Part III: rear part, Vee formation 12 is provided with parallel two, and trailing wheel 11 clamps and is fixed on 12 of two Vee formations. Above Vee formation 12 front ends, connect a load-carrying Fender frame 10, load-carrying Fender frame 10 is formed by carbon fibre material compacting, and front end has the seat tube seat seat 101 that Open Side Down, and is provided with the U-shaped hole seat 102 fixing with Vee formation 12, as shown in Figure 4. The inside position of sitting tube seat seat 101 has elasticity, and its size coordinates with the diameter of sitting pipe 8 lower ends. The rack wheel 14 that 4 diameters are 60mm is established in the top of load-carrying Fender frame 10, and rack wheel 14 lays respectively at the position, rear and front end of load-carrying Fender frame 10.
Rotating shaft 13 is greater than rotating shaft 13 to the distance between foot pedal axle core hole 5 to the distance between the nearest wheel outer rim of trailing wheel 11, to ensure that folding rear whole trailing wheel is positioned at foot pedal axle core hole 5 above and the below of rear vehicle frame 7.
When folding, the first step, pulls open universal separator 9,, taking rotating shaft 13 as rotating shaft, overturns forward downwards in rear part, until trailing wheel 11 is positioned at rear vehicle frame 7 belows, as shown in Figure 7, and load-carrying Fender frame 10 turn-overs, rack wheel 14 is on the spot.
Second step, unclamps folding device for car body 6, and front part is partly turned down in car, makes front-wheel 1 basic parallel with trailing wheel 11, as shown in Figure 8.
The 3rd step, unties handlebar folder 3, and handlebar 4 is turned down downwards, transverse handle and front-wheel 1 side plane is close to, as shown in Figure 9.
The 4th step, unclamps and sits pipe clamp 91, and seat 16 is downward by inserting together with sitting pipe 8, makes to sit pipe 8 lower ends and is positioned at the interior aerial of seat tube seat seat 101.
When expansion, step is contrary with folding process, after expansion as shown in figure 11. Fastening each position folder or locking device can use.
Above-described embodiment is to explanation of the present invention, is not limitation of the invention, any structure after simple transformation of the present invention, method is all belonged to protection scope of the present invention.
