Doesn’t that statistic assume a 60W incandescent?

yea, but the best LED bulbs are something like 4x more efficient.

So biking for an hour runs a LED lightbulb for 10 minutes maybe? I don't remember the exact figures but it's ridiculously impractical

a fully distributed generation system comprising manual labor, geothermal, hydro, and some form of energy storage

it's also impossible to make a system that takes advantage of the type of post-collapse labor you'd be doing. People won't be riding exercise bikes when you're trying to survive off potatoes and milk
