I have taken a hiatus lately due to a move and other factors. In the past I have heavily criticized Segway vehicles (or similar) for providing motorized transportation for the average person in light of the obesity problem in the U.S. and other industrialized nations.
Now here is a suitable replacement that requires your movement and on the flats is probably as fast as a motorized Segway. You can still be outside, get much needed physical activity, and travel a reasonable distance.
Now I haven’t test-driven this machine and like everything else in life it has some shortcomings: not aerodynamic, heavy to carry up stairs, too large to keep in an office or small area, a high center of gravity (which could? cause some stability/safety issues), and cost.
But it is certainly worth taking a look at or at least taking a test drive.
