Almost everyone knows about the German Twike side-by-side tandem
(Sociable). A rendering of a similar vehicle I saw this morning (I
don't recall where) was the next step for 2007- the next step for an
American Twike, since that Twike is now being imported. We have had
several come and go starting about 1970 with the PPV rental. These
are recumbents, but this model never caught on like DF bikes have, not
even like recumbents have in a small percentage of the market.
No worry, when Venzuela and OPEC stop the oil flow, we are already so
prepared with our bents, that the only shortage we will suffer is the
lack of Power Bars due to delivery problems...
Seriously; I hope these sociables/tandems evolve from rendering and
clay models within my lifetime.
