  Constructing new topological materials is of vital interest for the
development of robust quantum applications. However, engineering such materials
often causes technological overhead, such as large magnetic fields, specific
lattice geometries, strong spin-orbit coupling, synthetic dimensions, or
dynamical superlattice potentials. Simplifying the experimental requirements
has been addressed on a conceptual level - by proposing to combine simple
lattice structures with Floquet engineering - but there has been no
experimental implementation. Here, we demonstrate topological pumping in a
Floquet-Bloch band using a plain sinusoidal lattice potential and two-tone
driving with frequencies $\omega$ and $2\omega$. We adiabatically prepare a
near-insulating Floquet band of ultracold fermions via a frequency chirp, which
avoids gap closings en route from trivial to topological bands. Subsequently,
we induce topological pumping by slowly cycling the amplitude and the phase of
the $2 \omega$ drive. Our system is well described by an effective Shockley
model, establishing a novel paradigm to engineer topological matter from simple
underlying lattice geometries. This approach could enable the application of
quantised pumping in metrology, following recent experimental advances on
two-frequency driving in real materials.
