How about some positive news? My son is almost 9 and hasn't ridden a bike without training wheels. He never really took to using a balance bike or anything else and I try not to push him because I don't need him to be into everything I am (spoiler warning, he's not into anything I like lol). Aside from begging me to buy him a Trek a couple of years back, he hasn't been interested in riding. The downside of him being older is that he's gotten so apprehensive about trying to ride with no training wheels and fear of falling. We watched the a cycling weekly video of teaching kids to ride in 45 mins and we went out and tried it the past 2 days. Yesterday he was riding unassisted, although still needs me by his side and is still struggling with control, but he's getting there. We're trying to do it a little every day so he can keep the momentum going.
