all. Thanks for this video. Brilliant creation, much better than the shaft design.
Cutting edge 80's music!
Which cyclist hasn't had this idea? But it takes engineering prowess to actually bring it to fruition. Hat off!
the transition looks really smooth
I could see this working with a ~12t - 14t small cog coupled with divided cable grip shift. Design the chain ring to expand only after smallest cog engagement. Need to make it work with cables though, not a computer.
There is one startup that is iTorque. Check it in LinkedIn. They are claiming that they made the design similar to it with pure mechanical mechanism
The music is fitting for when I first saw a pure mechanical version of this in the mid 1980s.
It didn't sell well because it was prone to mechanical failures: too many small parts could not withstand the big forces on the gear blades.
I wonder how modern materials cope with these forces.
The whole design is unbelievable. They have created something that is exciting and compelling.
John Gault perfect chainline is advantage
Zero advantage? Front gears that don’t change the chain line at all???
imagine what a belt drive system combined with this idea would look like.
The BBC's Tomorrow's world featured this concept in the late 70's / early 80's it used Pistons mounted on springs. As load increased the springs compressed reducing the chain ring diameter, as torque reduced the springs pushed the Pistons out. It was a bit clunky though.
I have invented the same thing! Great to see somebody else actually making it work :))

I tried it few years back(not electric) and it turned out to be a vibrating machine rather than an innovative machine that could beat filthy gear shifters!
Not offending you! You are good to go as long it elimates vibration and give a smooth( our motive, i guess) ride.
Very cool concept. Patent pending is encouraging. Looking forward to production pieces and pricing. This type of drive would eliminate that damnable rear derailer.
I love this idea. I have a full suspension mb that I really like and have set up for my liking. This would be perfect because I can keep my mag wheels that I like. I need this!
I was on my way to the patent office when I thought I should do a self check on similar work. 🤣
Nice concept, been dreaming of such a device for a while ..well done chaps..
I have no idea how this thing works. I don't even know if it has a derailleur. The video needs some text or narration.
The whole design is unbelievable
congrats guys ,this is so kick ass i want one when they become available
Curt Keeler maybe not yet affordable for me though when it starts selling.. Huhu
This variable chainring design was published in bike magazines in the mid 1980's
Very happy with. Worked as well as i expected
Very creative, many thanks for uploading, 🌹 hopefully it is reliable as well
New era of bike shifting
wow I had the vision while ago while climbing the hill. This is amazing and will solve the bad transition between small/big chain ring issue. Good luck and hope to see this in production soon.

I had the same idea recently while in bed just resting.
@Jack Ophelott High on life, actually
So ironic, I knew someone else must have had this EXACT idea before me :D Nice work guys, you beat me to the execution!
What I want to know now is will this stand up to mountain bike use?

Continuous change of speed without lost transmission. Wow
You are a genius.
Seriphim avatar nice ;)
@@MichaelHenderson59
Yep. Seraphim logo. The best IA of a RTS game.
Beautiful music. Good technology.
These guys have the holy grial in their hands....
stingray565 I would not bet on this.
the mechanism is awesome, but it would be a royal pain to maintain it on a bicycle.
When I think of the future of bike shifting I envision this. Couple this with a rear WT gear set and the possibilities are limitless. Curious how each "finger" would hold up to high torque demands.
nice design .keep us posted on future production
I want to make one of these! Why does every modern bike not have one? Seems quite a simple and single unit that could handle most gears. No need for rear gears or any chain line deviation at all..
I feel like it'd come down to it not being easy to manufacture and most people don't even know how a traditional derailleur works in the first place. Plus it seems like one of these would be pretty expensive to maintain.
Looks to be something that could easily be knocked out of alignment or damaged if the bike falls or hits up against something. Also will be very expensive. There are much better alternatives. Also, as the "cogs" expand, how do you keep the chain from jumping teeth? You can even see the chain slacking in spots when pausing the video.
You can see in the video the fins move one-by-one in the part of the rotation where there is no chain on them. It cannot expand under the chain.
whats with all the B-roll ? is this about a transmission or cinematography???
love it...stick it on the rear wheel (eliminating multiple casettes/limited selection) and when you/they can make it both durable and lighter than the current dura race it'll be the future.
anthony wallace you dont need multiple casettes in the back... This is a 6gear bike... If they make more stages, it will be even better
This is Awesome..good work man..will this work for a belt drive? Even go Auto someday? Thanks & keep up the good work 💕
Просто и гениально!
Great invention. Would love to have this on my bike.
But personally I'd prefer manual/mechanical transmission (no batteries). I bet it would lower the price of the product and made it more available.
That was invented in the mid 90's the Auto Bike, it was not very popular because cycling at that time was kind of in the back burner with the take off in mountain biking.
I thought the same thing but if they could make this within the price range of other e-shifters it would still be viable.
@@eyeofhoruswadjet4236 only issue I see with no battery option is it would be hard and even more complicated to sequentially engage all of the "fin gears" idk what to call them but if you look at the video you can see it engages in a sort of wave one step per rotation it. You would either need an overcomplicate and more than likely heavier than the electric solution. Or run it centrifugally, but this would almost 100% be constantly unbalanced and thus a vibration magnet.
This pretty interesting that I found this video. I was watching informative videos about CVT transmissions and figured, "Perhaps this could be a great application for a bike!" I love your video and invention. Have you gotten this prototype patented?
Patent has been filed.

Please can you make a explaining video of the mechanism..
You are great man, keep up the good work 👍
Amazing new 🚴 bike
Interesting prototype, what is the wheight? Could this be linked with the powemeter so you stablished some power and this will adjust acording to the power you select?
+Afonso Ramos First is obviously going to be a few garms higher. The second is only a software problem.. This however is just a scientific demo.
+rkan2 how many is "few grams"?
Yes, if I add two more sensors and rewrite the program. There are more answers here www.wavetransmission.com/faq/
Looks promicing but the gear ratio looks a bit tall to start with, I assume due to the mechanical limits in size of the actual mechanism which could work for road.
Obviously the other concerns is weight and cost. Chain rings traditionally are a part that wears over time also. The actual gear teeth would need to be replacable and that is another cost concern.
Cool concept.
"The actual gear teeth" part will cost around $8. Takes teen minutes to change it.
Could you achieve smooth, even run? How many gears are in situ possible?, especially in smaller gears?
There is one startup that is iTorque. Check it in LinkedIn. They are claiming that they made the design similar to it with pure mechanical mechanism
You can't actually see the thing so i find this presentation annoying.
Very clever. It should be nearly as efficient as singlespeed (97% @200 watts) and better than rohloff (94.5% @200 watts).
I guess it will slow down as you pedal hard bcoz the pedal gear will be push down so it became a smaller sprocket...so I guess the sprocket size in the back wheel should be change to a bigger one....the bigger the faster!
it`s just beautiful...
Thanks.
pas d explications donc bof bof bof
i think this is an awesome and cool invention and i hope you have the best of luck of it coming in production 👍
Thank you.
WAVETRANS I'm a lol jealous of this fine piece of innovation as I was working on this concept for a motorcycle sprocket system back in 2011. But your managed to put together a working prototype and everything! High five and great work. Would you be interested In helping me develope a system for my motorcycle, being as how youv figured it out? It would be much appreciated
Good n interesting invention.. good luck guys.. 🖒
This design could only change gear slowly and gradually. It can not jump from high gear to low, or the other way around.
Great Invention
That's pretty dope man :)
The solution of never existed problem .
Here we go: what about making a stretchable chain that eliminates the rear derailleur? If the chain was redesigned with a wide small-toothed belt made of interlocked magnetic or spring loaded plates, it might work without the teeth misaligning. I'm not a physicist or an engineer but seeing this incredible and inspirational invention made me think of ways to incorporate Wavetrains without the rear derailleur. Amazing stuff, by the way
The back derailleur already eliminated.
What about back wheel? The same system? But with inverting function.
I just searched youtube to see if anyone had done this allready...
My question now is - is this or any similar product available to buy? I would want one for my MTB.
very good 👍
It was exactly I wanted
Well, the demand is here. All you need to do is find a manufacturer, created ads, take orders, and make money.
Ingenious but quite overcomplicated tbh
How durable that is? Does it work on when there is dirt, water, snow, ice?
So trippy
I HAVE A QUESTION:
why has it not become popular after two years and has not yet appeared on bikes? It is a great idea so I don't understandand
Have you heard about the two guys who invented the barcode? They could not sell the idea for more than 10 years, eventually they sold it for a relatively low price. Later it become a huge success. You can have the best invention on the earth, but there is no guarantee that it will make it right away.
WAVETRANS
Thanks for the anwer.
I agree with your comment and i wish you goog luck.
(Sorry for my bad english)
I hate it when I shift down and it won't go in gear. Then I get to the top and I can't get back in top gear! Now we just need comfortable seats
There goes my chance at fortune and fame. I had a similar idea. So with everybody thinking it, why hasn't big bike makers utilized this?
Vibration issues lead to poor efficiency, so it was abandoned.
Nice.
technology wise is good. but whats the difference if you still have to press a button to change the size? its it still the same as conventional way. if cvt it sense the load and changes ratio automatically referring to load
Just two extra sensors and rewrite the software, that's it. Can be optional.
WAVETRANS if thats the way, TREMENDOUSLY BRILLIANT! Just like the old days, i always dreamt of cycling without changing the gears. KEEP ON THE GOOD WORK MY FRIEND.
Music sounds like fucking Half Life 2.
Oi amigo
Você vende um desses?
I see similar thing in my mind.
No issues with assembly for me ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
Where are the batteries and motors?
i like it !!!
It's 8 years later in 2024. Has it been commercialized? How many has been sold?
Looks like Arizona.
Unfortunately it looks to have a very limited gear range.
Hello! Can you help me make one for my motorcycle?
I have no idea how this works. I never saw it shift once. You need some voiceover to explain. You need some superimposed arrows to point out the shifts.
Look at the gear. It expands and contracts.
cool...
Can you use this to an ebike ? Is it for sale ?
Very interesting - but how strong and durable is it?
+BannorPhil That will get destroyed as soon as water hits it as it's just a demo...
Its a "no no no" for me
It is intelligent innovation but doesnt look that smooth we expected
Dude do you know what is CVT ? It changes ratios Naturally depending on the loads its just CT not cvt
Huzaifa Khan to be fair it is a very similar concept
i thought cvt meant having infinite options for ratios. TIL
awsome... but will it cost the earth .?
I really don't need another flaming battery killing device or computer to change gears on my bicycle. Or a friggin' app system for changing bike gears with a cell phone.
How does it work? I hate videos where they Don't talk.
.....and how much is that gonna cost?
Automatic Transmission
progress? Kickstarter?
Electric shifting is super old
Tired of shifting those derailleurs, eh?😀
Drivetrain might be total crap - All I know is that I got really pumped by the soundtrack and scenery, lol.
I thought I'm the first thinking about this xD
Hello you.
This is not a cvt, the fact that it still have gear ratio makes it a not cvt system :/
