The Segway is so 2001.

Thankfully, Inventist Inc has taken the concept of the Segway one step further with the Solowheel. Instead of a two-wheeled, self-balancing vehicle, the Solowheel has only one wheel as its name implies. 

This video explaining the invention that can only be described as a 21st century version of the unicycle is from last July, but has only gone viral now.
