Some how, I don't think you'll see mall/campus cops riding around on those...And that seems to be a majority of segway's I've seen used.Um, there is no such thing as a one wheel bike. :facepalm: Monowheel or unicycle, perhaps.
It will be interesting to see if this is a joke, or if the technology has become inexpensive enough to bring it to market. For the same price as a Seqway, I would guess they could sell at least as many units as Segway does, if the product actually exists and works. Personally, I would think that sufficiently powerful gyros would take up more room than seems to be available.
