@deaftodd If you're still looking for a better CVT, just finished designing mine. It is not a variation of anything that is out there. Built mine from scratch without drawing on any previous designs. Compare this nuvinci to the cvt on an old snapper lawn mover from 30 years ago. Worst drawback is the torque limitation followed by the speedy wear of parts from slippage. That's why they put it on a bicycle. It's fine for that. Mine will not slip. Contact Gene waymaster@gmail.com

@YourFatClownAss Forgot to mention its bad efficiency as well.

@popnstart It's too heavy and has a fairly limited gears range for it's size. Nothing can beat the damn old school mech.

They must be the greatest thing for bikes since pneumatic tires IF and ONLY IF the Tour de France riders have them on their bikes. IMO.

@deaftodd Thanks Todd ! I might ask the guys from Nuvinci.

@hoverpal it's nuvinci cvt i think. a friend of mine actually held one. we both design electric cars and we rather keep on looking for a better cvt. he didnt say how much they weigh, tho.

@picmario And by the way, you will not get that thing rev so much faster than your input rev speed (don´t know the max gearing factor, maybe best to see NUVINCI´s website) for the gearing factor is limited, it is a CVT and not a IVT !!

@deaftodd
Who as build one of that size (do you remember his name?) and how heavy was it ???

@picmario Thanks for reminding, I am actually engineer ;) !
But if you consider an application where you put that amount of power @ the same torque output, can you imagine the forces that will appear when the moving components will rev at these high speeds ??
I doubt if the bearings of that small bike gear application will be able to cope with these..

Someone actually held one and they were too heavy
