Cycling was introduced to the program at the 1934 Games in London with three events, for men only: the 10 Mile race, the 1000 Metres Time Trial and 1000 Yard Championship.
Veteran Australian Cyclist and Olympic gold medallist Kathy Watt is seeking to claim Commonwealth Gold at age 41 in the Women's Road Race.
The 1000m Match Sprint was added four years later in Sydney and the 4000m Individual Pursuit at the next Games in Auckland in 1950.
In 1954, at Vancouver, the 100km Road Race replaced the 1000 Yard Championship and, while the distance was 120 Miles at Cardiff, Perth and Kingston, there were still five events scheduled.
The Tandem Sprint was introduced in Edinburgh in 1970, the Team Pursuit was added four years later in Christchurch while the 100km Team Time Trial came in at Brisbane in 1982, with the Tandem Sprint omitted.
Three women's events were introduced at the 1990 Auckland Games - the 100m Match Sprint, 3000m Individual Pursuit and Road Race - and the Men's 50km Points Race was also added, taking the number of events from seven to 11.
Two more women's events, the 25km Points Race and 25km Team Time Trial, were added for the Victoria Games in 1994 and there were also eight men's and five women's events at Kuala Lumpur in 1998.
In Previous Games
Mountain Biking made its Games debut at Manchester 2002, with Canadians (Chrissy Redden and Roland Green) winning both gold medals.
Of the 17 gold medals awarded in Cycling, Australia claimed 10, Canada three, New Zealand two and Scotland and Wales one each. Australia swept the medals in both the Men's road events at Manchester.
Overall, Australia won 23 Cycling medals (10 gold, 7 silver, 6 bronze), England 11 (5 silver, 6 bronze), Canada nine (3 gold, 3 silver, 3 bronze), New Zealand four (2 gold, 1 silver, 1 bronze), Wales two (1 gold, 1 silver) and Scotland two (1 gold, 1 bronze).
New Commonwealth Games records were set in every track event.
At Melbourne 2006
Track events will be contested at the Multi Purpose Venue (MPV) at Melbourne Park, road races will take place at the Royal Botanic Gardens Circuit (BOT) and St Kilda Foreshore and Beach Road, St Kilda (BRC) and Mountain Bike races will be at the State Mountain Bike Centre, Lysterfield Park (SMB).
The MPV is regarded as one of the best indoor velodromes in the world and was the venue for a very successful World Championships in 2004.
The time trail course at St Kilda is undulating and, depending on the weather and the direction of the winds on the day, could produce very fast times. The road races around the Botanical Gardens will feature one of the most technical courses ever ridden in a Commonwealth Games.
The Road Race is the longest individual competition session at the Games, with the men racing for around four hours and the women for around three hours.
The State Mountain Bike Centre has been purpose-built for the Games and competitors might see kangaroos on the course.
A total of 18 gold medals will be awarded: 12 at the track (8 men's, 4 women's), 4 on the road (2 men's, 2 women's) and Men's and Women's Cross Country in Mountain Bike.
The Keirin has been added to the track program. This is an event which features a motorised bike pacing the riders at a speed of around 50km/h until leaving the track a few laps from the end, allowing the riders to sprint to the finish.
