I use a litle foot pump sold by Hein Gericke called "Bikers Dream". Admittedly I never knew a biker that dreamed of footpumps but there clearly must be a pump fetishist who's designed the thing.
It's about half the size of a spectacles case but thicker, and just weighs a few ounces.
I personally wouldn't have an electric pump as they're bulky, heavy and burn out just when you need them. usually on the first time they're used.............. seen it happen several times.
Cue everyone chiming in with their electric pumps wot's never let them down.....
