What is the easiest and quickest way to pump up a tyre? I find that I need to pump up my tyres at least weekly and am looking for how to make this quick and easy. 

So what is the easiest and quickest method of pumping up a bike tyre?

As an example, I found this device recently. (forwarded to the best part)
If you're at home, use a floor pump. They are very easy to use and have a gauge so you can measure the pressure.



When you're on the road, the quickest and easiest way to get you back on the road is to use CO2 cannisters. They are not that cheap though and the CO2 will leak out of the tube faster than air (mostly N2), requiring topping up over the next few days.
