Chicago-based nonprofit World Bicycle Relief (WBR) doesn’t distribute just any type of bicycle ??? it distributes bicycles meant to navigate the unimproved roads and rough terrain of developing nations, empowering populations to access healthcare, education and economic opportunities that would???
For some background about World Bicycle Relief and the original “Buffalo Bike”, see this video by Berm Peak on Nebula (also YouTube).
As for the 2-chainz design, I think it’s fairly brilliant, as a way to avoid a delicate derailleur, which MTBers will know is vulnerable on terrain due to being low-slung. This sort of thinking also highlights how engineering and design make tradeoffs, since the weight penalty of an extra chain is not important when the ultimate objective is a rugged, durable bicycle.
Your “2-Chainz” link goes to the article on the actor, not the bicycle design.
That’s the joke
