Nope - thats not exactly how it works.

Lets think of this in terms of a plumbing system. The motor generates power, think of it as a water supply.

Now, the goal here is to get the power output to the wheels - lets think of this as the faucet.

The flywheel would be analogous to a storage tank - if you turn on the water, it will first fill up the storage tank, and then after the tank is filled, it will come out of the faucet. Changing the rotational inertia of the flywheel(tank of water) doesn't make a difference in how much power goes to the wheels - all it does is store energy.

If you make the flywheel smaller - then it takes less time for the wheel to reach full speed - but it will make no difference in total power.

This explanation might be a little confusing, but I hope this is helpful.
