We study the properties of the analogue of R-diagonal operators in the setting of bi-free probability. Products of bi-R-diagonal pairs of operators that are *-bi-free are studied and powers of such pairs are found to also be bi-R-diagonal. It is moreover shown that the joint *-distribution of a bi-R-diagonal pair of operators remains invariant under the multiplication by a *-bi-free bi-Haar unitary pair and equivalent characterizations of bi-R-diagonal pairs are developed.
