Abstract: A bicycle drive unit is provided that includes a motor, a crank axle, a power transmission axle and an output part. The motor includes a crank axle receiving hole. The crank axle is rotatably disposed in the crank axle receiving hole of the motor. The power transmission axle is separate from the crank axle and arranged to transmit rotation of the crank axle. The output part is operatively coupled to the motor and the power transmission axle to combine a rotational output of the motor and a rotational output of the transmission mechanism together.
