Hi all.
Have just been skimming through this thread, and the level of the discussion is far beyond my interest, (yes I know, I do not have to read it...) but however, there is one thing that might help: a flywheel. It stores the power variations from the biker. But it also adds weight to the bike... Some kind of compromise might be nice. This was just for fun, but even serious things can be fun.
