I thought it might be a K2 T-Nine model, too, because I saw their Trailhead model at REI a few weeks ago and it has a really cool subtle flower pattern, as well. I am not much for flowers on bikes, but I was ready to trade in my Rockhopper on the spot. That one is green, but I thought maybe they had a hybrid in the yellow.

It's really the brown saddle and handlebar grips that are throwing me.
