People like bicycle, do not like tricycle or quadracycle--4 wheels

friction), also is easy and safe to be ridden.
Ideally cyclist should like to ride a unicycle, because friction only
existed between one wheel and the ground (cut friction in half compare
with on a bicycle), but ride a unicycle need special skills and not
safe.
Based on a normal bicycle, this "Half Bicycle" modified some parts:
Cyclist’s set is moved backward (also hand-bar is extended backward),
to make sure centre of gravity of the bicycle is around on back wheel
B.
Cyclist can ride this bicycle as a normal bicycle by moving centre of
gravity toward front. If road condition is good, cyclist want to
increase speed, he can move centre of gravity backward little bit and
make sure the centre of gravity is on back wheel B. At the same time,
front wheel A will be left from the ground, the bicycle becomes a
unicycle, only wheel B touches the ground. This means friction between
wheels and the ground is cut in half. In other words this bicycle only
needs half amount of human power to travel in same speed (or same
distance) as a normal bicycle.

This is absolute nonsense. When riding a wheelie, far more energy is
expended maintaining balance than could possibly be lost to rolling
resistance.
