Abstract
A speed control apparatus for a bicycle includes a power-assisted unit, a control unit, and at least one of a gravity sensor (G-sensor) and an electromotive force generating unit. The power-assisted unit provides extra power to the bicycle. The G-sensor senses a slope of a road. The electromotive force generating unit produces electromotive force in response to riding of the bicycle. The control unit activates or deactivates the power-assisted unit according to the electromotive force or the slope of the road or both.
