I have a cloud 9 Cruiser select seat on my e-bike, but my unpadded rear still gets sore after about 10 or 15 miles. It was okay at first, then I change the angle of the seat to a more angled up setting, but now have put it back hoping that will ease the discomfort a bit. Don't have much padding back there on my body, so I'm a bit sensitive to those type of adjustments.
