tom - I know right?
It is wonderful for people commute and/or ride several times a week. The setup hassle makes it worth while for us.

For casual riders who ride a couple of times a month, its not worth the setup. Changing tires can be a pain too for those that like to do that.

Changing a traditional tire is super easy - using a tiny pump is not. Although I helped someone on the side of the road change a tire a few days ago and was reminded how difficult it can be for people who never do it. ;-)

@ajerichos - they make inexpensive plugs for bikes that are much smaller than a car plug. I've plugged my car a lot, but can't imagine putting something that big in a bike tire.

Darthy - its not a mess unless your tire blows off the rim during initial inflation. That is a real mess! LOL
