The pump 7

  1. Handle Pulled up and pushed down to work the pump.
  2. Cylinder (barrel) The long tube the piston moves in. Also called the barrel.
  3. Pressure gauge Shows the air pressure in the tire.
  4. Base Stands on the floor. The feet rest on it to hold the pump down.
  5. Hose Carries the air from the pump to the head.
  6. Head Fits over the tire's valve.
  7. Lever Flipped to lock the head onto the valve.

Inside 4

  1. Piston rod Joins the handle to the piston.
  2. Piston Slides down the cylinder and pushes the air out. Also called the plunger.
  3. Piston seal A flexible cup on the piston. Its lip seals against the cylinder wall.
  4. Check valve A one-way valve at the foot of the cylinder. Air passes it one way only.

How this list was compiled: Every name checked on 2026-09-30 and kept only where two independent sources use it. (1) Wikipedia, text only: Bicycle pump, https://en.wikipedia.org/wiki/Bicycle_pump . (2) Four pump makers' documents, each maker counted once and used for names only: floor pump parts diagrams, https://www.parktool.com/assets/doc/product/PFP-4_parts.pdf and https://www.parktool.com/assets/doc/product/PFP-6_parts.pdf ; the service manual of a public bike pump, https://archive.org/details/manualzilla-id-6029113 ; a pump instruction sheet, https://web.archive.org/web/20040702195913/http://www.blackburndesign.com:80/2004/Blackburn_Pump_manual.pdf ; a floor pump announcement, https://web.archive.org/web/20160527213958/http://www.zefal.com:80/mailing/pdf/ZEFAL_CP_PROFIL_MAX_ANGLAIS_LIGHT.pdf . Piston rod rests on the service manual and on Wikipedia's metal rod down the middle of the cylinder; check valve on two makers (check valve ball, check ball in a foot valve) and Wikipedia's one-way valve; head and lever on two makers, with Wikipedia for the lever; every other name on Wikipedia and at least one maker.

How it works

The parts of a bike pump, shown on a floor pump. The first drawing is the whole pump. The second cuts open its lower end to show what moves the air.

Read the full guide

The pump

The handle is at the top of the cylinder, and the base stands on the floor. The pressure gauge sits at the foot of the cylinder. The hose runs from the base to the head, which fits over the tire's valve, and the lever locks the head on.

Cut open

Inside the cylinder, the piston rod joins the handle to the piston. The piston seal closes the gap between the piston and the cylinder wall. The check valve at the foot of the cylinder lets air pass one way only.

  • The cylinder is also called the barrel, and the piston the plunger. The quiz takes either name.

Questions and answers

What are the parts of a bike pump called?

On a floor pump: the handle, the cylinder or barrel, the base, the pressure gauge, the hose and the head. Inside the cylinder are the piston rod, the piston with its seal, and a check valve.

What is the end of a bike pump called?

The head. It is the part at the end of the hose that fits over the tire's valve. On many pumps a lever locks it in place.

How does a bike pump work?

Pulling the handle up draws air into the cylinder through a one-way valve. Pushing it down makes the piston force that air through the hose and into the tire.

What is a floor pump?

A bike pump that stands on the floor on its base. It is also called a track pump, and most have a built-in pressure gauge.
