The precocious 21-year-old will now run in his favoured event, the 200m, with even more confidence.
"I was trying to see if I could take all the rounds," Bolt said after his 100m triumph.
"I've shown I can take it so I'm going to run the 200m.
"I'm not really worried about world records," he added. "I'm just coming here to win. That's the aim for me."
Over the longer sprint, Bolt is unbeaten and possesses the three fastest times in the world this year.
His 19.67sec time in Athens propelled him to fifth on the all-time lists and his victories in London (19.76) and Ostrava (19.83) were similarly impressive.
In those runs and as was clear in his 100m performance at the Beijing Games, Bolt seems to hold some in reserve, which also raises the prospect of him being a real challenge to American Michael Johnson's world record of 19.32sec, set at the 1996 Atlanta Games.Bolt's main rival will likely be American Walter Dix, the bronze medallist in the 100m who beat defending Olympic champion Shawn Crawford at the US trials at 19.86sec and recorded a personal best of 19.69sec last season.
"I'm going to get ready for the 200m," said Dix after setting a personal best of 9.91sec in the 100m.
"I'm quite proud of the result but I know I have much more to do."
Crawford, who beat drugs-tainted compatriot Justin Gatlin to 200m gold in the Athens Games four years ago, has not shone on the international stage since, but has recently hit some good form.
American teammate Wallace Spearmon, who has won a 2005 silver and a 2007 bronze medal in the event and finished 0.04sec behind Dix and Crawford at the US trials, could also be among the contenders for a podium placing.
Among other potential rivals are Churandy Martina of the Dutch Antilles, who impressed in finishing fourth in the 100m at 9.93sec.
Martina said his performances in the 100m had given him heart.
"I improved my personal best three times and there's no better place to do that than right here."
The heats for the 200m are scheduled to take place on Monday morning with the quarter-finals later that evening. The semi-finals take place a day later and the final on Wednesday at 10.20pm.
