I can't believe that 3 people all gave you a hard answer
today   

# man gpasswd

Could just run

usermod -G "" fred1


USERMOD(8)
       -G group,[...]
              A  list  of  supplementary  groups which the
user is also 
a member of.  Each group is separated from the next by a
comma,
              with no intervening whitespace.  The groups
are subject to 
the same restrictions as the group given with the  -g 
option.
              If the user is currently a member of a group
which is not 
listed, the user will be removed from the group. This
behaviour
              can be changed via -a option, which appends
user to the 
current supplementary group list.

That might remove fred1 from more than just the wheel
group?!

While I'm not sure I would characterize removing 6
characters from a
file as hard, I can't argue with Ed's suggested solution
which does
exactly what was requested in a very straightforward way. If
the price
of suggesting hard solutions is learning easy solutions, I'm
willing
to pay that price any day.
