A bicycle pump is a type of positive displacement pump specifically designed for inflating bicycle tires.
Basic types available include:
floor models or track pumps
compact or mini
When picking a pump or inflator be careful to make sure that its head is compatible with your valve. Most are compatible with one or both of the two types of valve in use on bicycles, Schrader or Presta. A third type of valve called the Woods valve exists, but can be pumped using a Presta pump.Full Article
