Question

Why does pedaling up hill feels harder than walking up the same hill?

In: Physics

Answer 1

When you’re walking up a hill you are carrying only yourself. When you’re bicycling up a hill you are carrying both yourself and the bike.

The additional weight of the bike coupled with the fact that gravity is constantly trying to pull the bike down the hill means more effort is required to get up the hill.
