Abstract
In this paper we consider a nonsingular bounce scenario with non-minimal kinetic coupling between two scalar fields.We derive the constraints on the model parameters from the finiteness of the physical quantities at the classical level and from the relation between the late-time accelerated expansion and particle production up to the bounce phase. We then determine the allowed parameter space for the model.
