Portable foldable electric bicycle

Abstract

The invention discloses a portable foldable electric bicycle. The portable foldable electric bicycle comprises a frame body, wherein the frame body comprises main beams, support beams, cross beams and a lockable frame folding mechanism; the front ends of the main beams are rotatably connected with a front fork vertical tube through the frame folding mechanism; the rear ends of the main beams are rotatably connected with a rear wheel; the support beams are pivoted with the main beams in an intersected manner; the lower end of the support beams are connected with pedals; the front ends of the cross beams are connected with the main beams in a vertically rotary manner; the front ends of the cross beams are also connected with the front fork vertical tube in a front and rear rotary manner through the frame folding mechanism; the rear ends of the cross beams are provided with sliding grooves with lock-up grooves; the upper ends of the support beams are connected with the cross beams in a front and rear sliding manner through connection pins which are inserted in the sliding grooves; and a saddle is arranged on the cross beams, and is located between connection points of the cross beams and the main beams and the connection points of the cross beams and the support beams. According to the foldable electric bicycle, requirements on strength of steel is lowered; the manufacture cost is lowered; and the foldable electric bicycle has the advantages of being light in weight and convenient for carrying.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a portable foldable electric vehicle and belongs to the technical field of electric vehicles. Background technique [0002] As a kind of green and environment-friendly means of transportation, bicycles and electric bicycles have the advantages of low price, light travel and easy docking relative to motor vehicles, and have become common means of transportation for people at present.
