Chazmo,
Thank you for the followup.
Both of us have become trike-resistant! I rode mine about three miles, she about one. It's obvious for us there's a long learning curve since our bicycling reflexes seem to get in the way. Also there are places we'd like to use an ebike that won't work with a trike; offroad (slowly!) and gated access nature preserves that allow bikes but are too narrow for a trike to get through - we can walk a bike in.
We've concluded we're fine with two wheelers as long as (I think) they're significantly lighter and smaller than what we previously used which included Rad Rover 6+ and Rad Expand 5+. The Rover was a bit too tall - we toppled over standing still and at very low speed. The Expand was almost as heavy as the Rover so it became about as much work to ride it or especially to transport them.
The ONE seems to fulfill the lightness (15-20 pounds lighter) and sheds one other thing that was a bit of a distraction - shifting.
The plan is to try a
Lectric ONE since there's not an available test ride near us. If it's OK we'll get a second one.
Anyway that's the perspective at this moment - subject to change as we go forward
Tom
