Manual-automatic integrated internal variable speed hub and bicycle

The invention belongs to the technical field of internal transmissions, and particularly relates to a manual-automatic integrated internal variable speed hub and a bicycle. The manual and automatic integrated internal variable speed hub comprises a mandrel, a transmission mechanism, a driving mechanism, a control mechanism, an input piece and an output piece, the driving mechanism drives the transmission mechanism to rotate to a specific angle in a manual and/or automatic mode, the transmission relation of all components in the transmission mechanism is changed, and the transmission ratio of the transmission mechanism is changed. The manual-automatic integrated internal speed change hub has two modes of manual speed change and automatic speed change, in the manual speed change mode, a rider can freely change gears according to actual road conditions, and the riding flexibility is improved. And the gears are automatically changed according to a program in the automatic speed changing mode, so that the riding c
