OK, get a quarter. Assign a bike to heads or tails. Toss but don't look yet.
Now, here's the trick. Take a peek. if a particular bike come up, and you're first reaction is a sense of disappointment, even fleeting, then you know you really want to take the other.
OTOH - if the first reaction is great!, then all is right.
But remember hat only the immediate fleeting reaction count, so don't think about again unless you decide that you want to change your mind.
