Good day to all! For a long time I wanted to post my topic on this forum.
First, by the name of this monster. What is a dhampir? We open google and find something like this: "Dhampir is half human, half vampire." Dampires is generally portrayed as one with all or most powers of a vampire, with few to no disadvantages."
If it is easier, then the concept of this bike is simple. Ideally, it should take the best from both kinds of transport and, if possible, not have their disadvantages. From bicycle - size, weight and the ability to ride pedals. From a light motorcycle - the dynamics of acceleration and cruising speed. All this - with weight and dimensions, under which it can be stored in the apartment. Of course, because is a single-speed engine, the ideal "balance" between "bicycling" and "motorcycling" is impossible. With a big rear sprocket we get a lot of traction, but a small speed. With the small rear sprocket - a high speed, but much less acceleration dynamics.
And therefore, in more detail on the engine. It is a two-stroke water cooling engine from ktm sx 50 dirt bike. A resonator tuve was welded now. And rotor of the water pump is made on the CNC. For the engine were purchased two radiators from KTM SX 65 and 19mm Dellorto PHBG carburetor.
The frame of this bike was welded from a thick-walled steel profile. Main part (top, down and seat tubes) - from 50x50x3mm square tube, and for chain and seat stays - 40x20x2mm tube. Weight of a complete frame is 16kg. Weight of a complete bike is 56kg.
The head tube, the bottom bracket shell and top of the seat tube is made from steel on a lathe. Saddle - lepper primus.

weighs like 8 kilograms, about the same as a whole road bike. I used to have one, and I miss it.
