OneWheel is a great travelling companion. It works much like a segway, but with one wheel. It has a small gyro and a motor that can get you to a 7 miles long evening travel. The battery loads in about 4 hours and it costs $1500 if you preorder now.
While it is not cheap[, if you have some spare cash and want to spend it on something cool, then OneWheel is a great way to do that. Gotta get one for me sometimes 😀
