You wanted some feedback so here you go. For the overall design it looks great. I don't know a whole lot about CVTs but it appears that the actual CVT stage of it occurs after a relatively large reduction from the motor. This is good in the sense that the belt is moving slower but bad in the sense that its cones have more torque. Which means there will have to be more friction between the belt and the cones in order to prevent slipping.

In the gear reduction, why are some of the gears different widths? Also, why is the Chiaphua on a separate mount? Last, you don't really need a shaft coming off the Chiaphua. You can put a gear right on it and it will be fine, just like the team 716 2003 single speed gearbox.
