I've posted about the buffallo before, which is like a relief aid bicycle for poor nations, but here's Seth of Berm Peaks reviewing it, with details I didn't know hitherto. I posted about it before and it is fascinating to me so here you go.

To give context on seth here, he's quite obviously not a comrade, but he's also not a shit. Ad sponsors, yes, but I'd argue he always does point out you don't need all the expensive shit, it's just nice.

I think this might come as close to the nigh-perfect general purpose post-apocalypse vehicle as you can get. Seems thought-through. But read the other threads for possible critcisms on it.
