Not mine, lucky me.
While not my thing either, there isn't anything wrong with those bikes. The auto-shifting mechanism is a little finiky, I've heard, but that's what the plastic weights are - it uses centripital force to change gears, I assume using a low normal rear derailleur.
And the second triangle should make the frame stiffer at the expense of weight.
