US President Joe Biden has taken a tumble while on a bike ride with his wife Jill Biden.

Mr Biden was finishing up a ride near his Delaware beach home when he stopped to greet supporters and media.

Secret Service agents helped the 79-year-old back to his feet, where he spoke to onlookers before riding away from the incident uninjured.

Mr Biden blamed the fall on not being able to release his bike shoes from the toe cages on his pedals.
