Voit Gravity Rider?
 

My husband saw an ad for one for sale (used) and wondered if it's something that would interest me....

But I don't know a thing about it. A quick google search tells me that it SEEMS to be like an elliptical, but bike-style.

Does anyone have any info/input on a "Gravity Rider"? I don't want to waste money on something that's "snake oil", but would love a work out method at home since I live far from the gym.

Anything...anything at all!
