There are three types of product for inflating your bike tyres: hand pumps, CO2 gas cartridges, and foot pumps. They are all very useful but do not cover the same needs.
You should choose your bike pump based on 2 criteria: your use (quickly inflating the tyre after a ride or fixing it at the side of the road) and the type of bike you are pumping up.
What do you need a bike pump for? For inflating a tyre, of course! True, but not everyone has the same needs. You might just be re-inflating tyres after a ride, or you may be dealing with an urgent repair miles away from home.
Quickly Inflating Your Tyre After a Ride:
Go for a foot pump or compact foot pump model to make pumping up your tyres quicker and more comfortable (you will push more air into the tyre each time than with a hand pump). Generally, foot pumps will pump to a higher pressure than hand pumps. They also require less effort to use. A foot pump will be more precise: this kind of bike pump generally comes with a pressure gauge so that you can see the tyre's pressure
Repairing Your Bike During a Ride
If you need to carry your pump with you on bike rides, go for a hand pump or CO2 cartridge.
These small, compact solutions are easy to carry in a bag, on your bike's frame or in the pocket of your cycling jersey. In terms of precision, some hand pumps have a pressure gauge for accurately inflating your tyres.
CO2 cartridges are effective and very fast, but can only be used once.
2. The Type of Bike You are Pumping
Don't leave anything to chance: mountain bike and road bike tyres have very different pump requirements. For other bike models (city bikes and hybrid bikes), the choice of pump won't be so strict.
Mountain Bike Tyre:
Go for a pump with a wide body so that you push a large amount of air in each time. This will inflate your Tyre more quickly.
Go for a pump with a thin body that, even though it pumps less air each time, will let you get up to at least 7 bars - the pressure you need for road cycling.
Certain pumps also have a telescopic function for pumping even more air when you first start pumping.
