When I was a kid I had a big can that help compressed air (my uncle handed it down to me) in case I got a flat while on the road. I'd put in a plug and pump it up. If you ran out of air in the tank you could even take some air out of the 3 good tires and partly fill the tank so you could then ride with 4 semi filled tiers to a gas station.
So does anyone know of a small compressed air tank that you could use (even as a 1 shot deal) on a scoot? not that I want one, will go for the air pump myself, just wondering out loud.
