Triple Beijing gold medal-winning cyclist Chris Hoy has helped unveil plans for the VeloPark for London's 2012 Olympic Games.
The VeloPark will include a 6,000-seat velodrome to host the cycling events as well as a BMX circuit.
After the games, a road cycle circuit and mountain bike course will be added, so the park can be used by everyone.
A planning application will be submitted later this month with construction work due to start in 2009.
The VeloPark designs have been developed following consultation with British Cycling and local cycling groups.

After the games, the park will be linked into cycle routes across London, connecting the whole of the city with the new facilities.
Hoy 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 which will provide first-class facilities for cyclists of all ages and abilities".
Olympics minister Tessa Jowell added: "The designs meet the challenging brief to provide not only a first-class games venue, but also a springboard in legacy for future British Olympians and will make a valuable contribution to increasing sport participation from grassroots to elite level."
The launch of the latest plans for the London 2012 VeloPark follows the opening of the Redbridge Cycling Centre last month.
The £4.5m facility was built by the London Development Agency (LDA) for community and competition use to replace the former Eastway Cycle Circuit which made way for the site of the London 2012 VeloPark.
Hoy was joined by Locog chairman Lord Coe and London Mayor Boris Johnson for the unveiling of the plans.
