Yes. It was stupid to give him a bike with those pedals.
Tripping and falling down, is not that big of a deal. Especially at that age.
The point though, is that he or his handles though that showing him biking would help deal with concerns about his age and... state.
They thought he was capable of a small bike ride.
I hope they gave some consideration to the possibility of failure. Because they did fail.
He should be exercising, In a controlled environment with no danger of falling.
He is elderly and frail. And likely not all there. I am fine with him staying. A potted plant would be a better president than his vp.
He needs to demonstrate real.... something before he runs again, or he should not run.
