When you guys say "light bmx bike" what are you talking about in lbs? I've heard a lot about 30+ lbs bmx bikes and it seems crazy to me that a small bike with no gears, suspention, etc. could weigh that much.
I too am thinking of getting a bmx bike so i don't wreck my nice xc mountain bike dirt jumping
but i don't know if I can give up the light weight (my bike is 25lbs, and I intend to drop a few lbs in upgrades over the next year or two).
