The invention is directed to an inertial sensor attachment structure including: a floating bracket which is fixed to a vehicle body frame via a vibration absorbing member; an inertial sensor attached to a first attachment surface of the floating bracket; and an ABS unit attached to a second attachment surface of the floating bracket.

A bicycle seat suspension can include one or more movable body members. The one or more movable body members can be configured to be operatively connected to a bicycle saddle. The one or more movable body members can be configured to change configuration when a load is applied to the bicycle saddle. The bicycle seat suspension can also include a vibration isolator. The vibration isolator can be configured to exhibit a non-linear stiffness profile including a region of quasi-zero stiffness. The vibration isolator can be operatively positioned such that, when the one or more movable body members change configuration responsive to a load being applied to the bicycle saddle, the one or more movable body members can engage the vibration isolator. As a result, the vibration isolator can isolate a person seated on the bicycle saddle from vibrations transferred through the bicycle saddle.

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.
