I should have mentioned that this one does exist.  It just doesn't seem to
be available in the northern hemisphere.  A sturdy one that looks like one
I'd like to have is the Super version on this page.

As for the chipper shreader and people power, would it be possible to do it
with the sort of gearing you'd use to climb a steep hill on a bicycle so it
would be slower than the powered version (like hand turned grain mills are
slower than electric versions) but still effective?

As for the shreader, I've seen some that arborists use to pull behind their
trucks that shred rather than chip.  But I don't know about smaller home
versions.
