See you when you come by to get the seat. The problem isn't that the seat won't go too low, it's that, if you fit the bike perfectly to the knees, it's up too high. The higher the BB goes off the ground the higher the seat goes. Also problematic, the shorter the crank arm, the higher the seat has to go. So either you bust your knees or ride on stilts.
Thus, as it stands, the bike is oddly proportioned, with tall folks having a short reach and short folks sitting in the stratosphere.
I hope that all this criticism is constructive, I think it's a great bike.
