An automatic internal transmission (100), comprising a hub shaft (10), an input mechanism (20), an output mechanism (30), a transmission mechanism (40), and an automatic shift control mechanism (50). The transmission mechanism (40) comprises a first planetary gear train (41) and a second planetary gear train (42). The automatic gear shifting control mechanism (50) comprises a centrifugal block (501) and a clutch control unit (53), the centrifugal block (501) being connected to the output mechanism (30), and the centrifugal block (501) being connected to the clutch control unit (53). The centrifugal block (501) can rotate relative to the output mechanism (30) to a first state in a first direction, so as to drive the clutch control unit (53) to rotate, so that a driving force is transmitted by means of the first planetary gear train (41). The centrifugal block (501) can further rotate relative to the output mechanism (30) to a second state in a first direction, so as to drive the clutch control unit (53) to further rotate, so that the driving force is transmitted by means of the second planetary gear train (42). A bicycle, comprising a bicycle body and the automatic internal transmission (100).
