Abstract
A hybrid drive mechanism for a wheel-driven vehicle. The drive mechanism has an electromotor with a rotor and a stator as a first drive source, with a first speed and a first torque, and a pedal drive as a second drive source, with a second speed and a second torque. The stator of the electromotor is positioned on an axle or shaft of the drive train between the pedal crank and the drive wheel, preferably on a wheel axis, in such a way that it can rotate. The stator can be coupled mechanically with the second drive source so that the stator is driven by the second drive source, and the rotor of the electromotor has a speed which corresponds to the sum of the first speed of the first drive and the second speed of the second drive.
