A bicycle control device includes a body, at least one button on the body, an antenna for connection via radio to a component of the bicycle, and an electronic unit mounted in the body and connected to the button and to the antenna. The control device also includes an insert made of electrically insulating material, with a resistivity greater than 10.sup.7 Ωm, on the body, the antenna being on the insert. The arrangement of the antenna on the insert of such an insulating material reduces or eliminates disturbances during the transmission from the antenna to the component, independently of the material of the body.

Disclosed is a carry-on including a substantially rectangular parallelepiped container with a handle extendable from the container from an upper base thereof. The carry-on also includes a telescopic platform extendable from the lower base of the container and including wheels at which the carry-on may rest on the ground. The platform is motorized using actuators capable of rotating two of the wheels about a respective transverse axis thereof. The platform includes sensors suitable for detecting a movement of the center of gravity of a user of the carry-on when the user is standing on the platform. A control unit is suitable for controlling an actuation of the actuators according to the movements of the center of gravity of the user detected by the sensors. This results in the carry-on being drivable by a person standing on the platform by slight movements of the center of gravity thereof.
