What Is A Re***bent Bicycle?

What is a re***bent bicycle?
A bicycle where you sit back in a full seat with your legs in a
horizontal position. This puts the body in a position where there is
less wind drag from the legs, but still maintains the optimal angle
between back and legs as on a conventional bicycle, provides a more
comfortable riding position with no weight on the wrists, and provides
a natural view looking forward.
If you study where the energy goes in riding a bicycle you will find
out that at speeds over 25 km/hour, 90% of your energy is used to
overcome wind resistance.

(I found the above on www, it seems to make it clear for those who
don't know.)
