My 6yo just rode his bike without training wheels
Dude. DUDE. After like 3 weeks of practice he just took off down the driveway without me holding on and made it all the way to the mailbox. My wife was inside and I literally yelled loud enough that she came running thinking something was wrong lol. He did a little wobble at the end but kept it upright. We're talking about this moment for the next 20 years I guarantee it.
Dude that's awesome. Those milestones are the real wins. Next thing you know he's gonna want to go on longer rides and you're buying better gear. The training wheels phase is officially over. Time to embrace the new adventures.
