Thanks, all. He loves his recumbant trike (which is similar to the Anura), but it's a major production to go for a ride. Two people are needed to haul him up from the bike, and to get the bike into the car, etc. I'm hoping to find something light and stable that he can use for everyday mobility--around the house, , shopping, going out downtown. Right now, because he hates the thought of a wheelchair, he's essentially confined to his house unless we can get him into the big recumbant trike.
