Imagining a design for transmission from a left side output motor (China Girls, etc) to a freewheeling sprocket on the left side of the bottom bracket. This would require a bottom bracket with basically two axles - sprockets on both sides connected and freewheeling on a central pedal crank axle. Someone would have to create this of course as it is not available anywhere. Simpler than jack-shafting to the right side though with less friction and fewer parts to keep tuned and adjusted. I wonder if it could be made with any off the shelf parts or would require some real innovation and a machine shop.
Would then have all the advantages of a jack-shaft. I'd like to see a heavier - than - bicycle sprockets and chain on the right side as well to a sturdy rear hub with internal gears. Anyone?
