Guys- it looks like the whole thing swings on that pivot pin below, as it is pulled by a lever and the swinging action does the ratio changes as each belt get re-positioned on the sheaves.
So this system would require a clutch / idler to tighten the first belt off the engine, then a gear selector lever to swing the varidrive and change ratios.
I have an in-expensive lawn tractor with this system and I like it.
With the clutch depressed, the primary drive belt is loose (you are at a standstill) and as you let it out- it engages and all the way out the vari-drive goes into hi ratio.
Push down some and the tractor slows as long as you hold down the petal at that position.
I am sure this could be adapted to a bike but it would need a separate clutch lever and ratio selector.
