This weekend will see the annual Cycle Show return to the National Exhibition Centre.

Organisers say this year's event will be the biggest yet as it has been expanded into a new hall with every part taken up by exhibitors and staging.

Sport stars such as Sir Chris Hoy and Joanna Rowsell will be appearing while dozens of well-known brands, including Boardman, Raleigh and Bianchi, are showcasing their wares.

Below is a list of five things punters can expect to see and do over the three-day event which starts on Friday:

The Stage

This will be the focal point for many of the events taking place. Among the sport stars due to appear are cycling legends Ivan Basso, Sir Chris Hoy and Jens Voigt and cycling journalist and presenter of the Tour de France coverage on ITV Ned Boulting. Various presentations such as 'A women's guide to finding cycling nirvana' and the rather scientific sounding 'The Science of Ovalised chainrings and Power' will also be held on the stage.

Davina McCall

The TV star and former host of Big Brother will  perform the official opening on Saturday morning as a guest of Beacon Bikes. McCall is becoming known as much for her charity exploits as her broadcasting and did a gruelling seven-day triathlon for Sports Relief earlier this year.

Cyclocross

A prize of £1,000 each is up for grabs at three cyclocross events on Sunday - elite men, elite women and a mixed industry race for staff from bike shops, distributors and media. The course will start and finish inside the exhibition space as well as taking in outdoor sections in the woodland part of the NEC's ground.

Mountain bike track

Visitors will able to test their biking skills and the latest models on a 1km outside track. It is designed to offer riders of all abilities the chance to go off road and test their mettle against obstacles such as rock gardens and jumps.

Something for the kids

A demo track will be in situ to let younger visitors have a crack at cycling. The area is aimed at being fun as well as educational and will allow children the chance to try out kids' bikes in a safe environment alongside qualified instructors.
