A drive unit () for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (), an electric motor () with a stator () and a rotor (), a stator support (), and an electronic unit (). The stator support (), the stator (), the rotor (), and the electronic unit () are designed in the form of one unit (), which can be preassembled so that the preassembled unit () is installable into the housing ().

Drive unit

A drive unit () for a manually driven vehicle, in particular a bicycle or an EPAC, includes a housing (), an electric motor () with a rotor (), a bottom bracket shaft (), a harmonic drive () coupled to the rotor (), and an output shaft (). The harmonic drive () includes an outer bushing with an inner toothing. The outer bushing () of the harmonic drive () is coupled to the housing () via a buffer ().

A transportable outboard drive for a boat has a head, a pylon, a shaft connecting the head and the pylon, an electric motor and a cable running inside the shaft. The shaft has at least two shaft sections and wherein the head, shaft and pylon can be arranged in a working configuration or in a transport configuration. In the working configuration, the head, the shaft and the pylon are rigidly connected to each other. In the working configuration and the transport configuration, the cable and shaft are differently positioned with respect to each other, whereas, in its transport configuration, the shaft sections are separated from each other.
