Originally, the  Leitra  was built to enclose rather small Carl- Georg Rasmussen (above left). An early mid-80's model, without front suspension, but still going strong, stands in the workshop, and occassionally gets to be used for errands, or during bicycle meets etc. Over time, the undercarriage kept being modified and growing bigger until the present size, which is sufficiently "airy" inside to accomodate the majority of riders. Since  Leitras  are custom- built to order for in- advance known customer measures, the frame and other parts have been developed with flexible assembly in mind. The end result is an, even for hand- built recumbents, unusually  o p t i m i z e d  velomobile, adapted to the riding style and capabilities of a given individual.
    That said, there is always one customer, that breaks the mould. And here not only figuratively  speaking, but in the flesh as well. The picture above shows that Human Exception, 197-cm long Andreas Fuchs sitting inside a broken plug, i.e. the very object from which the mould for the  Leitra  fairing has been made.
    Broken on purpose, of course. Andreas, who happens to be the premier human- powered transport and practical velomobile  proponent in Switzerland, has been driving his  Leitra  for a few years with a makeshift prototype fairing, because the standard one, roomy enough for most people, was simply too cramped for him. Ergo he arranged with the builder to come and help him make a bigger one, which'd also accomodate other XXL- sized customers (many recumbent riders are quite tall. . .  in part because, when they cannot find large enough upright bike frames, and have to order them custom- made, the equally- high prices of recumbents becomes less of an issue).
