The bicycle does give you a lot of mechanical advantage over walking. But also this depends on road surface, condition of the bicycle and also incline. It’s hard to specifically calculate, but for most of the built up world the bicycle would clear easily. Unless you’re actively searching out loose gravel inclines to walk / bike up.

Let me give you an example, most people hate riding uphill for obvious reasons but the speeds they pull doing this would be a fast jog or a run if they were on foot
