a foldable support system (10) for supporting the scooter in the stationary position and an integrated command, control, monitoring, signaling and controlling the braking system (1 1 ), characterized in that said folding and portable electrically powered scooter comprises:
a single-unit composite chassis (1 );
a foldable steering column (2);
a steering column folding system (3).
2. A folding and portable electrically powered scooter according to claim 1 , characterized by the fact that, in order to reduce the size of the vehicle for storage or transport, it comprises a steering column (2) consisting of a lower steering half-column (12), a top collapsible steering half-column (13) and the steering column folding system (3) for collapsing the steering column in line with the two steering semi-column via a lower coupling (14) and a upper coupling (20).
3. A folding and portable electrically powered scooter according to claim 2, characterized by the fact that, in order to collapse the steering column, the steering column folding system (3) includes a lever (16) locked by means of a spring (19) and a bolt (15) and which, by rotation around a bolt (17), unlocks a locking bolt (18) so that the upper coupling (20) can rotate against the lower coupling (14) to achieve folding by which the sizes of the scooter are reduced for storage or transport.
4. A folding and portable electrically powered scooter according to claim 1 , characterized by the fact that, in order to reduce the size of the vehicle for storage or transport, a method of folding is initiated in a first step of the process, in a second step the handlebar (6) is folded, in a third step the steering column (2) is collapsed in a rotational way, in a fourth step the steering column (2) is fixed to the a rear wheel guard (21 ) by means of a locking system (22).
