Segway One S1 Personal TransporterGear
This Segway takes a little more skill to master than the original Segway PT. The S1 is self balancing and has a lithium-ion battery, that gives you a range of 15 miles with a single charge. It goes up to 12.5 MPH. You can control the speed using a smartphone app. From this app, you can also set it in transport mode or carry mode so it becomes more lightweight.
