Even 3-4 lbs. make s bike "feel" sportier and accelerate faster/easier.
160lb rider on 20lb bike is 180lb of mass, 180 and 40 is 220lb mass. I guess like anything else its power to weight ratio that matters and the bike generates no power so its better to have 20lbs of weight generating no power than 40lbs of weight generating no power. So that kinda makes sense now.
