In that respect, do you suppose that conversion or upgrading a more "city" e-bike (that we already own, btw) would be a reasonable option? In theory, swapping bars, fork, and tires would be sufficient to at least be usable, but I question how stable that will be on trails with its more city-hybrid geometry. Given that the trail-riding isn't going to be anything more severe than you'd put a stock Walmart bike through, it might still be okay?
