Need cheap electric (sit down bike) or electric disabled scooter please.

One of my favorite pastimes was riding bikes with kids. No electronics, no distractions, just ride and chill. Now with spinal stenosis, one leg don't work aka can't ride bike.

Medicaid is giving giving hard time for disabled scooter. Electric sit down bikes are expensive as are disabled scooters.

Can anyone sell me one cheap? Can easily prove disability. Cash is tight. Any help would be appreciated.
