A gear-shifting device includes a first motor having a first stator. The first stator turns clockwise and counter-clockwise, creating a wobbling action. The device further includes a compound planetary transmission, made up of a transmission ring attached to a ring gear. The compound planetary transmission receives power from the first stator. A second motor having a second stator, turns clockwise and counter-clockwise. The device further includes a shift assembly, made up of a drum, a cap, and a pinion gear. The pinion gear receives power from the second stator. The drum locks with the pinion gear such that the drum rotates with the pinion gear. The transmission ring is attached to the drum, such that the transmission ring moves laterally as the drum rotates. The ring gear locks and unlocks with the cap as the drum rotates. The wobbling action enables the locking.
