How Do They Stay in Business?

Within the last 10 years, we have seen big boys like BikeE, Vision,
and Burley ultimately fail to stay afloat with re***bents.  Within the
same period, we have seen the birth of Bacchetta, Volae, Barcroft, and
others as well as the endurance of Easy Racers and RANS.  So how do
they do it?  Are these companies making a profit after they pay their
bills?  How do they get their products in the dealers store?  RBR in
State College, PA (great store by the way) stocks no dual 26 LWB
RANS.  Jays in Philly (also nice store) stocks only RANS but is also a
dealer for Easy Racers and Bacchetta.  I just don't get it.
