That's really cool. I was gonna use a dana for a motorized bike transmission but lost interest. Mainly because of the plastic gears.

Weird how dana over engineered every other part, and then used a crappy bunch of plastic to shift it.

I agree. I was a little surprised when I took it apart and found the plastic parts. I never did figure out how to disassemble that piece. I was too worried that I would break it and it would be impossible to find a replacement.
 
My thoughts exactly. I have an NOS one, and figured out (theoretically, on paper) how to mount it as a jackshaft/transmission, worked out how to put a sprocket onto the crankshaft, and while mocking it all up, realized the cables would be too short so the gripshift wouldn't reach. I could make new cables, but I've built a lot of custom motorized bikes, and just knew if I put it all together, shifting it under power would destroy those cheap gears, and the grip shift would strip out eventually. Sooner, not later.

With your set-up, at least for the gear replacement, it looks more plausible.

Sadly, I've had my fill of blowing up cheap chinese motors, and haven't built any in a while.

Very cool bicycle . I restored a 1920s English Sunbeam with a 2 speed gear box in the front sprocket . Thing rides like a dream . As far as stopping with the rod brakes , that's another story

The Dana is a very cool novelty, but I certainly wouldn't want one on my daily rider! The gearbox creates a lot of drag. That's probably why it didn't catch on.
