Some ideas from GT bike
Frame mounted hub:
Check the GT dowhill bike frame mounted internal hub set up. One comment on this set up is that the hub is not touching the frame on the encased tubular section around it. That is done just for looks. The hub is suspended from the axel. The output sprocket from the hub is mounted where the disc would go, on the left side.
In our case with an engine with an output sprocket on the left side, we would have to mount the Staton double gear sprocket on the right side of the hub. The engine would still need a jack shaft to bring the power to the right side and work on some ratio reduction.
But the pedals would just fit exactly like on the GT.
An ideal candidate for the hub would be the either the dual drive hub(3gears 187% change) from Sram. It would require a fixgear/bmx adaptor(acepts BMX style feewheels) from Sheldon Brown's web page: http://sheldonbrown.com/harris/fixed-hubs.html
Another one to check would be the new Sram i-motion9-disc(to mount the output sprocket instead of the disc) (9gears 340% change) (for sale next year).
Not cheap, not that complicated, but still needs a jackshaft and enough room on the frame for al this to work
