The Bethe Strip of width $m$ is the cartesian product $\B\times\{1,...,m\}$,where $\B$ is the Bethe lattice (Cayley tree). We consider Anderson-likeHamiltonians $H_\lambda=\frac12 \Delta \otimes 1 + 1 \otimes A+\lambda \Vv$ ona Bethe strip with connectivity $K \geq 2$, where $A$ is an $m\times m$symmetric matrix, $\Vv$ is a random matrix potential, and $\lambda$ is thedisorder parameter. Under certain conditions on $A$ and $K$, for which wepreviously proved the existence of absolutely continuous spectrum for small$\lambda$, we now obtain ballistic behavior for the spreading of wave packetsevolving under $H_\lambda$ for small $\lambda$.
