Wonderful street-level photos of ordinary people and everyday life!
I'm always attuned to bikes in photos from other places, and I spotted several like this:
Roller lever (rod-operated brakes) and a full chaincase, typical of English Roadster bikes from the 1930s through the 1970s, and still manufactured in India and probably in China. They probably have the metric equivalent of 28-inch wheels, too. This one has a single-speed hub, though, whereas the English Roadsters typically came with Sturmey-Archer 3-speeds. The bikes weigh in at about 35 pounds but roll surprisingly easily, and the low frame angles provide stable handling and a comfortable ride even on rough streets.
