To answer the question, "When is a Bike a Velomobile?"- I think in terms of perception, people would just think of this as a modified bike, because that's what it started out as. Similar to if you take a motorcycle and add two wheels, nobody's going to call it a car. Or put a fifth-wheel on a Corolla and nobody will call it a truck.

I recall reading in photography that perfection was not achieved when there was nothing else to add, but when there was nothing else to be taken away, and I think that motto could be applied here.
