Abstract

A frame assembly is provided for a two-wheeled vehicle, in particular for a bicycle, including: a main frame, which has a head tube for connecting to a front wheel mount and a saddle connection for connecting to a saddle; and a drive-train swing arm pivotably connected to the main frame. The drive-train swing arm includes a wheel suspension for a rear wheel to be driven and a pedal-crank drive having a pedal crank for driving the rear wheel by muscle force of a rider. The pedal-crank drive is associated with the drive-train swing arm. The drive-train swing arm is pivotably connected to the main frame by a multijoint assembly.
