a board intended to support a user while standing; said board comprising a first platform and a second platform;

fastenings fixed to the board;

wheels rotatably mounted in the fastenings in order to move the board;

a first frame fixed to the first platform and a second frame fixed to the second platform; and

connection means rotatably connecting said first frame to said second frame in such manner that said skateboard can be in an open position, in which the first platform and the second platform are aligned and coplanar, and in a closed position, in which the first platform and the second platform are parallel and disposed on different planes;

wherein

said skateboard comprises a cursor fixed to said second platform; and

said second frame comprises a track for said cursor to slide along a longitudinal axis of the second frame in such manner that said second platform slides from a proximal position with respect to said first platform to a distal position with respect to said first platform.

2. The skateboard of claim 1 , wherein said connection means comprise at least one rod hinged in said first frame and in said second frame in such manner to rotate when the skateboard passes from the closed position to the open position.

3. The skateboard of claim 1 , also comprising:

locking means to lock the rotation of said first frame with respect to the second frame when the skateboard reaches the open position.

4. The skateboard of claim 3 , wherein said locking means comprise a striker provided in said first frame that is engaged in a seat provided in said second frame to fasten said second frame to said first frame when the skateboard reaches the open position.

5. The skateboard claim 1 , wherein said first frame comprises lateral seats that are open on the bottom to house the wheels connected under the second platform when the skateboard is in the closed position.

6. The skateboard of claim 1 , comprising second locking means to lock the sliding of said second platform when the second platform is in a position proximal with respect to said first platform or in distal position with respect to said first platform.

7. The skateboard of claim 6 , wherein said second locking means comprise a pin or a spring-loaded ball connected to said cursor that is engaged in a distal seat provided on said track in distal position with respect to the first platform and in a proximal seat provided on said track in proximal position with respect to the first platform.

8. The skateboard of claim 1 , comprising an electric motor connected to a wheel.

9. The skateboard of claim 8 , wherein said first frame is a box structure comprising a compartment adapted to house a battery for powering the electric motor, said compartment being closed by said first platform.
