+1 for doing something "else" for a while. During the winter, when my bike is parked in the basement, I start spending more time with my ukulele, and find that I really enjoy THAT again after a whole biking season away from it. Then, as spring approaches, I always find myself strumming and staring out the window, daydreaming about rides again.

I've had months of disinterest in my bike, but never more than that. You'll get it back.
