Wow, he is one with that bike, isn't he? Good balance skills too. Glad to see him wearing a helmet.
When I was a pup, we had ten speeds max. You had basically 3 styles of bicycle.
The old fashioned style (most comfortable imo) , the "English Racer" (10 speed), and the hot new "Sting Ray".
We just road in straight lines, on the street, and maybe popped a wheely now and then.
I'm just amazed how things, in so many areas of life, have advanced in my lifetime.
