Abstract
An electric kick scooter, of a type uncommonly stable and easy-to-handle, comprising two back wheels supported by a tilting cross member; and an intermediate support hinged to the frame through a first hinge with a first hinging axis (X) parallel to a rotation axis (Z) of the back wheels; the tilting cross member being hinged to the intermediate support through a second hinge with second hinging axis (Y) orthogonal to the rotation axis (Z) of the back wheels, the first and/or the second hinge being made as a fixed profile introduced in a hollow profile with interposition of elastic blocks.

An electric kick scooter comprising:
- a footboard for bearing a user;
- a front wheel handled by a handlebar through a fork stem;
- two back wheels supported by a tilting cross member;

- and an intermediate support hinged to the footboard through a first hinge with a first hinging axis parallel to a rotation axis of the back wheels;
- the tilting cross member being hinged to the intermediate support through a second hinge with a second hinging axis orthogonal to the rotation axis of the back wheels;
- wherein at least one between said first hinge and said second hinge comprises:
- a housing;
- an inner profile inserted in said housing;
