sähköavusteisuutta

Sähköavusteisuus, often translated as electric assistance or simply e-assist, refers to the use of an electric motor to supplement the power input of a human or another prime mover. This concept is most commonly encountered in the context of bicycles, known as e-bikes or pedelecs. In this application, a small electric motor provides additional propulsion, making it easier to cycle, especially on inclines or over longer distances. The assistance is typically activated when the rider pedals, and its level can often be adjusted.

Beyond bicycles, sähköavusteisuus can be found in other forms of personal mobility devices like electric scooters and electric wheelchairs. In these cases, the electric motor is the primary source of propulsion, with human input potentially used for steering or minor adjustments. The term can also extend to industrial applications where electric motors are used to reduce the physical effort required for tasks like lifting, pulling, or rotating heavy objects, thereby improving efficiency and reducing operator fatigue. The core principle remains the same: leveraging electrical energy to lessen the burden on the primary power source. This technology aims to enhance accessibility, extend range, and improve the overall user experience by making physical exertion less demanding.
