It's amazing what you come across by searching for "bicycle" in Google News. I just stumbled across this story about the Africa Bike: a heavy single speed with coaster brakes that is apparently just what the doctor ordered for remote regions of the African continent. This thing is 45 lbs. and carries 100 kg of cargo (that's 220 lbs!).
It may not win any crits, or get oogled by the fixie riders downtown, but it's nice to see a bicycle that fills a strong need in communities without many options.
