Video: Arenacross comes to The O2
Motocross stars including former world champion Andre Villa and carried out stunning backflips by The O2 to advertise this Saturday's dramatic activities at the North Greenwich venue.
The Arenacross event will where riders attempt daring jumps at speeds of up to 50mph under the big roof.
As well as Villa, European star Edgar Torrenteras from Spain, will also be in attendance.
And 26-year-old Londoner Dave Wiggins - fast becoming known as the wild child of the sport - is also there, as well as a host of up and comers tipped to be the next big think in UK dirt bike racing.
Called Arenacross - a concept founded in America in the '70s - the show is a mix of professional motocross racing and freestyle motocross. First conceived in America, the programme takes place on a purpose-built track.
Riders race over huge jumps and fast-banking corners, while in the freestyle section they become gymnasts on bikes, performing feats such as backflipping a 100kg machine 40 feet above the ground.
Matt Bates, managing director of promoter E22 Sports, said: "I can't wait to bring Arenacross to The O2.
"London is such a vibrant, exciting, colourful city and Arenacross is such a vibrant, exciting, colourful sport.
"It's a perfect match."
