Having used a Biologic Zorin Postpump with our Dahons during our Mobile Social Worldwide, I wish they’d license that technology and I could have a seat pump on my rain and touring bikes.
There’s no consumer truth-in-pumping requirement and minipumps manufactures will promise you pumping power. They’re lying. A pump no bigger than a lipstick case will NOT inflate your road tire. Minipumps do not pump well. In the Northwest, most cyclists I ride with have given up on minipumps and carry Co2.
