===============
Blue Mel's lightweight bicycle pump vintage classic racer raleigh carlton dawes. On offer is an old push bike tyre pump. It is made by Bluemels and is marked the Bluemels lightweight. It is white plastic with blue lettering. Length is 16.25" and it is complete with a high pressure racing bike adaptor.

A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or Presta. A third type of valve called the Dunlop (or Woods) valve exists, but tubes with these valves can be filled using a Presta pump.[1]

Several basic types are available:

  • Floor pumps
  • Frame-mounted
  • Compact or mini
  • Foot-operated
  • Double-action
  • Blast or tubeless

In its most basic form, a bicycle pump functions via a hand-operated piston. During up-stroke, this piston draws air through a one-way valve into the pump from outside. During down-stroke, the piston then displaces air from the pump into the bicycle tire. Most floor pumps, also commonly called track pumps, have a built-in pressure gauge to indicate tire pressure.

Electrically-operated pumps intended to inflate car tires (as available in most service stations) can in principle be used to inflate a bicycle tire if the right type of connection is available. Some such pumps are designed to cut off before a suitable pressure (much higher for a bicycle than a car tire), and will much under inflate the tire. Others may not cut off, but deliver a high rate of flow to fill the larger car tire, with a risk of over inflating and bursting a bicycle tire unless it is stopped with split-second timing.

Inflating tubeless tires requires an initial surge of air to seat the bead, and specialized pumps are available specifically for this task.
