Thanks to all who have posted for the encouragement and suggestions. The recumbent trike seems like a winner to me. I have a small SUV that I think it will actually fit into when I want to go the the beaches near Los Angeles (about 130 miles from where I live in Bakersfield). Just gotta keep pumping iron at the gym so I can lift the 50 lb weight into the car.

My reconstructed knees are extremely sensitive to pain, which adds to my fear of falling. The trike configuration helps to eliminate that problem/fear.

I am excited about this option and shall do more research into trikes. Thanks, Mom On Bike, for the link.
