Thank poVoq. lowtech is the posterchild for most of what we are discussing.

I find it interesting you can get basically different results by focusing on singular points. I can’t imagine in the future there will be a strong mining industry still churning out batteries that fit every proprietary connector. Perhaps if the e-bike industry went open source and shared designs would be the best of both worlds.

A used, commonly found steel framed bike with nonproprietary parts, local carbohydrates, downhill both ways sounds like the perfect situation.
