E-bike Powertrain

The powertrain in an electric bicycle refers to the group of components that generate power and deliver it to the road surface. This includes the electric motor driven by the battery pack, human power, and transmission part. As you can see from the picture, when human being starts pedaling the electric bicycle the assistant motor also works at the same time. By calculating the input power which contains human pedaling power and the power delivered by the battery and the output power on the rear wheel, we can get the efficiency of the powertain.
