LITH, kid has a flat. of course I have tubes in every size, including sizes i dont have bikes for., but not a 24". Go into neaest store which is unfortunately 99 bikes. grab a patch kit and wait at the counter. Only person at the counter is ringing up another customer. but wait they want to look at some other accessory. now they're done. But he's going to get someone to check the bike. no he's going to do it himself. 10 minutes of waiting I just gave up and went elsewhere for a tube to get the kid riding, ordered a new patch kit from amazon
