When I was about 11-13, I had a young neighbor who I used to ride on my bike. He’d ride in front (I’m still amazed that we both fit on the tiny little seat) and put his feet up on the bar. I still have the bike, and it has ‘scars’ from where he put his feet, hehe… It was soo funny, he was about 4-6 yeard old, and when we got on the bike, he’d say “yeah, bebbay! I’m on my motorcycle!” and “Let’s rock n roll!” before we’d start riding.
I took him to the park and stuff a lot, because I always babysat him. I have to say, it was a LOT quicker riding the bike than trying to get him to keep up on his own bike with training wheels.
