Thanks everyone. I'll go back and read the manual again, and see if I can work it out. I'm also going to go back to the store and make them make me understand it.

ultraman6970: You did come off as rude. Pressing either gear doesn't seem to actually do anything. There's no click, resistance, noise, OR apparent effect on the peddling. I'm not actually even sure that I am changing gears. I fail to see how that makes me SLOW.
