A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.

An integrated control device is provided, having a support body configured for attachment to curved bicycle handlebars. The support body has a brake lever for controlling the brake, and a pair of control levers. The pair of control levers are configured for manual operation. Each control lever has a respective control region and the control regions of the pair of control levers are arranged behind the brake lever and above each other.

A bicycle electronic controller has a body with a push-operated switch, a manual actuation member for issuing a command, and a motion transmission device interposed between the manual actuation member and the switch. The motion transmission device includes a guide element which is provided with a filiform through cavity and has a first end fixed in proximity to the manual actuation member and a second end fixed in proximity to the switch. A longitudinally, substantially incompressible filiform body is slidingly guided within the guide element and has a first end pushed by actuation of the manual actuation member and a second end that pushes on the switch. The switch is housed within the electronic controller body where a tight insulation can be achieved in addition to arranging the actuation member where it is more ergonomic.

A bicycle electronic control device having a support body configured for attachment to the bicycle handlebars. The control device includes a switch and a manual actuator for switching the switch and issuing a command. A de-coupling mechanism is interposed between the manual actuator and the switch for initially de-coupling the manual actuator from the switch.

A bicycle wireless control device has a support body that attaches to a bicycle. The support body houses a plurality of electric-electronic devices including a wireless communication module on a printed circuit board (PCB). A coaxial cable extends from the PCB to an outer surface of the support body and functions as an antenna.

A bicycle electronic controller has a support body that attaches to the bicycle's handlebar. A plurality of electric-electronic devices are housed within the support body on printed circuit boards (PCBs). Two of the PCBs are parallel to each other, and spaced from each other, and electrically connected to each other.

A hydraulic disc braking system is disclosed. The system has a manually operated control device for a cyclist to issue a braking command. The system has a master cylinder assembly having a membrane dividing the hydraulic fluid tank into a variable volume filled chamber and a complementarily variable volume empty chamber. A membrane detector senses the presence of the membrane relative to a predetermined position in the tank and/or a meter measures the distance of the membrane from the ceiling of tank.

A diagnostic method for a bicycle hydraulic disc braking system, having a master cylinder assembly with a cylinder inside which a piston reciprocates against the action of a return spring. The master cylinder has a hydraulic tank with a bottom, a ceiling, and a membrane that divides the hydraulic tank into two chambers. The hydraulic tank is connected to the cylinder through the bottom. A metering device measures the distance between the membrane and the ceiling of the tank. The output signal of the metering device is evaluated to determine that operation is correct when the membrane temporarily approaches the ceiling by a predetermined extent range, or incorrect otherwise. A positive evaluation reflects the correct operating condition, and a negative evaluation reflects an incorrect operating condition.

A control device for a bicycle has a housing configured to be mountable to the bicycle and sized and shaped to be grasped by a user's hand and a battery receptacle positioned on the housing. The housing has a base portion and an extension portion. The base portion includes first and second ends, a downward facing side, an upward facing side, an inward facing side, an outward facing side, and a handlebar clamp disposed at the first end. A battery receptacle is positioned on a first side, which can be the downward facing side, of the base portion of the housing. An accessory port can be positioned on a second side of the base portion of the housing, different from the first side, and which can be the inward or outward facing side of the base portion of the housing.
