Video footage of the incident shows Biden crossing a street at low speed, before putting one foot down on the asphalt as if to dismount his bike. Instead, the president fell to the ground, landing on his side.

Biden, who was wearing a helmet, was helped to his feet by assistants. He rode away after speaking briefly to the small crowd of supporters who had gathered along his bike route.

According to the White House, Biden fell after his “foot got caught on the pedal,” and did not need medical attention.

Biden has often been seen cycling around the beachside town of Rehoboth. During his 2020 election campaign, Biden’s supporters pointed to these bike rides as evidence of the former vice president’s vigor, amid attacks by incumbent President Donald Trump about his mental and physical health.
