An automatic internal transmission and a bicycle are provided. The automatic internal transmission includes a hub shaft, an input mechanism, an output mechanism, a transmission mechanism having a first planetary gear train and a second planetary gear train, and an automatic shifting control mechanism having a clutch control unit and a centrifugal block being connected to the output mechanism and the clutch control unit. The centrifugal block can rotate relative to the output mechanism to a first state in a first direction, to drive the clutch control unit to rotate, so that a driving force is transmitted via the first planetary gear train. The centrifugal block can further rotate relative to the output mechanism to a second state in the first direction, to drive the clutch control unit to further rotate, so that the driving force is transmitted via the second planetary gear train.
