Systems and methods for heating a handgrip of a vehicle. One system includes a first handgrip and a second handgrip. The first handgrip includes a first processor, a first heating element, and a first temperature sensor configured to produce a temperature signal indicative of a temperature related to the first heating element. The second handgrip includes a second processor, second heating element, and a second temperature sensor configured to produce a temperature signal indicative of a temperature related to the second heating element. The first processor is configured to receive a temperature signal from the first sensor, compare the signal to a first threshold, and adjust power supplied to the first element based on the signal. The second processor is configured to receive a second temperature signal from the second sensor, compare the signal to a second threshold, and adjust power supplied to the second element based on the signal.

A ride-on vehicle, in particular a bicycle or a three-wheel vehicle, more in particular a purely electric or pedal assist bicycle or three-wheel vehicle, including an electrically-driven air conditioning unit carried by the frame of the vehicle. An auxiliary supporting structure is connected to the frame of the vehicle, and in one example includes two rear uprights transversally spaced from each other, extending above the saddle, and continuing into two upper beams and then into two front uprights, whose lower ends are connected to a frame portion which extends in front of the handlebar. An air guiding structure is associated to the auxiliary supporting structure and is in communication with an outlet of the air conditioning unit and has one or more outlets for the flow of conditioned air, which are configured for directing jets of conditioned air towards and/or around a body of a user.

A sound and illumination device including a sound-making portion, an illumination portion, and an attachment portion for mounting on a bicycle. The sound-making portion including a lever, a spring, a striking portion, and a metal portion, wherein the metal portion covers the lever, the spring, and the striking portion. The lever may include a magnet. The illumination portion including a cover portion, an electrical circuit, a switch, a light emitting source and a power source. Actuation of the lever of the sound-making portion results in the activation of the light emitting source of the illumination portion resulting in the concurrent emission of light and sound.

A seat cover that generates heat, reflects the sun and repels water. The seat cover includes an interior side, an exterior side, and an open lower end. The open lower end can secure around a motorcycle seat and the exterior side can reflect heat and repel water. The open lower end further includes heating strips embedded in the interior side of the seat cover, which increases or decreases the temperature of the seat cover when activated by a heat control unit. The open lower end further includes a lip on the seat cover having a fastener for securing the seat cover over the seat of the motorcycle.
