Namebio shows hoverboard.com sold for 32k two years ago. If you put up a website with some good content and start getting traffic, maybe get it to PR3, I think that it's worth a couple grand on flippa imho. The only thing I see derailing this is if hoverboards end up being a passing fad. If you google "are hoverboards a passing fad" there are some good reads. I like the name. Good luck!
