Generally speaking, an electric bike is a regular push-bike with a battery-and motor-powered “assist” that comes via pedalling and, in some cases, a throttle. The main components of the electric bikes are electric motor, battery, drivetrain, controller, pedalling sensors and display. The battery powers the motor which in turn releases kinetic energy to the drivetrain. The drivetrain then applies torque and manual power to move the wheels without exhausting the rider.
