I agree, there are zippy trikes out there that are easy to get on and off. The Catrike Villager is one, with a higher seat and plenty of gearing to keep it 'zippy' but the new price is around $2500. I know of a shop here in South Florida (Vite) has a demo for sale for a solid $2000, or they did a few weeks ago. The Rover is a nice trike, but kind of heavy and most of them have a maximum of 8 speeds as they use IGH's. My wife rides one, and I want to get her into a Villager similar to mine.
