Nah. No offense, but give me a Surly Trucker over any e-bike. If I was not so messed up with my back, I’d still be good for 200 miles plus in one day on a couple of Snickers bars. Even in my rough shape, I can manage 30 miles daily as is and ~50 with consequences after.

Even without roads, I’m nearly as fast on a carbon 29’er hardtail like a Cannondale Flash and if I was in shape, I would want to cut my own trails anyways.

I’d probably look for a way to move to a makeshift belt drive and single speed. I could probably rig up rubber belts from cars and stuff for far longer than I’ll be able to source chains. I’d eventually be able to do a leather belt drive to stay running for awhile. The hard part will be what to do about wheels in the long term. Wooden rims were standard long before aluminum. I bet I could still salvage enough heavy canvas, glue, and scrap rubber to make my own tubulars. Yeah, I think I could be riding for many decades.

How are you at reverse engineering circuits and rewinding motors? I’ve wound my own transformers before, but a stator is a whole different beast, especially with brushless. That ~30 mile range, battery lifespan, and monstrous dead weight without power would drive me mad.
