Now how did the smaller drive sprocket get in there?
And you got roller bearings spinning the shaft?
(edit) Just saw first pic.

This is real slick! Makes me wish I had a welder.
And it's GREAT that you don't need a freewheel crank.
Yes the freewheel on the motor side is welded and only used as a regular sprocket.
Pedal backwards, Hmm never occured to me to do that but yes I could.
I welded the motor side freewheel so it could be pedal started. The original concept for the motor side freewheel was to reduce drag with the motor not pulling.
