  You can set a bicycle pump to "suck"??? by Concept2006-11-20 12:10:51

      looks like the pump we used for the air beds, by zoxer 2006-11-20 13:46:08
nothing special or "hi tec", only cheap pvc. And no, very different from a bicycle pump. With my bicycle pump I can put 7 bar (100 psi) with 10 strokes on a 406x47 (20x1,75) tube (12bar max). With that pump you can't do more than 1 bar. For pumping you put the tube to one opening, for sucking to the other. And with the bicycle pump, even with a pump that pumps with each, not only each second, stroke you can't suck, for the tube it has only the pump opening, not that for sucking.
