You want to be able to look at your phone's screen while you're riding? It'll have to be at least 16" away from your eyes so you can focus on it. Google glasses project a virtual image at infinity so it's in the same focal plane as the scenery. You don't need to change focus to see it. And it's semi transparent so you can see through it. That's quite a bit different than hanging a phone on a stick in front of your face.
