US President, Joe Biden Falls While Riding His Bicycle (Photos)

Joe Biden, the President of the United States fell off his bike in Delaware as he celebrated his 45th wedding anniversary on a weekend away with wife Jill.

He took a tumble when he tried to get off his bike at the end of a ride on Saturday at Cape Henlopen State Park near his beach home in the US state, but insisted he was not hurt.

"I'm good," he told reporters after US Secret Service Agents quickly helped him up.

"I got my foot caught in the toe cages."

The 79-year-old leader and first lady Jill Biden were finishing a morning ride when the president decided to pedal over to a crowd of well-wishers standing by the bike trail.

But he fell to the ground when trying to dismount, which was met with gasps by shocked onlookers.

Several security agents rushed to his aid after the fall, which took place on a trail at Gordons Pond.

The president quickly collected himself and spent several minutes chatting with people who had gathered to watch him cycle.

Earlier, he had breezed past members of the press after setting off - unaccompanied by the first lady - and said "Good morning!" with a wave.

He and Jill have been spending a long weekend at their Rehoboth Beach home after marking their 45th wedding anniversary on Friday.

The couple are understood to be keen cyclists and often go for rides around Delaware.
