A scooter includes a main body, a rear wheel mounted on a rear end of the
main body, and an operation mechanism mounted on the main body and
connected to the rear wheel to move the rear wheel. When in use, the
rider steps on the two pedals to move the scooter forward manually.
Alternatively, the scooter is moved forward automatically by operation of
the motor. Thus, the scooter is operated manually by the user's feet or
operated automatically by an electric power. In addition, the operation
mechanism is detachably mounted on the main body, thereby facilitating
the rider using and folding the scooter.
