And I got it to move. I was worried because I read a ton of "I can't get this thing to move at all, what am I doing wrong?" on Trikke forums and blog posts, but part of it is not unlike being on a motorcycle--as long as you're not afraid to lean, you can make it go. To turn on a motorcycle, you have to lean; forward movement on this, you have to lean.
But dang, it is a full body workout...just what I needed, to be sure. I think I have a favorite new toy, after the Spouse Thingy and my scooter.
