What's a torque sensor? Why does it matter?

A torque sensor measures how hard you're pedalling and delivers power in proportion to your effort. Pedal harder, get more assist – pedal lighter, get less. It makes the ride feel natural, smooth, and intuitive, like you've suddenly got superhuman legs. Models with torque sensors are significantly more responsive than those with basic cadence sensors (which just detect pedal rotation).

What does "Wh" mean on a battery? (e.g. 499Wh, 720Wh)

Wh (Watt-hours) is the total energy capacity of the battery – like the size of a fuel tank. A higher Wh number means more range. For example, a 720Wh battery will generally take you further than a 499Wh battery, assuming the same bike and riding conditions.
