The designs for London 2012's velodrome have been unveiled by the Olympic Delivery Authority (ODA).

The VeloPark, as it will be known, was designed by Hopkins Architects – with Expedition Engineering, BDSP and Grant Associates – and will be based to the north of the Olympic Park.

The facility will include a 6,000-seat velodrome for the indoor track cycling events and a BMX circuit. After the Games, a road cycle circuit and mountain bike course will be added to create a cycling hub as part of the Olympic legacy plans.

Mike Taylor, a director at Hopkins, said: "Our vision for the VeloPark has always been to create a place where both beginners and elite athletes will be equally at home. The form of the velodrome has been designed to express the drama and elegance of the track geometry and we hope it will become one of the defining images of the Olympic Park."

Chris Hoy, the British cyclist who won three gold medals at this summer's Beijing Games, was there at the unveiling of the plans.

"Winning gold in Beijing was an unbelievable experience, so it's great to come to London to visit the site where I hope Team GB will win a lot more gold medals in 2012," he said. "Becoming Olympic champion simply wouldn't have been possible without the local cycling facilities I used when I was growing up, so I'm delighted to help launch the designs of the London 2012 VeloPark.

David Higgins, chief executive of the ODA, said: "As the latest designs show, the VeloPark will be one of the biggest legacies of the Olympic Games, delivering world-class facilities for cyclists of all ages and abilities to use for years to come. The velodrome is a striking piece of architecture for the Olympic Park, and together with the wider cycling facilities to be built after the Games, this will be a landmark new venue for London."
