My problem is that I have terrible balance on a bike, and the last time I tried to ride one I had an anxiety attack. I still am strongly for bike usage, though.
What about an electric scooter? Or honestly tricycles with a big cargo spot on the back are pretty sweet so long as you have the space and aren’t going up any crazy hills (could get an electric tricycle thoo).
At the end of the day though, I love bicycles but they can’t work for everyone… which is why the hope for most American cities at least is in busses. I know everyone hates busses and they are usually considered the least cool thing ever but honestly they are the future for mass transit in the US. We ripped out all the streetcars which is heartbreaking but I think busses are the closest practical replacement.
If practice doesn't help, then maybe an adult tricycle could work? I remember my grandfather used to have one, and he had a debilitating muscle disease. Served him well enough.
