1. HAND AND FOOT ACTIVATED: This hand and foot activated design makes pumping easier and faster than normal handoperated frame pumps, allowing you to inflate your bike with less effort and time. It can easily withstand pressures up to 80 PSI. 2. DOUBLE VALVES: Our portable floor pump features Presta and Schrader valves without affecting the conversion components. It works not only for bicycles but also for electric vehicles and motorcycles (for emergencies only). It can be used to inflate balls, balloons, swimming rings, inflatable boats, etc. 3. LIGHTWEIGHT AND PORTABLE: This mini bike pump is made of an aluminum alloy cylinder, compact (about the size of a mobile phone and smaller than a water bottle). Weighing only 300g, it's easy to carry anywhere and store in a bike bag to save space. 4. DURABLE AND STABLE: The removable rubber hose and freezeresistant, temperatureresistant inner and outer tubes are made of strength aluminum alloy for enhanced wear resistance and a smooth surface. The widened platform features nonslip rubber for added convenience.
