nunbin total ungezogen heute wer will mit mir camn der kann sich ja melden

[DKINE59]

i wonder if this can be used on a unicycle....

[Hoobencan]

That sounds like crap, doesn't it ...

[MrCovertcat]

I think you're hearing the electric motor and all those gears on the left - I'm guessing that if something rolls like a bearing, it had better be quiet like a bearing too!

[Bush55555]

Awesome how it works :-O

[LetsWangChung]

what is it

[sgsawant]

It's a NuVinci Continuously Variable Transmission(CVT). Notice how, initially, the Red disc is spinning faster than the Blue disc ( 0:02 ). As the person makes the adjustment the Red disc progressively becomes slower as compared to the Blue disc ( 0:28 ).

freakin awsome. How can i get some specs so i can make one. email me please.

[shell3504]

really cool

[meandmyevo]

about how much torque are these CVTs rated for?

[pwjm]

its designed for bikes... soo not much.

AKAIK nobody has tried it on an e-bike application as of yet.

ok, since I posted this video I feel like I need to explain the fluid matter! It's a different story if you only have to make a ring turn with no resistance involved, or if you are planning on turning a whole wheel with it with the resistance of an uphil journey! So the Desktop Unit works without the fluid, purely because there is no ( or hardly any ) torque involved.

air itself is a fluid, and enough to provide some traction under high pressure. My guess is this showcase setup was machined a little differently to work fine without the high-density fluid. Am I giving them the benefit of the doubt? Yes, but it is very reasonable.

So much for its "special torque fluid" ;) Thanks for posting this video!
