Mini Fumpa Bicycle Pump
No one wants to use a hand pump on the side of the road. Compressed air canisters work in a pinch, but they're not reusable. The Mini Fumpa Bicycle Pump can get you back up and running in under a minute, no waste required. It weighs under seven ounces, fits in a pocket, and is powered by a rechargeable battery that can inflate a single tire up to 120 psi or a pair of tires up to 100 psi each. It works exclusively with Presta valves, while the full-size Fumpa trades size and weight for added compatibility.
