Thank you for that link. But unfortunately no kick scooter would work for me. The mind is willing, but the hip is not.
And I’m not looking for an electric scooter, as it takes away the exercise benefit. Thanks anyway!
This is probably the closest to what you want:

A wheel chair is about as close as you are going to get unless you build one yourself, or hire a bike builder to do it. They TIG weld custom frames all the time. Where your problem will be is steering while propelling it.
