One of my street photography walks, a few years ago. This whole scene reminded me of my own childhood - no smartphones, kids playing outside and free to just roam. A great life.
A bike with one gear only i.e. no derailleur mechanism. That does suggest yesteryear. I cannot tell from this side of the bike but it might be fixed wheel which in 50s and early 60s was the gear of choice for my teenage mates and me. Reminds me of my teenage years. That era is well captured here
