Abstract
The invention discloses a folding bicycle with a folded frame and fully covered wheels. The bicycle comprises a frame, a saddle, a handle, a handle vertical tube, a front fork, a front wheel, a rear wheel and a power device which drives the wheels to rotate. The frame comprises a front frame, a frame beam, an upper frame and a rear frame. The area enclosed by the front frame, the frame beam and the upper frame is an erected triangular area. The frame forms into a quadrilateral structure in the folding process and forms into a frame covering the front wheel and the rear wheel after being folded. The whole folding bicycle forms into a frame after being folded for two times. The front wheel and the rear wheel are side by side and lean against each other and are covered in a plane enclosed bythe frame folded by the bicycle frame. The front wheel is in an arc-shaped bended beam of the lower frame, and the rear wheel is in an arc-shaped bended beam of the upper frame. The bicycle is vertically folded, so that the frame can be integrally folded. The folded frame can cover the wheels fully, so that the bicycle folded is convenient to fold and operate, small in volume and sanitary, and convenient to carry.
