In this study, we explore the Aether scalar tensor theory within the context of Friedmann–Lemaître–Robertson–Walker (FLRW) cosmological evolution. We construct explicit models for several prominent cosmological bounce scenarios, including symmetric bounce, super bounce, oscillatory bounce and matter bounce. Our approach integrates a dark matter component modeled as an Extended Bose–Einstein Condensate, while the dark energy components, specifically, [Formula: see text]. To validate the feasibility of our reconstructed models, we analyze the equation of state parameter [Formula: see text] and the [Formula: see text] plane, where [Formula: see text]. This examination includes stability analyses to ensure the robustness of our models under various conditions. Our findings show that the theoretical predictions of these models are consistent with current observational data, highlighting their potential to accurately describe cosmic evolution.
