The invention relates to a portable and folding electric bicycle. The portable and folding electric bicycle solves the problem that an existing electric bicycle is not convenient to carry due to the large size. The portable and folding electric bicycle comprises a handlebar, a front wheel, a rear wheel, a saddle, a transmission mechanism, a bicycle frame, a front fork, a rear fork, a front clamping pin mechanism, a rear clamping pin mechanism, a first plug pin mechanism and a second plug pin mechanism. The bicycle frame is composed of a vertical pipe, a front fork vertical pipe, a front bicycle frame body, a rear bicycle frame body, a saddle vertical pipe and a damping limiter. The saddle is inserted into the upper end of the saddle vertical pipe through the saddle pipe. A saddle pipe clamp controls a saddle pipe to move up and down inside the saddle vertical pipe. The lower end of the saddle vertical pipe is pivoted to the rear middle end of the rear bicycle frame body. The upper end of the damping limiter is pivoted to the middle end of the saddle vertical pipe. The lower end of the damping limiter is pivoted to the rear end of the rear bicycle frame body. The front end of the rear bicycle frame body and the rear end of the front bicycle frame body are pivoted through a crankshaft. A vertical pipe side plate and the front end of the front bicycle frame body are pivoted through a front bicycle frame rotating shaft. Handlebar transverse pipes are inserted into the two ends of the handlebar respectively. The lower end of the handlebar is inserted into the front fork vertical pipe. The front wheel is installed on the front fork. The portable and folding electric bicycle has the advantages that the size is obviously decreased after the portable and folding electric bicycle is folded, the weight is low, manufacturing is easy, carrying is convenient, environmental protection is achieved, and the market prospect is quite wide.
