Hi there! I've got the same problem as you. I've aquired an old royal knight but can't seem to find info on it anywhere. Mine says made in canada on it but the rims say made in taiwan I think. The rims seem to go with it so I don't believe they we're put on after. It has a coaster brake and is in very rough condition. I'm gonna be tearin it down and fixin it to ride. Lemme know if you find any info. Cheers!
