A great read+great magazine.

TL;DR: Old bikes last way longer than new bikes. From a production standpoint, steel bikes have a smaller carbon footprint than aluminum or carbon frame bikes. Conventional bikes use fewer consumables over their usable life than electric bikes. Among electric bikes, cargo bikes use the most resources to run and maintain.

It was the specialized parts that you printed, and everything else was standard parts from the hardware store. I thought that was super cool. No clue what ever happened to that project.
