http://www.thinkbiologic.com. The BioLogic PostPump is a full capacity bicycle pump build into the seatpost. Pump up your tire easily and conveniently in less than half the strokes of the best mini-pumps. Works just like a regular floor pump.
I have a Dahon Matrix '07 with a similar biologic seatpost pump. It's really great having a pump with you all the time without even thinking about it, and it actually works better than those little hand pumps. You do feel a little funny pumping up your tires using your seat. :-)
thanks, there was no directions on how this thing works, great, now I can do it.
