The father-son duo at Wolf Creative Customs has been crafting some fine motorized bicycles for quite a while now, all of them placing function over form. Take a look at this sweet board tracker inspired custom, which we think is a perfect blend between bicycles and engines. The air-cooled, single cylinder 200cc engine is fed by a 22mm Mikuni carburettor, while the straight pipe exhaust lets the engine breathe to its full potential. The frame is a modified bicycle unit designed by Richard Nelson Helmutt, accompanied by front and rear disc brakes, as well as a reduction drive system based on the same design as the old board track racers.
