Increasingly, in an editorial post meet the voluminous packages of drawings and descriptions of improvised microvesicles. Their fundamental difference from development of previous years — a successful combination in the construction standard and improvised units. The second important detail — the sharp improvement in appearance, a bold design decision.
On these pages we present to the readers micromatics, which fully include the characteristics described above.
Developing the layout of your microvesicle, I came to the conclusion that the fuel tank can be made an integral part of the power frame. This gave the opportunity to reduce the weight of the machine and give it a more dynamic shape. Application for oval frame tubes allowed to make “Grasshopper” strong enough, easy and, most importantly, small size. When folded the wheel of his dimensions fit into a box 195x750x1050 mm, which allows it to freely accommodate the trunk of the car, in the Elevator, and even under the bed.
This microvesicle frame is welded from thin-walled (with wall thickness up to 1.5 mm) steel pipe. All the elements of the frame (except the fuel tank) are connected by welding, not immediately, but gradually individual nodes with intermediate straightening, because the leash was significant. Parts fuel tank was connected by gas welding.

And now more about the bike and the manner of its Assembly.
The gas tank is not only a fuel bottle, it and the power element of the frame. It is based on steel pipe Ø 102X1,5 mm. After marking and trimming welded thereto a pipe with a diameter of 20 and a length of 108 mm. and Then at the end of the device superimposed steel plates, outlines in his contours, cut and welded.
Next, adjusted the head frame is welded, n in case cut the holes for the tank filler and drain fitting of the fuel, which are then soldered into the tank.
Made telescopic front fork, spring shock absorbers. The bridge plug is machined on a lathe, then milled and reams and rastaquouere hole. The axis of the bridge plugs, covers telescopic shock absorbers and the tips of the feathers pressed into the bridge and opasayutsya brass. When assembling the pens of the fork fills with grease.

Pendulum fork rear suspension also homemade. To the frame it is secured by two M8 bolts in the place where the axis of the drive sprocket. The bolts must be strictly aligned to each other.
Wheel designed for the standard samokatnaya tires. Rims homemade, chiseled. The hub and spokes of the front Bicycle wheel and rim rear wheel connects with a homemade hub eighteen spokes of the wheel of a moped “Lviv”.
Brake drum and pads made of aluminum alloy D16T. Each pad is machined on a lathe with the subsequent drilling and milling. Made thus pads aluminum wire riveted friction lining.

Exhaust pipe is picked from the regular knee-engine sh-58, bushing and muffler. The knee is being finalized — it should be bent as shown in the figure.
Motorcycle seat — sheet duralumin, polyurethane foam, dense fabric and faux leather in black.
Tool kit hidden under the seat of microvesicle. It is made of sheet aluminum with a thickness of 1 mm.
The Color “Grasshopper”. After welding the frame thoroughly cleaned, removed rust, slag and spatter. Then it should be primed and then painted in several layers. The color depends on your ability and taste. For example, I used the black nitroenamel and to the tank through a stencil depicted nitro white silhouette of a grasshopper. Exhaust pipe, feathers, forks, hub rear wheel, bridge wheel and rim chrome.
