Abstract

The invention relates to a single-beam travel companion bicycle which comprises handlebars, a saddle, a saddle tube, a frame stand tube, a storage rack, double brackets with truckles, the truckles, a frame rear fork, a rear wheel, a centre shaft, a crank chain wheel and a front wheel; a frame main tube is divided into a frame main tube front section and a frame main tube rear section which are separately arranged in front of the centre shaft and the crank chain wheel, a folding device is arranged at the separation part of the two sections, and the folding direction of the folding device is downward; the distance from the centre shaft to the frame stand tube is greater than the diameters of the wheels; and the folding device consists of a circular handwheel, a triangular compression strip,a rear part with a sector-shaped side face, a nut, a screw rod, a front part with a bar-shaped side face, a rotating shaft, a positioning inclined surface and a positioning notch. The single-beam travel companion bicycle disclosed by the invention has the advantages that a folding method is simper, rapider and easier; and a folded bicycle is flat in volume and small in occupying area, is more suitable for entering subways and buses, can be pulled to move and used for loading luggage and is more convenient for use and carrying.

Description

technical field [0001] The invention relates to a bicycle, in particular to a single-girder travel companion bicycle. Background technique [0002] In the prior art, folding bicycles are generally folded around the middle of the vehicle frame, and the two wheels are basically overlapped and parallel after folding. The bicycle folded in this way is actually inconvenient to carry. The reason is that because the wheels are generally large, the volume is still large after folding, so it can be put into the trunk of a car, but it is really not suitable for hand-carrying or shoulder-carrying. If pulling or promoting, then this kind of folding bicycle is because of being subjected to the restriction of folding mode, and its pulling or pushing performance is relatively poor. Contents of the invention [0003] The object of the present invention is to provide a single-girder travel companion bicycle, which solves the problem of inconvenient pulling and carrying existing in folding...
