Shown with reference to Fig. 1 and Fig. 2, be the preferred embodiment that the utility model provides.

The auxiliary wheel of the folding electric bicycle provided in this embodiment is used to be arranged on the rear wheel 14 of the folding electric bicycle, and is placed stably when the folding electric bicycle is in a folded or unfolded state, so as to prevent it from tilting sideways.

The auxiliary wheel of the foldable electric bicycle provided in this embodiment includes a support rod 12 and an auxiliary wheel 13. One end of the support rod 12 is movably connected with the auxiliary wheel 13, and the auxiliary wheel 13 rotates with the center of the wheel as the axis. The support rods 12 are respectively arranged on On both sides of the rear bracket 11, the lower end of the rear bracket 11 is connected with the rear wheel 14, and the upper end of the rear bracket 11 is hinged with the front bracket 15, and the front bracket 15 is folded with the rear bracket 11 by swinging so as to realize the folding of the electric vehicle. The other end of the support rod 12 is connected to the rear bracket 11, and swings around the center of the rear wheel 14 as an axis.

In this way, by setting the support bar 12 with the auxiliary wheels 13 on both sides of the rear bracket 11, when in the folded state, the rear wheels 14 and the auxiliary wheels 13 on both sides are jointly supported, and the three legs stand upright, thus the folding state in the folded state is supported. The electric vehicle is stably supported, and the rear wheel 14 and the auxiliary wheels 13 on both sides are rotating wheels, which can push or drag the folding electric vehicle in the stacked state, making it more convenient and easy to carry the folding electric vehicle; In addition, when the folding electric vehicle is unfolded to the state of use, the auxiliary wheel 13 is swung around the wheel center of the rear wheel 14, so that the front wheel 16, the rear wheel 14 and the auxiliary wheel 13 of the folding electric vehicle are on the same plane. Stable placement of the foldable electric vehicle in the unfolded state without tilting to the side, and by pushing or dragging, the movement of the foldable electric vehicle in the use state is realized, not limited to the dynamic and smooth movement in the riding state .

In this embodiment, the rear bracket 11 has a first rear bracket 111 and a second rear bracket 112, and the support rod 12 includes a first support rod 121 and a second support rod 122. The first support rod 121 and the first rear bracket 111 Hinged, the second support rod 122 is hinged with the second rear bracket 112, and the other end of the first support rod 121 is movably connected with the first auxiliary wheel 131, and the other end of the second support rod 122 is movably connected with the second auxiliary wheel 132, In this way, the rear bracket 11 has two pieces, which are respectively hinged with the front bracket 15. When the foldable electric vehicle is folded, the front bracket 15 can be embedded in the rear bracket 11, so that the stacking is more compact, and the rear bracket 11 both sides The auxiliary wheels 13 can be swung separately, that is, according to the terrain, the folding electric vehicle can be swung more firmly.
