The invention discloses a driving part, a power assembly and an electric bicycle, the driving part comprises a middle shaft, a shaft sleeve, a first clutch, a second clutch and a power input piece, the shaft sleeve is sleeved on the middle shaft, the shaft sleeve and the middle shaft are coaxially arranged, power is transmitted between the shaft sleeve and the middle shaft through the first clutch in a one-way mode, and the second clutch is connected with the power input piece in a one-way mode. Power is transmitted between the power input piece and the shaft sleeve in a one-way mode through the second clutch, the power input piece and the shaft sleeve are coaxially arranged, manpower and motor power can be input independently or input at the same time, interference between the manpower and the motor power is avoided, and the power transmission efficiency is improved. And no transmission system is arranged between the first clutch and the second clutch, so that invalid transmission and invalid meshing are avoided.
