- Continuous variable transmission gear made of LEGO parts. Step by step from idea to real working CVT. Used in simple roundabout. This is most simple CVT made of LEGO parts. No slipping machine, high friction. Educational video to explain principles of CVT, how it works. The original idea of ball based CVT was invented by Leonardo Da Vinci and simmilar design from lego bricks was presented by Lego Technic Mastery channel. But there was no explanation of basic principles of this awesome mechanism.
Great video! Can we showcase some of your work on our Facebook page with credit to you?
Figures the only CVT designer to say "let's make it more robust" is building with Legos.
Why isn't this video more popular? This is really high quality stuff
Fun fact: they used to use a transmission in F1 that also had these
Is this what the inside of a Nissan looks like
I have had a Nuvinci CVT bike hub for years now, and this is the first time I actually understand how it works. I knew it had balls and they somehow manipulated the transmission, but I needed to see this vid to finally put things together in my brain. Thank you so much for this highly educational video!
insanely underrated😲
Really would like to see how it performs when force is applied to it. Like on a car. Great design, also can be controlled by a servo
Never seen a cvt like this before, usally it's the belt and cone ones
This is actually incredible!
A new easily broken CVT???
I love the fact that there are no limits for what we can make with legos
It took a brilliant mind to figure that out

This is incredible! It’s so much simpler and smaller than all other Lego cvt’s ive seen before
I didn't know CVTs existed until now, but now I totally understand them!
This is actually a wonderful transmission for low rpm engines, like steam; it's interesting that you used a variable flywheel for it.
Awesome explanation as well as demonstration. When i first saw this kind of CVT i didn´t understand it but the way you showed the mechanism it is now clear.
You need to make the CVT Foley automatic by adding a differential on the input shaft with a linkage connecting it to the control rod of the CVT so when there’s more load it all down shift and use a rubber bands to apply tension towards the high-speed side of the lever. Also put a small lever on the rubber band to add more and less tension for high speed gear and low speed gear!!!
This is the best CVT design I have seen. It looks really efficient and probably could handle a good amount of torque with the right materials.
