  We obtain the general cosmological evolution equations for a classically
consistent theory of bimetric gravity. Their analytic solutions are
demonstrated to generically allow for a cosmic evolution starting out from a
matter dominated FLRW universe while relaxing towards a de Sitter (anti-de
Sitter) phase at late cosmic time. In particular, we examine a subclass of
models which contain solutions that are able to reproduce the expansion history
of the cosmic concordance model inspite of the nonlinear couplings of the two
metrics. This is demonstrated explicitly by fitting these models to
observational data from Type Ia supernovae, Cosmic Microwave Background and
Baryon Acoustic Oscillations.
