''I have a bit of a laugh, I know they have based the Koga a little bit on the BT, because the BT is basically the cutting edge of everything, anyway,'' Bayley said.

''I'm confident I have the best bike on the track.

''It does exactly what I want it to do, when I 'tell' it to do something, it does it it's light enough and more aerodynamic than any bike I could go out and get.

''I'm confident this bike is going to be the one that's across the line first and at the end of the day, they need it in their heads that they've got the best bikes, they're probably not going to win.''

Bayley beat Bos for the sprint gold medal at the Athens Olympics, where the Australian also won the keirin title.

The two are long-time rivals who will be among the favourites in the sprint events at the Beijing Games.

Bayley is growing in confidence ahead of the Olympics as he gains form and puts some injury problems behind him.

''Everything is working and that's all I give a shit about,''

He will receive a new Stealth in the next few days for the Olympic Games and designer Sal Sansonetti describes it as ''a beast of a bike''. Bayley agreed enthusiastically, adding: ''It is a beast of a bike, built for beastly men who are going to go out and completely flog them.'' AAP
