It's probably best to carry two source of air when riding, especially long dist and even more so riding solo. I have a co2 pump and a bicycle hand pump on the bike at all times. And longer rides I'll take the 12v pump. The co2 pump doesn't really do the job by itself, and I've never tried using the bicycle pump. And with a 12v pump getting tossed around, I guess that's not guaranteed to work when needed. So my question is, has anyone used a bicycle pump on a motorcycle tire? Will it work? And is there a good quality hand pump that's compactable to carry on the bike?
