The embodiment of the invention discloses a driving and speed changing integrated middle-arranged device and an electric power-assisted bicycle. The middle-arranged device comprises a main driving unit, an auxiliary driving unit and a transmission mechanism. The transmission mechanism comprises a crank connecting shaft, a planet carrier, a planet wheel, a sun wheel and a transmission wheel; the transmission wheel is an annular structure, an inner gear ring is arranged on the inner side of the transmission wheel, an outer gear ring is arranged on the outer side of the transmission wheel, and the transmission wheel is fixedly connected with a crankset; the planet carrier is arranged on one side of the transmission wheel, and the crank connecting shaft is fixedly connected with the planet carrier; the planet wheel is arranged on the planet carrier and engaged with the sun wheel and the inner gear ring of the transmission wheel; a main driving unit is connected with an outer gear ring of the transmission wheel; and the auxiliary driving unit is connected with the sun gear. The driving and speed changing integrated middle-arranged device can achieve a power-assisted driving function anda speed changing function at the same time, and is low in cost, small in size, light in weight and easy to install and maintain.
