The award-winning BioLogic™ Zorin PostPump is an ingenious combination of a seat post and powerful floor pump. The pump mechanism is hidden inside the seat post so the pump is always at hand, hidden from the elements and thieves. The high capacity BioLogic™ pump can inflate a tire in as few as a dozen strokes and can easily reach 110 psi. Ergonomically, the PostPump is just like a floor pump: you stand while you pump and use the saddle as a handle. So say good-bye to crappy mini pumps, kneeling in the dirt, and arm cramps. Dahon patented technology.
