Vehicle

Vehicles are physical craft created or appropriated for the purpose of transporting people from one place to another.

Ships
Ships are the most common vehicle seen in the world due to its high oceanic concentration. Ships can range from small rowboats and rafts to massive dreadnoughts that rival even islands in size. The island of Thriller Bark was converted into a massive ship, and Water 7's administration plans to do the same for their town. The Germa Kingdom is based entirely on a fleet of large ships that can link together. Pirate ships are commonly seen on the seas in the Great Age of Pirates, and the Marines command a massive fleet of battleships to oppose them.

Most ships are piloted through the water by rowing or sailing, with a few advanced ships being powered by engines. In Skypiea, another form of seacraft power known as the Dials is used; after taking in a sufficient amount of wind, it can release the wind on command to help ships move across the sea, and works in both the White Sea and the Blue Sea. They are often used to power Wavers, a craft that is predominantly used in the Sky Islands which resembles a scooter. Submarines also exist, like the Polar Tang and Shark Submerge III, that enable riders to travel underwater.

Steeds
Animal steeds are a common form of land transportation in much of the world that lacks advanced transportation technology, although some steeds are also capable of traveling through water and even the air. Certain animal species have been largely domesticated by people to carry them, and ultimately a large variety of animals have been shown to be used for transportation once a person manages to tame them.

Bikes
Bikes are a rarely seen vehicle. Kuzan has a manually-powered pedal bike known as the Ao Chari, which he uses in conjunction with his Hie Hie no Mi powers to ride on the frozen ocean. Additionally, Smoker has his Billower Bike, a three-wheeled motorbike that is powered by the smoke he generates with the Moku Moku no Mi. Franky also built a motorcycle known as the Kurosai FR-U IV while on Karakuri Island.

Trains
The only known train in the world is the Sea Train, a steam-powered boxcar train that runs on a set of rails which float freely in the ocean, lurking centimeters below its surface. The Sea Train was conceived and built by the shipwright Tom of Water 7's Galley-La Company, who designed it to connect Water 7 with several neighboring islands including the World Government judicial island Enies Lobby.

Aircraft
There are few non-sentient forms of flying transportation that have been seen so far, with those that have been seen all being powered by Devil Fruits. These include the Ark Maxim that is powered by the Goro Goro no Mi's electricity, the Flying Gas Balloon powered by the Gasu Gasu no Mi, and the non-canon Island Ship which is a large landmass levitated by the Fuwa Fuwa no Mi. Additionally, Fujitora has been seen using his Zushi Zushi no Mi to commandeer a flying Marine battleship.

Miscellaneous Vehicles

 * Bon Chari are special bubbles that are outfitted for people to ride on the Sabaody Archipelago. People ride them by operating pedals that make a propeller spin and push the craft forward. They are only found on Sabaody, as the bubbles pop outside of its environment.
 * The Brachio Tank V is a tank built by Franky on Karakuri Island. It is a large vehicle that moves on land with its treads.
