For what it's worth, I upvoted the 'story' because I never heard of such a thing and it looks really cool. While I'm a little sad to read that this kind of thing doesn't actually really help, it's not that unexpected. Still, it looks neat, and once the price comes down (I didn't see any prices but I'm guessing it's hundreds for a few metal parts), I might want to play around with such a bike to see for myself. It's a little like other gadgets/gimmicks. (Some gadgets have use, others don't really.)
