Solowheel - a Seguelike unicycle

My email this morning had this link from Grist about a staffer trying out the Solowheel.  Go see the video here.  This seems fun and compared to an electric bike price, very reasonable in cost.  I'd just want to know how to stop it before I bought one since the staffer seemed to have trouble with that issue.  Jumping off does work but, like on a bike, that's not always the safest way to dismount.

The Solowheel is local to Seattle and there are other, less expensive alternatives.  Here's a second look at one of those, the Airwheel.

Guess it's time to sell the electric scooter that has the same range but weighs over 200 lbs...
