The
electrical
bicycle
and
bike
are
both
environment-friendly
vehicle.
The
electical
bicycle
is
more
convenient
and
comfortable.
But,
its
price
is
high.
And
it
is
heavy.
The
bike
is
light
and
cheap.
What's
more,
the
bike
can
help
you
to
build
up
your
body.
In
my
opinion,
the
old
people
should
ride a
electrical
bicycle
and
young
people
should
ride
a
bike.刚刚写的
