A motorized scooter includes a platform (20), a steering column (10) pivotally secured to a front of the platform (20), a front wheel (12) mounted to the steering column (10), a rear wheel (14) mounted to the rear of the platform (20), a power train (30) extending between the platform (20) and the rear wheel (14) and a motor (32). The power train (30) has a driving sprocket (34), a driven sprocket (38), a chain (36) reeved around the driving and driven sprockets (34, 38), and a bracket (39) supporting the axle (322) and the driving sprocket (34). A freewheel mechanism (342) is fitted in the driving sprocket (34) whereby in a driving mode the turning axle (322) indirectly turns the rear wheel (14), and in a freewheel mode the turning rear wheel (14) does not result in the turning of the motor (32).
