Congrats to your little guy. He couldn't look more proud. Balance biking is a magical time, but believe it or not, it only gets better. Nice green 1x1, too. Looks like you shoehorned an Endomorph on the front, but what's the rubber on the rear?
I fit a nokian gazzaloddi 3.0 in back on a drilled out sunringle doublewide rim.Even with the knobs trimmed down a bit the gazza is kind of like a mini-Nate. All the traction is nice when you've only got one gear.
