I'm just getting started commuting to work. It's not that far, maybe five miles each way, but I live in a Chinese city and it offers its own challenges. I'm an American, but when I was younger (19) I lived in Germany and rode bikes 100% for my transportation. I loved it. I started riding dirt bikes when I was a kid and in my 40's started riding big street bikes. I just love being out there in the wind. Now, I'm back to enjoying cycling every day. Oh, and I lost 90 lbs. this past year and this is a good exercise supplement to keep me headed in the right direction. This is what keeps me motivated.
