A centrally mounted driving mechanism for a power-assisted bicycle is provided according to the present application, including a housing (1), a motor (2), a planetary gear (4) mechanism in transmission connection with a motor (2) output shaft, a bevel gear driving end (9) and a bevel gear driven end (10) engaged with the bevel gear driving end (9). The bevel gear driven end (10) is connected with a crankset (13), and the planetary gear (4) mechanism includes a planetary gear (4) and a planetary gear output bracket (5). The centrally mounted driving mechanism further includes a bevel gear support (8) sleeved outside the planetary gear output bracket (5). A clutch (6) is provided between the planetary gear output bracket (5) and the bevel gear support (8), and the planetary gear output bracket (5) is in transmission connection with the bevel gear support (8) through the clutch (6). The bevel gear driving end (9) is coaxially and fixedly connected with the bevel gear support (8), and a support assembly (7) is provided outside the bevel gear support (8), and the support assembly (7) is configured to support the planetary gear output bracket (5) and the bevel gear driving end (9). The length of the centrally mounted driving mechanism is relatively small in the axial direction, making the overall structure more compact, which is convenient for the power-assisted bicycle to be mounted with a battery with larger capacity, and thereby improving the battery life.(Fig. 1)
