‘I’m good,’ the president told the press who saw him take the tumble, which transpired around 9:30am.
Biden told reporters that he had trouble removing his shoes from the bikes’ pedals, causing the fall.
He had come over to say hello to a crowd that had gathered near the Gordon’s Pond State Park bike trail, with people yelling ‘Happy Father’s Day’ to the president.
Upon trying to dismount the bike, his shoes caught and he fell over sideways, causing a mad scramble of Secret Service and press trying to help him up.
Gasps rang out after the fall, which saw Biden, 79, stay on the ground for roughly 10 seconds, before being helped up by several Secret Service Agents, who immediately swarmed the downed Democrat.
Moments later, Biden was glad-handing the crowd – even bringing one woman out to meet first dog Commander, who was being walked nearby.
Despite the tumble, the president – who donned shorts and a T-shirt for the excursion – did not appear to suffer any abrasions or cuts from the spill.
First Lady Jill Biden, who joined her husband after his initial loop by reporters, missed the fall, after zooming on ahead of the head of state.
