On the bicrossproduct structures for the ${\cal   U}_\lambda(iso_{\omega_2... \omega_N}(N))$ family of algebras
  It is shown that the family of deformed algebras ${\cal U}_\lambda(iso_{\omega_2... \omega_N}(N))$ has a different bicrossproduct structure for each $\omega_a=0$ in analogy to the undeformed case.
