We predict three different, quite unusual transport properties of an underdamped Brownian particle in the form of current and force of opposite signs. Their origin is a subtle interplay between the stability of coexisting attractors, noise-induced metastability, and transient chaos. Numerical simulations are complemented by intuitive explanations of the basic mechanism and analytical approximations.
