I wanted to be able to get a 24" bmx race bike as well as a new 20". Had to have kids so I had an excuse to keep buying bikes (and a playstation, yet to buy one though). Had a daughter, mrs said no bmx for her, dolly's & clothes. So I went again and got a son.
No, seriously we though it was never going to happen after a few years fo trying. Even the doc said so. We just went for it then, ended up with 2 in justs over 2 years.
I am looking at micro mini bmx & a new 24" race bike though.
