  We refute the criticism expressed in a Comment by P. J. Mart\'{\i}nez and R.
Chac\'on [arXiv:2105.09308] on our paper Phys. Rev. E \textbf{97}, 032219
(2018). We first show that our paper is free of any mistakes and that the
criticism expressed in the Comment is based on a misunderstanding or
misrepresentation of what is actually claimed in our paper. We also show that
the argument presented against the general formalism mentioned in the Comment
is invalid because it is based on a confusion by the authors of the Comment
between the general formalism per se and its lowest order approximation. In
fact, the arguments contained in the Comment do not show that such a formalism
is in general incorrect, as the authors of the Comment suggest, but rather that
the supposedly universal predictions of the theory of ratchet universality are
in general incorrect. In addition, we show that other arguments presented in
Comment are invalid because they are based on incorrect equations.
