Check out this homemade bike bell system I came across in Madagascar.The owner of the bike — perhaps the inventor — was more than happy to demonstrate.I was visiting the Cold Water Geysers of Analavory. I was not commuting per-se; I was being a tourist.The geysers are not a natural phenomenon, but instead are related to aragonite mines in the area — which somehow makes me feel slightly better about this photo:
So… Now that you can picture the geysers, back to those bike bells.The bike belonged to a guy who worked the parking lot, selling popsicles and sliced papaya to tourists. If I could speak more than 12 words of Malagasy, I might have asked him more about the bells. But all I could say was misaotra (thank you) after the demo.The bells are controlled by a stem-mounted friction shift lever.
A rubber wheel, which appears to have been made from a car tire, contacts the sidewall of the bike tire when the cable is tensioned.
Ingenious.This last photo, also taken near the geysers, gives a glimpse into how a mechanical aptitude for bikes is instilled into the Malagasy at a young age.
