customer: "hi, i got a flat tire. i need to buy a tube."
ken: "ok, what size tire?"
customer: (pointing)"its that exact bike right there."
ken: "alright, here you go."
customer: "are there any tricks to changing a flat? like without taking the wheel off the bike?"
ken: "WHAAA???! sure. here's the trick: take the wheel off the bike."
customer: "yeah, but it seems easier to leave the wheel on there, like if you were in a race or something?"
ken: "thats impossible. think about it. the tube is completely round and the wheel is enclosed in the rear triangle."
customer: "what if you disconnect this part right here (pointing at quick-release)?"
ken: "i suppose that could be done, but you are making it a lot harder than just taking off the wheel, removing the old tube, replacing with a new one, and putting the wheel back on. you would have the entire bike in the way of working on the wheel."
customer: "ah i see."
ken: "i'd recommend looking online for a how-to tutorial with pictures to show you how to do it. that way you will get it right the first time."
customer: "ok, thanks!"

fly bikes (bmx) was trying to develop "cobra" tubes for a while. they're lineear tubes the length of the circumference of the wheel, so you can change a tube without using tools. they haven't made it to production yet.
