i know that the tire width is custom size but what about the rim diameter as well as the effective rim diameter because when it comes time to replace tires will normal childs mountain bike tires work? as often childs mountain bikes use sizes from 18 to 24 inches depending on the age range and size of the bike.
and what about the spokes.
i have not gotten my radwagon 4 assembled yet as i got it during the winter but when i get it assembled and going eventually the inevitable will happen i will need to replace broken spokes and i was wondering if the spokes are standard lengths so custom length would not have to be cut and threaded.
