As for your original question, the Kilo TT is a fine choice for a first fixed gear. Just remember that their sizes tend to be a bit wonky. I can't remember what it is; if a 53 cm fit more like a 50 cm or if a 50 cm fit more like a 53.
I've been told back in the day many kids bikes were actually fixed, cheapest option, and most kids don't really care.
And +1 for the Kilo
