Abstract
We show that if is a metric space which admits a consistent convex geodesic bicombing, then we can construct a conical bicombing on , the hyperspace of nonempty, closed, bounded, and convex subsets of (with the Hausdorff metric). If is a normed space or an -tree, this same method produces a consistent convex bicombing on . We follow this by examining a geodesic bicombing on the nonempty compact subsets of , assuming is a proper metric space.
