💡 Why do some bikes handle hills better?

You may notice that Mid-Drive motors often finish this challenge with significantly more battery remaining than Hub Motors, even with similar battery sizes. This is because Mid-Drives leverage the bike's existing gears, allowing the motor to stay in its "efficiency sweet spot" on steep climbs. Conversely, Hub Motors must work much harder at low speeds, often losing up to 25% more energy to heat when under heavy load on a hill.
