I'm going to combine benefits #6 and #7 because they are so closely related.
I may be forever known as the Biking Mom now. The kids and I bike just about anywhere we go (within reason, of course), particularly in the summer when we have relaxed schedules and nice weather. As a result, Benny has made some pretty significant round-trip treks. I think his longest ride to date was nearly 8 miles this summer - to go swimming no less.
Biking has become so predominant in our routine that a ride in the car is now a "treat." The kids have been trained to go to the back door when we're preparing to leave because that's where we retrieve the bikes. They typically don't complain about it any more either.
I've gotten better at being a biking mom. I know how to bundle Benny and Lila up appropriately and I have a 30-degree rule. If it's below 30, we don't ride. That means that we can't ride to school in the winter time, but we can ride home (thanks to the Burley trailer that has enough room for Benny's scooter). When it's hot outside, I'm smarter about bringing water and snacks and taking enough breaks. It's been a learning process, but we've nearly mastered it.
