Pros: lots of pickup, solid top speed
I was fortunate to be able to take a spin on Dana1981's RMartin over the weekend and had a blast on it.
After going around the block a few times with a huge smile on my face, Dana asked me to pull off so he could check some settings. As it turns out, there is some sort of energy saving mode that makes the acceleration much slower and apparently I had been stuck in that mode. Even so, one of my first comments had been how responsive and peppy it felt.
Out of nerd mode and into turbo, I was definitely in for a great ride. The first few turns on the throttle caught me a little off guard because it really gets up and goes. I would feel very comfortable on any surface street crusing around on that thing (top speed around 50.)
The other really striking thing is the silence. I have ridden (and loved) gas powered scooters in the past because of how in touch you are with your surroundings, unencumbered by 4 doors and glass everywhere. But this is another level, you get all that, but with the added benefit of no whiny engine noise and bad fumes.
I'll definitely be looking in one of these in the future.
