The guy on the video says the range is 25 miles. According to another text review, the range is 15 miles. The older model had a range of 10 miles, so I'm guessing the new model has a range in the 10-20 mile bracket. They run on NiMH batteries.
I still haven't seen one working but from being on a normal scooter before, I'm sure the ride is fine.
At $400 each, they definitely make more financial sense than buying a Segway.
