I was in a hurry the morning my bicycle chain broke. One long hill, smooth sailing to Byzantium, and by God I was going to make it to Betty Pilager’s house before she slipped away forever. I wanted a goodbye kiss. Instead, I got a bruised crotch and what was darn close to if not an actual concussion. 
  Betty Pilager slipped away forever.
  “Mike?” a voice hovered somewhere.
  I opened my eyes and saw two directions at once. Somewhere in the middle was my best friend, Norman Atwater.
  “Hmm…” I said, dreamily. I don’t recall what I was thinking about at the time but it sure wasn’t Norman Atwater.
  “Hey Mike! You okay?”
  “Uh-uh.”
 
Sorry if I came off as rude btw...

After all this is only the first 13 lines.
Here are my suggestions:
The first lines are awkward. I would start with "I wanted a goodbye kiss. Instead, I got a bruised..." Then go on to say I would have made it if my bike chain ect....
"I don't recall what I was thinking about at the time but ti sure wasn't Norman Atwater."
My thing is you just recalled to us what you were thinking about: Betty and her kiss.
I agree with RoxyL your voice is great. I would read on to answer the whys mentioned by starsin, but make very sure you answer all those before the story is over.
 
 Again, for reasons of your voice. You've got a bit of a whiplash humor going on here, quick and precise and occasionally abrupt.

I really like these lines:

*except* for the "what was darn close to if not an actual . . ." that slows the snappiness *way* down. And especially since you have him seeing two directions in the next couple lines, I'd just ditch the hedging and say "I got a bruised crotch and a concussion."
My other nit is that, in jumping from "the morning my bicycle chain broke" immediately to him riding said bike, and then the results of the chain breaking . . . it jumps back and forth too quickly over too short a time period to really be useful in the "this is what happened. Now let me tell you about it . . ." sort of way. I'd ditch the "flashback" and just tell it chronologically. Just start at "One long hill . . ." and go from there.   
Also, I'm left rather curious about "Byzantium" . . . is that some kind of allusion to his dream girl's kiss? I'm assuming he's not *actually* biking down to the ancient Greek city . . . I'd have to look it up to see if I'm missing something.

Well, technically, he was thinking about that before the wreck, not afterwards. Maybe I should make that clearer.
Tryndakai - "Sailing To Byzantium" is used very loosely here, but if you google it you'll get the gist. I stole it from a Yeats poem, but so have a lot of other people.
