The device has a first traction drive (Z1) coupling a combustion engine (1) with a wheel drive module (M). A second traction drive (Z2) couples an electromotor (2) with the wheel drive module. Step-up gears (3, 4) i.e. spur gears, are respectively provided between the first traction drive and the combustion engine and between the second traction drive and the electromotor for reducing rotational speed at a power input of the respective traction drives against the rotational speed of a drive shaft of the combustion engine and/or the electromotor. Die Erfindung bezieht sich auf eine Hybridantriebseinrichtung für ein Leichtkraftrad mit einer Brennkraftmaschine, einem Elektromotor, einem Radantriebsmodul, einem ersten Zugmitteltrieb zur Koppelung der Brennkraftmaschine mit dem Radantriebsmodul und einem zweiten Zugmitteltrieb zur Koppelung des Elektromotors mit dem Radantriebsmodul. Erfindungsgemäß ist zwischen dem ersten Zugmitteltrieb und der Brennkraftmaschine, sowie zwischen dem zweiten Zugmitteltrieb und dem Elektromotor jeweils eine Übersetzungsgetriebestufe vorgesehen, welche die Drehzahl am Leistungseingang des jeweiligen Zugmitteltriebs gegenüber der Drehzahl einer Abtriebswelle der Brennkraftmaschine bzw. des Elektromotors reduziert.
