The Ferris wheel is a large outdoor amusement ride, with passengers riding in cabins that hang from the edge of the wheel. As the wheel slowly turns upwards, passengers can take in the surrounding scenery from a high vantage point.

The appearance of Ferris wheel is wheel-shaped, like large disc-shaped amusement-type facilities. At the same time with many beautiful lights, at nightfall, very spectacular.

The Ferris wheel is popular with children, although it is also a high-altitude amusement facility, but is not as intense as the jumping machine, and is also a good dating place for couples, who like to ride the Ferris wheel together, which is also the heart of many girls' small desire.

The most common Ferris wheel generally appears in amusement parks (or theme parks) and park tours, as a kind of playground motorized games, and roller coasters, carousels are collectively known as the "three treasures of the park". But the Ferris wheel also often exists alone on other occasions, usually as an event observation deck.

According to the difference in the operation mechanism, the Ferris wheel can be divided into three kinds: Ferris Wheel, spokeless Ferris wheel, and Observation Wheel.

The cockpit of the gravity Ferris wheel is suspended on the wheel, and the level of the axle is maintained by gravity. The cockpit on the Observation Wheel is hung outside the wheel and requires a more complex linkage-like mechanical structure to synchronize with the position of the carriage to maintain its level.

The earliest Ferris wheel was designed by the American George Washington Ferris in 1893 for the Columbian Exposition in Chicago to compete with the Eiffel Tower built in Paris for the 1889 Exposition.

The first Ferris wheel weighed 2,200 tons, could take 2,160 people, and was equal in height to a 26-story building. Because of Ferris's achievement, it was later called the "Ferris Wheel," or the Ferris Wheel as we know it.

The Vienna Flyer is one of the surviving 19th-century Ferris wheels that are still in operation today. It was erected in 1897 at the Prater amusement park in Leopold City (second district) of Vienna, Austria.

After the demolition of the Paris Flyer in 1920, the Vienna Flyer became the world's tallest Ferris wheel, which burned down in 1944 and was rebuilt the following year, retaining its status as the world's tallest Ferris wheel. Until 1985 when it was surpassed by Tsukuba, Japan (85 meters high).
