I didn't think it would ever happen, this bike riding thing. He has not been interested in learning at all, ever. "Hey Adrian, want to ride bikes?" "Nope. I'm a farmer. Farmers don't need bikes!" He'd spend hours pedaling his John Deere pedal tractor around, though. Same one my brother had decades ago. Just last month, the front wheels on that pedal tractor rusted out and fell off. Too much use. We have yet to fix it.
Enter bicycle. Rather quickly he learned once he gave it a shot. He loves it now.
Little miss adorable likes watching him too.
