Review on Efficient Schwinn Bike Pumps: Foot and 🚲 Hand Operated, with Presta and Schrader Valve Options by Joseph Morris

Okay I'm fighting between 4 and 5 stars for this pump. This got me very frustrated when it first arrived because I couldn't get the valve cartridge to stay on the pipe valve on both the Presta and Shrader. It wasn't until I cursed many, many, many times that I realized that the "detent lever" of a valve cartridge is the OPPOSITE of all other types of air cartridges I have used. JE! The picture I've attached shows the valve cartridge in the closed position. I noticed the pump didn't come with any instructions, and if it did, it must have been lost somewhere. But once you figure out the valve cartridge, the pump works great. I can inflate my road bike tires to 100psi with no problem.
