Here a diagram:

- First gear will be on the right side of the wheel using a freewheel 44T sprocket (SBP has the freewheel adapter and sprocket), maybe a 48T if 44 is too small.
- Second gear will be on the left side of the wheel using a regular 40T sprocket.
- Centrifugal clutch will be as before on the shaft and will act as "freewheel" when on first speed.
- I'll use bike chains well lubricated and avoiding tensors as much as I can.
- Longer shaft will be hold on the right side with a jackshaft bearing to keep it in place.
absolutely, "first" gear needs freeweel, I got a 48T sprocket with freewheel from SBP, just trying to get some free time to put everything together...would the right-side gear need to be freewheel for when the clutch engages, jackshaft starts spinning even more rpms so not to be bogged by the right-side?
Thank you for the videos and the ideas! my OCC does not have gears itself and adding them is not cheap... but I like your idea!This is how I got around the automatic transmission requirements here in Tennessee.
One could also use a Kilduff auto shifter or modify a LandRider auto shifter to shift internal geared hubs as well.
