Flying Bike?

Wings are great, they create lift.  Spoilers on cars are like upside down wings that keep the rear end of the car on the road at high speeds.  Well what if you could design a bike more like a wing and create lift while you ride it.  If you create lift it would potentially lighten the load being hauled and allow the rider to pedal harder longer.  Imagine riding a bike and having the same power you have in your muscles now but weighing 50 lbs lighter because of lift.
