Chainguards? tons are discarded from every Kids BMX bike assembly.
they ship one in the carton, never to be used.

you might seek out a metal one.. next..

Traditional, ones on the streets of Amsterdam are of a truck tarp fabric
over a steel support frame, no molded plastic.

[ If you get the German Hebie chainglider ,
it's plastic form is designed to go over the whole chain to keep it cleaner
and keep the long skirt out of the chain..

either 38t or 42 t chain ring & nexus or rohloff hub.
an 1 from column A , 1 from column B approach.]
