Michel de Broin is the artist who came up with this idea. They went to court to protest the ticket and it was thrown out in the end.
Here is what he says about the project on his site.
“In this project, all superfluous devices were removed from an 86’ Buick Regal – the engine, suspension, transmission and electrical system – thereby reducing the weight of the vehicle whilst preserving its appearance. It was then equipped with 4 independent pedal and gear mechanisms that make it possible for passengers to form the self-propulsion group. A cutting edge transmission technology was developed to transmit the power supplied by the passengers to the drive wheels and to vary the reduction ratios between cyclists and wheels, so as to ensure their progressive coupling for start-ups. With a top speed of around 15 km/h, the vehicle’s resistance to the culture of performance is raised to an unprecedented level.”
I don’t know….I say buy a bike!
