Yeah, same here. I simply HAD to get my hands on a pair of BMX style bars, WITH the crossbar. The crossbar was indispensable. After all, you could maybe bend your bars or something, without one.
Next, I had to get the number plate, and the BMX style grips. Ditched the banana seat for a road bike style seat. And finally, the knobby tires. I was there, man. Still only had one gear and a coaster brake, but I was a happy 13 year-old kid, equipment-wise.
