A bicycle derailleur motor gear unit configured to reduce motor speed of a motor and transmit motor torque of the motor to a derailleur is proposed. The bicycle derailleur motor gear unit comprises an output shaft, a fixed sun gear, an output sun gear rotatable relative to the fixed sun gear, the output sun gear being fixedly coupled to the output shaft, a plurality of planet gears, and a carrier rotatably and revolvably supporting the planet gears. Each of the planet gears has a first gear that engages with the fixed sun gear and a second gear that engages with the output sun gear, the first gear and the second gear being coaxially coupled to each other. The fixed sun gear, the output sun gear, the first gear, and the second gear have tooth counts, respectively, such that the fixed sun gear, the output sun gear, the first gear, and the second gear lock while an external force is exerted to the output sun gear.
