About this project
Frédéric Koch started from a long-wheelbase recumbent frame and transformed it for long journeys: a 26″ rear wheel instead of 700c, a 20″ front wheel, a new fork and V-brakes.
It has a NineContinent RH205c rear motor, a 48 V 21 Ah battery, a 150 W panel fixed on the bike and a 120 W solar case for stops, all at only 37 kg. “Farther, cleaner, faster. Ecology at the service of travel and discovery.”
