I ride a Gary Fisher mountain bike and it weights in about 27 pounds with my crankset, clipless pedals, under seat bag, etc. This thing has taken an absolute beating and keeps right on going.
My Cannondale road bike on the other hand weights about 18 pounds with my gear. It's noticeably lighter when you pick it up. Most people who aren't into bikes are astounded with how light it its...not like the old heavy frame 10 speeds of our childhood.
But I think your point is very valid for the very low end bikes...they will all be using steel frames and such and this will increase weight substantially. Both of my bikes were entry level models in each class, but my mnt bike was about $600 and my road bike was around $1,000.
