Thanks for all the great replies, please keep em coming. So far things are great with us, I always try to reward for her for our rides.
While on the trainer inside, she gets a couple oreos and she gets to watch extra TV while we ride, she is usually limited to about 45 minutes. She picks the movie and we ride while we watch. When riding outside, we try to always ride somewhere like the party supply store. I'm guessing that one day, these rewards won't be good enough anymore.
