One thing that would have to be changed to make a moon-roving segway possible is the tires/wheels. The air-filled tires would literally explode in the vacuum of space.
Tweels may be perfect for this application!

Sorry, I just can't help it...
The difference in pressure from the Earth (sea level) to the Moon is about 14.7 psi. So that much more force would be pushing out on the tires while on the moon - since it isn't countered by any atmospheric pressure. However, in the extreme cold of space the tires' air pressure would be significantly reduced.
18 psi in the tire on earth would be equal to 32.7 psi on the Moon - before taking into account the colder temperature.
I wonder how those silicone tires and plastic wheels would hold up in the coldness of space...
Yeah, I think something like tweels would be better.
