I enjoy being outside in the fresh air be it in the early morning or on the way home.
I love not being stuck in traffic waiting for endless stoplight cycles and idiots trying to get in front of me or pull across 6 lanes of traffic.
It's nice not paying $50 every week or so for gas.
Saves wear & tear on the car so lower maintenance costs.
You meet people of like mindedness - who are [usually] pretty cool.
Enjoyable exercise.
