I kind of only have one for sure keeper, my 1963 Hercules 3 speed, I did a full resto mod build on it about 15 years ago. Its my townie, but I do take it on longer rides too, rode a century on it earlier this summer, averaged 16 MPH, and rode it 41 miles a few days ago, I was on the cranks hard and averaged 18.5 MPH. It's not my fastest bike, and certainly not the lightest, but there isn't another one like it, it is *mine*. I get just a little bit giddy every time I throw my leg over it to ride to town :-)
