The Big Wheel at Belfast City Hall is proving a huge hit with the public in its first week of operation.
And the company that runs it, World Tourist Attractions, hope to have an even bigger one in the city in the future.
Since Sunday locals and tourists alike have been going up in the wheel to get panoramic views of the city, Belfast Lough and the mountains and hills that surround it.
John Lowery, senior manager with WTA, said it had been trying to bring the Big Wheel - the largest transportable observation wheel in the world - to Belfast for three years.
"This wheel is brand new. It has just come from the manufacturers. It is 60 metres high and weighs 365 tonnes. It arrived on 29 containers it took two weeks to assemble, which was a big logistical task, but we have done it on time.
"We are currently developing a larger one. We want to bring an 80-metre high wheel to the cities - and hopefully one day that will include Belfast," he said.
John said the wheel is currently under contract to stay in Belfast until March - but that negotiations are under way with the City Council in a bid to extend that to 12 months.
John said the response had been 'magnificent'.
"People were queuing on Sunday, the first day it was running, and we've had a steady stream of people all week.
"Online ticket sales didn't start until the weekend and we have sold more online tickets than we have done anywhere else - so we expect a busy weekend coming up."
The capsules will soon have commentary explaining the sights around the city.
John explained: "There's a panic system so if someone does get frightened they can press a button and speak to the controller and they will be taken straight off the wheel.
"But it's a very smooth ride and people are normally okay.
"There's also a VIP capsule which has a glass floor, a DVD player, leather seats - even champagne."
