The People Powered Vehicle, or PPV, was a two-person pedal-powered car introduced in the United States during the oil crisis of the early 1970s.
This tricycle was manufactured with a three-speed, floor shift, open type transmission with a single-wheel drive.
Sometimes bicycle accessories were added, e.g. squeeze bulb horn and a rear view mirror.
The PPV was designed for two adult riders, and with frame and body the total weight could approach three times that of a conventional single-rider bicycle.
An upgraded version of this vehicle is currently (2011) being offered by the International Surrey Company Ltd. under the trade name Impello.
