I think Biden fell off the bike because, he expected someone to grab it. He made no move to put his feet down when the momentum stopped. Watch it, like a kid who knows how do drive, but not how to park.
You need to watch it again. slojoe puts one foot down and can’t get his other shoe unclicked from the pedal. In the link above your post if you scroll down someone posted it.

There is a video somewhere that points out that Biden goes off course on that bike ride because he saw a CHILD where it wasn’t planned for him to stop. Nobody was there to catch him and he didn’t remember that he needed to put his foot down.
