OK, so I not quite sure why I would need to get one of these, but I want one! 8-)
The prototype SegVator SegTrax --- the *all* terrain mod for your Segway, go where you couldn't/wouldn't before! SeVator have come up all sorts of good stuff for the Segway, including the SegPlow for those colder climates.
I'd like to know how far you could actually go with the standard Lithium-Ion battery packs. Pr does it have a different power source?
