At Interbike this year, there were plenty of bikes with electric assist, and a few that seemed to be all-out electric scooters. And then there was the SBU. It's a self-balancing unicycle. Those are footrests, not pedals. To go forward, lean forward. I guess you lean back to stop. It's like a Segway for people with balance. It's definitely not a bike by any stretch of the imagination, but as far as distribution goes, bike shops would be the most logical choice. Oh, it weighs almost 25 pounds, and sells for about $1,500. So, which is it?
