welcome.
Do you feel like your sliding forward on your seat? and use your arms/hands to hold you up? if so then your seat is pointed down to much.
btw i love my cruiser, but what is a small bump in the road the cruiser makes it a full on mountian. Whereas my road bike doesnt even know the road turned up for a bit. now on rough roads and crappy urban streets the road bike rattles the fillings out, whereas the cruiser is buttery smooth over the worst potholes.
