Saddle height sorted me out, i was about 1/4 inch to0 low! Have found it better to be the other way on fixed....slightly high....as BB is higher than my roadie bike. Stretch your knees - kneel down with your bum on your heals then slowly move your heals apart....allowing your bum to drop towards the floor....if it starts to hurt, stop & put a small cushion on the floor as a prop, you might (will) have tight knees (common to cyclists). Sit on this cushion, kinda between your heals for a few minutes...dont get too uncomfortable!
