People can generally only output their max power for short durations. The output level they can sustain is generally much lower. I bet you could try to model higher limits for short distances, but what those should be could vary greatly depending on personal fitness.

I think that too favors walking the bike up the incline. Anyone able-bodied should be able to do it, some faster than others, but biking up an SF incline is more hit or miss, especially when considering different bikes.

My reasoning for the bike-hike being faster is that legs are designed for it. Legs are only inefficient on flatter ground because you have no equivalent of high gear (like extendible legs), so all that torque is going to waste.

Uhh, excuse me? Legs are inefficient on flatter ground because they don't have wheels.

Legs have to start, go up, go down, stop.

Wheels go brrrrr.

I believe the "wheels on the bus go round and round" :-)

BRouter models this as inertia, I believe.

But hike a bike is no fun, especially if trying not to sweat
