Tengak-tengok signifies “looking around repeatedly” in Indonesian. There are many bicyclists cruising the streets and cul-de-sacs (culs-de-sac? ehh) of Jakarta, hawking various foods, wares and services; much of the goods they have are just as easily found as many other parts of the world, so I tried to snap a few shots of less-common, or at least more likely to be found in residential area mobile merchants. Also, my work schedule at the time permitted a lot of exploring around the Big Durian, thus the desire to tengak-tengok for good eats and rusty diversions (you’ll see) soon enough) wherever I randomly ended up, be it here or the hotel next to here.

Have you collected them all? Bear in mind though, this series is not at all exhaustive as most other bike vendors I saw involved food, ergo those qualify for a separate entry.
