We show that one can extend the definition of Hopf cyclic homology with coefficients such that one can use bialgebras and
a larger class of coefficient module/co-modules. With the help of this extension, we calculate the bialgebra cyclic homology
of
Uq() the quantum deformation of an arbitrary semi-simple Lie algebra and
H \cal H
(
N) the Hopf algebra of foliations of codimension
N, with several coefficient modules.
