I will be 66 this year and have been staying in shape riding to my 87 year old moms house a few times a week. She lives on top of a hill with a great view so the hill gives me a great workout. I also use my bike for all local errands like to the farmers market, bank, supermarket etc. Here is a video of my two grandsons looking at hot air balloons from my mom's porch with her in the background.
