Why don't you call her and apologize for the asshat move, ask to try the bike riding thing again.
At least you can make amends, good excuse for another date.
That takes a little courage, and women tend to like a man that's a man.
As it stands, for you it's one day of 365.
For her, you are just a tool: full stop.
Then again, maybe she's just not that into you... please tell me you didn't wear lycra shorts...
