looking for ideas/designs to create a bike powered compost materials shredder?
AtomRat is right, look at existing shredder designs. I suspect a hand cranked shredder would be relatively easy and cheap to modify to bike powered.

I think that you should take a look at Hammer Mill designs, as they are rather basic, and usually run off a motor, that you can substitute for the bicycle. I don't know a heap about them, but it should be something of interest to you for your project.
