drag agreed!!!!

Ok, you're looking at the bike in completely the wrong way. The way the bike works is through the size of the gears, not the weight. A smaller gear at the pedals in relation to a bigger gear in the rear will give you more torque, or help you accelerate faster. A bigger gear at the pedals in relation to a smaller gear at the wheel will result in a higher top speed with slower pedaling. It's just like a car. You start in first to get yourself up to speed and then end up in 6th to keep a high speed with low engine speeds.

You have the right idea here I think. Think of it as the difference between crank horse power and wheel horse power. Crank horsepower is how much the engine itself can make, wheel horsepower is how much the car can actually use after turning the flywheel, transmission, and wheels. When you lighten up the flywheel it doesn't take as much energy to turn and therefore wheel horsepower goes up. Crank horsepower will still be exactly the same, but the amount you actually get to use at the wheels is higher.
