I realize there are a few options and some are advertised on the sides of this forum, but what's the general prevailing wisdom? Let's say you want to place a large chain sprocket on the left of the rear wheel but you want to retain the disc brake so the brake and sprocket can't interfere. What's a reasonable method and which parts should be employed? And there are really two categories of rear driven sprockets, the freewheel ones and the fixed ones. E-bikes often use a freewheel, but ICE-bikes usually are fixed.
