No they don't. With geared bikes you have to sacrifice speed/distance for the ease-of-effort. You don't get energy for free. Any no-motor geared-bike is 100% human powered --> no matter what the gears.
Motorized-eBikes add energy that comes from the Electrical Power Grid. They ARE NOT 100% human powered, but are boosted 300% by electricity.
