mini-CVT

flyweights.

i need something like this - what ratio is this working on?

Its a set of springloaded rollers on the inside of the pulleys set up in such a way as to push the pulley up or down when they are forced outward.

Sigh.

They don't change gears; that's the point.

obviously there are no actual gears. gearing is a generalized term irrespective of the use of actual tooth gears

They change ratio by use of roller-driven spring-loaded centrifugal pulleys. See how they're moving up and down here, changing the ratio?

yes I get that. I also get the claim that they are positioned by centrifugal wedging. I'm a little puzzled how they can move in such sync with such a crude system but be that as it may.
either way it's not relevant. electric motor with fixed gearing will rule. CVT need not apply

Doubt a CVT would work in an f250 pulling a load for 200k miles. More likely good in light weight / low mileage applications.
