His Vision of the Sun Trip

“For me, the Sun Trip is one of the rare flagship experiences of the 21st century. It traces the main axes of sustainable and exciting development in the field of mobility. It is a great human adventure! It is also the application of modern technology that consumes very little raw material!

It is the possibility for the young and the not so young, for people in good shape or with some health problems, for athletes or less athletic, for all those who are interested in sharing this solar roaming and / or through sports performance, to live TOGETHER an unforgettable experience! “
