The bicycle pump sizes is not something that buyers usually look at. The first thing they usually check is the pump capacity. However the sizes are important if space is limited. You will see pumps measuring 27.5 x 9.5 x 5.5 inches, 26 x 8 x 4 inches and 28 x 10 x 4 inches.
These are pumps that are manually operated. They are used to inflate bicycle tires. A lot of these pumps are very light so they are easy to use. It will only take a few minutes to inflate a single tire.
Although there are different designs, almost all of them are very easy to use. Because of the compact bicycle pump sizes, it makes finding storage space easy.
Two types are available: the floor pump and hand pump.
The floor pump base is set on the surface next to the tire that has to be inflated. The hose is connected to the bicycle air valve. A piston goes down and up in the pump. The movement is made possible by a handle over the pump. The piston pushes air in the tire tube, increasing the tire dimensions.
This device functions by utilizing a piston to put air inside a hose which goes into the tire tube. What sets it apart from the floor pump is you can hold it. This pump is preferred by those going on a bicycle trek. These are compressed enough you can put them in a backpack.
Both of these pumps are fitted with a gauge so you can get an idea of the air pressure going inside the tire. This way you will know if it is getting enough air. By using the gauge, you will keep the pump from putting in too much air. Excessive air can damage the tire and tube.
Battery Powered Pumps
These are derived from the manual pumps. Aside from using batteries, this device has a safety feature; it will stop the air from flowing once a specified air pressure level is attained. These are more expensive than the standard pumps. But they are ideal for people who get tired with manual pumping.
The pumping capacity is not indicated by the pump dimensions. There are some small pumps that do 160 psi. Others max out at 100 psi. The right size will depend on how many bikes you are working with. It also depends on what bikes you have.
