Bicycle combination i.e. tandem bicycle, for transportation of persons and/or load, has crossbars establishing synchronously controllable connection between front wheels by catches and hinge joints

摘要

The combination has front and rear pipe frames (1, 2), front and rear wheel forks (4, 9) and front and rear wheels (7, 8) detachably connected to pairs of bicycles e.g. bicycles with pedal and hand drives by connection crossbars (16), respectively. The crossbars are mounted at the frames by connectors (17) such that a rigid connection is produced between the bicycles. The crossbars are connected with axles of the front wheels in a form-fit manner such that the crossbars establish a synchronously controllable connection between the front wheels by catches (18) and hinge joints (20).
