Abstract: A scooter includes a frame body, a handle unit, and a wheel unit. The frame body includes a main member formed with an accommodating space, a seat-connecting rod, and a front member connected to a front end of the main member. The seat-connecting rod has a front end connected to the main member. The seat-connecting rod is pivotable relative to the main member between a retracted position to be accommodated in the accommodating space, and an expanded position, where a rear end of the seat-connecting rod is away from the accommodating space for being coupled to a seat. The handle unit includes a front fork connected to the front member. The wheel unit includes a front wheel mounted to the front fork, and at least one rear wheel mounted to the main member.
