Abstract
An electric bicycle includes a front wheel, a rear wheel, an electric traction motor which drives the front and/or rear wheel, a traction battery which supplies the electric traction motor with electrical power, a controller for actuating the electric traction motor, a pushing-aid controller for controlling an adaptive pushing-aid function which is assisted by the electric traction motor depending on an interaction force between a person pushing and the electric bicycle, an inclination sensor for determining an inclination angle of the electric bicycle relative to the ground, a traction-motor torque determining device for determining a current traction-motor torque, an electric-bicycle speed sensor for determining a current electric-bicycle speed, and an electric-bicycle weight memory which stores a current electric-bicycle weight value. The interaction force is determined by the pushing-aid controller from the inclination angle, the current traction-motor torque, the current electric-bicycle speed, and the current electric-bicycle weight value.
