It is totally like what someone said above - when you first get on the bike, tons of weight (well, maybe not "tons"!!) is on your sit bones. But then when you get going, you shift your weight forward a bit to get the weight of your hips over your pedals, then, as you really get going, you are just lightly perched on/over the saddle with most of your weight on (and through) your legs for maximal power on the downstroke.

The only time that this isn't true (for me, anyway) is at the end of a long ride and/or when fatigue starts to set in. Then weight naturally shifts back to the sit bones and my bum starts hurting again - need to make a conscious effort sometimes not to let that happen :-)
