Imagine visiting a museum to study a penny-farthing—a classic bicycle with a giant front wheel and a tiny rear one—not out of idle curiosity, but with the intent to build one yourself. Then, you decide to hop atop this contraption with no gears, solid rubber tires, and virtually no brakes and eventually take it around the world. It sounds nearly impossible, yet that is exactly what Joff Summerfield did. After designing and constructing his own custom penny-farthing, Joff departed Greenwich, England, in 2006, coming home two and a half years later. Five years after his return, he set out to do it again in the opposite direction, though that effort ended in tragedy. Joff’s mechanical ingenuity, while impressive, was nothing compared to the resourcefulness he needed on the road. His travels required constant improvisation, from overcoming dysentery in Turkey to navigating Tibet without a visa to subjecting himself to DIY dentistry in California. In this episode, Joff joins us to share the unexpected challenges, remarkable encounters, and sheer determination behind his journeys on two highly unequal wheels.
