So I saw this CVT video on Youtube, and the guy has a really large sprocket on the motored side, looks to be attached to a disk mount. YouTube - MoToRiZeD BiCyCLe - CVT+HoNDa GX35 My question is this. Where in the world can I find a sprocket this big, and what kind of chain do you think they are running? Anybody know what they got this sprocket off of? I figure with a sprocket that large, a jackshaft won't be needed using a Pocketbike CVT on a motorized bicycle. Goped sprockets with tiny #25H chain goes up to a 98 tooth. Can anyone help with this? I'm tired of my scrubber drive on my bike and not being able to climb big hills like I can do easily with my CVT gopeds. I live in a very hilly area, so I need to find this. Thanks!!!! Oh, and here's my CVT goped.
