Electric bike pumps are a good option for bicyclists too, and many attach right onto the bike frames, working quickly and requiring less effort.Video Games (Accessories and Games) 15 Days Returnable If you choose a floor pump, ensure the base is wide and sturdy otherwise, it could fall over. You can also use well-made floor bike pumps to inflate other tires and things like inflatable pool toys. Many people inflate bike tires by how full they feel but you may feel more comfortable getting a hard number. ![]() Tires have different inflation ratings, so you’ll want to know what yours is before using a pump, and then keep an eye on the gauge. It should attach easily to either kind of valve without making you have to work too much, so look for ones that adjust automatically. The two most common bike tire valve types are Presta and Schrader, so you’ll want a pump that works with both. It’s good to have a maximum of 160 pounds per square inch for floor pumps. Smaller, handheld manual bike pumps usually can’t perform like this and must be pumped more. Some pumps also have pressure gauges, which show the tire’s air pressure as you use them.įloor bike tire pumps, meanwhile, have bases that sit on the floor and can deliver highly compressed air. This airflow starts the compression process, and when the pump’s internal air pressure gets higher than the tire’s inter pressure, the pump’s outlet valve opens, and the air gets forced into the tire. The internal air pressure gets lower than the external air pressure, causing the pump to suck in air from the outside into the cylinder through a suction valve. It has a piston inside that moves up and down as you work the handle, it creates a vacuum inside the pump’s cylinder. A manual bicycle pump is a pretty fascinating little machine.
