maybe, to some extent, trying to get your 30lb bike going just as fast will be more tiring. A 30lb road bike? Sounds like a touring bike. My touring bike was in no way more tiring unless I tried to get that thing to 20mph because that kind of speed isn't what it is meant for and it doesn't position you to go that fast very easily.
there more things at play that just weight. 10lbs isn't so much unless you're going up hills a lot
