US President Joe Biden falls off his bike 

Biden says 'I'm good' after taking a tumble from his bike in Rehoboth Beach, Delaware

He was biking with First Lady Jill Biden in a state park near their beach home in Rehoboth Beach, Delaware and had stopped to talk to onlookers when he fell.

The president told a small crowd of well-wishers and reporters that he had lost his balance as he tried to pull a foot out of a bike clip.

The result: "a mad scramble of Secret Service and press," a White House pool report said, adding there were no visible scrapes or bruises from the fall.

"No medical attention is needed," a White House official said. "The President looks forward to spending the rest of the day with his family."

As the oldest US president, Biden's health is the subject of constant attention, particularly as speculation rises on whether he will seek a second term in 2024.

In November 2020, shortly after his election but before taking office, Biden broke a foot while playing with his pet German shepherds.
