While riding a bicycle can be enjoyable, getting a flat tire is not, especially if you're on the road and far from a repair shop. However, a variety of bike pumps can make the repair task easier. While some pumps can be carried on the bike, other styles are designed for home use.
Types
The three major types of bike pumps include floor pumps, frame/mini pumps and CO2 pumps. Each type has specific features that provide advantages and disadvantages. Floor pumps are the most efficient pumps, but they won't fit all styles of bikes. Mini pumps can fit in a pocket, bag or pouch on the bike, but may require many strokes to fill a flat tire. CO2 pumps are small and lightweight, but have a higher potential for failure.
Function
Each type of bike pump functions slightly differently. Floor pumps use a piston that draws air through a one-way valve and forces the air into the tire. Mini pumps function similarly, but don't have the same air capacity as the floor pumps, making them less efficient. CO2 pumps simply use the stored carbon dioxide gas in the cartridge to fill up the tire. As a result, most CO2 pumps need to be replaced after use.
Pressure
Monitoring the air pressure on the bike tire can be difficult if you're on a trail away from home or a gas station. Portable tire gauges, however, can test the tire pressure after using the bike pump. Every tire has recommended PSI ranges printed on the side, labeled as "maximum pressure" or "inflate to." Some floor pumps feature built-in gauges that eliminate the need to carry a separate tool while riding.
Considerations
While any bike pump can inflate your bike tire, choose the right bike pump for your riding style. If you prefer a simple, easy-to-use floor pump, make sure the pump is compatible with your bike model. Also, consider the type of valve stem on your tires so the pump will fit the valve -- common valve stems include Schrader and Presto. Most floor models can inflate both types of valve stems.
