The invention discloses a small-sized self-balancing scooter. The small-sized self-balancing scooter comprises a platform, two wheels arranged on the two sides of the platform correspondingly, and a direction control rod arranged on the platform. The small-sized self-balancing scooter further comprises two pedals arranged on the outer sides of the two wheels correspondingly. The pedals are connected with the small-sized self-balancing scooter through hinges. When the small-sized self-balancing scooter is in a non-riding state, the pedals on the outer sides of the wheels can be turned and folded through the hinges, so that the dimension of the scooter in the length direction is greatly reduced. Therefore, the size of the small-sized self-balancing scooter is reduced, and the small-sized self-balancing scooter can be conveniently carried by riders. Meanwhile, tires of the small-sized self-balancing scooter are arranged in a splayed manner, so that the wheel diameter of the wheels is increased on the basis of ensuring the whole size of the scooter, and the obstacle crossing capacity of the scooter is improved
