Biden's bike may or may not have training wheels, but I can tell you with great certainty, he is no cyclist, and neither are the other clowns riding with him. Anyone that is a serious cyclist wears a helmet. That is usually something they don't leave home without. I know too many folks that have had head injuries, and I have seen my share of dumps, with guys going down very hard.
All those pictured above are clowns. It was not a serious exercise effort, just a photo op. Shallow Joe and team!!!!
