摘要： A foldable bicycle contains: a front frame, a rear frame, and a folding device. The front frame includes a front fork connected on a front wheel, and the rear frame includes a rear fork connected on a rear wheel and includes a seatpost coupled with a connection post and a saddle. The folding device is rotatably connected between the front frame and the second frame. The front fork has a sole column, the front wheel is inserted through a hub by using a hollow hub shaft to connect with the sole column, and the hollow hub shaft has a first connection element defined in a central portion thereof The rear wheel has a second connection element extending outward from a central portion thereof so as to fit with the first connection element after folding the front wheel and the second wheel.
