About this project
Bertrand & Marie-Dominique took part in Sun Trip Auvergne-Rhône-Alpes 2026 and Corsica Sun Trip, the long-distance adventure on solar-powered bikes held since 2013.
The machine is a solar trike.
Bertrand and Marie-Dominique have loved cycling and travel for years. They discovered recumbent bikes on the Corsica Sun Trip and adopted them for good. As long-time hikers in the Alps, they could not resist combining both and signed up to take on the Alpine passes.
