I wasn't quite 10 yet in the 50's, but that's when I first graduated from a tricycle to my first 2 wheeler, and I've never looked back. In those days, kids, boys especially, pretty much lived on their bikes. For me, it became a lifelong passion, but unlike many of today's speed, weight and race obsessed people, it was tied in with a love for the sights, smells and sounds of nature, with freedom and with a kind of meditative contemplation of life. Most of the other kids I rode my bike with probably long ago became suburban car people. Why most do, and a very few of us stick with cycling as a passion into advancing age is something I don't know. I guess that among other things, it may make some people more interested in remaining as fit as possible throughout life, and because a bicycle, even a racing bicycle, is a relatively simple mechanism, it gives us an appreciation of simplicity in all things.
I enjoyed looking at those pics. Thanks for posting the link.
