Not much has been written about Ettore´s bicycle, and either much on the T72, his bicycle engine. In this article we don´t intend to say everything about this issue either, we´ll just show some pictures! Both the (old) bicycle as well as the T72 engine are in the collection of a French collector, who wishes to remain anonymous. The pictures were provided by (and are copyright of) Patrick Arnaud. Thanks to him for providing these!
Above an old example of Ettore´s bicycle, design from 1913. Doubtfull however is, if this really is an original from that date, or a replica from the 1950´s (it seems to me that the parts used indicate mostly the later date. We know for sure however, that the bicycle shown below is a recent replica, built from 1913 drawings and details from the Bugatti Trust. Only three are known.
It is shown here to make clear the basics of Ettore´s design, where basically the usually used tubes are replaced by 4 small diameter tubes placed in a square, and connected by spacers.
The smallest Bugatti, measures only 12.66 cc. recently photographed in France, the one prototype built in 1944. Dimensions are 24 x 28, plus supercharger and gear driven overhead valve gear. It was capable of 10,000 RPM. The detail pictures below speak for themselves, really a very fine piece of engineering!
