The invention provides a foldable electric bicycle. The foldable electric bicycle comprises a frame, a front sway, a front wheel, a rear wheel, a pedal, a motor and a transmission device. The front sway, the front wheel, the rear wheel, the pedal, the motor and the transmission device are all arranged on the frame. The frame comprises a steering rod, a beam and a connecting rod. When the beam is lifted, the steering rod, the beam and the connecting rod form a line-shaped structure. In the front sway folding process, it is only needed to press pressing caps, and then two handlebars fall to be folded within one second. The transmission device is a wedge-shaped self-locking transmission device or pressure transmission device, traditional chain or belt transmission is replaced with static friction force transmission between a driving shaft and a driven disc, then a high transmission ratio can be achieved under the same boundary dimension, and in cooperation with a high-speed motor, the size and weight of a transmission structure can be reduced to the maximum degree. Folding and unfolding of the front sway, a body and the pedal are convenient and fast, the size is greatly reduced after folding, and then the foldable electric bicycle is convenient to carry.
