The invention relates to a bottom bracket gear shift device with a sensor assembly (123) for an electric bicycle and to an electric bicycle comprising such a bottom bracket gear shift device with a sensor assembly (123), in particular in the form of a central motor. The bottom bracket gear shift device with a sensor assembly (123), in particular for a muscle-powered vehicle with an electric auxiliary drive, is equipped with a bottom bracket shaft (18) mounted in a gearing mechanism housing (121) and an output shaft (122), wherein the bottom bracket shaft (18) is designed to receive pedal cranks (7), and the output shaft (122) is guided out of the gearing mechanism housing (121). At least one sub-gearing mechanism (74) is located in the gearing mechanism housing (121), and the at least one sub-gearing mechanism (74) has at least one selector shaft (67) on which at least two gear ratios can be set. At least one shaft is directly or indirectly connected to the first of at least two printed circuit boards (44, 45), and at least one housing part of the bottom bracket gear shift device (10) is directly or indirectly connected to the second printed circuit board of the at least two printed circuit boards (44, 45). At least two printed circuit boards are equipped with electronic components (77) which forward at least one signal that represents the torque or the rotational speed being applied to the shaft, and the at least two printed circuit boards (44, 45) are located in the direct vicinity of each other.
