Bicycle frame with storage compartment, where the frame has an approximately vertical oblique head tube at the front, an approximately vertical oblique rear frame tube at the rear that accommodates a seatpost, at the lower end of which it has a bore to accommodate the axle of a chain wheel or a belt drive wheel, and the rear frame tube - near the aforementioned bore - attaches to a lower frame tube that runs to the head tube obliquely and upwardly, and the parts of the frame tubes altogether surround and define a central hollow space in which the storage compartment can be placed. The lower frame tube has a bottom part (17) that runs towards the front in an approximately horizontal path to certain dimensions, and a curved frame part runs to the headtube (4) from the front end of the said bottom part section (17), and the storage compartment, made of reinforced carbon fibre or another composite sheet, is a unit encompassing a closed space that can only be opened and accessed from the top, and the said storage compartment has two approximately vertical side walls (2) and edges that are approximately perpendicular to the said side walls, and the edges attach in a form-fitting way following those parts of the frame that define the central space and partly include these parts. In case of frames made with carbon fibre technology the storage compartment can be manufactured together with the frame in the same technological step. |
