Flux-flow resistance and Hall effect were measured in a Bi2+xSr2-yCuO6 crystal in the superconducting mixed state. The Hall mobility saturates to a temperature-independent plateau at H=0.9 mT-1 at high field (H>5 T), while the resistance varies nearly as log(H). The absence of features to identify Hc2(T) is contrasted with other type-II superconductors of similarly low Tc=7 K.
