Does anyone know where I can find an enclosed trailer to transport bicycles? Something small and lightweight, but aero... I swear I have seen ads for them before but when I google for any combination, all I can find are boxy motorcycle trailers, or trailers for the bike itself... I am looking for a way to transport a bicycle with a sports car, but protected from the elements (i.e. no trailer hitch rack, rear rack, etc.). Anyone? Thanks.
