Down the street

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

@pentaxuser You're right, that bike is clearly a modern, exotic, expensive "fixie."

To bad kids just can't be kids these days. These ones are some of the rare fortunate ones. Great shot and would be great as part of a collection.
