A drivetrain includes a main shaft, driven by an electric motor, and a wheel output shaft. Two gearwheels, mounted around the output shaft to rotate freely, are meshing with respective main pinions integral with the main shaft. A clutch system car engage either one of the gearwheel with the output shaft. To reduce the load applied to the gearwheels, the drivetrain includes a recirculation shaft, freely rotating relative to a housing of the drivetrain, and two recirculation pinion, integral with the recirculation shaft, each meshing with a respective gearwheel. When the clutch system engages one of the gearwheel with the output shaft, the recirculation shaft is driven by the main shaft through the other gearwheel meshing with the respective main and recirculation pinions, and the output shaft is driven both by the main and recirculation shafts, through the engaged gearwheel meshing with the respective main and recirculation pinions.
