I'm new to this site but wanted to show my own use of the pocket bike cvt on my mountian bike. Here is the setup:
Zenoah 51cc engine (peak power 3.2HP @ 9000rpm)
Pocket Bike CVT with 11 tooth pinion sprocket for BF05T 8mm chain
72 tooth BF05T 8mm chain sprocket mounted on a freewheel
Back when Staton-Inc still carried the CVT, they said it had 1.9:1 to 1:1.1 variability in the belt/pulley system, multiplied by the 3.714:1 gearbox. I've measured the diameters that the belt rides on the pulley and took apart the gearbox and counted the teeth and got about the same numbers.
It rides great and will pull me up any hill. Takes off good from a stop and accelerates quickly. I don't know the top speed, but it's about as fast as I want to go.
