Just traded this

For this

I can't get the adjustment on the Jamis Citizen 1 to a point where my knees don't feel like they're too far forward of the pedals. I'm 6'2" so I have the seat al the way back and comically high. It's a 23" frame and was going to be my experiment before looking to go for a Rivendell or some thing like that. Ive always commuted on a road bike, still do with my Surly LHT, but I thought the upright thing looked like fun. It is fun, except for the weird, slightly painfull, creaky knee thing. Is it just the way these bikes ride? Is it a muscle adjustment and I just need to get through it?
