Vehicle, Mobility and Transportation Design Velo Solex Revival Electric Bicycle by Asbjoerk Stanly Mogensen The original Solex was introduced in the year 1949 as a gasoline moped. Having the right to use the Solex brand via a license agreement, designers have taken the design from that time and converted into an electric bicycle. The geometry of the frame and the shape of the frame are the same as in 1949. Designers have converted the frame to accommodate an electric motor and a battery. A lot of modern materials have been used to create Velo Solex Revival such as aluminum for the frame.
