In this particular case, it actually improves the reduction. In the stock form, the motor spins 5 times for every shell revolution, after the conversion, the shell is stationary, and the motor spins 6 times for every shaft revolution.

Interesting project. I love all the stuff like this on these forums.
How does your setup compare to something like the new Bafang BB-drive systems? Efficiency, power, noise? Great job!

This is much more powerful than the BBS02, but it is also much noisier. I am looking forward to the LightningRods kit, which should be available within a month or so, and if it is as quiet as I have been told, I will not need this project...wonderful as it is...(it was fun)

sad to hear 
hope you will still go for the dual freewheel jackshaft drive with your GNG drive?
I'm not sure what make this drive so load. It should be less noisy.

How is this the L-R project going? I went here http://www.lightningrodev.com/ and don't see any detail yet it says available. I'm new here and basically designing a monster on-road uphill monster. My commute to work is straight up 1500' and down 1700'. My design goal is just to go up at 18mph minimum, downhill is a glide so no time/speed/power issues.
Of course, this would spec for "off-road" use only.
Thanks
