Made by Screenhouse Productions and directed by Paul Bader, it was first aired on the ITV regional network Yorkshire Television in 1991. In the show, Adam Hart-Davis, dressed in the pink and yellow cycling clothes that would become the show's trademark, rode around the YTV region (including Yorkshire, Norfolk and Lincolnshire) on a matching pink and yellow bicycle, stopping in a particular area to tell the stories of scientists that lived or were born there. These stories were embellished by experiments, performed on the street by Hart-Davis, generally using bits of wood and junk from a trailer on his bike.
