  In a group, a generalized torsion element is a non-identity element whose
some non-empty finite product of its conjugates yields the identity. Such an
element is an obstruction for a group to be bi-orderable. We show that the
Weeks manifold, the figure-eight sister manifold, and the complement of
Whitehead sister link admit generalized torsion elements in their fundamental
groups. In particular, the Whitehead sister link, which is the pretzel link of
type (-2,3,8), can be generalized to hyperbolic pretzel links of type
(-2,3,2n), n>3. These give the first examples of hyperbolic links whose link
groups admit generalized torsion elements.
