ABSTRACT:
A vehicle includes a frame, a pedal crank which is mounted on the frame to rotate about a first axis, a drive motor, a drive belt or drive chain for transmission of force from the drive motor to a drive wheel, with the drive wheel being mounted resiliently on the frame via a rocker. The pivot axis of the rocker in relation to the frame is coaxial with respect to the drive motor and coincides with the axis of a first gearwheel which is driven by the drive motor and about which the drive belt or drive chain is deflected.
