1 THE Ferris Wheel

14 Stunning Ferris Wheels

2 The Vegas High Roller

Currently the world's highest wheel at 550ft, beating the Singapore Flyer by a scant 9ft. The passenger cabins are rotated electrically to keep them upright.

3 The Viennese Riesenrad

This is currently the oldest operating wheel in the world. It is located inside the Vienna Prater, which happens to be the world's oldest operating amusement park. Built in 1987 from a British design, by a British engineer to celebrate the Golden Jubilee of Emperor Franz Josef. At 212 ft it is nowhere near the highest wheel, but it is certainly the most historic.

4 The Tianjin Eye

A mid height wheel located in China. Also called the Tientsin Eye, it is a mid height wheel at 394ft. What makes it unusual is that it is the only major wheel that is constructed on a bridge. The Yongle Bridge over the river Hai.

5 The Osaka Wheel

An oddball as far as wheels go, the structure doesn't rotate is in a normal Ferris wheel, rather the cabins travel around a track, this allows it to be an oval shape rather than the more usual circle.

6 The Big O

Another Japanese wheel, this one is the world's largest centreless wheel at 200ft in height. It has an actual roller coaster travelling through the centre. Additionally a number of the cars have karaoke machines fitted, imagine, being stuck with someone who thinks they can sing and nowhere to escape to.

7 Baseball Ferris Wheel

Not especially large as wheels go, but certainly distinctive, based in Comerica park in Detroit, home to the Detroit Tigers Major League Baseball team, the cars are obviously baseballs.

8 The Waggon Wheel

Located in Flamingo Land U.K. Themed around the classic plains wagons of old America. One for all the cowboys out there, and boy we know a few.

9 The Golden Reel

Located in the gambling city of Macau, this is one of the highest wheel's around. Not due to the size of it's construction, but in view of the fact that it is built into the side of two hotel complexes. You board on the 23rd floor and it is a figure 8 wheel.

10 Royal Tires Wheel

The Uniroyal wheel, created for the 1964 New York World's Fair. Although a baby at only 80ft high, it was designed by the same architects as the Empire State Building. Driven by a 100hp engne it can carry 96 passengers.

11 John Kormeling Wheel

A total one off this, created by the artist John Kormeling, it doesn't have passenger cabins. Instead it has a number of platforms that you actually drive your car onto. The cars then rotate on the wheel.

12 Priyat Wheel

This is one hot wheel. Not due to it's construction, but more to do with the fact that it is situated near to Chernobyl. The town famous for having one of the world's worst nuclear disasters. Abandoned before it went into operation.

13 Eccentric Wheel

Although not totally unique, it is nevertheless uncommon. Instead of the cars being attached to the outer rim, they tracel on an inner track, so they move towards the centre of the wheel and back as it rotates. One was built for Coney Island in 1920, another for one of the Disney parks.

14 Underground Wheel

A mere 65ft high, what makes this unusual, is the fact that it is actually underground, inside a giant salt mine. Located in Romania, the mine dates back to the 13th Century and is 368ft below ground, making this the lowest wheel in the world.
