Shawn Ryan, a passionate DIYer without formal engineering or pro cycling credentials, built a solar-powered cargo e-bike that covered over a thousand kilometers and numerous Alpine mountain passes entirely fueled by sunlight.
- Solar-powered bike covered 1,000+ km and steep Alpine passes
- No external electricity allowed to remain in the competition
- Next adventure planned from France to China by solar bike
What happened
Shawn Ryan constructed a solar electric-assist cargo bike by outfitting a standard model with solar panels, a 250W motor, and a battery management system he developed himself. Setting out from the UK after initial testing, he participated in the Sun Trip, an international solar bike event focusing on long-distance journeys powered solely by the sun.
During the Alpine edition of the race, Ryan faced challenging climbs such as the Col du Galibier and the Col de l'Iseran—the highest paved pass in the Alps—spanning more than a thousand kilometers across French terrain. Strict rules disqualified any rider who recharged using mains electricity, underscoring the commitment to renewable energy and independent travel.
Why it feels good
Ryan’s trip highlights the accessibility and potential of solar energy combined with human effort. Without professional assistance or engineering background, he demonstrated how sustainable technology can empower individuals to explore demanding environments without relying on fossil fuels or grid power.
His success also promotes grassroots innovation, showing that with ingenuity, solar-powered transportation can be practical and adventurous. This inspires hope for cleaner, more self-sufficient ways to travel, reduce carbon footprints, and engage with nature in eco-friendly ways.
What to enjoy or watch next
Following this successful Alpine journey, Shawn Ryan plans to extend his solar-assisted travels from France all the way to China, promising even greater challenges and discoveries. This upcoming adventure will test solar e-bike capabilities across diverse landscapes and cultures, further advancing the conversation about renewable travel.
For those interested, videos of Ryan’s ride are available, showcasing the rugged terrain, his bike’s solar setup, and the realities of managing power, navigation, and self-repair on a solar-only expedition. This ongoing saga is a must-watch for fans of innovation, sustainability, and outdoor adventure.
