Title: Drive wheel with an internal combustion engine housed in its interior

Abstract: This invention relates to a drive wheel for motor vehicles, in particular motorcycles, having an internal combustion engine arranged in the wheel interior. According to the invention, the wheel rotates about a pivot fixed to the engine block and receives its motion, through a suitable transmission, from a drive shaft emerging from that side of the engine block opposite the side to which the wheel support pivot is fitted. This arrangement of the wheel and the drive shaft enables the internal space of the wheel to be utilized to the maximum extent for arranging the engine-transmission assembly in suitable manner.
