Karl Drais and the Bicycle

Hop on for a rolling adventure back to 1817! Meet Karl Drais, the clever inventor who built a wooden two-wheeler that changed how people moved. This short story is filled with brave experiments, bumpy roads, curious onlookers, and the very first public ride that proved a person could glide without a horse. Why this story is special for kids: It shows how one simple idea and careful tinkering can spark a transport revolution. Young listeners will love the sounds of wheels, the squeaks of a workshop, and the excitement of a long straight road where a daring ride begins. Historical Fun Fact: Karl Drais made his famous public ride in 1817, covering about seven miles in roughly one hour—about the speed of a trotting horse! Did you know? The first draisine had no pedals; riders pushed along with their feet and learned to balance while they glided. Ben & Pia guide you through the scene with Storyteller bringing the creak of wood and the rush of wind to life.
