The invention discloses a bicycle gear with motor assistance. The bicycle gear comprises a gear set, a bearing and an assistance mechanism, wherein the gear set comprises a transmission gear and a torque gear, the transmission gear is used for being connected with an external chain and changing the transmission ratio; the bearing is used for assembling the gear set and connecting the power assisting mechanism; and the power assisting mechanism comprises a torque sensor, a motor, a control module and an antifouling shell. According to the bicycle gear with the motor assisting power, the torque gear and the assisting power mechanism are additionally arranged in a flywheel set of an existing variable-speed bicycle, signals are transmitted to the control module through the torque sensor, and the control module controls the motor to provide torque assisting power with the proper magnitude according to the magnitude of torque after receiving the signals. When the motor is not in the working state, the motor rotates along with the bearing, the storage battery can be charged, it is guaranteed that the power assisting mechanism has enough electric power when torque assisting power needs to be provided, and practicability is improved.
