Abstract
The utility model relates to a bicycle frame, in particular to an electrical bicycle frame. The technical scheme of the utility model includes that an electrical bicycle frame is integrally made of magnesium alloy via die-casting, wherein the frame is an integral frame formed by connecting a rear hub supporting portion, a bottom bracket bearing supporting portion and a seat supporting portion according to a mode of integral die casting, and a foldable front beam of the electrical bicycle formed by integral die casting is connected with one side of the integral frame via a pin shaft. After the integrated die-cast frame is hinged with the integrated die-cast front beam via the pin shaft, the frame and the front beam present a cross shape when unfolding and a triangle shape when folding. The electrical bicycle frame has the advantages that strength reduction and defects of welding process caused by welding are avoided by utilizing the technique of integral die-casting, which has long-term benefits with one-time investment and is adaptable to mass production of electrical bicycles, further, because the upper portion of a driving chain of the electrical bicycle is disposed inside the frame, a chain guard is saved and the attractive effect is achieved simultaneously, and furthermore, the bicycle frame is simple in folding and easy in styling design.
